- Scope
- This standard specifies the test principles, reagents, instruments, test procedures, result calculation and precision for the determination of total sulfur content in tea by nickel reduction-volume titration method. This standard is applicable to the determination of total sulfur content in refined naphthalene, industrial naphthalene and pressed naphthalene. This method is directly applicable to samples with total sulfur content of 30~10000mg/kg. When the total sulfur content is higher, the dilution method can be used to determine it.
