Quick answer: List the accepted scope, unresolved items and conditions that must be met before production release.

How should conditional sample approval be recorded?

Approval of fit does not automatically approve durability or environmental performance. Mark each completed check and link its evidence. Keep an unresolved requirement visible rather than describing the entire sample as fully accepted because one trial worked.

A practical verification method

Review open items against the release criteria and record the authority and scope of any conditional decision.

ItemWhat to recordPurpose
Reference configurationPart or assembly identity and drawing revisionMake comparisons traceable

Use the result in an engineering request

Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
