40、the time of manufacture for worldwide usage. The objective is to balance design and economic efficiency against international acceptance and universal utility.This International Standard aims to eliminate concern about climate, duplicate inspections and restrictions currently existing because of lac

41、k of definitive International Standards. It does not reflect on the suitability of the practice of any nation or region.This International Standard addresses the general requirements on design, construction and initial inspection and testing of pressure receptacles of the United Nations Recommendati

42、ons on the Transport of Dangerous Goods: Model Regulations.It is intended to be used under a variety of regulatory regimes, but it is suitable for use with the conformity assessment system for UN pressure receptacles of the above-mentioned Model Regulations.DIN EN ISO 11120:2015-05EN ISO 11120:2015

43、(E)51 ScopeThis International Standard specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examinations and tests at manufacture of refillable quenched and tempered seamless steel tubes of water capacities exceeding 150 l up to and includin

44、g 3 000 l for compressed and liquefied gases exposed to extreme world-wide ambient temperatures, normally between 50 C and +65 C.This International Standard is applicable to tubes with a maximum tensile strength, Rma, of less than 1 100 MPa. These tubes can be used alone or in batteries to equip tra

45、ilers or multiple element gas containers (ISO modules or skids) for the transportation and distribution of compressed gases.This International Standard is applicable to tubes having an opening at each end.2 Normative referencesThe following documents, in whole or in part, are normatively referenced
