Remarks:
RMMG-1 is a jarosite waste sample, the principal residue generated by the Votorantim Metais zinc plant, located in Juiz de Fora, Minas Gerais, Brazil. The raw material was oven-dried and pulverized to pass a 0,075 mm screen and then homogenized. An RMMG-1 unit consists of around 80 g of material packaged in eight vacuum sealed PET+aluminum+PE lined sachets, containing a minimum of 10 g of material each. The material sachet must be opened only for sampling. The material must not be put in contact with other chemicals in order to avoid cross contamination. The sample mass for analyses should not be less than the minimum sample size used in the material characterization. The property value and its associated uncertainty are only guaranteed if the minimum sample size is respected. Analyses should be performed on samples as received. Separate samples should be weighed before and after drying at 105 ± 2 oC to a constant weight to obtain a correction factor for moisture. The material must be stored in its original package, at room temperature in a clean and dry place. This material contains fine mineral particulate. Avoid dust dispersion, inhalation, eye contact or skin contact. Dispose of residual material in accordance with regulations pertaining for inorganic chemical and mineralogical waste.

Intended Use:
This reference material is intended for use in calibration of a measurement system, assessment of a measurement procedure, quality control and value assignment to materials with similar matrices.
