injection moulded PVC socket fittings with solvent cement joints for water supplies: Part 4 Specific requirements for 90 degree tees

This document specifies the technical requirements for injection-moulded polyvinyl chloride socket fittings equipped with solvent-type bonded joints, designed for water supply systems. The focus is specifically on 90-degree tee fittings, detailing the dimensional tolerances, material properties, and performance criteria necessary to ensure reliability in piping networks. It outlines the manufacturing processes, quality control measures, and testing methods that manufacturers must adhere to for producing these components. The standard addresses the mechanical strength, pressure resistance, and compatibility of the fittings with associated pipes and other components within the system. It also covers marking requirements, packaging guidelines, and storage conditions to maintain the integrity of the products throughout their lifecycle. By establishing these uniform technical specifications, the document aims to facilitate consistent quality across different production facilities and ensure the safety and efficiency of water distribution infrastructure. The guidelines provide a comprehensive framework for designers, producers, and inspectors involved in the supply chain of PVC plumbing components.
