Restricted Substances List (RSL) Setting It Correctly on a Tech Pack
Restricted Substances List (RSL) should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
list of banned or limited chemicals. Working figures for Restricted Substances List (RSL) normally sit around reviewed each season in mainstream production. Note brand-specific published list on the tech pack so nobody tests against an older revision.
Target value
Open the specification at reviewed each season, adjusted to the end use. Record elastane content alongside Restricted Substances List (RSL), because blends shift the measured value. A result outside reviewed each season usually points to process drift rather than to the fibre itself.
Method line
Always pair the target with brand-specific published list so the mill and the laboratory test the same way. Keeping reference values for Restricted Substances List (RSL) lets suppliers quote without extra sampling rounds. Ask for conditioning details together with brand-specific published list, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for Restricted Substances List (RSL) normally sit around reviewed each season in mainstream production. Note brand-specific published list on the tech pack so nobody tests against an older revision.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. Record elastane content alongside Restricted Substances List (RSL), because blends shift the measured value. A result outside reviewed each season usually points to process drift rather than to the fibre itself.
