This class of hose is further divided
13、 into Type 1 and Type 2 according to the design working pressure (see Clause 4). NOTE 1 The requirements and test methods for other types of rubber and plastics suction hoses for fire-fighting purposes are specified in BS EN ISO 14557:2002.This standard is applicable to hoses and hose assemblies tha
