22、RD ISO 9539:2010(E) ISO 2010 All rights reserved 1Gas welding equipment Materials for equipment used in gas welding, cutting and allied processes 1 Scope This International Standard specifies the general, and some of the special, requirements on materials used for the construction of equipment used
23、in gas welding, cutting and allied processes. Additional requirements on materials for some equipment are given in other standards. This International Standard is not applicable to materials used for the construction of welding hoses which are specified in ISO 3821. 2 Normative references The follow
24、ing 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 554, Standard atmospheres for conditioning and/or testi
25、ng Specifications ISO 1817, Rubber, vulcanized Determination of the effect of liquids 3 General requirements Materials liable to come into contact with the process gases shall be resistant to the chemical, mechanical and thermal action of these gases under all operating conditions (see for example I
26、SO 11114-1 and ISO 11114-2). The properties of the materials shall be such that the function for which they are intended can be performed correctly within the temperature range of 20 C to +60 C. Where dissimilar materials are in direct contact, steps shall be taken to prevent corrosion. 4 Specific r
27、equirements 4.1 Metallic materials 4.1.1 For use with acetylene and gases with similar chemical properties Because of the risk of forming explosive acetylides, the copper content of materials liable to come into contact with such gases shall not exceed 70 % (mass fraction). The manufacturer shall no
28、t use any procedure resulting in copper enrichment of the surface. Nozzles and necks of blowpipes are an exception to this requirement. NOTE International and national regulations may require different maximum copper contents than those specified here, but these remain generally within this range. T
29、he likelihood of the formation of copper acetylides depends on metallic corrosion and contamination which can be caused by many factors, e.g. moisture. ISO 9539:2010+A1:2013 (E)BS EN ISO 9539:2010+A1:2013 ISO 2010 All rights reservedISO 1817, Rubber, vulcanized or thermoplastic Determination of the
30、effect of liquidsBS EN ISO 9539:2010ISO 9539:2010(E) 2 ISO 2010 All rights reservedMetal flame-arresting elements (including sintered metal elements) shall be manufactured from copper-free materials. Where brazing alloys containing silver and copper are used, the silver content shall not exceed 46 %
31、 (mass fraction) and the copper content shall not exceed 37 % (mass fraction). The brazing connection shall be designed and completed in such a way that, as far as practicable, the area where acetylene is liable to come into contact with the brazing alloy will be small and all residues of flux will
32、be removed. 4.1.2 For use with oxygen Metallic materials for components intended to be used with oxygen shall be selected according to their resistance to ignition and the release of ignition energy. NOTE 1 Materials that burn in air will burn violently in pure oxygen, and many materials that do not
33、 burn in air will do so in pure oxygen, particularly under pressure. Similarly, materials that can be ignited in air require less energy to ignite in oxygen. Many such materials can be ignited by friction at a valve seat or stem packing or by adiabatic compression produced when oxygen at high pressu
34、re is rapidly introduced into a system initially at low pressure. Aluminium or aluminium alloys shall not be used for components whose surfaces come into contact with oxygen at a working pressure greater than 30 bar, except aluminium sealing washers for pressure gauges. Materials for filters whose s
35、urfaces come into contact with gas at cylinder pressure shall be non-inflammable under the conditions of use. The selection of the material of the filter is particularly important to reduce the probability of ignition. Springs and other moving parts liable to come into contact with oxygen shall be m
36、ade of materials that resist oxidation and they shall not be coated. NOTE 2 Plating could come off. All components in contact with oxygen shall be subjected to appropriate cleaning procedures so that their surfaces do not exceed the following hydrocarbon contamination levels: a) for applications in
37、the pressure range of 50 kPa to 3 000 kPa: no greater than 550 mg/m2; b) for applications at a pressure greater than 3 000 kPa: no greater than 220 mg/m2and no particles of size 100 m. These requirements shall be met by using either an appropriate method of manufacture or an appropriate cleaning pro
38、cedure. Compliance shall be checked either by verification of the cleanliness of the components or by validation of the cleaning procedure or the manufacturing process. NOTE 3 ISO 15001 provides guidance on suitable cleaning procedures. 4.2 Non-metallic materials 4.2.1 Resistance to solvents for non
39、-metallic materials in contact with fuel gases Non-metallic materials (e.g. those used for seals and lubricants) liable to come into contact with acetylene shall be adequately resistant to the solvents acetone and dimethylformamide (DMF). Non-metallic materials (e.g. those used for seals and lubrica
40、nts) liable to come into contact with propane, butane and methylacetylene-propadiene mixtures shall be adequately resistant to n-pentane.
