Scope
Scope: This document specifies the terms and definitions, models and categories, requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for polyethylene woven tarpaulins (hereinafter referred to as tarpaulins). This document applies to tarpaulins made from high-density polyethylene as the main raw material, which are extruded and stretched to form flat filaments, woven into base fabrics, and then laminated with low-density polyethylene to form polyethylene composite woven fabrics, which are thermally bonded to produce tarpaulins primarily used for covering purposes. Main technical contents: 5.1 The appearance shall comply with the requirements of Table 2. 5.2 The dimensions and deviations shall comply with the requirements of Table 3. 5.3 The mass per unit area and deviations shall have a tolerance of ±6%. 5.4 The physical and mechanical properties shall comply with the provisions of Table 4. 5.5 The aging performance: For Class I tarpaulins, the retention rate of the tensile load in the longitudinal direction after 500 hours of accelerated aging shall be not less than 70%; for Class II tarpaulins, no requirements are specified. Special requirements shall be implemented in accordance with the contract between the supplier and the buyer.
