21、blicationsInside back coverISO 10692-1:2001(E) iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each
22、 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 non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internationa
23、l Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for
24、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 this part of ISO 10692 may be the subject of patent rights. ISO shall not be held responsible for identifying an
25、y or all such patent rights. International Standard ISO 10692-1 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2, Cylinder fittings. ISO 10692 consists of the following parts, under the general title Gas cylinders Gas cylinder valve connections for use in the micro-ele

28、ticles are demanded for the manufacture of microelectronic components or similar applications. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 10692. For dated references, subsequent amendmen
29、ts to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 10692 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of
30、the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

33、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 corrosion (see ISO 11114-1).

34、 For these connections the outboard leak rate shall not exceed a value of 1 10 7 mbar l s 1 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 than 1 10 9 mbar l s 1 . The gasket shall be an unused r
35、ecessed 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 ISO 6506-1) with a surface finish 0,8 m turned in the sealing area. Gaskets of other materials, e.g. polymers, may be used if they do not compro
36、mise 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 Conditions of use may cause significant differences in both the inboard and outboard leak rates, e.g. nickel gaskets should be used only once. 3.3 Ma
37、rking The valves shall be marked with the requirements listed in ISO 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 the connection in the assembled state (view from the to
38、p). 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 vertically oriented. The antirotational device shall alw
39、ays 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 8.3. The union nut shall have two venting holes opposite
40、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 is given in clause 9. The diameters d A , d B , d M and
41、 d N 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 d A and d B on the valve outlet as well as d M and d N on the nipple shall be concentric within
42、 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 d A , d B , d M and d N for the 630 and 640 series connections are
43、given in Table 1.
