"Copper, lead and zinc sulfide concentrates -- Determination of mass loss of bulk material on drying"
This International Standard specifies methods for the determination of moisture content of a lot of copper, lead or zinc sulfide concentrate, defined as the percentage mass loss of the moisture test portion under the conditions of drying specified in this document.
This International Standard is not applicable to drying samples used for determination of volatile elements such as mercury and sulfur. Such samples are allowed to dry at ambient temperature and a hygroscopic moisture determination is carried out in accordance with ISO 9599 at the time of chemical analysis.
