This European Standard specifies requirements, types of fixing and connection, designation and testing for hose fittings with clamp units for hoses made of rubber/plastics or thermoplastics preferably for use with flammable and non-flammable products. It contains requirements for hose fittings to ensure that, when used appropriately, the user or third persons are not exposed to hazards from fire, explosions or acid burns, for example from mineral oils or chemicals, and that the environment is protected from pollution and other detritus. For maximum working pressure (WP) and temperature see 4.3. WARNING - Before decoupling of the quick coupling connections according to Parts 6, 7 and 8, the assembly should be at atmospheric pressure.
