标准范围

ISO/TR 4191:2014给出了在压力下输送水的管道系统中使用未增塑聚氯乙烯（PVC-U）和定向未增塑聚氯乙烯（PVC-O）管道、配件、阀门和辅助设备的安装推荐规程。这些建议旨在为管道系统的设计和安装提供实际指导，管道系统包括PVC材料制成的管道、配件、阀门和辅助设备，用于以下目的:地下水管和服务设施、承压废水，以及建筑物内外的地上输水，用于在约20°C（冷水）的压力下供应供人类饮用和一般用途的水。ISO/TR 4191:2014也适用于输送45°C及以下水的部件。对于25°C至45°C之间的温度，ISO 1452？2:2009图1适用。此外，还提供了连接配件、阀门和辅助设备（由PVC以外的材料制成）的建议。

ISO/TR 4191:2014 gives recommended practices for installation of unplasticized poly(vinyl chloride) (PVC-U) and oriented unplasticized poly(vinyl chloride) (PVC-O) pipes, fittings, valves, and ancillaries when used in piping systems conveying water under pressure.The recommendations are intended to give practical guidance of design and installation of piping systems incorporating pipes, fittings, valves, and ancillary equipment made from PVC materials and used for the following purposes: water mains and services buried in ground, waste water under pressure, and conveyance of water above ground for both outside and inside buildings, for the supply of water under pressure at approximately 20 °C (cold water) intended for human consumption and for general purposes.ISO/TR 4191:2014 is also applicable to components for the conveyance of water up to and including 45 °C. For temperatures between 25 °C and 45 °C, Figure 1 of ISO 1452？2:2009 applies.In addition, recommendations are given for the connection to fittings, valves, and ancillary equipment made from materials other than PVC.
