标准范围

ISO 15876-3:2017规定了用于建筑物内冷水和热水输送装置的聚丁烯-1（PB-1）管道系统配件的特性，无论是否用于人类消费（家用系统）以及根据应用类别在设计压力和温度下的加热系统（见ISO 15876-1）。在本文件中，名称聚丁烯与缩写PB一起使用。ISO 15876-3:2017涵盖了一系列工作条件（应用等级）和设计压力等级。对于超过ISO 15876-1:2016表1规定的TD、Tmax和Tmal值，本文件不适用。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到的试验方法的参数。与ISO 15876的其他部分一起，本文件适用于PB制成的配件和其他材料制成的配件，这些配件拟安装在符合ISO 15876-2的热水和冷水安装管道上，因此接头符合ISO 15876-5的要求。ISO 15876-3:2017适用于以下类型的配件:-套筒熔合配件；-电熔配件；-机械配件；-带有嵌入件的配件。它也适用于由替代材料制成的配件，这些配件安装在符合ISO 15876？2的管道上时，符合ISO 15876？5的要求。

ISO 15876-3:2017 specifies the characteristics of fittings for 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 ISO 15876？1).The designation polybutene is used together with the abbreviation PB throughout this document.ISO 15876-3:2017 covers a range of service conditions (application classes) and design pressure classes. For values of TD, Tmax and Tmal in excess of those in ISO 15876？1:2016, Table 1, this document does 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 parameters for the test methods referred to in this document.In conjunction with the other parts of ISO 15876, this document is applicable to fittings made from PB and to fittings made from other materials which are intended to be fitted to pipes conforming to ISO 15876？2 for hot and cold water installations, whereby the joints conform to the requirements of ISO 15876？5.ISO 15876-3:2017 is applicable to fittings of the following types:- socket fusion fittings;- electrofusion fittings;- mechanical fittings;- fittings with incorporated inserts.It is also applicable to fittings made from alternative materials which, when fitted to pipes conforming to ISO 15876？2, conform to the requirements of ISO 15876？5.
