Interim Corrosion Test Method for Gas Furnaces and Vents. Topical Report, January1988-January 1991

摘要

An accelerated corrosion test method is being developed in response to anindustry need for a method to evaluate the expected long-term corrosion resistance of high-efficiency gas-fired appliances. The test conditions specified are realistic, yet severe enough to yield definitive corrosion results in a relatively short test period of about 100 days. The method is suitable for accelerated corrosion tests on residential-sized gas-fired appliances and vents. The test method described in the report is based on several years of related research at Battelle and A.G.A. Laboratories, plus review comments received from manufacturers on two interim reports, dated May 1988 and February 1989. The report also suggests an application of the test method for gas-fired boilers, water heaters, and combination space/water heaters. To verify the corrosion test method, a considerable amount of testing has been accomplished using actual furnaces and vents, and work is continuing to select the final accelerated test conditions. Additional validation work is needed on its application to boilers, water heaters, and combination heaters. As more experience is gained using the test method, additional refinements may be made.
