The work of preparing International Standards is normally
6、 carried out through ISO 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 non-governmental, in liaison with ISO, also take part in the w
7、ork. ISO 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, Part 2. The main task of technical committees is to prepare Int
8、ernational Standards. 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. In exceptional circumstances, when a technical comm
9、ittee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature
10、and does not have to be reviewed until the data it provides are considered to be no longer valid or useful. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent r
11、ights. ISO/TR 11364 was prepared by Technical Committee ISO/TC 58, Gas cylinders.iv ISO 2012 All rights reserved ISO/TR 11364:2012(E) Introduction There is a huge variety of valve to gas cylinder neck thread connections worldwide and ISO cylinders are free to be equipped with any thread according to
12、 a recognized thread standard. ISO standards for cylinders and valves require the marking of an identification of the thread on valve and cylinder but there is presently no harmonized marking system. The purpose of this Technical Report is to list all known cylinder/valve threads currently used and
13、also threads used in the past and to specify a harmonized identification code and marking system for both cylinders and valves. The aim is to reduce the risk of mismatches when valves are fitted to gas cylinders and avoid related safety incidents. ISO 2012 All rights reserved v Gas cylinders Compila
14、tion of national and international valve stem/gas cylinder neck threads and their identification and marking system 1 Scope This Technical Report lists the different valve stem to gas cylinder connection threads currently and historically existing worldwide and provides official coded designations f
15、or them. These coded designations will then be available for identification and marking purposes. It also gives guidance concerning which threads are dimensionally identical and which are interchangeable. Furthermore, this T echnical Report provides guidance for valving procedures when fitting valve
16、s to gas cylinders. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 13
17、341, Gas cylinders Fitting of valves to gas cylinders 3 Interchangeability of valve/cylinder threads Threads of recognized standards which are dimensionally identical but have historically been named differently are fully interchangeable. Experience has shown that the following combination of thread
18、s can be safely used in service: 25E valve with T8, T23 and T26 cylinder threads. However, for small steel (less than 5 l water capacity) and aluminium alloy cylinders, users should examine the suitability of the resulting combination for each application in order for them to be interchangeable. 4 L
19、ists of threads 4.1 General The lists of threads are given in Table 1 for taper threads and Table 2 for parallel threads. The columns in the tables have the following meaning: Column 1 Ref. No. Reference Number of the thread starting with a “T” for taper threads and “P” for parallel threads; followe
20、d by a consecutive number in the order as they are listed. Column 2 Origin Country or region of origin of the thread. Column 3 Nominal designation of thread TECHNICAL REPORT ISO/TR 11364:2012(E) ISO 2012 All rights reserved 1 ISO/TR 11364:2012(E) Nominal dimensional identification or designation of
21、the thread given in its originating standard or specification. Column 4 Specification or standard Specification or standard from which the thread originated (see also the bibliography). Column 5 Official mark to standard If the originating standard indicates an official abbreviated identification ma
22、rk or code, it is given in this column. Column 6 Identification and marking This column indicates an identification code for the relevant thread assigned under this Technical Report which shall in future be used for marking purposes. NOTE This simplified marking code covers for parallel threads the
23、thread size only and not the geometry of the sealing area or surface. Column 7 Note This column indicates specific equivalency or interchangeability with other threads listed. Column 8 Recommended valving procedure This column indicates the recommendations for fitting valves to gas cylinders, in par
24、ticular the recommended torque values to be used, which normally follow the requirements of ISO 13341. 4.2 List of threads See Table 1.2 ISO 2012 All rights reserved ISO/TR 11364:2012(E)Table 1 List of national and international valve/gas cylinder threads Ref. no.
