42、014Compressed hydrogen gas vehicle fuel containersJune 2014 2014 CSA Group11ANSI HGV 2-2014Compressedhydrogen gas vehicle fuelcontainers1 Scope1.1 GeneralThis Standard contains requirements for the material, design, manufacture, marking,and testing ofserially produced, refillable Type HGV2 container
43、s intended only for the storage of compressed hydrogengas for on-road vehicle operation. These containers:a) are to be permanently attached to the vehicle;b) have a capacity of up to 1 000 liters (35.4 ft3) water capacity; andc) have a nominal working pressure that does not exceed 70 MPa.1.2 Alterna
44、tive constructionor materialsThe construction of the containers, whether specifically covered by the various provisions of thisStandard or not, is to be in accordance with reasonable concepts of safety, performance,and durability.All specifications as to construction set forth herein are to be satis
45、fied by the construction actuallyprescribed or such other construction as will provide at least equivalent performance.1.3 Units of measurementThis standard contains SI (metric) units corresponding to the yard/pound quantities,the purpose being toallow the standard to be used in SI (metric) units. I
46、EEE/ASTM SI 10, or ISO 80000-1:2009, is used as aguide in making metric conversion from yard/pound quantities. If a value for measurement and acorresponding value in other units are stated, the first stated value is to be regarded as the requirement.The given corresponding value may be approximate.
47、If a value for a measurement and a correspondingvalue in other units are both specified as a quoted marking requirement, the first stated unit, or both areto be provided.1.4 TerminologyIn this Standard,“shall” is used to express a requirement, i.e., a provision that the user shall satisfy inorder to
48、 comply with the standard; “should” is used to express a recommendation or that which isadvised but not required; and “may” is used to express an option or that which is permissible within thelimits of the standard.Notes accompanying clauses do not include requirements or alternative requirements; t
49、he purpose of anote accompanying a clause is to separate from the text explanatory or informative material.Notes to tables and figures are considered part of the table or figure and may be written asrequirements.Annexes are designated normative (mandatory) or informative (non-mandatory)to define theirapplication.ANSI HGV 2-2014Compressed hydrogen gas vehicle fuel containersJune 2014 2014 CSA Group122 ReferencepublicationsThis Standard refers to the following publications, and where such reference is made, it shall be to theedition listed below, including al
