Introduction
This part of ISO 6259 specifies a method for determining the tensile properties of pipes made of PVC-U,
PVC-O, PVC-C and PVC-HI.
NOTE In some countries PVC-HI is designated as PVC-M or PVC-A
It can provide data for further testing for the purpose of research and development.
It cannot be regarded as significant for applications in which the conditions of application of the force
differ considerably with those in this test method, such applications requiring the appropriate impact,
creep and fatigue tests.
The tests of tensile properties are intended to be principall
