ISO 15494:2015规定了由以下材料之一制成的部件（如管道、配件和阀门）的特性和要求，这些材料拟用于地上和地下工业应用领域的热塑性塑料管道系统: -聚丁烯； -聚乙烯； -耐高温聚乙烯（PE-RT）； -交联聚乙烯（PE-X）； -聚丙烯（PP）。 注1:本国际标准和/或其他标准中给出了工业阀门的要求。阀门应与符合本国际标准的部件一起使用，前提是它们还符合本国际标准的相关要求。 本国际标准适用于PB、PE、PE-RT、PE-X或PP管道、配件、阀门及其接头，以及与其他塑料和非塑料材料部件的接头，具体取决于其适用性，用于输送工业应用中的液体、气体流体以及流体中的固体物质，如: -化工厂； -工业污水工程； -电力工程（冷却水和通用水）； -采矿业； -电镀和酸洗厂； -半导体工业； -农业生产工厂； -消防； -水处理； -地热。 注2:相关国家法规（如适用）。 g、 水处理）适用。 如果满足本国际标准和/或适用国家要求，则允许其他应用领域。 有关火灾行为和爆炸风险的国家法规适用。 部件必须能够承受预期的机械、热和化学要求，并且必须能够抵抗输送的流体。

ISO 15494:2015 specifies the characteristics and requirements for components such as pipes, fittings, and valves made from one of the following materials intended to be used for thermoplastics piping systems in the field of industrial applications above and below ground: - polybutene (PB); - polyethylene (PE); - polyethylene of raised temperature resistance (PE-RT); - crosslinked polyethylene (PE-X); - polypropylene (PP). NOTE 1 Requirements for industrial valves are given in this International Standard and/or in other standards. Valves are to be used with components conforming to this International Standard provided that they conform additionally to the relevant requirements of this International Standard. This International Standard is applicable to either PB, PE, PE-RT, PE-X, or PP pipes, fittings, valves, and their joints and to joints with components of other plastics and non-plastic materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as solid matter in fluids for industrial applications such as the following: - chemical plants; - industrial sewerage engineering; - power engineering (cooling and general purpose water); - mining; - electroplating and pickling plants; - semiconductor industry; - agricultural production plants; - fire fighting; - water treatment; - geothermal. NOTE 2 Where relevant, national regulations (e.g. water treatment) are applicable. Other application areas are permitted if the requirements of this International Standard and/or applicable national requirements are fulfilled. National regulations in respect of fire behaviour and explosion risk are applicable. The components have to withstand the mechanical, thermal, and chemical demands to be expected and have to be resistant to the fluids to be conveyed.
