Ponte Roma Test Methods and Acceptable Limits
Ponte Roma is verified through double knit machine. Knowing how the method works avoids rejecting fabric that actually meets the requirement.
Method overview
double knit machine defines sample size, conditioning and calculation, so values are comparable only within the same revision. Working figures for Ponte Roma normally sit around 250-320 GSM in mainstream production. Note double knit machine on the tech pack so nobody tests against an older revision.
Result interpretation
Read the value together with construction notes; 250-320 GSM is only meaningful for similar fabrics. Record elastane content alongside Ponte Roma, because blends shift the measured value. A result outside 250-320 GSM usually points to process drift rather than to the fibre itself.
Typical limits
Buyers commonly write 250-320 GSM with a stated tolerance, then verify against double knit machine. Keeping reference values for Ponte Roma lets suppliers quote without extra sampling rounds. Ask for conditioning details together with double knit machine, since both affect the reading.
Sources of variation
Conditioning time, operator technique and shade all influence the result. Working figures for Ponte Roma normally sit around 250-320 GSM in mainstream production. Note double knit machine 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 Ponte Roma, because blends shift the measured value. A result outside 250-320 GSM usually points to process drift rather than to the fibre itself.
