ROHS, summary of requirements:

Toxic substances limit:
- heavy metals:
- Lead - Mercury
lead; mercury; cadmium
- Cadmium;
- Chromium (VI) six chromium.
, certain brominated flame retardant agent:
polybrominated biphenyls, polybrominated biphenyls (PBB 's);
polybrominated diphenyl ether - polybrominated diphenyl ethers (PBDEs' s).

, CD: 0.01% (100 ppm);
, lead, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers: 0.1% (1000 ppm). limits the maximum index

RoHS directive restricts the use of the following six types of harmful substances
1. Lead (Pb) using the material example: solder, glass, PVC
stabilizer 2. Mercury (Hg) (Shui Yin) using the material example: temperature controller, sensor, relay, switch and lamp
3. Cadmium (Cd) using the material example: switch, connector, spring, shell and PCB, 4.,
battery contact Six chromium (Cr 6+) using the example of material: metal corrosion coating of
5. Polybrominated biphenyls (PBB) using the material example: flame retardant, PCB, connector, plastic shell
6. Two polybrominated diphenyl ether (PBDE) using the material example: flame retardant, PCB, connector, plastic shell

test principle:
according to EU WEEE& ROHS directive requirements, CES is the products according to the material of the split, with different materials respectively for the detection of harmful substances. Generally speaking,
, metal material to test four kinds of harmful metals such as (CD / Pb Pb /Hg mercury /Cr6+ hexavalent chromium)
, plastic material, in addition to the inspection of the four kinds of harmful heavy metal elements also need to detect brominated flame retardant agent (polybrominated diphenyl PBB/ polybrominated diphenyl ether (PBDE)
, and packaging materials of different materials also need to separately test of heavy metals in packaging materials (94 / 62 / EEC)

Below
is RoHS in the six hazardous substances provisions limit concentration:
CD: less than 100ppm
lead: less than 1000ppm
steel alloy is in less than 3500ppm
aluminum alloy less less than mercury 40000ppm
4000ppm
copper alloy in the: less than 1000ppm
Cr (VI): the less than 1000ppm

introduced RoHS reasons
first noticed in electrical and electronic equipment containing heavy metals harmful to human health is 2000 in the Netherlands in a number of market sales of the game machine cable found that cadmium. In fact, electrical and electronic products in the production of a large number of use of solder, packaging, printing ink are containing lead and other harmful heavy metals.

when the implementation of the RoHS
will in July 1, 2006 implementation of the RoHS, when using or containing heavy metals, and polybrominated diphenyl ethers PBDE, polybrominated biphenyl PBB and other flame retardants in electrical and electronic products limit value is exceeded, will not be allowed to enter the EU market

ROHS certification application
the EU of 27 member countries: France, Germany, Italy, the Netherlands, Belgium, Luxembourg, Britain, Denmark, Ireland, Greece, Spain, Portugal, Austria, Finland, Sweden, Cyprus, Hungary, the Czech Republic, Estonia, Latvia, Lithuania, Malta, Poland, Slovakia, Slovenia, Bulgaria and Romania.

RoHS relates what products
RoHS for all the production process and raw materials may contain the six kinds of hazardous substances in electrical and electronic products, mainly including: daily appliances, such as refrigerators, washing machines, microwave ovens, air conditioning, vacuum cleaner, water heaters and other; black home appliance, such as audio, video products, DVD, CD, a television receiver, it products, digital products, communication products; electric tools, electric electronic toys medical electrical equipment

the progress of the RoHS
some big companies have attention to RoHS and began to take measures to deal with, such as Sony digital camera has been in on the box statement: This product uses lead-free soldering; lead-free printing ink.
Ministry of information industry in 2004 also introduced the electronic information products pollution control management measures "content is similar to the RoHS, and the" electronic information products pollution control standards working group was established in October, research and establishment conforms to our country electronic information products pollution control standard system; carry out and electronic information products, pollution prevention and control of standard research and revision, especially to speed up the development of industry is badly in need of materials, process, terminology, test methods and test methods of basic standard.
2011 in July 1st, the European Union in the Official Gazette (OJ) released a version of the RoHS instruction -- the instruction 2011/65/EU. A command
as Chinese electrical and electronic products manufacturing enterprises are very familiar with, the introduction of course it is striking one snag after another. Because of the differences between the parties in the process of revision is large, so this was intended to amendment in 2009 on the introduction of delays. In particular, whether to expand the scope of the product range and the scope of the material, including the European Commission, the European Parliament, the Council, the industry, NGO and so on have carried out the fierce debate.

2011/65/EU than the original RoHS instruction 2002/95/EU in different major
: 1. Expanding the product range: all electrical and electronic products are covered in the directive regulating range (including cable and spare parts), but given the Xintian into 8 types of medical equipment and class 9 monitoring and control instruments (including industrial monitoring instrument) a transition period. In addition, for these two types of products are given 20 exemptions are listed in Annex IV)
2. To clarify the definition of
3. Range of the controlled substances did not expand, still maintained the original six substances of the original limited requirements, but by the future review process, including DEHP material preferred to carry on the inspection, paving the way for instruction in the future to expand the scope of the controlled substances
4. Delete the producer (producer) regulations, and added "manufacturers" (manufacturer), "authorized representative" (authorised representative, "(importer) importer and distributor (distributor) is defined and the responsibilities were clearly defined
5. Related issues of the product to be affixed to the CE logo and CE logo.

this directive will be released on OJ twentieth date, member states need to before 2 January 2013 will be transformed into domestic law. The release of
2011/65/EU will give China's electronic and electrical products manufacturing enterprises bring certain influence, especially due to the medical device products, monitoring and control instruments products included in the regulatory scope of, so effect of these two kinds of manufacturing enterprises will be very great.
in addition, due to the electronic and electrical products need to stick attached to the CE mark, therefore, the industry with instruction, will also be a huge challenge.

common RoHS detection methods
1. anion: the British blue technology by ion chromatography
using oxygen bomb combustion, before the British blue technology processing, directly into the ion chromatography analysis
2. ion and its valence state:
by British blue cation chromatography, ion selective electrode method, atomic absorption method can detect
determine the cation valence states of elements by voltammetry polarography were analyzed

Rohs pronunciation. /rous/
detection method can be reference IEC62321:2008 electrical and electronic products in six kinds of restricted by determination of the concentration of a substance program
A. first by XRF are non-destructive screening, fast and efficient, non-destructive and low cost. But the interference factors, the error is large.
B., microwave digestion and acid digestion after using AAS or ICP-AES Pb Cd, Hg concentration determination.
C. Determination of the concentration of GC-MS in the determination of the concentration of more than the bromine, and the concentration of the more than the.
D. The concentration of EPA3060A in the surface layer of the Cr6+ was determined by point test or boiling water extraction method.

By EU legislation enacted a mandatory standard is ROHS certification
RoHS. Its full name is "restrictions on the use of instruction of certain hazardous substances in electrical and electronic equipment" (restriction of hazardous substances). The standard has been officially implemented in July 1, 2006, mainly for the specification of electronic and electrical products, materials and process standards, to make it more conducive to human health and environmental protection. The purpose of this standard is to eliminate lead, mercury, cadmium, six valence chromium, more than valence chromium, and a total of 6 substances, and the emphasis on the content of lead can not exceed 0.1%. Which involves the main source of lead in the following categories.

the EU RoHS and WEEE Directive the basic content of
directive of the European Parliament and the European Commission on February 13, 2003 in the "official gazette" released "waste electrical and electronic, Equipment Directive (hereinafter referred to as the WEEE Directive) and" electrical and electronic equipment restrictions on the use of certain Hazardous Substances Directive "(referred to as the" ROHS directive ")
" ROHS directive "and" WEEE Directive stipulates that the ten categories of 102 kinds of products included in the restriction of hazardous substances management and end-of-life recycling management, seven categories of products are the main export electrical products. Including large household appliances, small household appliances, information and communications equipment, consumer products, lighting equipment, electrical and electronic tools, toys, leisure and sports equipment, medical equipment (except for the infected products), monitoring and control equipment, automatic vending machines.
2008 in December 3rd, the EU issued a directive WEEE (2002/96/EC) and RoHS (2002/95/EC) of the revised proposal instructions. The purpose of this proposal is to create a better environment, that is, a simple, easy to understand, effective and enforceable regulations. The main contents are:
RoHS instruction revision 1. Change the legal term, clarify the scope and definition of
2. The introduction of CE logo products as well as EC declaration of conformity
3. Stages will be incorporated into medical equipment, control and monitoring equipment to the scope of the RoHS directive; without change of six kinds of hazardous substances
4., but four substances -- six HBCD (hbcdd), adjacent benzene dicarboxylic acid (2 - ethylhexyl) phthalate (DEHP), adjacent benzene dicarboxylic acid butyl benzyl phthalate (BBP) and dibutyl phthalate (DBP) -- Requirements for priority assessment, in order to study in the future are included in the category of restricted substances.

RoHS: new product
only for the July 1, 2006 market.
