| Extractable Matter | 9 |
| Fabric Count of Woven Fabrics | 12 |
| Fabric Count of Knitted Fabrics | 13 |
| Length of Woven Fabrics | 11 |
| Mass per Unit Area (Weight) of Woven Fabrics | 14 |
| Shrinkage-Hot Wet Method | 17 |
| Shrinkage-Hot Dry Method | 18 |
| Width of Woven Fabrics | 10 |
1.2 The values stated in SI units are to be regarded as standard. The values in inch-pound units are provided as information only and are not exact equivalents. In case of referee decisions, the SI units will prevail.
