GB/T 43275-2023 《Screening determination of certain elements of antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium in plastic for toys—Energy dispersive X-ray fluorescence spectrometry》 Related products

The document warns of the potential dangers when using X-ray fluorescence spectrometry (XRF) to screen and analyze antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium and other eight elements in toy plastics. First, it is emphasized that X-Rays are harmful to the human body. XRF users must receive training in the operation of Light spectrum meters, have relevant operation techniques and sampling knowledge, and operate with caution, follow the manufacturer's safe use instructions and national and occupational safety regulations. Second, personnel using this document should have formal laboratory work practice experience, and it is clear that this document does not cover all possible safety issues. XRF users are responsible for taking appropriate safety and health measures and ensuring compliance with relevant national regulations. The paper describes the methods and procedures for screening and analysis of antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium in toy plastics by using energy dispersion X-ray fluorescence spectrometry. It is applicable to the screening of antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium transferable elements in toy plastics, as well as the screening of total elements. Relevant standards are cited in the document, including basic specifications for toy safety (GB 6675.1) and migration of specific elements (GB 6675.4), and terms and definitions are provided, such as screening and X-ray fluorescence spectrometry.
