高压埋地污废水排放用塑料管道系统.聚乙烯管材(PE

[中文适用范围]： 本国际标准规定了用于非压力地下排水和污水处理、输送家庭和工业来源的土壤和废物排放以及地表水的聚乙烯（PE）管道、配件和管道系统的要求。 它涵盖埋地管道以及埋在建筑结构内的管道系统。 在工业排放的情况下，需要考虑耐化学性和耐温性，但这需要单独进行。 本国际标准适用于带或不带整体承插口的聚乙烯管道。 注：管件可以通过注射成型或由管道和/或模制品制造。 本国际标准适用于以下类型接头的聚乙烯管道和管件： ——弹性环密封接头； ——对接熔接接头； ——电熔接头； ——机械接头。 本国际标准还规定了本文提及的测试方法的测试参数。 [外文原描述]： ISO 8772:2006 specifies the requirements for polyethylene (PE) pipes, fittings and piping systems intended for use for non-pressure underground drainage and sewerage for the conveyance of soil and waste discharge of domestic and industrial origin, as well as surface water. It covers buried pipework, as well as piping systems buried within the building structure. In the case of industrial discharge, it is necessary that the chemical and temperature resistance be taken into account, but this will need to be done separately. ISO 8772:2006 is applicable to PE pipes with or without an integral socket. This International Standard is applicable to PE pipes and fittings for the following types of joints: elastomeric ring seal joints; butt fused joints; electrofusion joints; mechanical joints. ISO 8772:2006 also specifies the test parameters for the test methods referred to therein.
