RoHS directive originated from the European Union, with the rise of the production and use of electrical and electronic products (also known as EEE). During the use, treatment and disposal of environmental electrical equipment, harmful substances (such as lead and cadmium) may be released, resulting in serious environmental and health problems. RoHS helps prevent such problems. It limits the existence of specific harmful substances in electrical products, and safer substitutes can replace these substances. The following is a brief analysis of ROHS detection for your reference.

The limit requirements for RoHS2.0 ten hazardous substances are as follows:

S/N Substance name Limit value conversion percentage 1 Cadmium (Cd)<100 ppm0.01% 2 Lead (Pb)<1000 ppm0.1% 3 Mercury (Hg)<1000 ppm0.1% 4 Hexavalent chromium: (Cr VI)<1000 ppm0.1% 5 Polybrominated biphenyls (PBB)<1000 ppm0.1% 6 Polybrominated diphenyl ethers (PBDE)<1000 ppm0.1% 7 Di (2-ethylhexyl) phthalate (DEHP)<1000 ppm0.1% 8 Benzyl phthalate (BBP)<1000 ppm0.1% 9 Dibutyl phthalate (DBP) <1000 ppm 0.1% 10 DIBP<1000 ppm 0.1%

The ppm in the above limit requirements is the concentration unit expressed in parts per million of the solute mass in the total solution mass, also known as the concentration in parts per million. 100 ppm=0.01%。 1000 ppm=0.1%。

In addition, it should be noted that the RoHS2.0 directive has been included in the scope of CE certification. Therefore, RoHS2.0 needs to be assessed according to the CE conformity assessment procedure, issued with a CE RoHS certificate or self declaration, and affixed with a CE certification mark on the product itself or on the outer package.

The RoHS testing and certification process is as follows:

1. The entrusting party provides the product information, whether the product is finished product or part, whether the material is metal or non-metal, and the BOM of the product bill of materials;

2. RoHS certification methods include RoHS integration, RoHS scanning+chemical testing, and RoHS chemical testing. The certification methods are determined according to product conditions and customer requirements;

3. Evaluate and quote according to product materials and certification methods;

4. The entrusting party confirms the quotation, fills in the application form, provides samples and materials, and opens the case after arranging the payment;

5. If the certification method is RoHS integration (generally for finished products), sort out the data, and issue the integration report and certificate;

6. If the certification method is scanning+chemical testing (generally for finished products) or RoHS chemical testing (generally for parts), arrange product testing;

7. If the test is unqualified, arrange the materials exceeding the standard to be re sampled for testing until they are qualified;

8. After passing the test, issue RoHS test report and certificate;

9. Send the certificate report and close the case.

Important influence of RoHS detection:

Since 2006, all electrical products sold in the EU market must pass the RoHS compliance test. The RoHS directive covers all products from kitchen appliances (such as toasters and refrigerators) to mobile phones, laptops and lighting equipment. It does not distinguish between EEE for consumer use and EEE for professional and industrial purposes.

Therefore, if you manufacture, import or distribute the goods covered by the Directive, the content of harmful substances in the products shall not exceed the allowable level. As an economic side, you need to identify the harmful substances in the products and find suitable substitutes when possible. If the latter cannot be achieved, the exemption of the rule must be checked. In addition, you need to ensure that your supplier CE certifies the components they provide.
