Compressed hydrogen gas vehicle fuel containers
Preface This is the second edition of CSA/ANSI HGV 2, Compressed hydrogen gas vehicle fuel containers . It supersedes the previous edition published in 2014. The major changes to this edition include the following: a) distinction between category A and B containers; b) inclusion of conformable container requirements; and c) addition of mechanical tests. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada. 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. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Scope 1.1 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. 1.2 Container type 1.2.1 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. 1.2.2 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. 1.3 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. 1.4 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. 1.5 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.

Test methods for evaluating material compatibility in compressed hydrogen applications - Metals
Preface This is the first edition of ANSI/CSA CHMC 1-2014, Test methods for evaluating material compatibility in compressed hydrogen applications - Metals. It supersedes the previous CSA CHMC 1-2012 edition published in 2012. Scope This standard provides uniform test methods for evaluating material compatibility with compressed hydrogen applications. The results of these tests are intended to provide a basic comparison of materials performance in applications utilizing compressed hydrogen. This standard is not intended to replace sound engineering judgment; additional testing considerations may be necessary to fully qualify the design of a component manufactured for use in certain hydrogen applications. This standard applies to metallic materials only. If the value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification. All references to pressure throughout this standard are to be considered gauge pressures, unless otherwise specified.

Fuel cell technologies - Part 3-100: Stationary fuel cell power systems - Safety (Adopted IEC 62282-3-100:12, first edition, 2012-02 with U.S. deviations)
Preface This is the first edition of ANSI/CSA FC-1:2014, Fuel cell technologies - Part 3-100: Stationary fuel cell power systems - Safety, which is an adoption with U.S. deviations of the identically titled IEC (International Electrotechnical Commission) Standard 62282-3-100 (first edition, 2012-02). It supersedes the previous edition of ANSI FC-1 published in 2012. The U.S. deviations are intended to a) correct inaccuracies; b) replace references to IEC Standards with references to U.S. and CSA Standards, where applicable. Scope This part of IEC 62282 applies to stationary packaged, self-contained fuel cell power systems or fuel cell power systems comprised of factory matched packages of integrated systems which generate electricity through electrochemical reactions. This standard applies to systems - intended for electrical connection to mains direct, or with a transfer switch, or to a standalone power distribution system; - intended to provide AC or DC power; - with or without the ability to recover useful heat; - intended for operation on the following input fuels a) natural gas and other methane rich gases derived from renewable (biomass) or fossil fuel sources, for example, landfill gas, digester gas, coal mine gas; b) fuels derived from oil refining, for example, diesel, gasoline, kerosene, liquefied petroleum gases such as propane and butane; c) alcohols, esters, ethers, aldehydes, ketones, Fischer-Tropsch liquids and other suitable hydrogen-rich organic compounds derived from renewable (biomass) or fossil fuel sources, for example, methanol, ethanol, di-methyl ether, biodiesel; d) hydrogen, gaseous mixtures containing hydrogen gas, for example, synthesis gas, town gas. This standard does not cover: - micro fuel cell power systems; - portable fuel cell power systems; - propulsion fuel cell power systems. NOTE For special application such as ""marine auxiliary power"", additional requirements may be given by the relevant marine ship register standard. This standard is applicable to stationary fuel cell power systems intended for indoor and outdoor commercial, industrial and residential use in non-hazardous (unclassified) areas. This standard contemplates all significant hazards, hazardous situations and events, with the exception of those associated with environmental compatibility (installation conditions), relevant to fuel cell power systems, when they are used as intended and under the conditions foreseen by the manufacturer. This standard deals with conditions that can yield hazards on the one hand to persons, and on the other to damage outside the fuel cell system only. Protection against damage to the fuel cell system internals is not addressed in this standard, provided it does not lead to hazards outside the fuel cell system. The requirements of this standard are not intended to constrain innovation. When considering fuels, materials, designs or constructions not specifically dealt with in this standard, these alternatives shall be evaluated as to their ability to yield levels of safety and performance equivalent to those prescribed by this standard.
