37、before, during and after filling of composite cylinders (Types 2 to 5 inclusive).DIN EN ISO 24431:2017-07 EN ISO 24431:2016 (E) 4 IntroductionThis International Standard covers requirements that reflect current practice and experience.Each transportable gas cylinder is inspected at the time of filli
38、ng in order to establish that it has no defects which render it unsafe for filling or continued use, it can be identified and complies with the relevant requirements with regard to marking (e.g. within test period, labelling, colour coding and completeness of its accessories), and its valve function
39、s satisfactorily.The cylinder filling inspection is carried out exclusively by persons who have the appropriate training and competencies, so as to ensure that each cylinder is safe for continued use.Guidance and requirements provided in this International Standard allow fillers to determine when cy
40、linders should be rejected for filling. This International Standard is intended to be used as a basis for developing specific operating procedures for a filling operation.CAUTION Some of the tests specified in this International Standard involve the use of processes which could lead to a hazardous s
41、ituation.This International Standard is intended to be used under a variety of national regulatory regimes, but has been written so that it is suitable for the application of the UN Model Regulations.1Attention is drawn to requirements in the relevant national regulations of the country (countries)
42、where the cylinders are intended to be used that might override the requirements given in this International Standard. Where there is any conflict between this International Standard and any applicable regulation, the regulation always takes precedence.In International Standards, weight is equivalen
43、t 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”, although this practice is deprecated (see ISO 80000-4).DIN EN ISO 24431:2017-07 EN ISO 24431:2016 (E) 5 1 ScopeThis Intern
44、ational Standard specifies the inspection requirements at the time of filling, and applies to seamless or welded transportable gas cylinders made of steel or aluminium-alloy (Type 1), and for composite transportable gas cylinders (Types 2 to 5 inclusive) for liquefied or compressed gases of a water
45、capacity up to 150 l. It may be applicable to cylinders and tubes with a water capacity between 150 l and 450 l, provided they are inspected and filled as individual cylinders and tubes.This International Standard does not apply to acetylene cylinders, bundles of cylinders, tubes, multiple-element g
46、as container (MEGCs) or battery vehicles.This International Standard may also be applicable to LPG. For specific LPG applications, refer to ISO 10691.For cylinders manifolded in bundles, refer to ISO 11755.2 Normative referencesThe following documents, in whole or in part, are normatively referenced
