45、tovesNote: 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 harmonization of the United States and Canadian safety standardsaddressing gas-fired equipm

It was believedthat the elimination of the differences between the standards would remove potential trade barriersand provide an atmosphere in which North American manufacturers could market more freely in theUnited States and Canada. The

47、 harmonization of these standards was also seen as a step towardharmonization with international standards.The draft harmonized standard was based on current coverage from the American National Standardfor Portable Camp Cook Stoves for Use with Propane Gas, Z21.72-1982, and the Canadian Standard for

48、Portable Type Gas Camp Stoves, CAN1-11.2-M79. On September 19, 1997, the Z21/(Interim CSA) JointGas Refrigerators and Portable Camping Equipment Subcommittee reviewed by letter ballot the firstdraft harmonized portable type gas camp stoves standard. At its February 5, 1998 meeting, in light ofcommen

49、ts received, the joint subcommittee agreed to adopt the revised draft standard for publicreview and comment. The revised draft portable type gas camp stoves standard was distributed for anindustrial review during June 1998.At its November 1998 meeting, the subcommittee assigned a task group to review the commentsreceived and to revise the draft standard. At its June 1999 meeting, the joint subcommittee reviewedthe revised draft standard prepared by the camping equipment task group and agreed to distributesubstantive changes to the camp stov
