BND-4201: India’s first home-grown high purity gold reference standard launched
December 24th, 2017
India’s first home-grown high purity gold reference standard – the Bharatiya Nirdeshak Dravya (BND-4201) – was launched at the India Government Mint, Mumbai. BND-4201, which is the reference material for gold of ‘9999’ fineness (gold that is 99.99 per cent pure), will be beneficial to the consumers and public at large to ensure purity of gold. Gold reference standard is indispensable in gold and jewellery hall marking. This will also be useful for Collection and Purity Testing Centres to certify the purity of gold deposits under the gold monetisation scheme.
