NF EN ISO 6224, T47-257 (05/2024)

This International Standard specifies the requirements for general purpose pipes made of thermoplastic materials with textile reinforcement for water delivery. Three types of pipes are specified according to their service conditions, i.e. their ambient temperature and water temperature ranges: — ambient temperatures: -10 °C to +60 °C; — operating water temperatures: 0 °C to +60 °C. NOTE For water temperatures above 23°C and particularly above 40°C, the maximum operating pressure will be reduced. These hoses are not intended for use for transporting drinking water, connecting washing machines, as fire hoses, for special agricultural machinery or as watering hoses for the general public market.
