22、onal Standards rests with theAmerican National Standards Institute, Inc.25 West 43rd Street, Fourth FloorNew York, NY10036The American National Standards Institute (ANSI), Inc. is the nationally recognized coordinator of voluntary standards development in the United States through which voluntary or
23、ganizations, representing virtually every technical discipline and every facet of trade and commerce, organized labor and consumer interests, establish and improve the some 10,000 national consensus standards currently approved as American National Standards.ANSI provides that the interests of the p
24、ublic may have appropriate participation and representation in standardization activity, and cooperates with departments and agencies of U.S. Federal, state and local governments in achieving compatibility between government codes and standards and the voluntary standards of industry and commerce.AN
25、SI represents the interests of the United States in international nontreaty organizations such as the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). The Institute maintains close ties with regional organizations such as the Pacific Area
26、Standards Congress (PASC) and the Pan American Standards Commission (COPANT). As such, ANSI coordinates the activities involved in the U.S. participation in these groups.ANSI approval of standards is intended to verify that the principles of openness and due process have been followed in the approva
27、l procedure and that a consensus of those directly and materially affected by the standards has been achieved. ANSI coordination is intended to assist the voluntary system to ensure that national standards needs are identified and met with a set of standards that are without conflict or unnecessary
28、duplication in their requirements.PrefaceThis publication represents a standard for requirements for priority and sequencing equipment, which is part of a hydrogen gas vehicle fueling system. This standard is based on engineering principles, research and the combined expertise of manufacturers, user
29、s, 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. It is designed to allow compliance of products which may exceed that specified in the provisions herein. In its pr
30、eparation, 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 show it is necessary and desirable.CSA, does not assume or undertake to discharge any responsibility of the manufac
31、turer or any other party. CSA shall not incur any obligation or liability for damages, including consequential damages, arising out of or in connection with the use, interpretation of or reliance upon this standard.Users of this American National Standard are advised that the devices/products/activi
32、ties 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 channels. In the event of a conflict with this standard, the federal, state, or local regulations should be followed.CAUTION NOTICE:
33、 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 to reaffirm, revise or withdraw this standard no later than five (5) years from the date of approval. Purchasers of American Natio
34、nal Standards may receive current information on all standards by calling or writing the American National Standards Institute, Inc., 25 West 43rd Street, Fourth Floor, New York, N.Y. 10036, (212) 642-4900.EFFECTIVE DATE: An organization using this standard for product evaluation as a part of its ce
35、rtification program will normally establish the date by which all products certified by that organization should comply with this standard.History Of The Development Of ANSI HGV 4.5 (This History is informative and is not part of the standard.)In September 2002, CSA met with the U.S. Department of E
36、nergy, Renewable Fuels Group in Washington, D.C. to discuss standards development opportunities in the hydrogen technology 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 recogn
37、ized that an important consideration in the successful commercialization of hydrogen gas as a vehicle fuel was the issue 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 organize
38、d family of coordinated standards that addresses hydrogen gas vehicles and fueling stations.Industry and CSA recognized there was no standard that addressed requirements for priority and sequencing equipment, which is part of a hydrogen gas vehicle fueling system. The development of such a standard
39、was necessary based on industry needs and feedback: (1) There were no standards available for priority and sequencing equipment, which is part of a hydrogen gas vehicle fueling system. (2) Automotive OEMs driving the application of hydrogen as a fuel for vehicles expressed concern over solutions in
40、demonstration projects in the field. The focus of the priority and sequencing equipment standard established requirements for the performance of priority and sequencing equipment, which is part of a hydrogen gas vehicle fueling system. CSA has positioned itself as a leader in the fuel cell, hydrogen
41、 and natural gas sectors as a Standards 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
42、 of ISO TC 197 and ISO TC 22 / SC 25, 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 4.5 priority and sequencing equipment standard was proces
43、sed as an American National Standard in accordance with procedures of the American National Standards Institute (ANSI).This is the first edition of the HGV 4.5 priority and sequencing equipment standard, and was approved by the American National Standards Institute, Inc. on March 14, 2013.Previous e
