Brief introduction of rohs2.0 test

Rohs2.0: RoHS VI + hbcdd + 3P (DEHP, DBP, BBP)

On January 27, 2003, the European Parliament and the Council adopted Directive 2002 / 95 / EC, namely "the directive on the restriction of the use of certain hazardous substances in electronic and electrical equipment", or ROHS directive for short. After the issuance of RoHS directive, it has become a formal law within the scope of EU since February 13, 2003; before August 13, 2004, EU member states have been transformed into their own laws and regulations; on February 13, 2005, the European Commission reviewed the scope of the directive, considered the factors of new technology development, and formulated the added items of banned substances list; after July 1, 2006, the EU market will be officially It is forbidden to sell the products with six kinds of substances exceeding the standard.

Since July 1, 2006, six harmful substances, such as lead, mercury, cadmium, hexavalent chromium, PBB and PBDE, have been restricted in new electronic and electrical equipment products put on the market.

Four harmful metal elements (CD, CD, Pb, Pb, Hg, Hg, Cr6 + hexavalent chromium) shall be tested for metal materials

In addition to these four harmful heavy metal elements, brominated flame retardants (PBB / PBDE) should also be tested for plastic materials

At the same time, it is also necessary to test the heavy metals of different packaging materials (94 / 62 / EEC)

The following are the upper limit concentrations specified for six hazardous substances in RoHS:

Cadmium: less than 100ppm

Lead: less than 1000ppm (less than 2500ppm in steel alloy, less than 4000ppm in aluminum alloy, less than 4000ppm in copper alloy)

Mercury: less than 1000ppm

Hexavalent chromium: less than 1000ppm

PBB: less than 1000ppm

PBD: less than 1000ppm



On July 1, 2011, the European Parliament and Council issued directive 2011 / 65 / EU (RoHS 2.0) in the official journal of the European union to replace the new Directive 2002 / 95 / EC, which will enter into force 20 days later (i.e. July 21, 2011).

Although no new restricted substances were added, four toxic and harmful substances (hbcdd, DEHP, DBP and BBP) were selected as candidates for restricted substances.
