LISUN solution for RoHS testing methods

Introduction to RoHS testing：
The European Union officially announced the 2002/95/EC Directive on 27^th January, 2003, the “Directive on the Prohibition of Certain Hazardous Substances in Electrical and Electronic Equipment” (referred to as the RoHS Directive), which took effect on 1^st July, 2006 . The directive requires that eight categories of electronic and electrical products sold in the EU market must undergo RoHS testing and must not contain six hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers.
ROSH Environmental Certification-Management Measures for the Control of Pollution by Electronic Information Products-The “Administrative Measures” implemented on 1^st March, 2007 require companies to affix their labels in accordance with the requirements of SJ/T 11364-2006.

Core content of “Administrative Measures”:
Producers should gradually reduce and eliminate the content of lead, mercury, cadmium, hexavalent chromium, polymeric brominated biphenyl (PBB), polymeric brominated biphenyl (PBDE) and other toxic and hazardous substances in products; for those that cannot be completely eliminated, The content of toxic and hazardous substances shall not exceed the relevant provisions of the standard.

The detection methods of 6 hazardous substances in RoHS:

“RoHs Testing Methods for Toxic and Harmful Substances in Electronic Information Products” (hereinafter referred to as “Testing Methods”, the standard number is SJ/T 11365-2006) limits the testing methods for harmful elements in the RoHS requirements. Among them, X-ray fluorescence spectroscopy (XRF) has been established as a quick screening method as the fastest and most convenient method. X-ray fluorescence spectroscopy (XRF) can be used to accurately test the corresponding standard samples of the five elements of lead (Pb), mercury (Hg), cadmium (Cd), chromium (Cr), and bromine (Br).

The EDX-2 RoHS test Instrument mentioned in the above detection method is a RoHS edxrf spectrometer developed by Lisun engineers according to market demand, which fully meets the requirements of the latest EU RoHS directive and is exported to foreign markets. The following is the product picture:
