Read what the record says was tested
A pass result is useful only when it can be matched to the delivered tank or device and the activity performed. Check the identity, method, conditions and acceptance basis before relying on the result.
Containment testing, compartment capacity calibration, delivery-meter checks and service work answer different questions. Different procedures, authorities or qualified organizations may control them. Keep the records separate so one certificate is not used to support a claim outside its scope.
Match identity, method and exception closure
A generic batch record or unidentified instrument weakens the link to the vehicle being accepted. The record should show which compartments, pipes and devices were covered, what was found, and whether corrective work was verified before release.

| Decision | What to establish | Condition or limit |
|---|---|---|
| Identity | Match vehicle, tank, compartment and device identifiers. | A generic batch record may not prove project applicability. |
| Method and condition | Record procedure, medium or condition and acceptance basis. | Do not infer a method from a pass label. |
| Instrument | Identify relevant equipment and calibration status. | An unidentified instrument weakens traceability. |
| Result and closure | Record result, exception, repair and approval. | Open exceptions prevent clean release. |
Which calibration record do you need?
A compartment capacity table relates the tank’s measured volume to its stated reference conditions. A delivery-meter record concerns the measuring system used during transfer. If the order includes both, request both records and check the tank, compartment and meter identifiers separately. Neither replaces a required containment inspection.
Before commissioning, ask the local legal-metrology authority or qualified provider which checks, seals and records apply to the intended transaction. Obtain the applicable procedure and due dates from that provider. A U.S. reference or a record from another meter is not approval for your installation.
Ask for the applicable records rather than recreating the tests
Agree the document package with the responsible authority or qualified provider. Retain the unit identities, procedure references, instrument status, results and unresolved findings. This purchasing guide intentionally provides no test pressure, medium, sequence or repair instructions.
Information to prepare for this review
- Tank and vehicle identity
- Required test, calibration and service scope
- Applicable procedure or authority basis
- Compartments, piping and devices covered
- Instrument and certificate requirements
- Exception and approval workflow
Records to request and keep
- Vehicle, tank and device identity match
- Procedure, date and test condition
- Instrument identity and calibration status
- Result, exceptions, repair and approval chain
Common mistakes and what to check instead
- Accepting a certificate with no vehicle identity: Require a traceable link to the delivered tank and devices.
- Treating calibration as a leak test: Keep each activity and acceptance scope separate.
- Recreating a hazardous test from an online guide: Use qualified organizations and the applicable controlled procedure.
Scope of this guide
This page intentionally does not give test pressure, medium, sequence or repair instructions.
Applicable authorities and qualified service providers control the work.
Remove the tanker from service for leakage, damaged containment, expired required status or an unresolved safety-critical exception.
Sources and applicability

Provides public checklists and worksheets; the signed project documents remain controlling.
Defines the relevant product family and published configuration boundaries. Project-specific ratings require the selected OEM documents.
Official U.S. reference for continuing qualification and maintenance of hazardous-material packagings. It is not a global approval basis.
Primary U.S. metrology reference with a dedicated vehicle-tank meter code. Local legal-metrology requirements may differ.
