| Anmerkungen | The Institute of Metrology of Bosnia and Herzegovina (IMBiH) organizes a Proficiency Testing (PT) Scheme for precious metal alloys. The scheme covers gold and silver jewellery alloys, with mass fractions ranging from 100 mg/g to 999 mg/g for both metals. The PT scheme is accredited by TÜRKAK (Turkish Accreditation Agency) under Certificate No. AB-0040-YT, in accordance with ISO/IEC 17043. Test samples are available in two formats, depending on the analytical method: wires with a diameter of 0.5 mm, intended for chemical analysis, and flat plates with dimensions of 0.5 mm × 0.5 mm, intended for X-ray fluorescence (XRF) analysis. | ||||||||||||||||||
