Polypropylene (PP) pipes — Effect of time and temperature on the expected strength
|Standard´s number:||ISO 3213|
ISO 3213:2009 specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on pipes made of: - polypropylene homopolymer (PP-H); - polypropylene block copolymer (PP-B) (also called heterophasic copolymer); - polypropylene random copolymer (PP-R); - polypropylene random copolymer (this material can be distinguished by DSC testing or another appropriate method to indicate a second melting peak) with a modified crystallinity (PP-RCT).
