- Scope
- This standard specifies the method for the determination of trace amounts of sulfur in styrene for industrial use. This standard applies to the determination of trace amounts of sulfur in styrene for industrial use. The measuring range is 0.5～100mg/kg. After dilution, this method can also be used for the determination of higher sulfur content.
