Copper and copper alloys - Plumbing fittings - Part 1: Fittings for capillary soldering or capillary brazing to copper tubes prEN 1254-1 rev

Scope

This European Standard specifies requirements, assessment methods, compliance criteria and a designation system for fittings with ends for capillary soldering or capillary brazing to copper tubes e.g. EN 1057, EN 13348, EN 13349, EN 12735-1, EN12735-2 etc. For the purposes of joining copper tubes, the fitting ends have a size range from 6 mm to 108 mm. These fitting ends exist in three forms: end feed fittings and integral solder and integral brazing ring fitting ends. The fittings are designed for a service lifetime up to fifty years.
This European Standard applies to fittings made of materials listed in CEN/TS 13388.
The fittings for capillary soldering or capillary brazing to copper tubes are intended to be used with solder alloys in accordance with alloys specified in EN ISO 9453 and brazing alloys in accordance with alloys specified in EN ISO 17672.
Adaptor fittings for use with copper tubes may combine capillary soldering or capillary brazing ends with fitting ends defined in the other parts of EN 1254.
Capillary soldering or capillary brazing fittings may also have flanged end connections according to EN 1092-3.
Capillary soldering or capillary brazing fittings may also have a plated or other decorative surface coating.
Products covered by this standard are intended to be used in:
a) liquid applications:
 hot or cold or combined hot and cold water systems;
 heating and cooling systems;
 drainage systems;
 sprinkler systems;
 refrigeration.
b) gas applications:
 natural gas and liquefied petroleum gas systems with a maximum operating pressure less than or equal to 5 bar;
 medical gases;
 compressed air;
 refrigeration.
The fittings are intended to be used up to the operating temperatures and maximum operating pressures as indicated in Annex A for the relevant soldering or brazing alloy.
