Separate the Acceptance Stages
Use the purchase specification to distinguish three decisions:
| Stage | Question to resolve | Suggested evidence |
|---|---|---|
| Factory inspection or testing | Does the supplied package meet the agreed requirements that can be checked at the factory? | Inspection records, measurements and applicable functional-test results |
| Installation and commissioning | Is the installed equipment ready to operate under the specified conditions? | Installation checks, interface checks and commissioning records |
| Process-performance acceptance | Does the operating system meet the agreed treatment or output requirements? | Results obtained under the agreed feed, operating and sampling conditions |
These are suggested procurement categories. The contract should define the applicable stages, terminology and approval responsibilities.
Specify Factory Checks Item by Item
Ask the supplier to identify which checks are included in the quotation and which need additional arrangements.
Depending on the equipment scope, the inspection plan may address:
- Equipment identification and correspondence with approved drawings.
- Dimensions and connection locations.
- Specified materials and supporting documents.
- Purchased components and their identification.
- Applicable control, alarm or functional checks.
- Packing, loose items and shipment documentation.
For each check, state the requirement, method, record and responsible party. Identify any test conditions that differ from the intended installation.
Avoid a single checklist item called “quality approved” without defining what was examined.
Record What the Factory Test Cannot Establish
Ask the supplier to state the limits of the proposed demonstration.
If actual wastewater, exhaust gas or waste material will not be available, record which process requirements remain unverified. If the test uses temporary connections or simulated inputs, identify them in the report.
An inspection release should state exactly what it authorizes. Do not assume that permission to ship also closes every performance requirement.
Plan Site Acceptance Around Actual Conditions
Site testing needs its own agreed basis, including the feed or process conditions, operating configuration, measurement locations and acceptance criteria.
For local exhaust ventilation, HSE’s commissioning guidance calls for documented operating conditions and qualitative and quantitative assessments. This illustrates why an installed-system assessment needs more than a record that individual components were delivered. HSE: Commissioning an LEV system
For other equipment categories, ask the responsible engineer to define the relevant checks rather than copying a ventilation checklist.
Identify who provides utilities, representative feed, operators, sampling arrangements and test instruments. Record any prerequisites that must be satisfied before the test can begin.
Agree on the Handling of Open Items
A proposed acceptance record should distinguish completed checks from unresolved items.
For each open item, record the requirement, observed issue, responsible party, corrective action and required confirmation. State whether it affects shipment, installation, operation or final acceptance.
Agree on how any retest will be reviewed. Keep the acceptance decision tied to the documented results and contractual scope.
Frequently Asked Questions
Is a factory acceptance test required for every purchase?
The required inspection and testing scope should be agreed for the equipment and project. A label such as “FAT included” does not explain the actual checks.
Does a successful factory test prove treatment performance?
Only the requirements demonstrated under the recorded test conditions are supported. Identify any performance requirements that still need verification.
Can video replace an inspection report?
Specify what the video must show and which records must accompany it. Do not leave the evidence requirements undefined.
Who signs the final acceptance?
Name the authorized parties and approval stages in the contract or agreed inspection plan.
Prepare the Acceptance Plan with the RFQ
Our manufacturing and equipment supply capabilities page describes project-specific inspection and documentation arrangements.
Include the proposed checks, required records and approval responsibilities in the RFQ. Ask bidders to identify exclusions and unresolved requirements before the purchase scope is finalized.
