It shall be used in conjunction with part 1. This document is valid for maximum media temperatures up to 120 °C and, occasionally peak temperatures up to 140 °C for maximum 300 h/a, and a design pressure up to 2,5 MPa for a design lifetime of at least 30 years. This document covers surveillance systems. In conjunction with the other parts of EN 15632, this document is applicable to pipes, fittings, their joints and to joints with components made of non-plastics materials intended to be used for district heating installations.
