Scope
WARNING: Personnel using this standard should have practical experience in formal laboratory work. This standard does not address all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This standard specifies the determination of sulfide content by iodometric method. This standard is applicable to the determination of sulfide content in fluorite, and the measurement range is: mass fraction ωs (%)≥0.001% (sulfide is calculated as sulfur). This standard does not apply to the determination of polysulfides contained in samples.
