Machine Gauge (E) Test Methods and Acceptable Limits
Machine Gauge (E) is verified through machine specification. Knowing how the method works avoids rejecting fabric that actually meets the requirement.
Method overview
machine specification defines sample size, conditioning and calculation, so values are comparable only within the same revision. Working figures for Machine Gauge (E) normally sit around 14G to 40G for circular knitting in mainstream production. Note machine specification on the tech pack so nobody tests against an older revision.
Result interpretation
Read the value together with construction notes; 14G to 40G for circular knitting is only meaningful for similar fabrics. Record elastane content alongside Machine Gauge (E), because blends shift the measured value. A result outside 14G to 40G for circular knitting usually points to process drift rather than to the fibre itself.
Typical limits
Buyers commonly write 14G to 40G for circular knitting with a stated tolerance, then verify against machine specification. Keeping reference values for Machine Gauge (E) lets suppliers quote without extra sampling rounds. Ask for conditioning details together with machine specification, since both affect the reading.
Sources of variation
Conditioning time, operator technique and shade all influence the result. Working figures for Machine Gauge (E) normally sit around 14G to 40G for circular knitting in mainstream production. Note machine specification on the tech pack so nobody tests against an older revision.
Documentation
Record the standard revision on every report, because older versions can differ from current practice. Record elastane content alongside Machine Gauge (E), because blends shift the measured value. A result outside 14G to 40G for circular knitting usually points to process drift rather than to the fibre itself.
