Decision of the Institute of Standardization of Moldova No. 95 dated 19.04.2018

This technical specification establishes the essential requirements and test methods for rigid polypropylene pipes and fittings designed for the transport of hot water in plumbing and heating systems. It defines the classification, dimensional tolerances, and physical properties necessary to ensure safety and performance under high-temperature conditions. The document aligns with harmonized European standards to facilitate international trade and technical compatibility. It covers materials used in the manufacturing process, detailing the specific grades and additives required for long-term durability. Testing procedures address pressure resistance, thermal stability, and chemical resistance to maintain system integrity over extended periods. The text provides guidance on installation practices to prevent failure due to thermal expansion or improper jointing. Compliance with these specifications ensures that the products meet rigorous quality benchmarks for domestic and industrial water supply applications. It serves as a reference for manufacturers, regulators, and contractors to verify that piping systems operate safely within their intended pressure and temperature ranges. The guidelines also address packaging and labeling requirements to assist in product identification and traceability throughout the supply chain.
