BRIEF HISTORY
The IS0 Recommendation R 310, Methods of Chemical Analysis of Manganese Ores-
Determination of Hygroscopic Moisture, was drawn up by Technical Committee ISO/TC 65,
Manganese Ores, the Secretariat of which is held by the Komitet Standartov, Mer i Izme-
ritel'nyh Priborov pri Sovete Ministrov SSSR.
Work on this question by the Technical Committee began in 1954 and led, in 1957,
to the adoption of a Draft IS0 Recommendation.
In October 1958, this Draft IS0 Recommendation (No. 243) was circulated to all the
IS0 Member Bodies for enquiry. It was approved by the following Member Bodies:

Burma Ireland South Africa

Council, which decided, in July 1963, to accept it as an IS0 RECOMMENDATION.
