This European Standard specifies requirements, assessment methods, compliance criteria and a designation system for press fittings for metallic tubes. The fitting ends have a size range from 6 mm to 108 mm. The press fittings are designed for a service lifetime up to fifty years.
Press fittings produced to this standard are suitable for joining:
- copper tubes to EN 1057 and
- stainless steel tubes to EN 10312
with wall thicknesses and tempers as specified by the manufacturer.
Unless otherwise specified by the manufacturer, to ensure that tubes can withstand the radial pressing forces involved, the wall thicknesses given in Annex A shall be the minimum suitable for jointing by press fittings.
Fittings may be suitable for joining other metallic tubes provided the press joint with the specified tube meets the requirements of this standard.
This European Standard applies to fittings made of materials listed in CEN/TS 13388.
Adaptor fittings for use with copper tubes may combine press ends with fitting ends defined in the other parts of EN 1254.
Press fittings for metallic tubes may also have flanged end connections according to EN 1092-3.
Press fittings for metallic tubes 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.
b) gas applications:
natural gas and liquefied petroleum gas systems with a maximum operating pressure less than or equal to 5 bar;
compressed air.
The fittings are intended to be used up to the operating temperatures and maximum operating pressures as indicated in Annex A for the relevant application.
