Industry quality standards require materials to be tested at the manufacturer and the results of these tests be submitted through a report, also called a Mill Sheet, Mill Certificate or Mill Test Certificate (MTC).
Example-Higher Temperature and Reduced Strength. If operating pressure for a 6 Schedule 80 CPVC pipe is 167 psi, the maximum operating pressure at 150 oF (66 oC) is reduced to.(167 psi) 0.5. = 83.5 psi. Temperature Derating of Steel Pipes-Temperature derating factor of steel pipes. 2  Plastic Pipes and Operating Temperatures-ABS, PE, PVC, CPVC, PB, PP and SR-Operating temperatures with or without pressure. 3  PVC Pipes-Pressure Ratings-Maximum operating and required burst pressure of PVC-Polyvinyl Chloride-pipe fittings.
