A production sample is a unit taken from or made using the intended mass-production materials, tooling and process for evaluation. It helps confirm that the factory can reproduce the approved requirements under production conditions.
When is a production sample used?
It may be reviewed before full production, during an initial production run or as part of ongoing quality control. The timing and selection method should be documented.
Production sample vs. prototype
A prototype tests a concept and may use temporary methods or materials. A production sample should represent the actual process and inputs intended for saleable units.
What should be checked?
- Dimensions, materials and workmanship
- Function and performance
- Color, finish and branding
- Packaging and labeling
- Regulatory and safety requirements
- Consistency with the approved specification
Does approval guarantee the whole batch?
No. One sample cannot prove every unit conforms. Batch inspection, process controls and testing remain necessary according to the risk and quality plan.
How should approval be recorded?
Identify the sample, specification version, factory, date, results, deviations and authorized decision. Retain physical or photographic evidence under controlled conditions.
