AS 2140:2008 (R2021) PDF Download

The standards for the composition and labelling of precious metal items, notably those used in the creation of jewellery, are outlined in the AS 2140:2008 (R2021) standard. The standard strives to guarantee that precious metal jewellery keeps its level of quality and purity constant.

The standard outlines the standards for the fineness of precious metal alloys used in jewellery, guaranteeing that the alloys have the necessary percentage of precious metals. It offers guidelines on the compositional variances of these alloys that can be tolerated while still maintaining their desirable attributes.

The standard also specifies the information that must be permanently engraved or stamped on the items to identify their fineness when it comes to precious metal marking standards. Customers may clearly see from this designation the quality and purity of the precious metal used in the jewellery they are buying.

Due to its concentration on jewellery and ensuring that it complies with the outlined fineness criteria, it is vital to note that this standard does not apply to items created for industrial reasons.
