11363-22010 ISO 11363-22010E iv ISO 2010 – All rights reserved 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 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 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 International 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. 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 rights. ISO 11363-2 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2, Cylinder fittings. This first edition of ISO 11363-2 cancels and replaces ISO 11116-21999 and ISO 111911997. ISO 11363 consists of the following parts, under the general title Gas cylinders 17E and 25E taper threads for connection of valves to gas cylinders ⎯ Part 1 Specifications ⎯ Part 2 Inspection gauges 标准分享网 w w w .b z f x w .c o m 免费下载 w w w . b z f x w . c o m BS EN ISO 11363-22010 ISO 11363-22010E ISO 2010 – All rights reserved v Introduction Gas cylinders intended to contain compressed, liquefied or dissolved gas under pressure are fitted with accessories to allow release and refilling of gas. Hereinafter, the term “valve” will apply to such accessories. The connection between cylinder and valve is obtained by assembly of two taper-threads an external one on the valve stem and an internal one in the cylinder neck, both having the same nominal taper, thread pitch and thread profile. w w w . b z f x w . c o m BS EN ISO 11363-22010 标准分享网 w w w .b z f x w .c o m 免费下载 w w w . b z f x w . c o m BS EN ISO 11363-22010 INTERNATIONAL STANDARD ISO 11363-22010E ISO 2010 – All rights reserved 1 Gas cylinders 17E and 25E taper threads for connection of valves to gas cylinders Part 2 Inspection gauges 1 Scope This part of ISO 11363 specifies types, dimensions and principles of use of gauges, to be used in conjunction with the taper threads specified in ISO 11363-1 i.e. 17E and 25E threads. It provides examples of calculations for thread gauge dimensions on the large end diameter Annex A and draws attention to the limitations of the gauging system specified Annex B. 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 11363-1, Gas cylinders 17E and 25E taper threads for connection of valves to gas cylinders Part 1 Specifications 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 11363-1 and the following apply. 3.1 check gauge gauge for checking dimensional conity of inspection gauges NOTE This gauge is not used for gauging cylinder neck threads or valve stem threads. 3.2 inspection gauge gauge used for the routine gauging of cylinder neck and valve stem threads NOTE This gauge is not used for checking other gauges. 3.3 single-part gauge gauge of sufficient length to contact the length of full taper threads NOTE These gauges are either plugs or rings, plain or threaded. w w w . b z f x w . c o m BS EN ISO 11363-22010 ISO 11363-22010E 2 ISO 2010 – All rights reserved 3.4 two-part gauge gauge consisting of two separate inspection gauges, used in combination, where one is used to contact the large end of the taper cone and the other the small end NOTE These sets of gauges are either plugs or rings, plain or threaded. 4 Requirements 4.1 Materials All gauges shall be manufactured from material of suitable strength, stability and hardness. 4.2 Thread profile The thread profile of threaded inspection and check gauges shall be as shown in Figure 1. The thread profile is a British Standard Whitworth BSW1 with a 55 angle see Figure 1. 1 A coarse thread devised and standardized in 1841 by British engineer Sir Joseph Whitworth 1803-87. It has an angle of thread of 55 and ranges in size from 1/16 in to 2 1/2 in. It is used in many types of engineering throughout the world, although in the UK its use is now being superseded by the ISO metric system ISO 68-1. 标准分享网 w w w .b z f x w .c o m 免费下载 w w w . b z f x w . c o m BS EN ISO 1136
