General

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

a) are to be permanently attached to the vehicle;

b) have a capacity of up to 1000 L (35.4 ft3) water capacity; and

c) have a nominal working pressure that does not exceed 70 MPa.

Container type

Type HGV 2 containers are designated as follows:

a) Type 1: metal;

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;

c) Type 3: resin-impregnated continuous filament with metal liner. The container is full-wrapped; and

d) Type 4: resin-impregnated continuous filament with a nonmetallic liner.

Conformable container types are designated as follows:

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

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

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.

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.

Alternative construction or materials

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.

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.

Units of measurement

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.

Terminology

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.

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.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
