PEX conforms to which standard?

ASTM
ASME
ANSI
ISO

The correct answer is: ASME

PEX, or cross-linked polyethylene, conforms to the ASTM (American Society for Testing and Materials) standards, specifically ASTM F876 and F877. These standards are essential for establishing the specifications, requirements, and testing methods related to PEX tubing and system components. ASTM standards are widely recognized for ensuring the quality and safety of materials used in plumbing and heating applications. Conversely, ASME (American Society of Mechanical Engineers) focuses on mechanical engineering standards, ANSI (American National Standards Institute) oversees the development of voluntary consensus standards, and ISO (International Organization for Standardization) develops international standards across various fields. While ASME, ANSI, and ISO have important roles in standardization, the specific standards relevant to PEX are established by ASTM. Therefore, those familiar with PEX should prioritize the ASTM standards to ensure proper material selection and compliance in their installations.
