Foreword to amendment A1BS EN ISO 13341:2010ISO 13341:2010(E) ISO 2010 All rights reserved iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO mem
22、ber 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, governmen
23、tal 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 Direc
24、tives, 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 bodi
25、es 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 13341 was prepared by Technical Committee ISO/TC 58, Gas cylinders. This secon
26、d edition cancels and replaces the first edition (ISO 13341:1997), which has been technically revised. It also incorporates the Technical Corrigendum ISO 13341:1997/Cor.1:1998.

It specifically applies to al
28、l valve and cylinder combinations connected with ISO screw threads as specified in ISO 10920 and ISO 11363-1. It defines routines for inspection and preparation prior to valving for both taper and parallel screw threads. Torque values are given in Annex A for steel and aluminium gas cylinders includ
29、ing composite cylinders with steel or aluminium boss. NOTE The procedures and practices specified in this International Standard can be beneficially applied to other valve to cylinder screw thread connection systems. ISO/TR 113644lists the valve to gas cylinder threads in use worldwide. It gives det
30、ails of the thread identification codes, whether the threads are interchangeable with ISO threads and if the taping procedure and torque values specified in this International Standard can be used. ISO/TR 113644gives clear guidance for the method and torque for all listed inlet threads, which are no
31、t interchangeable. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

34、: Specification 3 General requirements and recommendations Gas cylinders and valves shall be connected so that when in use the combination is gas tight and the valve cannot be removed inadvertently from the cylinder. The tools used to screw the valve into the gas cylinder shall fit the valve properl
35、y and the gas cylinder shall be secured against rotation during the torquing process. The tools shall not cause damage to either the valve or the cylinder. Minor marks to the valve and the cylinder are acceptable. The cylinder and the valving tool axes shall be aligned. In addition, some composite c
36、ylinders need special treatment for the valving process, for example fixing the neck/metal boss during torquing. Any special instructions given by the cylinder manufacturer shall be followed.

37、ights reservedSealing materials used between the valve stem and cylinder neck threads shall be compatible with the gas to be contained in the cylinder (e.g. oxygen), in accordance with ISO 11114-2. Except as described in 7.3, the torque applied to the valve shall be within the relevant range given i
38、n Annex A. Valve manufacturers shall make available instructions if their specific recommendations regarding their product differ from those included in this International Standard (e.g. if their maximum torque recommendation is less than the maximum allowed in the relevant range included in Annex A
39、). For all threads, the maximum level of torque should not be exceeded as this will give rise to a high stress in the valve stem and/or cylinder neck. Care shall be taken with aluminium alloy cylinders, for which valving torques are lower than for steel cylinders. Aluminium alloy cylinders shall not
40、 be valved at temperatures above ambient because, on cooling, differential contraction between the cylinder and the valve will give rise to a high stress in the cylinder neck. High difference of temperature between cylinder neck and valve should be avoided. Some valve designs can be unsuitable to be
41、 valved at elevated temperatures (e.g. above 65 C). All tools and equipment used for valving cylinders shall be periodically validated for accuracy. Accuracy shall be established by measuring the torque applied to the valve of a valved cylinder as indicated in 5.4.3 for taper threads and in 6.5 for
42、parallel threads. NOTE Some machine tools rely on the friction between the valve and gas cylinder threads to stop the machine turning once the correct torque has been reached. For fast running machines, the inertia to be absorbed before the machine stops can result in valving torques being in practi
43、ce far higher than the machine set point. 4 Preparation 4.1 Each valve and cylinder thread shall be examined to ensure that they are to the same dimensional standard, for example ISO 11363-1 or ISO 15245-1. NOTE 1 Equivalent dimensional standards will make up the subject of the future ISO/TR 11364.
44、NOTE 2 Some standards require that valve and cylinder threads be identified by marking (e.g. ISO 10297 and ISO 13769). 4.2 The valve and cylinder threads shall be visually inspected for integrity and, where applicable, for damaged O-ring sealing surfaces. In particular, when valving aluminium alloy
45、cylinders, the bottom threads on the stem of valves and the lower threads within the cylinder neck shall be fully formed at the root of the thread and free from ragged edges or burrs. Similar care is required when fitting stainless steel valves to all cylinders. Acceptance criteria for used valves a
46、re given in ISO 22434. 4.3 Threads and sealing surface on both valve and cylinder shall be checked for cleanliness. Any remnants of old PTFE sealing tape or other sealants, paints and other contaminants shall be completely removed. Care should be taken to prevent any debris falling into the cylinder
47、. Depending on the gas service and application, before fitting the valve, it shall be ensured that the internal surface of the cylinder is clean and dry. 4.4 The top face of the cylinder, where a parallel thread is used, shall be free of paint, debris or other contamination so that the valve flange
48、can rest directly on it when the cylinder has been valved.
