Purity Certification Testing for Gold and Silver Bullion

The demand for purity certification testing in gold and silver bullion has grown significantly with the rise of precious metals trading, both in physical form and through financial derivatives. This service is critical for ensuring that the materials meet the required standards set by industry bodies such as ISO 4358:1996 for gold and ISO 2717-1:2007 for silver.

The process involves a series of rigorous tests to verify the purity levels, typically expressed in parts per thousand (ppm) or carats. For gold bullion, the most common purity levels are 999.9 (four nines), 995 (five nines), and 990 (six nines). Silver bullion is often tested for 999 (four nines) or 925 sterling silver.

The testing method typically involves the following steps:

Initial visual inspection of the sample to check for any obvious contamination or defects.
Cleaning and preparation of the sample, which may involve melting down small samples into a homogeneous form suitable for analysis.
Use of advanced spectroscopy techniques such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to measure trace elements that affect purity.

The results are reported in terms of the percentage of pure gold or silver, along with any impurities present. These tests ensure that the bullion meets industry standards and can be trusted for use in manufacturing or trading.

For quality managers and compliance officers, purity certification testing is a cornerstone of ensuring product integrity and meeting regulatory requirements. R&D engineers benefit from this service by having access to accurate data on material composition which they can use to refine processes and formulations. Procurement teams can leverage these tests to verify the authenticity and value of purchased bullion.
