Splices: The coated belt or band shall be joined to form a smooth, continuous, non-separating surface. Cloth backing material: The treated cloth backing material shall be in accordance with Table 1 and tested in accordance with ASTM D 5035. When waterproof material is specified, the backing material shall be treated to make it impervious to water. TABLE I COATED CLOTH BACKING AVERAGE BREAKING STRENGTH TYPE BACKING WEIGHT WARP DIRECTION FILLING DIRECTION (lbs per square inch minimum) “J” weight Jeans cloth 100 lbs/in 45 lbs/in “X” weight Drills cloth 130 lbs/in 50 lbs/in “Y” weight Heavy drills cloth 160 lbs/in 65 lbs/in NOTE: Tolerance plus or minus 15% Identification: The belts shall be identified by the size, manufacturer’s name or trademark, type of abrasive, grit size, backing weight, type coating and directional arrow. Test for breaking strength: Minimum average breaking strength shall be determined in accordance with the cut-strip method of ASTM D 5035, "STANDARD TEST METHODS FOR BREAKING FORCE AND ELONGATION OF TEXTILE FABRICS", using 1 inch strips of the coated abrasive product. Samples shall be tested immediately after being conditioned for 24 consecutive hours at 70 + or - 2 degrees F, and 50 + or - 2% relative humidity. Failure of the sample strips to conform with stated minimum average requirements shall be cause for rejection of the entire lot. Workmanship: The grain shall be evenly dispersed and positively bonded throughout the open or closed coated type belt as specified. The belt shall be designed to preclude disintegration of the grain from the backing material. The backing material shall be designed to prevent separation of the belt under normal conditions and designed usage. Belts shall be suitable for use under the guidelines described in ANSI B7.7.
