31、 Arbor, Michigan 48113-0140, USA. 1 2017 NSF NSF/ANSI 14 2016b NSF/ANSI Standard for Plastics Plastics piping system components and related materials 1 General 1.1 Purpose This Standard establishes minimum physical, performance, and health effects requirements for plastic piping system components an
32、d 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 thermoplastic and thermoset plastic piping system components including, but not limited to, pip
33、es, 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 to manufacture plastic piping system components. This Standard provides definitions an
34、d requirements for materials, ingredients, products, quality assurance, marking, and recordkeeping. Plastic piping system components which are manufactured to one of the normative references in 2 and do not have integral connections specifically intended for plastic piping systems are not covered by
35、 this Standard. 1.3 Materials, design, and construction For plastic piping system components and materials cited by the references in 2, the materials, design, and construction requirements of this Standard and the applicable product standard(s) in 2 shall apply. When materials, designs, or construc
36、tions are utilized that are not cited in 2, the plastic piping system components and related materials shall comply with the applicable requirements of this Standard. Plastic piping system components and related materials that incorporate materials, designs, or constructions not cited in 2 shall be
37、acceptable, provided that such plastic piping system components and related materials can be demonstrated to be at least equivalent in terms of strength, quality, effectiveness, durability, and safety to those that are cited in this Standard. 2 Normative references The following documents contain re
38、quirements that, by reference in this text, constitute requirements of this Standard. At the time of publication, the indicated editions were valid. All of the documents are subject to revision, and parties are encouraged to investigate the possibility of applying the recent editions of the document
