BS ISO 4642-2:2015规定了道路用半刚性卷筒软管的要求和试验方法 消防车和拖车泵。软管拟在最大工作压力下使用 正常压力软管（I类）为1.5 MPa，高压软管（II类）为4.0 MPa。这个 软管进一步细分为类型和类别（见第4条）。ISO 4642的本部分适用于最低限度使用的消防用输送软管 环境温度为-20°C。符合ISO 4642本部分要求的软管拟与符合ISO 4642要求的消防软管接头一起使用 符合相关国家标准。还给出了软管组件（见6.12）的要求，其中软管组件由软管安装 制造商注1:在低于-20°C的温度下使用的软管可由双方协商提供 制造商和买方。注2:所有压力均以兆帕表示，其中1兆帕=10巴。交叉引用:ISO 176:2005ISO 188ISO 1307ISO 1402ISO 4671:2007ISO 7326:2006ISO 8033:2006ISO 8330ISO 10619-2:2011EN 1947EN 14540ISO 9001ISO 23529ISO 30013购买本文件时可提供的所有现行修订均包含在购买本文件中。

BS ISO 4642-2:2015 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 (see Clause 4).This part of ISO 4642 applies to delivery hoses for fire-fighting purposes intended for use at a minimum ambient temperature of -20 °C.Hoses conforming to this part of ISO 4642 are intended to be used with fire hose couplings conforming to the relevant national standards couplings.Requirements are also given for hose assemblies (see 6.12) where these are fitted by the hose manufacturer.NOTE 1 Hoses for use at temperatures lower than -20 °C can be supplied by agreement between the manufacturer and purchaser.NOTE 2 All pressures are expressed in megapascals where 1 MPa = 10 bar.Cross References:ISO 176:2005ISO 188ISO 1307ISO 1402ISO 4671:2007ISO 7326:2006ISO 8033:2006ISO 8330ISO 10619-2:2011EN 1947EN 14540ISO 9001ISO 23529ISO 30013All current amendments available at time of purchase are included with the purchase of this document.
