ISO 15876-1:2017规定了聚丁烯-1（PB-1）管道系统的一般方面，该管道系统拟用于建筑物内的热水和冷水装置，用于输送水，无论是否用于人类消费（家用系统）和供暖系统，其设计压力和温度取决于应用类别（见表1）。 在本文件中，名称聚丁烯与缩写PB一起使用。 ISO 15876-1:2017涵盖了一系列使用条件（应用等级）、设计压力和管道尺寸等级。 超过表1的TD、Tmax和Tmal值不适用。 注:买方或规范方有责任从这些方面做出适当选择，同时考虑其特殊要求和任何相关国家法规和安装实践或规范。 它还规定了本文件中提及的试验方法的试验参数。 本文件与ISO 15876的其他部分一起适用于PB管道、管件及其接头，以及与其他塑料和非金属部件的接头- 用于热水和冷水装置的塑料材料。

ISO 15876-1:2017 specifies the general aspects of polybutene-1 (PB-1) piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water whether or not intended for human consumption (domestic systems) and for heating systems, under design pressures and temperatures according to the class of application (see Table 1). The designation polybutene is used together with the abbreviation PB throughout this document. ISO 15876-1:2017 covers a range of service conditions (application classes) and design pressure and pipe dimension classes. Values of TD, Tmax and Tmal in excess of those in Table 1 do not apply. NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. It also specifies the test parameters for the test methods referred to in this document. In conjunction with the other parts of ISO 15876, this document is applicable to PB pipes, fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations.
