This standard specifies the terms and definitions, classification and marking, raw materials, requirements, test methods, inspection rules, signs, packaging, transportation, storage, factory certificates and technical documents of glass fiber reinforced plastic sand pipes. This standard is applicable to the underground and the For ground water supply and drainage, water conservancy, farmland irrigation and other pipeline projects, the maximum temperature of the medium shall not exceed 50 °C. Glass fiber reinforced plastic pipes without sand inclusions and FRPM pipes whose nominal diameter, pressure level and ring stiffness level are not within the scope of this standard can also be used with reference to this standard.
