Additional requirements on materials for some

31、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 following referenced documents are indispensable for the application of this document. For dated r

32、eferences, 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 testing Specifications 3 General requirements Materials liable to come into contact with the proc

33、ess gases shall be resistant to the chemical, mechanical and thermal action of these gases under all operating conditions (see for example ISO 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 t

34、emperature range of 20 C to +60 C. Where dissimilar materials are in direct contact, steps shall be taken to prevent corrosion. 4 Specific requirements 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,

35、the copper content of materials liable to come into contact with such gases shall not exceed 70 % (mass fraction). The manufacturer shall not use any procedure resulting in copper enrichment of the surface. Nozzles and necks of blowpipes are an exception to this requirement. NOTE International and n

36、ational regulations may require different maximum copper contents than those specified here, but these remain generally within this range. The likelihood of the formation of copper acetylides depends on metallic corrosion and contamination which can be caused by many factors, e.g. moisture. 4 DIN EN

37、 ISO 9539:2014-04 EN ISO 9539:2010 + A1:2013 (E) !ISO 1817, Rubber, vulcanized or thermoplastic Determination of the effect of liquids“ Metal flame-arresting elements (including sintered metal elements) shall be manufactured from copper-free materials. Where brazing alloys containing silver and copp

38、er are used, the silver content shall not exceed 46 % (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 brazi

39、ng alloy will be small and all residues of flux will 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 vio

40、lently in pure oxygen, and many materials that do not 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 adia

41、batic compression produced when oxygen at high pressure 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 washe

42、rs for pressure gauges. Materials for filters whose surfaces 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 par

43、ts liable to come into contact with oxygen shall be made 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 hydr

44、ocarbon contamination levels: a) for applications in 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

45、 method of manufacture or an appropriate cleaning procedure. 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-me

46、tallic materials 4.2.1 Resistance to solvents for non-metallic materials in contact with fuel gases 5 DIN EN ISO 9539:2014-04 EN ISO 9539:2010 + A1:2013 (E) !Non-metallic materials (e.g. those used for seals and lubricants) liable to come into contact with acetylene shall be adequately resistant ind

47、ividually to acetone and dimethylformamide (DMF) solvents. Non-metallic materials (e.g. those used for seals and lubricants) liable to come into contact with propane, butane and methylacetylene-propadiene mixtures shall be adequately resistant to n-pentane. For the purposes of this International Sta

48、ndard, the term “adequate resistance” (to solvents) will be taken to mean that the material shall fulfil the following conditions. 4.2.2 Resistance to oxygen 4.2.2.1 Resistance to ignition Ignition resistance in oxygen of non-metallic materials and lubricants shall have been established by an appropriate test procedure. NOTE This test is described in several standards, e.g. ISO 11114-3. 4.2.2.2 Resistance to ageing Non-metallic sealing materials for use with air and oxygen shall be capable of withstan
