Technical regulation and scope of the EN 1254-5 standard
The European standard EN 1254-5 is a key regulatory document defining the requirements for the design, manufacture, and quality control of plumbing fittings made of copper and copper alloys. At EV Group China, we strictly adhere to these protocols in the production of fittings intended for capillary soldering of copper pipelines.
The main provisions of the standard include:
- Regulations for the selection of the chemical composition of materials, including options with and without protective coatings.
- Precise geometric parameters, tolerances, and mating dimensions to ensure joint tightness.
- Methodology for conducting acceptance tests for strength and leak-tightness.
- Establishment of critical values for operating pressure and temperature depending on installation conditions.
This part of the EN 1254 standard regulates the specifications for short-end fittings intended for integration into systems using copper pipes that comply with EN 1057 specifications. The engineering department at EV Group China ensures full compliance of manufactured products with these requirements, guaranteeing the reliability of capillary soldering during the professional installation of utility networks.
