Scope: This standard specifies the requirements for the detection and analysis techniques and detection processes of jadeite origin (abbreviated as "origin"). This standard applies to relevant enterprises and institutions engaged in jadeite origin certification, identification, and the provision of origin tracing services. This standard does not apply to the identification of jadeite origin from jadeite ores or jadeites that have undergone treatments such as washing, filling, dyeing, and heating. Main technical content: - UV-visible spectroscopy for the detection of Myanmar and non-Myanmar jadeite origins; - Infrared spectroscopy and laser Raman spectroscopy for the detection of Myanmar and Guatemalan jadeite origins; - X-ray fluorescence spectroscopy (XRF) for the detection of Myanmar and non-Myanmar green jadeite origins; - Electron probe microanalysis for the detection of Myanmar and non-Myanmar jadeite origins; - Presentation of jadeite origin detection results and requirements for detection technicians.
