无压力地下排水和排污塑料管道系统.聚丙烯(PP

[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的聚丙烯（PP）管道、配件和管道系统的要求，用于输送家庭和工业来源的土壤和废物排放以及地表水。 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丙烯管道，以及通过带密封圈的推入式接头或对接熔接接头进行的连接。 注 1：管件可以通过注射成型或由管道和/或模制品制造。 该国际标准涵盖具有正常 E 模量和较高 E 模量（称为 HM（较高模量））的 PP 材料，并给出了一系列公称尺寸和管道系列以及有关颜色的建议。 本国际标准还规定了本文提及的测试方法的测试参数。 注 2：具有正常 E 模量的 PP 材料的 E 模量在 1 250 MPa 至 1 700 MPa 之间。 较高E模量的PP材料（PP-HM材料）的E模量大于或等于1 700 MPa。 [外文原描述]： ISO 8773:2006 specifies the requirements for polypropylene (PP) 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 8773:2006 is applicable to PP pipes with or without an integral socket and to jointing by means of push fit joints with sealing rings or butt-fused joints. It covers PP materials with normal E moduli and with higher E moduli, designated as HM (higher modulus), and gives a range of nominal sizes and pipe series, as well as recommendations concerning colours. ISO 8773:2006 also specifies the test parameters for the test methods referred to therein.
