This European Standard shall be given the status of a national standard, either by publication of an identical text or
16、by endorsement, at the latest by July 1998, and conflicting national standards shall be withdrawn at the latest by July 1998. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 8, Copper and copper alloy fittings, to prepare the following standard: EN 1254-1, Copper
17、 and copper alloys Plumbing fittings Part 1: Fittings with ends for capillary soldering or capillary brazing to copper tubes. This standard is one of five parts for copper and copper alloy fittings for joining copper tubes or plastics pipes. The other four parts of the standard are: EN 1254-2, Coppe
18、r and copper alloys Plumbing fittings Part 2: Fittings with compression ends for use with copper tubes. EN 1254-3, Copper and copper alloys Plumbing fittings Part 3: Fittings with compression ends for use with plastics pipes. EN 1254-4, Copper and copper alloys Plumbing fittings Part 4: Fittings com
19、bining other end connections with capillary or compression ends. EN 1254-5, Copper and copper alloys Plumbing fittings Part 5: Fittings with short ends for capillary brazing to copper tubes. It is recommended that fittings manufactured to this standard are certified as conforming to the requirements
20、 of this standard, based on third party testing and continuing surveillance, which should be coupled with an assessment of a suppliers quality system against the appropriate standard, i.e. EN ISO 9001 or EN ISO 9002. In respect of potential adverse effects on the quality of water intended for human
21、comsumption, caused by the product covered by this standard: 1) this standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; 2) it should be noted that, while awaiting the adoption of verifiable European criteria, exis
22、ting national regulations concerning the use and/or the characteristics of this product remain in force. The attention of the user of this standard is drawn to the fact that national or local regulations or practices might restrict the choice of dimensions and threads in the application of products
23、conforming to this standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembo

28、r and copper alloys with or without plating. Maximum permissible temperatures and pressures are also established. This part of EN 1254 specifies connection end dimensions of capillary soldering and brazing ends for the purposes of joining copper tubes specified in EN 1057. Fittings may comprise a co
29、mbination of any of the end types specified in EN 1254-1 to EN 1254-5 or other standards. The standard establishes a designation system for the fittings. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications.

NOTE Informative references to documents used in the preparation of this standard, and cited at the appropriate places in the text, are listed in a bibliography, see annex C. 3 Definitions For the
35、purposes of this standard, the following definitions apply. 3.1 plumbing fitting device used in a tube system for the purpose of connecting the tubes either to each other or to a component part of a system 3.2 capillary end end in which the joint is made by the flow of solder or brazing alloy by cap
36、illary action into the annular space 3.3 reducer (capillary soldering or brazing for copper tube) component used to enable an end to connect tube of a smaller nominal diameter than the nominal diameter of the fitting end 3.4 adaptor fitting fitting combining more than one type of end NOTE For detail
37、s of the other ends, see the relevant parts of this standard or other standards. 3.5 nominal diameter nominal diameter of the fitting end expressed as the nominal outside diameter of the connecting tube 4 Requirements 4.1 General Fittings shall conform to the requirements of 4.2 to 4.5 and shall be
38、capable of meeting the type testing requirements of 4.6. Reducers also shall conform to these requirements. 4.2 Materials 4.2.1 General Fittings shall be made from copper or copper alloys selected from materials either: specified in European copper and copper alloy product standards; or registered b
39、y CEN/TC 133; provided that the fittings manufactured from them meet the functional requirements of this standard. NOTE Some of the standardized coppers and copper alloys commonly used for the manufacture of fittings are shown in Table 1. Details of registered alloys can be obtained from the CEN/TC

41、2 NOTE These examples do not constitute an exhaustive list. 4.2.2 Restrictions in the choice of materials Cu-ETP (CW004A) is a permitted material only for integral solder ring fittings and shall not be used for other types of capillary fittings. Leaded solders shall not be used for manufacture of in
42、tegral solder ring fittings. 4.3 Dimensions and tolerances 4.3.1 Tolerances on diameters The standardized nominal dimensions, diameters and their tolerances are given in Table 2. The socket and male end tolerances on diameter shall be in accordance with Table 2, which shall be verified by the use of
43、 gauges shown in Figures 5 and 6 and Tables 7 and 8. NOTE 1 Tolerances in accordance with Table 2 and the use of gauges in accordance with Tables 7 and 8 will ensure the distribution of solder or brazing alloy throughout the joint and will allow for the alignment of the male end of a fitting or the
44、free end of a tube in the socket. NOTE 2 When capillary fittings are used for soldering or brazing to copper tubes, the ends of the tubes should be sized to the outside diameter dimensions specified in Table 2 for a length not less than the length of engagement of the fitting. NOTE 3 Socket and male
45、 ends are shown diagrammatically in Figures 1 and 2. NOTE 4 The installation dimensions cannot be standardized due to varying manufacturing processes. The manufacturer should be consulted for these dimensions. 4.3.2 Minimum lengths of engagement The minimum lengths of engagement of sockets and male
46、ends shall be in accordance with Table 3. The length, L 1 , for integral solder ring fittings or integral brazing ring fittings shall not include the width of the solder or brazing alloy groove see Figure 1b). Male ends intended for use with integral ring sockets shall include an allowance for the w
47、idth of the solder or brazing alloy groove. 4.3.3 Minimum bore area The minimum cross-sectional area of the bore through each fitting shall be not less than the theoretical minimum area of the bore given in Table 4, except that for unequal-ended or adaptor fittings with ends specified in EN 1254-2,
48、EN 1254-3, EN 1254-4 and EN 1254-5 or other standards, the smallest diameter shall apply provided that this diameter does not restrict other outlets.Page 5 EN 1254-1:1998 BSI 1998 Table 2 Tolerances on the nominal diameter Values in millimetres Nominal diameter Tolerances on the mean diameter 1) wit
