Dimensional Stability How to Read It on a Lab Report
Laboratory reports present Dimensional Stability in a compact format. Knowing what each line means prevents misreading.
Definition reminder
size change after washing. Working figures for Dimensional Stability normally sit around under 3% length, 4% width in mainstream production. Note AATCC 135 home laundering on the tech pack so nobody tests against an older revision.
Common report layout
The report states method AATCC 135 home laundering, sample description, conditioning, and the measured result. Record elastane content alongside Dimensional Stability, because blends shift the measured value. A result outside under 3% length, 4% width usually points to process drift rather than to the fibre itself.

Typical result
Values near under 3% length, 4% width usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Dimensional Stability lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 135 home laundering, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Dimensional Stability normally sit around under 3% length, 4% width in mainstream production. Note AATCC 135 home laundering 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 Dimensional Stability, because blends shift the measured value. A result outside under 3% length, 4% width usually points to process drift rather than to the fibre itself.
