Site Acceptance Test (SAT) Checklist Template

Prove new equipment works at your site: installed correctly, safe, connected to your systems and running to the agreed performance on your own materials, before you accept it.

This free site acceptance test (SAT) checklist is for project and engineering leads, test engineers and operations teams accepting a new machine, process skid or control system at their own site, and for the vendors who install it. One run is one SAT after the equipment is delivered and installed, planned from the first day of the tests on site. It starts with what the contract says and a protocol both sides agree, often built from the FAT protocol, and carries over any FAT punch items. Site readiness covers the delivery, the schedule, safety rules for the vendor’s team, test materials and calibrated instruments. The tests check the installation and utilities, prove the emergency stops, guards and fault responses, test the links to connected equipment and systems, and run the equipment on your own materials. Failures are fixed and retested, open items go on a punch list with owners and dates, and the operators are trained and the documents handed over. The project lead decides acceptance, and the equipment is handed to production or, on a GMP site, to qualification.

Where the SAT Sits Between the Factory and Production

A site acceptance test (SAT) checks new equipment at your own site after it has been delivered and installed: does it still work after transport, connected to your utilities, your other equipment and your systems, running on your own materials? The customer runs it with the vendor, against a protocol both sides agreed, and it ends in a decision to accept the equipment, accept it with punch items, or not accept it yet. This checklist runs one SAT.

The test at the vendor’s works before shipping is the Factory Acceptance Test (FAT) Checklist; this checklist picks up its report and open punch items. On a GMP site, the Equipment Qualification (IQ/OQ/PQ) Checklist runs alongside: quality witnesses the SAT and records the results it relies on, then runs IQ, OQ and PQ. Commissioning a whole building’s systems is the Building Commissioning Checklist, and signing off a software build against business requirements is the User Acceptance Testing (UAT) Checklist.

Before shipping

Factory acceptance test

Where: at the vendor’s works, before the equipment is packed.

Proves: it was built and works as specified, with simulators where your plant is not connected.

Output: a signed FAT report and the punch items left for site.

This checklist

Site acceptance test

Where: at your site, after delivery and installation.

Proves: it still works after transport, safely, connected to your utilities and systems, and to the agreed performance on your own materials.

Output: the acceptance decision, a punch list with owners and dates, and the equipment handed over.

GMP sites

Equipment qualification

Where: at your site, after the SAT, under your quality system.

Proves: through IQ, OQ and PQ, that the equipment is fit for GMP use.

Output: qualified equipment released by quality. It can rely on SAT results where justified.

What the Site Acceptance Test Checklist Covers

Nine phases take one SAT from the agreed protocol to the handover. The first task records the first day of the SAT on site, which sets every due date, and asks whether a FAT was held, whether the equipment connects to other equipment or systems, whether it is GMP equipment and where it is installed. A connected machine adds the integration tests in Phase 5, a failed test adds a fix and retest, and the answers add tasks for the FAT report and its open items, GMP qualification and punch items closed after acceptance. The acceptance decision in Phase 8 is assigned to the project lead alone, and nothing after it can be completed until it is made.

  1. Phase 1

    Phase 1: Scope & SAT Protocol

    8 tasks

    Agree what the site acceptance test will prove, and how, well before the vendor’s engineers arrive. The protocol often starts from the FAT protocol: the tests to repeat after transport, the tests that can only be run on site, and the FAT punch items to close here. The protocol is approved last, once the FAT review, the deviation categories and, on a GMP site, quality’s needs are settled. Every due date counts from the first day of the SAT on site.

    • Record the equipment, the SAT start date and the people — the equipment and its tag or serial numbers, the purchase order and the vendor, where it is installed, the first day of the SAT on site, whether a FAT was held, whether it connects to other equipment or systems, and the four people this checklist assigns
    • Confirm what the contract says about the SAT — who runs and pays for the SAT, the vendor’s people and days on site, what site acceptance triggers under the contract (a payment, the start of the warranty, the transfer of risk), any retention, and the time allowed to close punch items
    • Review the FAT report and the results the SAT relies on — the signed FAT report, its outcome, the tests passed at the vendor’s works that the protocol does not repeat, and any condition the FAT sign-off set for the site
    • Carry the open FAT punch items into the SAT — each item left open at the FAT, its category and owner, and whether it is to be closed before the SAT, during it or after acceptance
    • Add the factory checks to the SAT protocol — with no FAT, the documents, the inspection against the drawings, the I/O and alarm checks and the functional tests are done on site for the first time, so the protocol and the schedule allow for them
    • Agree the deviation categories and who can accept them — how a deviation found at the SAT is graded (for example, must be fixed before acceptance, can be closed after acceptance by an agreed date, or an observation), and who on each side can accept a deviation or a concession
    • Agree with quality which SAT results qualification will rely on — the SAT tests that installation and operational qualification will rely on rather than repeat, quality’s review of the protocol, and the documentation rules the vendor’s and your testers follow
    • Agree the SAT protocol and acceptance criteria — every test with its method, the expected result, the acceptance criterion and who witnesses it, the FAT tests to repeat after transport and installation, the tests that can only be run on site, and approval by both sides before the SAT starts
  2. Phase 2

    Phase 2: Site Readiness

    6 tasks

    A site that is not ready loses SAT days: utilities not connected, test materials missing, instruments out of date or the vendor’s team not inducted. Check each one before the vendor’s engineers travel.

    • Confirm the equipment arrived complete and undamaged — every crate and loose item against the packing list, any transport damage photographed and reported to the vendor and the carrier, and the equipment stored or installed as the vendor’s instructions say
    • Agree the SAT schedule and who attends — the order of the tests day by day, the vendor’s engineers and your operators, maintenance and quality staff needed, any third-party inspector, and who signs each test record
    • Confirm the vendor’s method statement and the software to be tested — the vendor’s method statement and risk assessment for its work on site, its test procedures, and the software version it will load, the same as the one accepted at the FAT or with every change since listed
    • Agree the site safety rules and isolation for the vendor’s team — the site induction, the permits the work needs, who may isolate and energise the equipment, how locks and tags are used while tests run, and the emergency arrangements
    • Arrange the test materials, product and utilities for the tests — the site’s own raw materials, packaging or product in the quantities the performance run needs, what happens to the output, and the utilities booked for the test days
    • Check the test instruments are calibrated — every instrument the protocol uses, such as meters, gauges, scales and data loggers, in date for calibration, with its certificate to hand
  3. Phase 3

    Phase 3: Installation & Utilities Check

    4 tasks

    Before anything runs, check the equipment is installed as designed and connected to the right utilities. Transport and installation are where damage, loose connections and missing guards appear.

    • Check the installation against the drawings — position, levelling and anchoring, access for operation and maintenance, every guard and cover refitted after transport, and the layout against the approved drawings
    • Check the utilities connections — electrical supply and earthing, compressed air, water, steam, drainage and extraction connected and measured against what the specification asks for
    • Check the cabling, piping and instrument connections — cables, terminations, pipework and instrument connections made and labelled as the drawings show, and every signal checked from the field device to the controller
    • Power up and check the equipment starts safely — the equipment energised under the agreed isolation rules, the software version loaded checked against the one agreed, and the equipment starting in a safe state with no unexpected movement
  4. Phase 4

    Phase 4: Safety, Interlock & Functional Tests

    5 tasks

    Prove every safety function on site, as installed, then run the equipment’s own functional tests before it is tested with the equipment and systems around it. A safety function that passed at the FAT can fail after transport or when wired into the site.

    • Test the emergency stops — every emergency stop stopping the equipment as designed, and a reset not restarting it without a separate start command
    • Test the guard interlocks and safety devices — each interlocked guard, light curtain, two-hand control, pressure relief and other safety device doing what the protocol says when tested
    • Test the alarms and the response to faults — each alarm in the protocol raised and shown, and the equipment going to a safe state on loss of power, air or a signal, and on a sensor failure
    • Check the guarding, access and markings as installed — fixed guards secure, no gaps created by the installation, safe access for operation, cleaning and maintenance, and the warnings and markings fitted
    • Run the functional tests in the protocol — each operating mode, start-up and shutdown sequence, format or recipe change, and the operator screens, run and recorded against the protocol
  5. Phase 5

    Phase 5: Integration Tests

    4 tasks

    Applies only when the equipment connects to other machines, the line’s controls or site systems. Prove the signals, interlocks and data links work with the real equipment around it, which the FAT could only simulate.

    • Test the signals to and from the site’s control system — start, stop, ready and fault signals, recipe or format selection and status reported both ways, as the interface specification says
    • Test the interlocks with the equipment upstream and downstream — an emergency stop or fault on this equipment stopping the equipment it should, and theirs stopping this one, with a safe restart
    • Test the data links to site systems — counts, alarms, batch or production data and recipes passing correctly to and from the site’s supervisory, production or business systems, under the site’s network and security rules
    • Run the line with the new equipment in it — the whole line or system running together at the agreed speed, with hand-offs between machines working and no unexpected stops
  6. Phase 6

    Phase 6: Performance Run on Site Materials

    3 tasks

    Run the equipment as production will, on your own materials, and measure it against the acceptance criteria. This is the test the FAT could not fully run.

    • Run the performance test on your own materials — the rate, yield, uptime and other measures in the protocol, run at the agreed speed for the agreed duration on the site’s own materials, and the results recorded
    • Check the quality of the output — samples of the output checked against your specification by the people who will check it in production, and the results recorded
    • Record the results and grade the deviations — every test result against its criterion, each deviation graded in the categories agreed in Phase 1, and any test that failed
  7. Phase 7

    Phase 7: Deviations, Retests & Punch List

    3 tasks

    Fix what failed and repeat the test in full, list everything else on one punch list with an owner and a date, and record any deviation accepted without a fix.

    • Fix and repeat the failed tests — the cause of each failure found and fixed by the vendor, the whole test repeated and witnessed, and the new result recorded beside the old one
    • Build the SAT punch list with owners and dates — every open item from the tests, the installation checks and the FAT, with its category, the owner on each side and the date it will be closed by
    • Record any deviation accepted without a fix — each deviation both sides agree to accept as it is, why, any limit it places on use, and who on each side accepted it
  8. Phase 8

    Phase 8: Training, Documents & Acceptance

    7 tasks

    Before acceptance, your people are trained, the documents are handed over and both sides agree the SAT report. The acceptance decision is assigned to the project lead alone, and nothing after it can be completed until it is made.

    • Train the operators and maintenance staff — operation, cleaning, changeovers, fault finding and routine maintenance, given by the vendor, with who attended recorded
    • Collect the as-built documents, manuals and software — as-built drawings, operating and maintenance manuals, the spare parts list, a backup of the software and any licences, test certificates, and the declaration that came with the equipment
    • Check the spare parts and maintenance needs — the spare parts delivered against the list, the parts to hold in stores, and the vendor’s maintenance tasks and intervals
    • Write the SAT report — the tests run and their results, the deviations and retests, the punch list, any concessions, training and documents, and a recommendation on acceptance
    • Agree the SAT report with the vendor — the vendor’s site lead reads the report and the punch list and signs that they agree, or records what they dispute
    • Put right what stopped acceptance, then ask for the decision again — after ‘Not accepted’ only: the vendor fixes each point the project lead recorded, the affected tests are repeated and recorded, and the project lead is asked to change the decision and complete the acceptance task; if the SAT is moved, change the date on the first task (and complete the first task again)
    • Decide site acceptance and sign the SAT report — the project lead reviews the report, the punch list and the concessions and decides whether the site accepts the equipment
  9. Phase 9

    Phase 9: Handover

    6 tasks

    Hand the accepted equipment to the people who will run it, or on a GMP site to qualification, record what acceptance triggers under the contract, and close the remaining punch items.

    • Hand the equipment over to production — the operations lead takes responsibility for the equipment, with the operating procedures, the trained operators and the date it goes into production agreed
    • Hand the equipment over to qualification — the SAT report, the results qualification relies on, the documents and the punch list passed to the validation team, and the equipment kept out of GMP use until it is qualified and released
    • Record what site acceptance triggers under the contract — the acceptance date sent to purchasing and finance, any payment or retention it releases, and the warranty start date the contract gives
    • Add the equipment to the maintenance and calibration plans — the equipment and its instruments added to the asset register, the planned maintenance schedule and the calibration programme
    • Close the remaining punch items — after ‘Accepted with punch items’ only: each item closed by its owner by the agreed date, checked by the test lead, and the punch list marked complete
    • File the SAT records and record lessons — the protocol, test records, punch list, report and decision kept together with the equipment’s records, and lessons for the next FAT and SAT noted

What the Rules Say Before Installed Equipment Goes Into Use

No single rule requires a site acceptance test, but several decide what is checked before new equipment goes into use. Use the table as a starting point.

Topic What the source says At the SAT
Inspection after installation (Great Britain)PUWER 1998, regulation 6: where the safety of work equipment depends on the installation conditions, it is inspected after installation and before being put into service for the first time, to ensure it has been installed correctly and is safe to operate. The result is recorded and kept until the next inspection is recorded.Phase 3 records the installation check. Decide with your competent people whether it is the regulation 6 inspection or a separate one.
Information and training (Great Britain)PUWER 1998, regulations 8 and 9: people who use or supervise the use of work equipment have adequate health and safety information, written instructions where appropriate, and adequate training in its methods of use, risks and precautions.Phase 8 records the training given and the manuals received before the equipment goes into use.
Instructions and declaration (Great Britain)Supply of Machinery (Safety) Regulations 2008, regulation 7(2): before machinery is placed on the market or put into service, the responsible person provides the information needed to operate it safely, such as instructions, and a copy of the declaration of conformity accompanies it. Regulation 8: partly completed machinery comes with assembly instructions and a declaration of incorporation.Phase 8 checks they arrived. The duty is the responsible person’s: the manufacturer or its authorised representative (regulation 2). The FAT checklist covers what to agree before shipping.
Testing under lockout (US)29 CFR 1910.147(f)(1): where lockout or tagout devices are temporarily removed to energise and test a machine, clear it of tools and materials, remove employees, remove the devices, energise and test, then de-energise and reapply the controls. (f)(2): the on-site and outside employers inform each other of their lockout or tagout procedures.Phases 2 and 3 agree isolation with the vendor’s team and record the power-up.
GMP equipment (EU)EU GMP Annex 15, sections 3.4 to 3.7: equipment may be evaluated at the vendor before delivery; where appropriate and justified, documentation review and some tests need not be repeated at IQ or OQ if it can be shown that transport and installation do not affect the functionality; the FAT may be supplemented by a SAT after receipt at the manufacturing site.Phase 1 agrees with quality which SAT results qualification relies on; Phase 9 hands over to qualification.
Automation systems in the process industryIEC 62381:2024 (edition 3) sets out requirements and checklists for the factory acceptance test, the optional factory integration test, the site acceptance test and the site integration test of automation systems in the process industry. It is a paid standard and is not quoted here.A basis for the protocol of a control or automation system, if you work to it.

Where this comes from. PUWER 1998 regulation 6, regulation 8 and regulation 9, and the Supply of Machinery (Safety) Regulations 2008, regulations 2, 7 and 8, on legislation.gov.uk; HSE’s inspection of work equipment page; 29 CFR 1910.147 on eCFR; EU GMP Annex 15 (2015); and the IEC webstore entry for IEC 62381:2024 (its summary). All read on 9 November 2026. No law sets out how to run a SAT: the protocol you agree with the vendor does that. Northern Ireland has its own work equipment regulations. This is a starting point, not legal advice.

Why Run Site Acceptance Tests in CheckFlow?

1

No handover before acceptance

The acceptance decision is assigned to the project lead alone, and the checklist halts there: the handover, the contract milestone and the records cannot be completed until it is made. Not accepted shows a task above the decision; leave the decision open until the points are put right.

2

Only the tests this equipment needs

Answers on the first task add the integration tests for a connected machine, the FAT report review and its open punch items, the factory checks when no FAT was held, and the GMP steps. A failed test adds a fix and retest, and acceptance with punch items adds the task to close them.

3

The vendor’s steps, assigned

Name the project lead, the test lead, the vendor’s site lead and the operations lead on the first task, and every step is assigned from those fields and dated from the first day of the SAT. The vendor’s site lead can be invited as a Guest, who opens and completes only the tasks assigned to them (CheckFlow docs). Track every SAT in progress in the Reports Grid.

CheckFlow does not test equipment or set your acceptance criteria: that stays with your engineers, the vendor and the protocol. CheckFlow makes sure every test is run, witnessed and recorded in order, by the right person, with the evidence kept together.

Test the equipment at the vendor’s works first with the Factory Acceptance Test (FAT) Checklist, take a change to a hazardous process through the Management of Change (MOC) Checklist, and once it is in service, run it with the Preventive Maintenance Checklist and the Equipment Maintenance Workflow Checklist.

Frequently Asked Questions

What should a site acceptance test checklist include?

An agreed SAT protocol with acceptance criteria, the FAT report and its open punch items, site readiness (delivery, schedule, safety rules, test materials, calibrated instruments), the installation and utilities checks, the safety and interlock tests, integration tests with connected equipment and systems, a performance run on your own materials, deviations and retests, a punch list with owners and dates, training, documents, the SAT report signed by both sides and the handover. This template covers those steps for one SAT.

What is a site acceptance test (SAT)?

A test of new equipment at the customer’s site after it has been delivered and installed, run by the customer with the vendor against an agreed protocol. It checks that the equipment still works after transport, is installed correctly and safely, works with the site’s utilities and systems and meets the agreed performance on the site’s own materials. It ends in the customer’s decision to accept the equipment, with or without punch items.

Who signs off a site acceptance test?

Both sides sign the SAT report: the vendor’s site lead to agree the results and the punch list, and the customer’s project or engineering lead to accept the equipment. Who may accept a deviation or a concession on each side is agreed before the tests. In this template the acceptance decision is assigned to the project lead named on the first task, and only they can complete it.

Is a site acceptance test a legal requirement?

No law requires a SAT as such; the contract and the protocol do. Some rules overlap with it. In Great Britain, PUWER regulation 6 requires work equipment whose safety depends on the installation conditions to be inspected after installation and before first use, with the result recorded, and regulations 8 and 9 require information and training for users. Your contract may also tie a payment or the warranty start to acceptance.

Which FAT tests should be repeated at the SAT?

The protocol decides. Tests that transport or installation could affect, such as safety functions, connections and alignment, are repeated on site, along with the tests only the site can run: utilities, interlocks with other equipment, data links and a performance run on your own materials. On a GMP site, EU GMP Annex 15 (section 3.6) allows some FAT tests not to be repeated at IQ or OQ where that is justified and it can be shown that transport and installation do not affect the functionality.

What happens if a test fails during the SAT?

The failure is recorded and graded, the vendor finds and fixes the cause, and the whole test is repeated and witnessed. Minor deviations go on the punch list with an owner and a date. At the end the project lead accepts the equipment, accepts it with punch items to close by agreed dates, or does not accept it yet, in which case the decision is left open until the points are put right.

What is a site integration test (SIT)?

A test of how the equipment works with the systems around it on site: signals to and from the control system, interlocks with machines upstream and downstream, and data passed to supervisory or business systems. IEC 62381:2024 treats it as a separate stage for automation systems in the process industry. This template runs those tests in Phase 5 when the equipment is connected.

Does site acceptance start the warranty?

Only if the contract says so. A contract may tie a payment, the release of a retention, the transfer of risk or the start of the warranty to site acceptance, or to something else, such as delivery or a period in production. This template reads those terms before the protocol is written and records what acceptance triggered after the decision.
