JIS M 8108:2008 Chromium, manganese and ferruginous manganese ores -- Sampling, sample preparation and determination of moisture content and size distribution
This Standard specifies the sampling method, sample preparation method, mois-
ture determination method, and particle size determination method to determine the
average qualities of chromium ores, manganese ores and ferruginous manganese ores
(hereafter referred to as "ores") of one lot.
