This part of GB/T 8804 specifies the test for tensile properties of rigid polyvinyl chloride (PVC-U), chlorinated polyvinyl chloride (PVC-C) and high-impact polyvinyl chloride (PVC-HI) thermoplastic pipes method, in particular the following properties: - tensile yield stress; - elongation at break. This part applies to rigid polyvinyl chloride (PVC-U), chlorinated polyvinyl chloride (PVC-C) and high-impact polyvinyl chloride (PVC-HI) pipes for various purposes. Note: See GB/T 8804.1 for general principles of tensile test methods for tensile properties of thermoplastic pipes.
