This European Standard provides classification; general requirements and test methods for flexible; preinsulated; directly buried district heating pipe systems. It is intended to be used in conjunction with parts 2; 3; 4; and 5. Depending on the pipe assembly (see Table 4);This European Standard is valid for maximum operating temperatures of 95 ℃ to 140 ℃ and operating pressures of 6 bar to 25 bar. The pipe systems are designed for a lifetime of 30 years. For pipe systems with plastic service pipes; the respective temperature profiles are defined in EN 15632-2 and EN 15632-3. NOTE For the transport of other liquids; for example potable water; additional requirements may be applicable.
