<p>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:</p>
<p>- polypropylene homopolymer (PP-H);</p>
<p>- polypropylene block copolymer (PP-B) (also called heterophasic copolymer);</p>
<p>- polypropylene random copolymer (PP-R);</p>
<p>- 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).</p>
