ISO 13272:2011规定了埋地检修孔和检查室（圆形或非圆形）的定义和要求，安装在从地面到主室倒置的最大深度为6 m，由未增塑的聚氯乙烯（PVC-U）、聚丙烯（PP）、含矿物改性剂的聚丙烯（PP-MD）或聚乙烯（PE）制成。这些产品旨在用于符合EN 476给出的一般要求的交通区域和地下设施，并在建筑结构外部使用（应用区域代码“U”）。因此，它们相应地用“U”标记。 ISO 13272:2011仅适用于制造商在文件中明确说明组件应如何组装以形成完整的人孔或检查室的那些室/人孔项目。ISO 13272:2011涵盖的检查室包括以下内容: 通过检查和清洁设备提供通往排水或污水系统的通道的检查室； 指定为人孔的房间，为人提供通往排水或污水系统的通道。

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.
