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 standards addressing gas-fired equipment for residential, commercial and industrial applications. It was believed that the elimination of the differences between the standards would remove potential trade barriers and provide an atmosphere in which North American manufacturers could market more freely in the United States and Canada. The harmonization of these standards was also seen as a step toward harmonization with international standards.
With the formation of joint subcommittees, a Canadian Gas Association Standards Steering Committee on Gas Burning Appliances and Related Accessories was established to parallel Accredited Standards Committees Z21 and Z83, and to support the formation of joint subcommittees. Operating procedures, in accordance with American National Standards Institute procedures, for joint subcommittees were developed and subsequently approved by ANSI on April 1, 1993.
At its September 23-24, 1992 meeting, the Joint Thermostat and Automatic Gas lgntion Systems Subcommittee adopted ANSI Z21.77 for distribution for review and comment as a harmonized standard, in that a comparable Canadian standard did not exist. The first draft harmonized manually operated piezo-electric spark gas ignition systems and components standard was distributed for review and
comment during March 1994.
Following reconsideration and modification of the proposed harmonized draft standard for manually operated piezo-electric spark gas ignition systems and components, in light of comments received, the joint thermostat and automatic gas ignition systems subcommittee, at its July 14, 1994 meeting, recommended the proposed standard to the Z21 Committee and the CGA Standards Steering
Committee, for approval.
1.5.1 Frames and mounting brackets of devices intended to be exposed to combustion chamber temperatures shall be constructed of material having a melting point of not less than 1 450°F (788°C).
1.5.2 The manufacturer shall supply evidence acceptable to the testing agency that all materials have been evaluated and found to be suitable for their intended usage. Test data based on ASTM or other appropriate test procedures, certifications or historical data may be used for this purpose. The evidence shall show that the materials have been evaluated, as appropriate, for resistance to moisture, corrosion and the effects of fuel gases, including the sulfur compounds therein, and that seal materials are resistant to the effects of ozone.CSA 6.23 pdf download.
