Water Repellency Spray Test How to Read It on a Lab Report
Laboratory reports present Water Repellency Spray Test in a compact format. Knowing what each line means prevents misreading.
Definition reminder
how well water beads on the surface. Working figures for Water Repellency Spray Test normally sit around grade 4 to 5 target in mainstream production. Note AATCC 22 spray test on the tech pack so nobody tests against an older revision.
Common report layout
The report states method AATCC 22 spray test, sample description, conditioning, and the measured result. Record elastane content alongside Water Repellency Spray Test, because blends shift the measured value. A result outside grade 4 to 5 target usually points to process drift rather than to the fibre itself.

Typical result
Values near grade 4 to 5 target usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Water Repellency Spray Test lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 22 spray test, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Water Repellency Spray Test normally sit around grade 4 to 5 target in mainstream production. Note AATCC 22 spray test on the tech pack so nobody tests against an older revision.
Questions to ask
Ask the laboratory for the standard revision and sample description before accepting or rejecting a result.
