This part of IS0 6259 specifies a method of determining the tensile properties of pipes made of poly(vinyl chloride) (PVC-U), chlorinated poly(vinyl chloride) (PVC-C) and high-impact poly(vinyl chloride) (PVC-HI), and in particular the following properties:
- the stress at yield;
- the elongation at break.
NOTE - The general method of test for the determination of the tensile properties of thermoplastics pipes is given in IS0 6259-i. This part of IS0 6259 also gives, for information purposes only, the corresponding basic specifications in annexes A, B and C.
