19、dard.This standard is based on engineering principles, research and the combined expertise of manufacturers, users, and others having specialized experience.Nothing in this standard is to be considered in any way as indicating a measure of quality beyond compliance with the provisions it contains. I
20、t is designed to allow compliance of products which may exceed that specified in the provisions herein. In its preparation, full recognition has been given to possibilities of improvement through ingenuity of design. This standard is subject to revision as further experience and investigation may sh
21、ow it is necessary and desirable.CSA Group, does not assume or undertake to discharge any responsibility of the manufacturer or any other party. CSA Group shall not incur any obligation or liability for damages, including consequential damages, arising out of or in connection with the use, interpret
22、ation of or reliance upon this standard.Users of this American National Standard are advised that the devices, products, and activities within its scope may be subject to regulation at the federal, state, or local levels. Users are strongly urged to investigate this possibility through appropriate c
23、hannels. In the event of a conflict with this standard, the federal, state, or local regulations should be followed.CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute, Inc., require that action be taken
24、 to reaffirm, revise or withdraw this standard no later than five (5) years from the date of approval. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute, Inc., 25 West 43rd Street, Fourth Floor,
25、New York, N.Y. 10036, (212) 642-4900.EFFECTIVE DATE: An organization using this standard for product evaluation as a part of its certification program will normally establish the date by which all products certified by that organization should comply with this standard.History Of Development Of ANSI
26、/CSA HGV 4.10 (This history is informative and is not part of the standard.)NOTE: This is the first edition of ANSI HGV 4.10.In September 2002, CSA met with the U.S. Department of Energy, Renewable Fuels Group in Washington, D.C. to discuss standards development opportunities in the hydrogen technol
27、ogy area. During this meeting, DOE requested that CSA provide a proposal relating to the development of hydrogen technology standards and codes in the United States. Industry recognized that an important consideration in the successful commercialization of hydrogen gas as a vehicle fuel was the issu
28、e of codes and standards, pertaining to both fueling stations and vehicle fuel system components. CSA undertook the goal of establishing a program for the development of an organized family of coordinated standards that addresses hydrogen gas vehicles and fueling stations.Industry and CSA recognized
29、 there was no standard that addressed safety requirements for hydrogen fittings. The development of such a standard was necessary based on industry needs and feedback: (1) Conventional fitting technology used in 350 bar hydrogen applications may have technical issues when used in long term applicati
30、ons at the 700 bar level. (2) There were no standards available for piping systems for hydrogen applications at the 700 bar pressure levels. (3) Automotive OEMs driving the application of hydrogen as a fuel for vehicles expressed concern over solutions in demonstration projects in the field. The foc
31、us of the new fittings standard established performance based safety requirements for the material, design, manufacture and testing of fittings and stud ends for use with compressed gaseous hydrogen. CSA has positioned itself as a leader in the fuel cell, hydrogen and natural gas sectors as a Standa
32、rds Developing Organization (SDO). CSA is aggressively updating and developing national standards, and is playing a major role in the promulgation of US technologies nationally. As US TAG Administrator to IEC TC 105 for Fuel Cell Technologies and as US TAG members of ISO TC 197 and ISO TC 22 / SC 25
33、, CSA is facilitating US technology internationally. CSA organized committees to address technical issues in the development of standards which would affect future expansion of the hydrogen industry.The HGV 4.10 hydrogen fittings standard was processed as an American National Standard in accordance
34、with procedures of the American National Standards Institute (ANSI).This is the first edition of the HGV 4.10 hydrogen fittings standard, and was approved by the American National Standards Institute, Inc. on April 26, 2012.Previous editions of this standard are as follows:CSA America HGV 4.10-2008

If a value for a measurement and an equivalent value in other units, are both specified as a quoted marking requirement, the first stated unit, or both shall be provided.2May 2012ANSI/CSA HGV 4.10-2012 2012 CSA GroupANSI/CSA HGV 4.10-2012Performanc
45、e Of Fittings For Compressed Hydrogen Gas And Hydrogen Rich Gas Mixtures Part I: Construction1.1 Scope This standard specifies uniform methods for testing and evaluating the performance of fittings for use with compressed hydrogen gas and hydrogen rich gas mixtures. It does not address special requi
46、rements for liquid and slush hydrogen. This standard applies to hydrogen systems applications to meet current market needs. In this standard, the term “fittings” includes fittings, connectors, and stud ends for ports. This standard does not apply to stand alone components, such as:1. Quick Action co
47、uplings, (i.e., quick connects);2. Flanges; or3. Welded joints.This standard applies to newly manufactured fittings. It does not apply to fittings qualified for hydrogen service by other relevant Nationally Recognized standards or regulations such as AFNOR, BSI, CGA, JIS, etc. If the value for measu
48、rement 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.2The requirements of this standard ma
49、y be superseded by an application specific standard.The construction of parts not covered by this standard shall be in accordance with reasonable concepts of safety, substantiality and durability.All specifications as to construction set forth herein may be satisfied by the construction actually prescribed or such other construction as will provide at least equivalent performance.3May 2012Standard for fittings for compressed hydrogen 2012 CSA Group gas and hydrogen rich gas mixtures1.2 General1.2.1 Material Requirements.Materials normally in hydrogen contact shall be demonstrated
