ActiveReinforcements - Test method for yarns - Part 1: Determination of linear density
增强材料 纱线试验方法 第1部分：线密度的测定
Application Summary AI generated
This standard specifies the test method for determining the linear density (mass per unit length) of reinforcement yarns, such as glass, carbon, and aramid fibers. It is applied in the textile and composite materials industries for quality control during yarn production and for verifying raw material specifications before use in woven fabrics or structural composites. The method ensures consistent measurement under standardized conditioning and tension, critical for downstream processing and final product performance.
