This International Standard specifies the minimum requirements for textile-reinforced, smooth-bore rubber water-suction and discharge hoses and hose assemblies.
Three types of hoses and hose assemblies are specified according to their operating duty requirements, i.e. their ambient and water temperature ranges:
— ambient temperatures: -25 ℃ to +70 ℃;
— water temperatures during operation: 0 ℃ to +70 ℃.
