Scope

This standard specifies the requirements for four types of general-purpose fabric-reinforced thermoplastic collapsible water hoses, whose operating temperature range is -10°C to 55°C. This type of hose is divided into the following four types:
　——Low pressure, designed for the highest working pressure: 0.4MPa when below 23°C, and 0.2MPa when below 55°C;
　——Medium pressure, designed for the highest working pressure: when Maximum 0.7MPa when below 23℃, maximum 0.36MPa when below 55℃;
　——High pressure, designed for the highest working pressure: maximum 1.0MPa when below 23℃, maximum 0.51MPa when below 55℃;
　——Ultra-high pressure, designed for the highest working pressure Pressure: Maximum 1.55MPa when below 23℃, maximum 0.70MPa when below 55℃. This standard does not apply to fire hoses or hoses for conveying drinking water.
