How to check a test centre’s capabilities

Check test method, conditions, instrument traceability and report scope, not just the centre name.

Short answer

Before requesting a test, ask in writing which quantities and methods the centre measures and whether the specific test falls within its scope. Fix model, load, ambient conditions, sensor location, instrument ID and acceptance criteria in the protocol. Check whether the report includes raw data, uncertainty and calibration/traceability details. A laboratory’s capability is not approval or route assurance for every product.

A test centre’s promotional description alone does not show that a specific test is within scope. Confirm in writing before requesting work that the property and method fit the decision you need to make.

The protocol should identify sample/model, load arrangement, starting conditions, ambient conditions, sensor location, measurement interval and acceptance criteria. Check for instrument ID, calibration/traceability details and, where available, measurement uncertainty in the report.

If accreditation or competence is claimed, check the current scope list for the relevant method and measurement field. Interpret results only for the tested configuration and conditions; they do not automatically verify catalogue duration or real-route performance.
