标准范围

本文件规定了消防用橡胶和塑料吸入软管的要求和试验方法。这些软管也可以手动用于向泵供应无压水或用于排水。注？所有压力均以兆帕和巴（1兆帕=10巴）表示。对于软管组件，即已安装联轴器的软管，规定了附加要求，由软管制造商执行（见第8条）。A类（橡胶）软管的最低使用温度为20℃，B类（热塑性塑料）软管的最低使用温度为10℃。

This document establishes the requirements and test methods for rubber and plastics suction hoses for fire-fighting purposes. These hoses can also be used manually to supply unpressurized water to the pump or for water discharge.NOTE       All pressures are expressed in megapascals and in bar (1 MPa = 10 bar).Additional requirements are specified for hose assemblies, that is, hoses with couplings already fitted, where this is carried out by the hose manufacturer (see Clause 8).Type A (rubber) hoses are intended for use at a minimum temperature of？20 °C and Type B (thermoplastics) hoses are intended for use at a minimum temperature of？10 °C.
