What does it mean?
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.
What value should be specified?
Start from grade 4 to 5 target and adjust for the end use of the garment. 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.
