本国际标准规定了用于隔离和控制服务的热塑性材料制成的截止阀的设计、功能特性和制造要求，以及截止阀与管道系统的连接、阀体材料及其在-40°C和+120°C之间的压力/温度额定值，使用寿命为25年，并规定了其试验。 本国际标准适用于安装在工业管道系统中的手动或电动阀门，不考虑应用领域和输送的流体。交叉引用: 2009年12 12 12:12 12 12 12:12 12 12 12 12:12 12 12 12 12:12 12 12 12 12 12:12 12 12 12 12:12 12 12 12 12:12 12 12 12 12:12 12 12 12 12:12 12 12 12 12 12 12:12 12 12 12 12 12 12 12:12 12 12 12 12 12 12 12 12 12:12 12 12 12 12 12 12 12:12 12 12 12 12 12 12 12:12 12 12 12 12 12 12 12 12 12:12 12 12 12 12 12 12 12 12 12:12 12 12 12:12 12 12 12 12 12:12:12 12 12 12 12 12 12 12 12 12:12:12:12:12 12:12:12:12 12 12 12 12:12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12:12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 2019年9月2日

This International Standard specifies requirements for the design, functional characteristics and manufacture of globe valves made of thermoplastics materials intended for isolating and control service, their connection to the pipe system, the body materials and their pressure/temperature rating between – 40 °C and + 120 °C, for a lifetime of 25 years, and also specifies their tests. This International Standard is applicable to hand- or power-operated valves to be installed in industrial pipe systems, irrespective of the field of application and the fluids to be conveyed.Cross References:EN 1092-1:2018EN 12266-1:2012ISO 12162:2009ISO 15493:2003/COR 1:2004ISO 1167-1:2006ISO 15493:2003/AMD 1:2016EN 1267:2012ISO 898-1:2013EN 558:2017ISO 15494:2015EN 736-3:2008ISO 7-1:1994/Cor 1:2007ISO 10931:2005/AMD 1:2015ISO 5210:2017EN 736-1:1995EN 736-2:1997Incorporates the following:Amendment, September 2019
