Surface repellency describes water beading, while a waterproof garment claim depends on fabric resistance, seams, closures and a defined exposure test.
Frame the decision
Name the use scenario and separate finish, material and garment construction requirements before selecting test methods and acceptance evidence.
Marketing and RFQ language should reflect the verified system level and avoid converting one material result into a garment promise.
Build the controlled worksheet
Keep these five topic-specific inputs together so the quotation, sample and inspection teams do not work from different assumptions:
- Rain exposure and duration: state the requirement, reference, status and approval owner.
- Fabric test method: state the requirement, reference, status and approval owner.
- Seam sealing: state the requirement, reference, status and approval owner.
- Closure construction: state the requirement, reference, status and approval owner.
- Breathability and care trade-offs: state the requirement, reference, status and approval owner.
Evidence to request
- Approved source or drawing for rain exposure and duration
- Order-specific record covering fabric test method
- Written acceptance basis for seam sealing
- Controlled decision history for closure construction
- Release evidence connected to breathability and care trade-offs
Evidence must identify the relevant product, material, revision or lot. Record any limitation, substitution or item still awaiting approval.
Risks to close before approval
- Calling a DWR-treated softshell waterproof
- Testing fabric while ignoring unsealed seams
- Omitting breathability and care trade-offs from the decision
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.
