Colour Fastness to Chlorinated Water Why Shipments Get Rejected Over This
Many disputes come down to Colour Fastness to Chlorinated Water. Below is what inspectors check and why shipments fail.
The core definition
stability in pool water. Working figures for Colour Fastness to Chlorinated Water normally sit around grade 4 at 1 ppm chlorine in mainstream production. Note ISO 105-E03 chlorinated water on the tech pack so nobody tests against an older revision.
Most common cause of failure
Results usually fall outside grade 4 at 1 ppm chlorine because the target was never written into the order. Record elastane content alongside Colour Fastness to Chlorinated Water, because blends shift the measured value. A result outside grade 4 at 1 ppm chlorine usually points to process drift rather than to the fibre itself.

How it is checked
Inspection and laboratory work both refer to ISO 105-E03 chlorinated water. Keeping reference values for Colour Fastness to Chlorinated Water lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 105-E03 chlorinated water, since both affect the reading.
Related faults
it is mandatory for swimwear, so related complaints often point back to this single parameter. Working figures for Colour Fastness to Chlorinated Water normally sit around grade 4 at 1 ppm chlorine in mainstream production. Note ISO 105-E03 chlorinated water on the tech pack so nobody tests against an older revision.
Avoiding rejection
Agree targets, tolerances and the method before production, then test per lot rather than per shipment. Record elastane content alongside Colour Fastness to Chlorinated Water, because blends shift the measured value. A result outside grade 4 at 1 ppm chlorine usually points to process drift rather than to the fibre itself.
