Thermoplastics pipes for the transport of fluids - Determination of pendulum impact strength by the Charpy method - Part 2: Test conditions for pipes of various materials
This part of IS0 9854 specifies the values or options chosen for the test parameters, i.e. the impact energy, test piece dimensions, shape and spacing of the test piece supports, and type of test piece, for testing the impact resistance (pendulum method) of thermoplastics pipes of the following materials, when tested in accordance with IS0 9854-l. It applies to pipes made of unplasticized poly(vinyl chloride) (PVC-U), unplasticized poly(vinyl chloride), for extrusion, impact modified (PVC-U,EP), chlorinated poly(vinyl chloride) (PVC-C), acrylonitrile/butadiene/ styrene (ABS), acrylonitrile/styrene/acrylate (ASA) and polypropylene (PP) and propylene-copolymer. This test is not intended to be a reference test method for determining the impact strength of pipes.
