| Subject of the standard: | This document specifies product characteristics, assessment methods, compliance criteria of the test results and a designation system for threaded fittings. These threaded ends exist with metallic and with non-metallic sealing elements for the purposes of joining with tubes, pipes, fittings or valves, the threaded ends have a size range from 3,175 mm (1/8") to 101,6 mm (4"). The threaded fittings are designed for a service lifetime up to fifty years. The fittings are used up to the operating temperatures and corresponding maximum operating pressures as indicated in Annex A. This document applies to copper alloy fittings. A non-exhaustive list of these copper alloys is given in CEN/TS 13388. Threaded fittings may also have flanged end connections according to EN 1092-3. Threaded fittings may also have a plated or other decorative surface coating. Fittings can be produced by machining, metal forming, casting, or fabrication. |
