ROHS Directive Solution


RoHS is a mandatory standard established by EU legislation, its full name is "Restriction of Hazardous Substances Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment". The standard was officially implemented on July 1, 2006, and is mainly used to standardize the material and process standards of electrical and electronic products, making it more conducive to human health and environmental protection. The purpose of this standard is to eliminate 6 substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products, and it mainly stipulates that the content of lead should not exceed 0.1%. New directive 2011/65/EU (RoHS 2.0) to replace 2002/95/EC (RoHS) The new directive will come into force on July 21, 2011. Comparing RoHS2.0 with RoHS, the main changes are as follows:

1. Add appendices I and IA of the original WEEE directive as two appendices of RoHS.

2. From January 1, 2014 to January 1, 2017, medical equipment and monitoring equipment will be gradually included in the scope of RoHS control.

3. The manufacturer needs to formulate the EC declaration of conformity and affix the CE mark before the product is put on the market, and must keep the relevant technical documents and the EC declaration of conformity for at least ten years after the electronic and electrical products are put on the market.

4. If the substances listed in Appendix III (such as HBCDD, DEHP, BBP and DBP, etc.) cause unacceptable harm to human health or the environment due to their use, they will be evaluated in accordance with the provisions of Articles 69 to 72 of the REACH Regulations, and further This substance is included in the restricted substances in Appendix IV. The main test substances in the RoHS requirements are as follows:

"Testing Methods for Toxic and Hazardous Substances in Electronic Information Products" (hereinafter referred to as "Testing Methods", standard number SJ/T 11365-2006) limits the testing methods for harmful elements in RoHS requirements. Among them, X-ray fluorescence spectrometry (XRF), as the fastest and most convenient method, was formulated as a rapid screening 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).

For many years, EDXRF analyzers and XGT-WR series sold by HORIBA have provided customers with RoHS, ELV and halogen-free detection, and screened samples containing harmful elements such as Pb, Cd, Hg, Br, Cr, Cl, As, Sb, etc. measurement, which is now widely used around the world.

#1 Judgment time is related to the concentration of harmful elements and the material of the sample

#3 After the measurement is finished, it will automatically judge OK or NG
