Resumen:
This European Standard specifies product characteristics, assessment methods, compliance criteria of the test results and a designation system for compression fittings for connecting with copper tubes. Compression fittings exist with sealing elements - metallic and/or non-metallic - called non manipulative (commonly referenced as type A) and without sealing elements, called manipulative (commonly referenced as type B). For the purposes of joining copper tubes, the fitting ends have a size range from 6 mm to 108 mm. The compression fittings are designed for a service lifetime up to fifty years.The fittings are used up to the operating temperatures and maximum operating pressures as indicated in Annex A.This European Standard applies to copper alloy fittings. A non-exhaustive list of these copper alloys is given in CEN/TS 13388.Compression fitting ends, Type A, are used with copper tubes to EN 1057 in all material hardness conditions.NOTE Compression fittings, Type A, will possibly require an internal support when used with R220 (annealed) copper tube and the manufacturer's advice should be sought. Compression fitting ends, Type B, are used with R220 (annealed) or R250 (half-hard) copper tube to EN 1057.NOTE Compression fittings, Type B, may be used with R290 (hard) copper tube and the manufacturer's advice should be sought.Adaptor fittings for use with copper tubes may combine compression ends with fitting ends defined in the other parts of EN 1254.Compression fittings for use with copper tubes may also have flanged end connections according to EN 1092-3.Compression fittings for use with copper tubes may also have a plated or other decorative surface coating.Fittings can be produced by metal forming, casting, or fabrication.Products covered by this standard are intended to be used in: a) liquid applications: hot or cold or combined hot and cold water systems according to EN 806; closed heating systems according to EN 12828 and cooling systems; drainage systems; sprinkler systems according to EN 12845.b) gas applications: natural gas and liquefied petroleum gas systems with a maximum operating pressure less than or equal to 5 bar according to EN 1775; compressed air.
