DIN EN 1254-6
Copper and copper alloys - Plumbing fittings - Part 6: Fittings with push-fit ends
|Publication Date:||1 December 2012|
|ICS Code (Metal fittings):||23.040.40|
This European Standard specifies materials and test requirements for fittings of copper and copper alloys.
This part of EN 1254 specifies push-fit end connections with or without plating or coating in the size range 6 mm to 54 mm for the purpose of joining tubes of copper, plated copper, multilayer pipes and plastics pipes, intended for use in hot and cold water systems according to EN 806, which are designed for service lifetime up to fifty years, as well as heating and cooling systems.
Permissible operating temperatures and maximum operating pressures are also established.
Fittings may comprise a combination of end types, specified in this European Standard, EN 1254, or other standards, providing they are suitable for the fluid being conveyed.
The standard establishes a designation system for the fittings.
This European Standard is applicable to push-fit fittings for joining one or more of the following tubes or pipes:
- Copper tubes to EN 1057;
- PE-X pipes to EN ISO 15875-2;
- PB pipes to EN ISO 15876-2;
- PP pipes to EN ISO 15874-2;
- PE-RT pipes to EN ISO 22391-2;
- Multilayer pipes to EN ISO 21003-2.
Fittings may be suitable for joining other tubes and pipes provided the push-fit joint with the specified tube or pipe meets the requirements of this standard.
Operating temperatures and pressures
For joints with copper tubes
It is essential that operating temperatures and maximum operating pressures for assembled joints do not exceed the values
For joints with multilayer and plastics pipes
The operating temperatures and maximum operating pressures for the assembled joints should be determined in accordance with multilayer or plastics pipe material properties, details of which are specified in the relevant multilayer and plastics piping system standards.
