Tear Strength How to Read It on a Lab Report
Laboratory reports present Tear Strength in a compact format. Knowing what each line means prevents misreading.
Definition reminder
force needed to continue a tear. Working figures for Tear Strength normally sit around above 10 N typical in mainstream production. Note ISO 13937-2 trouser tear on the tech pack so nobody tests against an older revision.
Common report layout
The report states method ISO 13937-2 trouser tear, sample description, conditioning, and the measured result. Record elastane content alongside Tear Strength, because blends shift the measured value. A result outside above 10 N typical usually points to process drift rather than to the fibre itself.

Typical result
Values near above 10 N typical usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Tear Strength lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13937-2 trouser tear, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Tear Strength normally sit around above 10 N typical in mainstream production. Note ISO 13937-2 trouser tear 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 Tear Strength, because blends shift the measured value. A result outside above 10 N typical usually points to process drift rather than to the fibre itself.
