PD CEN/TR 18341:2026

This standard PD CEN/TR 18341:2026 District heating and cooling systems. Supplementary information on usage of CEN/TC 107 documents is classified in these ICS categories:

• 23.040.07 Pipelines and its parts for district heat
• 23.040.99 Other pipeline components

This document provides an overview of the standardization deliverables published and under development under the responsibility of CEN/TC 107. It defines the temperature ranges applicable to the intended use of these documents and establishes a classification system linking each document to its corresponding temperature range. Furthermore, it describes how estimation of service life of pipe systems is conducted based on the average operating temperature within service pipes, taking into account additional influencing conditions.
