38、eement between the United States and Canada on January 2, 1988,significant attention was given to the harmonization of the United States and Canadian safety standardsaddressing gas-fired equipment for residential, commercial and industrial applications. It was believedthat the elimination of the dif

39、ferences between the standards would remove potential trade barriers andprovide an atmosphere in which North American manufacturers could market more freely in the UnitedStates and Canada. The harmonization of these standards was also seen as a step toward harmonizationwith international standards.

40、Joint subcommittees were established to facilitate the standardsharmonization process between the United States and Canada.The draft harmonized standard was based on current coverage from the American National Standard forRefrigerators Using Gas Fuel, Z21.19-1990,and the Canadian Gas Association Sta

41、ndard for RefrigeratorsUsing Gas Fuel, CGA 1.4-M94. At the November 45, 1998 meeting of the (Interim CSA)/Z21 JointSubcommittee for Gas Refrigerators and Portable Camping Equipment, the subcommittee adopted thechanges to the proposed draft Harmonized Standard for Refrigerators Using Gas Fuel, ANSI Z

42、21.19 CSA 1.4 dated October 23, 1998 and approved the updated draft for distribution for Public Review andComment. The new proposed draft harmonized standard (Draft #2) was distributed for Review andComment on January 5, 1999.At the June 23-23, 1999 joint subcommittee meeting in Atlanta, GA, the sub

43、committee adopted theproposed draft harmonized standard with editorial changes (Draft #3) for submittal to the parentcommittees for their approval. The letter ballot #99-31 was “approved, pending disposition of negativecomments.” At its June 2000 meeting,the joint subcommittee reviewed the revised d

44、raft standardprepared by the refrigerators task group and adopted the revised Draft #4 for distribution for industryreview. Draft #4 was distributed for another industry review during September 2000.At its February 2001 meeting, following reconsideration and modifications of the proposed draftstanda

45、rd for refrigerators using gas fuel, the joint subcommittee recommended the proposed draftstandard to the Accredited Standards Committee Z21/83 and the CSA Technical Committee for approval.The proposed draft of the harmonized standard for Refrigerators Using Gas Fuel was approved by theZ21/83 Commit

46、tee on January 10, 2002, and by the CSA Technical Committee by letter ballot datedApril 3, 2001.The first edition of the harmonized Z21/83 CSA Standard for Refrigerators Using Gas Fuel was approvedby the Canadian Interprovincial Gas Advisory Council on November 14, 2001 and by the AmericanNational S

47、tandards Institute, Inc., on January 14, 2002.Following the procedures outlined above, further revisions to this standard, Z21.19 CSA 1.4, were madein line with industry developments.
