20、ional Standard aims at the harmonization of the different operating and filling conditions of acetylene cylinder bundles and covers requirements that reflect current practice and experience regarding inspection at the time of filling. Where there is any conflict between this International Standard a
21、nd any applicable regulation, the regulation always takes precedence. In International Standards, weight is equivalent to a force, expressed in newtons. However, in common parlance (as used in terms defined in this International Standard), the word “weight” continues to be used to mean “mass”, but t
22、his practice is deprecated (see ISO 80000-4). In this International Standard the unit bar is used, due to its universal use in the field of technical gases. It should, however, be noted that bar is not an SI unit, and that the according SI unit for pressure is pascal (Pa). Pressure values given in t
23、his International Standard are given as gauge pressure (pressure exceeding atmospheric pressure) unless noted otherwise. BS EN ISO 13088:2012 ISO 13088:2011 (E)INTERNATIONAL STANDARD 1Gas cylinders Acetylene cylinder bundles Filling conditions and filling inspection 1 Scope This International Standa
24、rd specifies the minimum requirements for the filling conditions and filling inspection of acetylene cylinder bundles. It applies both to bundles which are filled while the cylinders are assembled in the bundle and to bundles of which the cylinders are filled as individual cylinders and are assemble
25、d into a bundle after filling. It does not apply to bundles containing solvent-free acetylene cylinders. This International Standard is not applicable to individual acetylene cylinders that are not intended to be assembled into a bundle (see ISO 11372). 2 Normative references The following reference

32、due to its porosity, allows the absorption of a solvent/acetylene solution NOTE The porous material may be either: monolithic, consisting of a solid product obtained by reacting materials or by materials connected together with a binder, or non-monolithic, consisting of granular, fibrous or similar

46、 or an equivalent applicable regulation/standard may be filled simultaneously without dismantling the bundle, provided that the conditions of this standard are fulfilled. Acetylene cylinders in a bundle shall have the same nominal dimensions, nominal water capacity, solvent and working pressure. Onl
47、y one porous material shall be used (covered by one type approval). This clause and Annex A apply to bundles which are filled while the cylinders are assembled in the bundle. Clause 7 applies to bundles of which the cylinders are individually filled and then assembled into a bundle. 4.2 Filling cond
48、itions 4.2.1 Maximum acetylene content The maximum acetylene content for cylinders in a bundle is specified by the manufacturer and is lower than that of individual cylinders to allow for a solvent operating range. NOTE Often the acetylene content in acetylene cylinder bundles is 90 % of that of its
49、 individual cylinders. However, other values for the maximum acetylene content of cylinders in a bundle can be used. As a result, different values for the maximum and minimum solvent content and the maximum number of consecutive fillings have to be applied (see 4.2.2, 4.2.3 and Annex A). 4.2.2 Solvent content The maximum and minimum solvent content are a function of the amount of the reduced maximum acetylene content to be used in the bundle (see 4.2.1) and the filling conditions for the individual ac
