Coating Test Sample Identity: Distinguish Supplier Code from Laboratory Code

A laboratory's sample code and a supplier's product code serve different roles. Preserve the mapping between them so that a report can be connected to the correct coating, batch and preparation history.

Updated · NANOLAB Knowledge

The key distinction

A laboratory may assign an internal identifier after receipt. That identifier should not replace the original identity record or become a new commercial product name. The handover needs enough information to trace the tested material while respecting any agreed blind-evaluation arrangement.

Practical checks

  1. Record the supplier product and batch identity before shipment.
  2. Reconcile the laboratory receipt code with the submitted sample list.
  3. Check the mapping when the final report arrives and before publishing a summary.

Example

Illustrative example: several coded coating samples are sent together, and the report uses only laboratory numbers. Without a verified mapping, the buyer risks assigning a favourable result to the wrong product. Resolving the identity before interpretation is more important than immediately comparing the reported values.

Scope and limits

Do not reconstruct a missing mapping from expected performance or bottle appearance. If identity cannot be established, state that limitation and obtain an appropriate resolution. This guide concerns traceability and does not authorize disclosure of confidential formulation information to an unapproved recipient.
