Committee: Plastic Pipes and Fittings
Sector: Mechanical and Metals
Project Method: Adoption with modification
Project Type: New
International Classification for Standards (ICS)

23.040.20 Plastics pipes
Adopted Standard
Standards / Amendment / Corrigendum
1 ISO 3213:2009
Scope
This International Standard 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 copolymer1) (PP-B);
— polypropylene random copolymer (PP-R);
— polypropylene random copolymer2) with a modified crystallinity (PP-RCT).
