Check for compliance with table 1. SANS

49、 1585:2008 Edition 2.1 9 6.10 Water resistance (spray test) Use SANS 5300, on the proofed side of the fabric. Check for compliance with table 1. 6.11 Abrasion resistance Use SANS 6009, but clamp the fabric on the baseplate of the abrasion machine, with the coated side uppermost, and clamp the standard cross-bred worsted abradant fabric in the specimen holder. Abrade the fabric for either 5 000 rubs in the case of types C140 and C245 or 10 000 rubs in the case of type C290, under an applied pressure of 9 kPa. Vi
