Canadian observations on the proposed ISO/TC 102/SC 3 method for measuring the relative reducibility of natural and processed iron ores [electronic resource] / D.A. Reeve and J.H. Walsh, Metals Reduction and Energy Centre. Ottawa : Information Canada, 1972. iii, 14 p. : charts, ill. Technical bulletin ; TB 144 Cover title. "January 1972." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references (p. 7). “At the Fifth International Meeting of ISO/TC 102/SC 3 held in Ottawa, September 21-25, 1970, the Second Draft ISO Proposal for a method for measuring the relative reducibility of natural and processed iron ores (Document 174E) was agreed upon by the attending delegates. Following that meeting, the Canadian Advisory Committee to ISO/TC 102 decided that Canada should have a more active participation in development of the reducibility test than before. Consequently, in February 1971, assembly began of a reducibility test apparatus at the Metals Reduction and Energy Centre of the Mines Branch in Ottawa. After construction and testing of the apparatus had been completed, a series of tests was carried out to investigate several of the parameters which might influence the behaviour of iron ores under high-temperature reducing conditions and which might affect the reproducibility of the test method. The present report summarizes the results of this series of tests and attempts to point out areas of the test method which may lead to ambiguous and unreliable reducibility data. It is felt that these areas are worthy of more clarification in the next draft ISO proposal for a method of measuring the relative reducibility of natural and processed iron ores"--Introd., p. 1.
