35、:2013-01 Introduction The purpose of this International Standard is to provide a specification for the design, manufacture, inspection and testing of a seamless aluminium alloy gas cylinder for worldwide usage. The objective is to balance design and economic efficiency against international acceptan
36、ce and universal utility. This International Standard aims to eliminate the concern about climate, duplicate inspections and restrictions currently existing because of lack of definitive International Standards. This International Standard should not be construed as reflecting on the suitability of
37、the practice of any nation or region. Following publication, this International Standard will be submitted for reference in the UN Recommendations on the Transport of Dangerous Goods Model Regulations. 5 EN ISO 7866:2012 (E) DIN EN ISO 7866:2013-01 1 Scope This International Standard specifies minim
