LISUN EDX-2 RoHS Testing Equipment – After Sales Questions and Answers

1. RoHS Compliance Testing:
• RoHS testing of electronic appliances
• Alloy manufacturing RoHS test
• RoHS testing of coating and plating
• RoHS testing of plastics and plastic parts
• Various hazardous element testing area

2. Product Instruction | What RoHS means?
RoHS is a mandatory standard established by EU legislation. Its full name is “Restriction of Hazardous Substances” (Restriction of Hazardous Substances). This standard has been formally implemented since July 1, 2006 which is mainly used to regulate the materials and process standards of electrical and electronic products. And making it more conducive to human health and environmental protection. The purpose of this standard is to eliminate six items of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers in electrical and electronic products, and stipulate that the content of lead should not exceed 0.1%. The new directive 2011/65/EU (RoHS 2.0) to replace the 2002/95/EC (RoHS) new directive will take effect on July 21, 2011. Comparing RoHS2.0 and RoHS, the main changes are as follows:
• Add Appendix I and IA of the original WEEE Directive as two appendices of RoHS.
• From 1^st,January, 2014 to 1^st, January, 2017, medical equipment and monitoring equipment will be gradually included in the scope of RoHS control.
• Manufacturers need to make an EC declaration of conformity and affix the CE mark before the product goes on sale. After the sub-electrical products on sale in market, relevant technical documents and EC declarations of conformity must be retained for at least ten years.
• If the substances listed in Appendix III (such as HBCDD, DEHP, BBP, DBP, etc.) cause the human health and the environmental unacceptable harzards, it will be evaluated in accordance with the provisions of Articles 69 to 72 of the REACH Regulation, and this substance will be further included in the restricted substances in Appendix IV.

Q1: Problems on the testing of Cr and br
A1: In nature, there are three states of Cr: 0 valent chromium, 3 valent chromium and 6 valent chromium. The European Union controls 6 valent chromium. TBD indicates that further analysis is needed, because we test the total chromium content, which exceeds 1000ppm. However, it is uncertain whether it is 6 valent chromium controlled by the European Union. The alloy contains 0 valent chromium and 6 valent chromium, which are most common in the passivation residue of potassium dichromate solution on the surface of color zinc coating.

Br is also the total amount of BR bromine tested. If the total amount exceeds the standard, it means there is a risk of exceeding the standard. It cannot mean that the PBBs and PBDEs controlled by the EU exceed the standard. It needs to be sent to a third-party testing agency for further analysis and determination, or purchased a chromatograph for self inspection.
