Laboratory participation in the inter-laboratory comparisons is one of the requirements of the GOST ISO/IEC 17025:2005-2009 international standard for quality assurance of the test results.
EZOCM JSC has been accredited as a proficiency testing provider of laboratory qualification validations for compliance with the ISO 17043:2010. The list of proficiency test items includes refined precious metals; alloys based on precious metals; secondary waste, mineral raw materials containing precious metals; solutions containing precious metal ions. Samples are tested for mass fraction (mass concentrations) of elements.
