Precious Metals Sectional Committee, MTD 10

FOREWORD
This Indian Standard (Fourth Revision) was adopted by Bureau of Indian Standards, after the draft finalized by
the Precious Metals Sectional Committee had been approved by the Metallurgical Engineering Division Council.
This standard was first published in 1959 and subsequently revised in 1971, 1981 and 1999. In many advanced
countries, the gold ornaments/artefacts traded are certified for purity and are marked with various details like
purity/fineness of the ornament, manufacturer’s mark, the mark of the assaying laboratory responsible for certifying
the purity, etc. These ornaments/artefacts are termed as Hallmarked.
This standard is primarily meant to classify the various grades of gold according to their gold content and provide
guidelines to mark the gold articles. The percentage of alloying elements stipulated for various grades depend
upon their specific uses and the detailed compositions of these grades have been covered in IS 2790 : 1999
‘Guidelines for manufacture of 23, 22, 21, 18, 14 and 9 carat gold alloys (second revision)’.
In this revision, bullion and coin have been defined and included in the scope of the standard and marking clause
has been suitably modified, the grades of fineness 958(23k), 875(21k), 833 (20k), 791(19k), 708(17k),
666(16k) and 375(9k) have been deleted in consumer welfare, and a negative tolerance of maximum 2ppt has
been introduced on re-testing of hallmarked jewellery/artefact.
Assistance hasbeen derived from International Standard ISO 9202 : 2014 ‘Jewellery — Fineness of precious
metal alloys’, issued by the International Organization for Standardization.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
IS 2 : 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in the
rounded off value should be the same as that of the specified value in this standard.
