标准范围

ISO 4642-2:2009规定了消防车和拖车泵用半刚性卷盘软管的要求和试验方法。对于正常压力软管（I类），软管的最大工作压力为1.5 MPa；对于高压软管（II类），软管的最大工作压力为4.0 MPa。软管进一步细分为类型和类别。ISO 4642-2:2009适用于最低环境温度为-20°C的消防用输送软管。符合ISO 4642-2:2009的软管应与符合相关国家标准的消防软管接头一起使用。对于软管制造商安装的软管组件，也给出了相关要求。

ISO 4642-2:2009 specifies the requirements and test methods for semi-rigid reel hoses for use on fire fighting vehicles and trailer pumps. The hoses are intended for use at a maximum working pressure of 1,5 MPa for normal pressure hoses (category I) and 4,0 MPa for high pressure hoses (category II). The hoses are further subdivided into types and classes.ISO 4642-2:2009 applies to delivery hoses for fire-fighting purposes intended for use at a minimum ambient temperature of minus 20 °C.Hoses conforming to ISO 4642-2:2009 should be used with fire hose couplings conforming to the relevant national standards couplings.Requirements are also given for hose assemblies where these are fitted by the hose manufacturer.
