21、s). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and n
22、on-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Pa
23、rt 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of
24、this part of IS0 10692 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights.

32、- For valve and nipple: AISI 316L, microfinished, hardness at least 130 HBW in accordance with IS0 6506-1; - For the union nut: AISI 304, threading silver plated. Other materials and values may be chosen if they give at least equivalent performance in terms of yield stress and resistance to corrosio
33、n (see IS0 11 114-1). 1 EN IS0 10692-f:dO01 3.2 Operation For these connections the outboard leak rate shall not exceed a value of 1 x 10-7 mbar.lw1 at 137 bar helium when the connection is tightened to 50 N.m. When this outboard leak rate is obtained, an inboard helium leak rate shall be no greater
34、 than 1 x 10-9 mbar.lw1 The gasket shall be an unused recessed flat, uncoated gasket of Ni 200, fully annealed with the requirements of 8.1. Its hardness shall be HBW 2,5/62,5: 80 to 100 HBW (in accordance with IS0 6506-1) with a surface finish 0,8 pm turned in the sealing area. Gaskets of other mat
35、erials, e.g. polymers, may be used if they do not compromise the leak integrity of the connection and are compatible with the duty. These gaskets shall be used at a torque appropriate for the material. NOTE should be used only once. Conditions of use may cause significant differences in both the inb
36、oard and outboard leak rates, e.g. nickel gaskets 3.3 Marking The valves shall be marked with the requirements listed in IS0 10297, as far as appropriate. In addition to all the required valve marking the letters “nnn“, where nnn is the outlet number, shall be marked. 4 General design Figure 1 shows
37、 the connection in the assembled state (view from the top). The nipple tip has two notches to facilitate the removal of the gasket. A pair of keys on the nipple and of the corresponding key ways on the valve prevent rotation of the parts during assembly. The keys shall be opposite to each other and
38、vertically oriented. The antirotational device shall always be in place. The nut shall not engage on the outlet thread until the antirotational pins fitted to the plug are engaged in the slots on the valve outlet. An alternative way to design the antirotational device of the nipple is described in 8
39、.3. The union nut shall have two venting holes opposite to each other. 5 Dimensions Dimensions for the outlet connections are given in Figures 2 to 9. Only dimensions explicitly given there are mandatory. Others shall be chosen as appropriate. All dimensions are in millimetres. The thread definition
40、 is given in clause 9. The diameters dA, dB, dM and dN are not dimensioned in the figures because they assume different values for each connection. They are chosen in such a way that combinations other than the intended ones are impossible. The diameters dA and dB on the valve outlet as well as dM a
41、nd dN on the nipple shall be concentric within 0,05 mm full indicator movement because these are critical dimensions for safety. 6 630 and 640 series connections Details of the valve outlet are given in Figure 2. Figure 3 gives details of the nipple. The values of the diameters dA, dB, dM and dN for
42、 the 630 and 640 series connections are given in Table 1.
