Scope

Scope: This document specifies the marking, requirements, test methods, inspection rules, and labeling of basalt fiber reinforced polyethylene MAS composite pipes (hereinafter referred to as "pipes"), as well as their transportation and storage. The basalt fiber reinforced polyethylene MAS composite pipes specified in this document are applicable to water supply engineering pipes. Main Technical Content: (1) Terms and Definitions: Considering the general industry terminology and the materials and related terms involved in this document, this section defines terms such as basalt fiber, antibacterial materials, polyethylene compounding materials, basalt fiber reinforced polyethylene MAS composite pipes, long-term hydrostatic strength, lower confidence limit of predicted hydrostatic strength, minimum required strength, recycled materials, nominal outer diameter, average outer diameter, ovality, nominal wall thickness, nominal pressure, wall thickness tolerance, and hoop stress. (2) Main Raw Materials: 1. Basalt Fiber: Specifies the standard for the basalt fiber used in pipe production, as well as the main physical property requirements and test methods. 2. Polyethylene (PE) Resin: Specifies the main physical property requirements, test methods, and standards for polyethylene (PE) resin based on the requirements of materials and products. 3. Antibacterial Materials: Specifies the standard for the antibacterial materials used in pipe production based on their antibacterial rate. 4. Recycled Materials: To reduce carbon emissions and improve carbon cycle efficiency, while ensuring stable product quality, this document sets a maximum allowable proportion of clean recycled materials used in the production of the same type of pipes within the enterprise. (3) Classification and Marking Standards: The working group reviewed the standards referenced by pipes, including their use, nominal outer diameter × wall thickness, nominal pressure, and corresponding product
