OEKO-TEX Standard 100 Setting It Correctly on a Tech Pack
OEKO-TEX Standard 100 should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
certification that tested articles are harmless. Working figures for OEKO-TEX Standard 100 normally sit around four product classes in mainstream production. Note annual laboratory testing and audit on the tech pack so nobody tests against an older revision.
Target value
Open the specification at four product classes, adjusted to the end use. Record elastane content alongside OEKO-TEX Standard 100, because blends shift the measured value. A result outside four product classes usually points to process drift rather than to the fibre itself.

Method line
Always pair the target with annual laboratory testing and audit so the mill and the laboratory test the same way. Keeping reference values for OEKO-TEX Standard 100 lets suppliers quote without extra sampling rounds. Ask for conditioning details together with annual laboratory testing and audit, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for OEKO-TEX Standard 100 normally sit around four product classes in mainstream production. Note annual laboratory testing and audit 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 OEKO-TEX Standard 100, because blends shift the measured value. A result outside four product classes usually points to process drift rather than to the fibre itself.
