30、 performance, and health effects requirements for plastic piping system components and related materials. These criteria were established for the protection of public health and the environment. 1.2 Scope The physical, performance, and health effects requirements in this Standard apply to thermoplas
31、tic and thermoset plastic piping system components including, but not limited to, pipes, fittings, valves, joining materials, gaskets, and appurtenances. The established physical, performance, and health effects requirements also apply to materials (resin or blended compounds) and ingredients used t
32、o manufacture plastic piping system components. This Standard provides definitions and requirements for materials, ingredients, products, quality assurance, marking, and recordkeeping. Plastic piping system components which are manufactured to one of the normative references in Section 2 and do not
33、have integral connections specifically intended for plastic piping systems are not covered by this Standard. 1.3 Materials, design, and construction For plastic piping system components and materials cited by the references in Section 2, the materials, design, and construction requirements of this S
34、tandard and the applicable product standard(s) in Section 2 shall apply. When materials, designs, or constructions are utilized that are not cited in Section 2, the plastic piping system components and related materials shall comply with the applicable requirements of this Standard. Plastic piping s
35、ystem components and related materials that incorporate materials, designs, or constructions not cited in Section 2 shall be acceptable, provided that such plastic piping system components and related materials can be demonstrated to be at least equivalent in terms of strength, quality, effectivenes
36、s, durability, and safety to those that are cited in this Standard. 2 Normative references The following documents contain requirements that, by reference in this text, constitute requirements of this Standard.
