This part of ISO 6259 specifies a method of determining the tensile properties of polyolefin (polyethylene, cross-linked polyethylene, polypropylene and polybutene) pipes, and in particular the following properties:
— the stress at yield;
— the elongation at break.
NOTES
1 The properties of butt fusion welds may be assessed by using machined test pieces of the types specified in this document.
2 The general method of test for the determination of the tensile properties of thermoplastics pipes is given in ISO 6259-1.
This part of ISO 6259 also gives, for information purposes only, the corresponding basic specifications in annexes A to D.
