标准范围

ISO 4642-1:2009规定了与固定系统一起使用的消防用半刚性卷盘软管的要求和试验方法。对于内径为19 mm和25 mm的软管，软管的最大工作压力为1.2 MPa，对于内径为33 mm的软管，软管的最大工作压力为0.7 MPa。符合ISO 4642-1:2009标准的软管适用于使用间隔时间较长的应用场合，例如建筑物和其他建筑工程中的固定消防软管卷盘。ISO 4642-1:2009仅适用于在非环境条件下使用的消防软管-温度范围为-20°C至+60°C的腐蚀性或非腐蚀性环境。

ISO 4642-1:2009 specifies the requirements and test methods for semi-rigid reel hoses for fire-fighting purposes for use with fixed systems. The hoses are intended for use at a maximum working pressure of 1,2 MPa for hoses of 19 mm and 25 mm inside diameter and 0,7 MPa for hoses of 33 mm inside diameter.Hoses conforming to ISO 4642-1:2009 are intended for applications where long intervals can occur between the occasions of use, for example on fixed fire hose reels in buildings and other construction works.ISO 4642-1:2009 applies exclusively to hoses for fire-fighting purposes intended for use at ambient conditions in non-aggressive or non-corrosive atmospheres within the temperature range minus 20 °C to plus 60 °C.
