ISO 4437 - HDPE for Natural Gas

ISO 4437 - HDPE for Natural Gas

ISO 4437 - HDPE for Natural Gas

(OP)
Does any one know what specs european valve manufactures (PE100 or PE80) manufacture and test HDPE valves to? I cannot find any reference in ISO 4437.

Can these valves (PE100) be used under the ASTM D2513 specs if they do not comly to ASME B16.40?
