6、rstoffe - Hochdruckkupplungen This Technical Specification (CEN/TS) was approved by CEN on 16 December 2013 for provisional application. The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their comments, particula
7、rly on the question whether the CEN/TS can be converted into a European Standard. CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available promptly at national level in an appropriate form. It is permissible to keep conflicting n

PD CEN/TS 16650:2014 CEN/TS 16650:2014 (E) 4 1 Scope This Technical Specification specifies requirements for couplings of 2 in (50,8 mm), 2 in (63,5 mm), 3 in (76,2 mm) and 4 in (101,6 mm) nominal sizes with ribbed tails and hexagons for use at pressure
16、s not exceeding 1 550 kN/m 2(225 lbf/in 2 ). For assembly of coupling, see Figure 1. This document is applicable to couplings which have been designed primarily for aircraft refuelling purposes, but they may also be used for other general purposes. 2 Normative references The following documents, in
17、whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

20、ted limits of size 3 Information to be supplied by the purchaser It is essential that the purchaser states in the enquiry and order, the form of screw thread required (see Clause 8). 4 Designation of sizes of couplings The size by which the coupling is designated shall be the nominal bore of the hos
21、e with which it is to be used. 5 Materials The material used in the manufacture of the couplings shall be as follows: a) Gunmetal castings conforming to Specification CC 491 K of EN 1982:1998 b) Brass castings conforming to Specification CC 750 S of EN 1982:1998 6 Dimensions The dimensions of coupli
22、ngs and union nuts shall conform to those shown on Figure 2, Figure 3 and Figure 4 and in Table 1, Table 2 and Table 3.

23、4 CEN/TS 16650:2014 (E) 5 7 Coupling finish The couplings shall be machined all over including the bores. All burrs and sharp edges shall be removed. 8 Screw threads The coupling assembly is given in Figure 1. The couplings shall be screwed with either: a) Whitworth BSP threads. The threads on the l
24、iner of the union nut (Figure 4 and Table 3) parallel threads as specified in EN ISO 228-1 and EN ISO 228-2. Thread undercuts shall conform to BS 1936-1. b) Metric threads. The threads on the liner of the union nut (Figure 5 and Table 4) shall conform to BS 3643-2:2007, Table 4, Tolerance class 6H (
25、medium fit) and BS 3643-2:2007, Table 5, Tolerance class 6g (medium fit). Thread undercuts shall conform to BS 1936-2 It is essential that the purchaser states in the enquiry and order which threads are required. 9 Washers Washers shall be made of specially selected leather or synthetic rubber in ac
26、cordance with BS 2751. 10 Bonding The couplings shall be fitted to the hose so that the electrical bonding, as specified in the relevant standard, is maintained for the hose assembly. 11 Hydrostatic test All couplings, when assembled without hose, shall be subjected to a hydrostatic test of 3 100 kN
27、/m 2(450 lbf/in 2 ). The test shall be applied after all machining operations have been completed. This test is for the purpose of locating flaws in the material after machining, and also to test the merits of the joint. When couplings are being assembled for the hydrostatic test, only the appropria
28、te standard wrench or spanner shall be used in tightening them. Use shall not be made of an extension on the handle of the wrench or spanner, or of other means to produce excessive tightness. Couplings conforming to this Technical Specification shall not show signs of leakage during this test by rea
29、son either of a defective joint or of other defects. 12 Identification marking Each set of couplings shall be legibly and permanently marked with: a) the manufacturers identification; b) the number and date of this Technical Specification; c) the following letters to indicate the type of screw threa
