A colorfastness grade has meaning only with the material, coloration route, exposure, test method, laboratory and acceptance point that produced it.

Subject-matter check required. Verify every numeric threshold, named standard, commercial term and supplier-specific statement for the exact product and contract.

Frame the decision

List the relevant exposure risks for the uniform, name the agreed method, and require a report that identifies the approved fabric or production lot.

The buyer should be able to trace every colorfastness decision to the exact material and order requirement.

Build the controlled worksheet

Keep these five topic-specific inputs together so the quotation, sample and inspection teams do not work from different assumptions:

  • Fiber content and coloration method: state the requirement, reference, status and approval owner.
  • Test method and laboratory: state the requirement, reference, status and approval owner.
  • Exposure type: state the requirement, reference, status and approval owner.
  • Acceptance threshold: state the requirement, reference, status and approval owner.
  • Lot-level evidence: state the requirement, reference, status and approval owner.

Evidence to request

  • Approved source or drawing for fiber content and coloration method
  • Order-specific record covering test method and laboratory
  • Written acceptance basis for exposure type
  • Controlled decision history for acceptance threshold
  • Release evidence connected to lot-level evidence

Evidence must identify the relevant product, material, revision or lot. Record any limitation, substitution or item still awaiting approval.

Risks to close before approval

  • Quoting a grade without a test method
  • Using a generic report for a different fabric or shade
  • Ignoring shade change between approved sample and bulk lot

Assign an owner, due date and written disposition to each unresolved risk. Do not allow an informal answer to replace a controlled revision.

Use the result in the RFQ

Attach the worksheet, quantity, destination, required date and current sample status. Ask the supplier to list assumptions and exceptions against the same five inputs.
