本文件规定了工厂制造的柔性埋地区域供暖管道系统的分类、一般要求和试验方法。 本文件拟与第2、3或4部分（如适用）结合使用。 根据管道组件（见表4），本文件适用于95°C（第2部分和第3部分）的最高工作温度和120°C（第4部分）的最高工作温度以及0.6 MPa至2.5 MPa的设计压力。 管道系统的设计使用寿命至少为30年。 对于带有塑料供水管的管道系统，EN 15632-2和EN 15632-3中规定了各自的温度分布。 注:对于其他液体的运输，例如饮用水，可适用其他要求。

This document specifies classification, general requirements and test methods for flexible, factory made, buried district heating pipe systems. This document is intended to be used in conjunction with part 2, 3 or 4, as applicable. Depending on the pipe assembly (see Table 4), this document is applicable to a maximum operating temperature of 95 °C (part 2 and 3) and a maximum operating temperature of 120 °C (for part 4) and design pressures of 0,6 MPa to 2,5 MPa. The pipe systems are designed for a service life of at least 30 years. For pipe systems with plastic service pipes, the respective temperature profiles are specified in EN 15632-2 and EN 15632-3. NOTE For the transport of other liquids, for example potable water, additional requirements can be applicable.
