EU ROHS2.0 standard
The EU Official Journal (OJ) issued the RoHS2.0 Amendment Directive (EU) 2015/863, and the EU RoHS2.0 update has finally settled, from the original six controlled substances: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr VI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), into ten controlled substances, new bis(2-ethylhexyl) phthalate (DEHP), butyl phthalate (BBP), DIBUTYL PHTHALATE (DBP) AND DIISOBUTYL PHTHALATE (DIBP) (PHTHALATE 4P) HAVE NOT BEEN OFFICIALLY INCLUDED IN THE LIST OF RESTRICTED SUBSTANCES (HBCCD), WHICH WAS PREVIOUSLY PRIORITIZED AS AN EVALUATION SUBSTANCE IN ROHS 2.0. The limits of the 10 controlled substances are 0.1% and 0.01% respectively.
After the issuance of the revised Directive, EU Member States will have until 31 December 2016 to transpose the Directive into national legislation and implement it. Since July 22, 2019, all electronic and electrical products (except medical and monitoring equipment) exported to Europe have to meet the requirements of this restriction, and from July 22, 2021, medical equipment (including in vitro medical equipment) and monitoring equipment (including industrial monitoring equipment) will also be included in the scope of this control. In addition, toy products that are already controlled by phthalates under Article 51 of Annex XVII of REACH will not be subject to the control of DEHP, BBP and DBP in this directive.
directives
On February 13, 2003, the European Parliament and the European Commission issued the Waste Electrical and Electronic Equipment Directive (hereinafter referred to as the "WEEE Directive") and the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (hereinafter referred to as the "RoHS Directive") in its "Bulletin", "RoHS Directive" and "WEEE Directive" stipulate that there are 102 kinds of products in ten categories that are included in the management of hazardous substances restriction and scrap recycling, and the first seven categories of products are China's main export electrical products. These include large household appliances, small household appliances, information and communication equipment, consumer products, lighting equipment, electrical and electronic tools, toys, leisure and sports equipment, medical equipment (except implanted or infected products), monitoring and control instruments, vending machines. On 3 December 2008, the European Union published a proposed amendment to the WEEE Directive (2002/96/EC) and the RoHS Directive (2002/95/EC). The aim of this proposal is to create a better regulatory environment, i.e., regulations that are simple, understandable, effective, and enforceable. The main contents of the revision of the RoHS Directive are:
1. Changed the wording of the law and clarified the scope and definition of the Directive;
2. Introduce the CE mark and EC declaration of conformity of the product;
3. Phased inclusion of medical devices, control and monitoring instruments in the scope of the RoHS Directive; There is no change to the six hazardous substances that are restricted, but four substances – diisobutyl phthalate (DIBP), phthalate (2-ethylhexyl ester) (DEHP), butyl benzyl phthalate (BBP) and dibutyl phthalate (DBP) – require priority assessment to see if they will be included in the scope of RoHS in the future: only for new products placed on the market from July 1, 2006. Including incandescent lamps and light sources for household use. There should be no violation of special directives or regulations on safety and health requirements – Vehicle ELV, Vehicle Directive; The Battery Directive, 91/157/EEC, 93/86/EEC&98/101/EC does not include: medical devices or monitoring equipment (WEEE Directive Categories 8, 9); repair parts placed on the market before July 1, 2006; Recycled products that were originally placed on the market before July 1, 2006.
Restricted toxic substances: · heavy metals: European new RoHS certificate (RoHS2.0) – Lead lead; –Mercury; –Cadmium; –Chromium (VI) hexavalent chromium.· Certain brominated flame retardants: Polybrominated biphenyls (PBB's); Polybrominated diphenyl ethers (PBDE's). Lead, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers: 0.1% (1000ppm).
Six categories of hazardous substances
RoHS targets all electrical and electronic products that may contain the above six hazardous substances in the production process and raw materials, mainly including: white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc., black goods, such as audio and video products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc.; Power tools, electric electronic toys, medical electrical equipment.
1. Lead (Pb) Examples of the use of the substance: solder, glass, PVC stabilizers
2. Mercury (Hg) (mercury) Examples of the substance used: thermostats, sensors, switches and relays, light bulbs
3. Cadmium (Cd) Examples of the use of the substance: switches, springs, connectors, housings and PCBs, contacts, batteries
4. Hexavalent chromium (Cr 6+) An example of the substance is used: metal anti-corrosion coatings
5. Polybrominated biphenyls (PBBS) Examples of the use of the substance: flame retardants, PCBs, connectors, plastic housings
6. Polybrominated diphenyl ethers (PBDE) Examples of the use of the substance: flame retardants, PCBs, connectors, plastic housings
Testing principles
According to the requirements of the EU WEEE&RoHS directive, qualified third-party testing agencies in China split the products according to the material and tested them for harmful substances in different materials. Generally speaking: metal materials need to test four harmful metal elements such as (Cd cadmium / Pb lead / Hg mercury / Cr6 + hexavalent chromium), plastic materials in addition to these four harmful heavy metal elements need to detect brominated flame retardants (polybrominated biphenyls PBB/polybrominated diphenyl ether PBDE), and different materials of packaging materials also need to be tested for heavy metals of packaging materials (94/62/EEC).
The following are the upper concentrations specified in RoHS for six hazardous substances: cadmium: less than 100ppm; Lead: less than 1000ppm; less than 3500ppm in steel alloys; Less than 4000ppm in aluminum alloy; Less than 40,000ppm in copper alloy; Mercury: less than 1000ppm; Hexavalent chromium: less than 1000ppm.
Reason for the rollout
Electrical and electronic equipment contains heavy metals harmful to human health, cadmium was found in the Netherlands in 2000 in the cables of a number of game consoles sold on the market. In fact, a large number of solder used in the production of electrical and electronic products, and the ink printed on packaging boxes contain harmful heavy metals such as lead.
Detection method
A. First, non-destructive screening with XRF is performed, which is fast, efficient, non-destructive, and low-cost. However, there are many interference factors and large errors.
B. After microwave digestion and acid digestion, the concentrations of Pb, Cd and Hg were determined by AAS or ICP-AES.
C. After Soxhlet extraction, the concentrations of polybrominated biphenyls and polybrominated diphenyl ethers were determined by GC-MS.
D. Determination of the concentration of Cr6+ in the colorless surface layer by spot test method or boiling water extraction method, or by EPA3060A test by ultraviolet-visible spectrophotometer.
The following table lists the specific restricted substances and limit values and testing instruments of ROHS1.0 and ROHS2.0 in detail.
