46、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 equipment for res

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 harmonizat

Joint subcommittees were established to facilitate thestandards harmonization process between the United States and Canada.The draft harmonized standard for Gas Convenience Outlets and Optional Enclosure
