Preface<\/strong><\/p>\n

<\/p>\n

This is the second edition of CSA\/ANSI HGV 2, Compressed hydrogen gas vehicle fuel containers<\/em>. It supersedes the previous edition published in 2014.<\/p>\n

<\/p>\n

The major changes to this edition include the following:<\/p>\n

<\/p>\n

a) distinction between category A and B containers;<\/p>\n

<\/p>\n

b) inclusion of conformable container requirements; and<\/p>\n

<\/p>\n

c) addition of mechanical tests.<\/p>\n

<\/p>\n

CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada.<\/p>\n

<\/p>\n

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.<\/p>\n

<\/p>\n

This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.<\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1 General<\/p>\n

<\/p>\n

This Standard contains requirements for the material, design, manufacture, marking, and testing of serially produced, refillable Type HGV2 containers intended only for the storage of compressed hydrogen gas for on-road vehicle operation. These containers<\/p>\n

<\/p>\n

a) are to be permanently attached to the vehicle;<\/p>\n

<\/p>\n

b) have a capacity of up to 1000 L (35.4 ft3) water capacity; and<\/p>\n

<\/p>\n

c) have a nominal working pressure that does not exceed 70 MPa.<\/p>\n

<\/p>\n

1.2 Container type<\/p>\n

<\/p>\n

1.2.1<\/p>\n

Type HGV 2 containers are designated as follows:<\/p>\n

<\/p>\n

a) Type 1: metal;<\/p>\n

<\/p>\n

b) Type 2: resin-impregnated continuous filament with metal liner with a minimum burst pressure of 125% of service pressure. The container is hoop-wrapped;<\/p>\n

<\/p>\n

c) Type 3: resin-impregnated continuous filament with metal liner. The container is full-wrapped; and<\/p>\n

<\/p>\n

d) Type 4: resin-impregnated continuous filament with a nonmetallic liner.<\/p>\n

<\/p>\n

1.2.2<\/p>\n

Conformable container types are designated as follows:<\/p>\n

<\/p>\n

a) CT1: container or assembly of a non-axisymmetric shape without a protective shell (i.e., outside wall containing gas pressure);<\/p>\n

<\/p>\n

b) CT2: container or assembly of non-axisymmetric shape within a full or partial protective shell that is acting as a shield and not directly assisting the pressure containing elements with containing gas pressure; and<\/p>\n

<\/p>\n

c) CT3: container or assembly of non-axisymmetric shape within a conformable protective shell that is acting as a shield and directly assisting the pressure containing elements with containing gas pressure.<\/p>\n

<\/p>\n

Note: The conformable container types are an additional identifier that is used in combination with the container type. A conformable tank is designated based on the design as a Type 1 (metal) to Type 4 (resin-impregnated continuous filament with a nonmetallic liner) with the additional conformable type identifier. For example, a Type 4 CT2 container would be required to meet the criteria for a Type 4 container as well as the criteria specified for a CT2 container.<\/p>\n

<\/p>\n

1.3 Alternative construction or materials<\/p>\n

<\/p>\n

The construction of the containers, whether specifically covered by the various provisions of this Standard or not, is to be in accordance with reasonable concepts of safety, performance, and durability.<\/p>\n

<\/p>\n

All specifications as to construction set forth herein are to be satisfied by the construction actually prescribed or such other construction as will provide at least equivalent performance.<\/p>\n

<\/p>\n

1.4 Units of measurement<\/p>\n

<\/p>\n

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.<\/p>\n

<\/p>\n

1.5 Terminology<\/p>\n

<\/p>\n

In this Standard, shall is used to express a requirement, i.e., a provision that the user shall satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard.<\/p>\n

<\/p>\n

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n","protected":false},"excerpt":{"rendered":"
