Tensile Strength How to Read It on a Lab Report
Laboratory reports present Tensile Strength in a compact format. Knowing what each line means prevents misreading.
Definition reminder
maximum force before breaking. Working figures for Tensile Strength normally sit around above 150 N for most knits in mainstream production. Note ISO 13934-1 strip test on the tech pack so nobody tests against an older revision.
Common report layout
The report states method ISO 13934-1 strip test, sample description, conditioning, and the measured result. Record elastane content alongside Tensile Strength, because blends shift the measured value. A result outside above 150 N for most knits usually points to process drift rather than to the fibre itself.
Typical result
Values near above 150 N for most knits usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Tensile Strength lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13934-1 strip test, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Tensile Strength normally sit around above 150 N for most knits in mainstream production. Note ISO 13934-1 strip 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. Record elastane content alongside Tensile Strength, because blends shift the measured value. A result outside above 150 N for most knits usually points to process drift rather than to the fibre itself.
