地下排水和污水用塑料管路系统.未增塑聚氯乙烯(PVC-U)，聚丙烯(PP),带有矿物改性剂的聚丙烯(PP-MD)和聚乙烯(PE).交通区检查孔和检查井规范

[中文适用范围]： 本国际标准化组织标准规定了埋地检查井和检修井（圆形或非圆形）的定义和要求，最大深度为从地面到主井底部 6 米，采用未增塑聚氯乙烯 (PVC-U)、聚丙烯 (PP)、含矿物改性剂的聚丙烯 (PP-MD) 或聚乙烯 (PE) 制造。这些产品用于符合 EN 476 一般要求的交通区域和地下安装区域（应用区域代码“U”），因此标记有“U”。本标准仅适用于制造商在文档中明确说明如何将组件组装成完整检查井或检修井的项目。涵盖的检查井包括：通过检查和清洁设备提供进入排水或污水系统访问的检查井； designated 为检修井（人孔）提供人员进入排水或污水系统访问的井。检查井或检修井可通过各种方法制造，例如注塑、旋转成型、低压成型或根据其他国际标准制造的组件组装而成。组件连接可通过以下方式实现：弹性密封圈接头；PVC-U 的粘合接头；PVC-U、PP 和 PE 的焊接接头；挤出焊接；机械连接。 [外文原描述]： ISO 13272:2011 specifies the definitions and requirements for buried manholes and inspection chambers (circular or non-circular) installed to a maximum depth of 6 m from ground level to the invert of the main chamber and manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifiers (PP-MD) or polyethylene (PE). These products are intended for use in traffic areas and underground installations conforming to the general requirements given in EN 476 and are used outside the building structure (application area code "U"). They are therefore marked accordingly with a "U". ISO 13272:2011 is only applicable to those chamber/manhole items where the manufacturer has clearly stated in the documentation how the components shall be assembled to create a complete manhole or inspection chamber. The inspection chambers covered by ISO 13272:2011 comprise the following: inspection chambers providing access to the drainage or sewerage system by means of inspection and cleaning equipment; chambers designated as manholes providing man access to the drainage or sewerage system.
