Drawing against physical sample
Measure critical dimensions and record any approved deviations. Do not let a visual approval hide an unresolved structural or dimensional issue.
A sample is useful only when it becomes a controlled production reference. Approval should cover the product, packing and the points that will be inspected later.
Use these points as a working brief. The list is deliberately practical: it separates buyer decisions from facts that must be confirmed on drawing, sample or market documentation.
Measure critical dimensions and record any approved deviations. Do not let a visual approval hide an unresolved structural or dimensional issue.
Record the substrate, metal parts, finish reference, hardware and visible colour result. Photographs alone do not replace a retained physical standard.
Test the intended movement, access and load condition without turning an unverified estimate into a public specification. Any commercial load claim needs a defined test basis.
Approve carton, protection, hardware bag and instructions together with the product. A perfect sample can still create complaints if the first packed unit is not checked.
List every change by item, date and owner. Production should refer to one approved revision, not a mixture of chat messages and old drawings.
Agree the critical, major and minor defects, sampling level and who may inspect. Include labels and packing in the inspection scope.
Decide where the approved reference sample stays and how it is protected. Both buyer and supplier should know which unit is authoritative.
If the answer depends on your product, destination or sales channel, include that context in the enquiry.
Not always, but it is the clearest way to freeze a new construction, finish or packing method before volume production.
A signed or otherwise formally recorded approval is useful. Attach the approved drawing, photos and revision list so the decision is traceable.
Inspection access can be planned, but the buyer should confirm the agency, scope, booking responsibility and acceptance criteria before production.
Send the product category, target size, material preference, expected quantity and destination. If a drawing is not ready, send the application and a reference image so the missing decisions can be identified before sampling.
