Which purity grades of silver are covered by the BIS Silver Refinery Scheme announced on World Standards Day 2026?
- A.995.0, 990.0 and 985.0 parts per thousand
- B.999.9, 999.5 and 999.0 parts per thousand
- C.916, 875 and 750 parts per thousand
- D.999.99 and 999.95 parts per thousand only
Correct answer
Explanation
The correct answer is 999.9, 999.5 and 999.0 parts per thousand. These three grades of fine silver bullion and coins were brought within the scope of the standard after the gazette notification of Amendment No. 1 to IS 2112:2025, which deals with silver and silver alloys, jewellery and artefacts, their fineness and their marking. Under the scheme BIS grants a licence to a refinery or a mint after assessing its technical competence, refining process and testing infrastructure, and the licensed facility may then apply the official hallmark. A hallmarked piece carries the BIS Standard Mark, the word SILVER, the purity grade, the manufacturer mark and a serial number for batch traceability. Option A is wrong because those figures do not appear in the amended scope. Option C is wrong because 916 and 750 are familiar gold fineness grades for 22 carat and 18 carat jewellery, not the silver bullion grades in this scheme. Option D is wrong because three grades were notified, not two, and the scheme is modelled on the existing Gold Refinery Scheme.
