工业用塑料管道系统. 聚丁烯(PB), 聚乙烯(PE), 耐热聚乙烯(PE-RT), 交联聚乙烯(PE-X), 聚丙烯(PP). 组件和系统的公制系列规范

[中文适用范围]： 本国际标准规定了用于工业应用的塑料管道系统及其组件（包括管道、管件和阀门）的特性与要求，这些组件由以下材料之一制成：聚丁烯 (PB)、聚乙烯 (PE)、耐热聚乙烯 (PE-RT)、交联聚乙烯 (PE-X) 和聚丙烯 (PP)。该标准适用于地下和地上的工业应用，用于输送液体、气体流体以及流体中的固体物质。 [外文原描述]： 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.
