ROHS certification

RoHS is a mandatory standard formulated by the EU legislation, its full name is the "Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment" (Restriction of Hazardous Substances). The standard has been officially implemented on July 1, 2006, mainly used to regulate the material and process standards of electrical and electronic products, so that it is more conducive to human health and environmental protection. The purpose of the standard is to eliminate lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products, a total of six substances, and focus on the content of lead can not exceed 0.1%.

RoHS scope:

Including incandescent lamps and light sources for household use.

Excludes: medical devices or monitoring equipment (WEEE Directive category 8, 9); repair parts placed on the market before July 1, 2006; reused products originally placed on the market before July 1, 2006.

-Heavy metals.

-Mercury.

-Chromium (VI) hexavalent chromium.

Polybrominated biphenyls (PBB's).

The maximum limit indicators are:

-Lead, Mercury, Hexavalent Chromium, PBBs, PBDEs: 0.1% (1000ppm).

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.

2. mercury (Hg) (mercury) Examples of the use of this substance: thermostats, sensors, switches and relays, light bulbs

4. hexavalent chromium (Cr 6+) Examples of the use of this substance: metal with corrosion coating

6. polybrominated diphenyl ethers (PBDE) Examples of the use of this substance: flame retardants, PCBs, connectors, plastic housings

Testing principles

-Metal materials need to test for four harmful metal elements such as (Cd / Pb lead / Hg mercury / Cr6+ hexavalent chromium)

-while packaging materials of different materials also need to be tested separately for packaging materials heavy metals (94/62/EEC)

Cadmium: less than 100ppm

Less than 3500ppm in steel alloy

Less than 40,000ppm in copper alloy

Hexavalent chromium: less than 1000ppm
