This International Standard specifies the requirements for four types of flexible thermoplastic hose, textile
reinforced, for compressed-air applications in the temperature range from - 10 ℃ to + 60 ℃.
The four types are classified as light service for a maximum working pressure of 7 bar at 23 ℃ and 4,5 bar at
60 ℃, medium service for a maximum working pressure of 10 bar at 23 ℃ and 6,5 bar at 60 ℃, heavy
service for a maximum working pressure of 16 bar at 23 ℃ and 11 bar at 60 ℃, and heavy service for use in
mining for a maximum working pressure of 25 bar at 23 ℃ and 13 bar at 60 ℃.
