What standard do plastic pipes and PVC in hydronic systems adhere to?

Plastic pipes and PVC used in hydronic systems adhere to ASTM standards, which stands for the American Society for Testing and Materials. ASTM provides a framework that specifies the minimum requirements for materials, including dimensions, performance, and safety in various applications.

In the context of hydronic systems, these standards ensure that the plastic pipes can withstand the pressure and temperature conditions they will encounter while effectively transferring heat through the system. Compliance with ASTM standards means that the materials have been tested and verified for durability, strength, and suitability for specific applications, thus ensuring reliability and safety in hydronic heating or cooling systems.

While other organizations also set standards, ASTM is especially relevant for the materials used in plumbing and hydronic applications in the United States.
