30、y of developmentof the standard for gas hose connectorsforportableoutdoor gas-fired appliancesNote: This History is informative and is not part of the standard.With the onset of the Free Trade agreement between the United States and Canada on January 2, 1988,significant attention was given to the ha

31、rmonization of the United States and Canadian safety standardsaddressing gas-fired equipment for residential, commercial and industrial applications. It was believedthat the elimination of the differences between the standards would remove potential trade barriers andprovide an atmosphere in which N

32、orth American manufacturers could market more freely in the UnitedStates and Canada. The harmonization of these standards was also seen as a preliminary step towardharmonization with international standards.With the formation of joint subcommittees a Canadian Gas Association Standards Steering Commi

33、ttee onGas Burning Appliances and Related Accessorieswas established to parallel and to support the formationof joint subcommittees. Operating procedures, in accordance with American National Standards Instituteprocedures, for joint subcommittees were developed and subsequently approved by ANSI on A

34、pril 1,1993.A draft harmonized standard for Gas Hose Connectors for Portable Outdoor Gas-Fired Appliances,ANSIZ21.54, was prepared during 1993. At its September 23-24, 1993 meeting,the Joint Subcommittee onStandards for Gas Appliance Connectors adopted the first draft harmonized standard for gas hos

35、econnectors for distribution for review and comment during August 1994.Following reconsideration and modification of the proposed draft standard for gas hose connectors inlight of comments received, the joint connector subcommittee, at its September 20, 1994 meeting,recommended the proposed fourth d

36、raft to the Z21 Committee and the CGA Standards SteeringCommittee for approval.The proposed draft of the harmonized standard for gas hose connectors was approved by the Z21Committee at its April 1995 meeting. The CGA Standards Steering Committee approved the proposeddraft harmonized standard for gas

37、 hose connectors by letter ballot dated May 19, 1995.The first edition of the harmonized Z21/CGA standard for Gas Hose Connectors for Portable Outdoor Gas-Fired Appliances was approved by the CGA Standards Advisory Committee and the CanadianInterprovincial Gas Advisory Council on July 1,1995 and by

38、the American National Standards Institute,Inc., on July 16, 1996.The previous editions of the gas hose connectors for portable outdoor gas-fired appliances,and addendathereto, approved by the Interprovincial Gas Advisory Council and American National Standards Institute,Inc. are as follows:Z21.54-20

41、s to gas hose connectors (See Clause 3 Definitions), hereinafter referred to asconnectors. They are conduits for conveying gas and depend for gas-tightness on the wall structure ofthe hose material. Such connectors shall be:a) newly produced and constructed entirely of new, unused parts and material

42、s; andb) equipped with a fitting at each end provided with standard taper pipe threads.1.2Connectors covered by this Standard are intended for:a) connection of portable outdoor gas-fired appliancesto the gas supply piping;b) use in unconcealed outdoor locations;c) use only in locations where they wi

43、ll not be likely to be subject to excessive temperatures above200F (93.5C);d) use with natural gas , manufactured gas, mixed gases, propane and LP gas-air mixtures; ande) use on gas piping systems having fuel gas pressures not in excess of 1/2 psi (3.45 kPa).1.3All references to psi throughout this

44、Standard are to be considered gauge pressure unless otherwisespecified.1.4Annex A contains provisions that are unique to Canada.1.5Clause 2 contains a list of standards specifically referenced in this Standard and sources from which thesereference standards may be obtained.1.6This Standard contains

45、SI (Metric) equivalents to the yard/pound quantities,the purpose being to allowthe standard to be used in SI (Metric) units. (IEEE/ASTM-SI-10 is used as a guide in making metricconversion from yard/pound quantities.) If a value for a measurement and an equivalent value in otherunits, the first state

46、d is to be regarded as the requirement. The given equivalent value may beapproximate. If a value for a measurement and an equivalent value in other units, are both specified as aquoted marking requirement, the first stated unit, or both shall be provided.1.7In this Standard,“shall” is used to expres

47、s a requirement, i.e., a provision that the user shall satisfy inorder to comply with the standard; “should” is used to express a recommendation or that which isANSI Z21.54-2014 CSA 8.4-2014Gas hose connectors for portable outdoor gas-fired appliancesJune 2014 2014 CSA Group14advised but not require
