GB/T 33837-2017Coated glass fiber products—Determination of the tension-tension fatigue properties (English PDF)

Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009.

1 Scope

This Standard specifies the method for determination of the tension-tension fatigue properties of the coated glass fiber products.

This Standard is applicable to the products with glass fiber as the base materials, and coated with polyvinyl chloride, polyurethane, fluorine resin, chloroprene rubber or chlorosulfonated polyethylene rubber.

GB/T 7689.5 Reinforcements - Test Method for Woven Fabrics - Part 5: Determination of Tensile Breaking Force and Elongation at Break for Glass Fiber

3 Principle

Cut the coated glass fiber product into strip-shaped specimen along the warp or weft; perform certain cycle of cyclic tensile test; then determine the tensile properties of the specimen; and measure its residual tensile breaking strength and elongation at break.

This Standard specifies two different types of specimens. Specimen A is the products with glass fiber as the base material, and coated with polytetrafluoroethylene, perfluoroalkoxy copolymer, or fluorinated ethylene propylene copolymer; Specimen B is the products with glass fiber as the base material, and coated with polyvinyl chloride, polyurethane, fluorine resin (excluding polytetrafluoroethylene, perfluoroalkoxy copolymer, and fluorinated ethylene propylene copolymer), chloroprene rubber, or chlorosulfonated polyethylene rubber.
