6、 standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internationa
7、l organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended f

14、alve 1 Scope This part of ISO 12619 specifies general requirements and definitions of compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends fuel system components, intended for use on the types of motor vehicles defined in ISO 3833. It also provides general design principles and specifi
15、es requirements for instructions and markings. It is applicable to vehicles using compressed gaseous hydrogen (CGH2) in accordance with ISO 146871 or ISO 146872 and hydrogen/natural gas blends using natural gas in accordance with ISO 154031 and ISO/TR 154032. It is not applicable to the following: a
16、) liquefied hydrogen (LH2) fuel system components located upstream of, and including, the vaporizer; b) fuel containers; c) stationary gas engines; d) container mounting hardware; e) electronic fuel management; f) refuelling receptacles. NOTE 1 It is recognized that miscellaneous components not spec
17、ifically covered herein can be examined to meet the criteria of this part of ISO 12619 and tested according to the appropriate functional tests. NOTE 2 All references to pressure in this part of ISO 12619 are to be considered gauge pressures unless otherwise specified. NOTE 3 This part of ISO 12619
18、may not apply to fuel cell vehicles in compliance with international regulations. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For unda
19、ted references, the latest edition of the referenced document (including any amendments) applies.

21、king of the component shall provide sufficient information to allow the following details to be traced: manufacturers or agents name, trademark or symbol; model designation (part number); working pressure or pressure and temperature range. The following additional markings are recommended: direction
22、 of flow (when necessary for correct installation); type of fuel; electrical ratings (if applicable); symbol of the certification agency (if applicable); type approval number; serial number or date code; reference to this International Standard (i.e. ISO 12619). Markings shall remain legible for the
23、 life of the component and shall not be removed without destroying or defacing the marking. Permanent adhesive labels are permissible, or markings may be etched, stamped, or moulded into the component. NOTE 1 Specific information required for each component can be found in ISO 126194 and subsequent
24、parts of ISO 12619. NOTE 2 This information can be provided by a suitable identification code on at least one part of the component when it consists of more than one part. 5 Construction and assembly The manual cylinder valve shall comply with the applicable provisions of ISO 126191 and ISO 126192,
