45、p12History of the development of the standard for connectors for outdoorgas appliances and manufactured homesNote: 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

46、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 differences between the standards would remove potential trade barriersand provide an atmos

The harmonization of these standards was also seen as a step towardharmonization with international standards.A draft harmonized standard for connectors for outdoor appliances and manufactured homes

On September 15, 1998, the Z21/CSA JointSubcommittee on Connectors for Gas Appliances reviewed, by letter ballot, the first draft harmonizedconnectors for outdoor appliances and manufactured homes standard based on current coverage fromthe Ameri

At its July 14, 1999 meeting, following reconsideration andmodifications in light of comments received on the
