Direct answerAn approved sample should have a unique identifier, frozen configuration, test record, document matrix, artwork status, defect notes and authorized signatures. Keep a retained reference and require written approval before production changes any controlled part or function.

Identify the exact sample

Sample code, model, date, hardware and firmware revision.
Power input, plug, controls, accessories and radio module where applicable.
Colour, finish, materials and water-contact components.
Photos of rating label, packaging, internals where agreed and distinguishing details.

Link approval to evidence

Approval area	Required record
Specification	Signed version with measurable limits and permitted tolerances
Performance	Raw results, method version, sample count and disposition
Compliance	Model–document matrix and unresolved gaps
Appearance	Colour, finish, workmanship limits and approved images
Packaging	Artwork version, labels, manual, accessories and pack-out
Quality control	Inspection plan, defect classes and release rule

Approval sequence

Receive and identify the sample before testing or modification.
Record deviations from the requested configuration.
Complete functional, performance and documentation review.
Resolve or formally list every open item.
Sign the approval record and seal a retained reference sample.
Reference the approved record in the purchase order and inspection plan.

Change-control rule

Define which changes require notice, evidence review, a new sample or full reapproval. Component availability does not by itself authorize substitution. Final production conformity must be checked against the controlled records, not memory or appearance alone.

Approval ownership

Name the buyer and supplier representatives authorized to sign, the decision date and any open condition. Distribute the controlled record to purchasing, engineering, quality and packaging teams so every release decision uses the same revision.
