The Canadian Standards Association (CSA), under whose auspices this Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-profit, nonstatutory, voluntary membership a
27、ssociation engaged in standards development and certification activities. Les normes CSA refltent le consensus de producteurs et dusagers de partout au pays, au nombre desquels se trouvent des fabricants, des consommateurs, des dtaillants et des reprsentants de syndicats, de corps professionnels et
28、dagences gouvernementales. Lutilisation des normes CSA est trs rpandue dans lindustrie et le commerce, et leur adoption divers ordres de lgislation, tant municipal et provincial que fdral, est chose courante, particulirement dans les domaines de la sant, de la scurit, du btiment, de la construction
29、et de lenvironnement. CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial,
30、and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Commit
31、tee work and supporting the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen.

41、 Standards Institute The American National Standards Institute (ANSI), Inc. is the nationally recognized coordinator of voluntary standards development in the United States through which voluntary organizations, representing virtually every technical discipline and every facet of trade and commerce,
42、 organized labor and consumer interests, establish and improve the some 8500 national consensus standards currently approved as American National Standards. ANSI provides that the interests of the public may have appropriate participation and representation in standardization activity, and cooperate
43、s 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. ANSI represents the interests of the United States in international nontreaty organizations such as the
44、 International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). The Institute maintains close ties with regional organizations such as the Pacific Area Standards Congress (PASC) and the Pan American Standards Commission (COPANT). As such, ANSI coordinat
45、es 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 approval procedure and that a consensus of those directly and materially affected by the standards has been
46、 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 duplication in their requirements. Responsibility of approving American National Standards rests wit

It is the result of years of experience i
48、n the manufacture, testing, installation, maintenance, inspection and research on cylinder connection devices designed for utilization of gas. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this
49、 standard are intended to help reduce such risks while retaining the normal operation of the appliance. 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 cylinder connection devices, the safety construction and performance of which may exceed the various provisions specified herein. In its preparation, full recognition has been give
