RoHS Certification

Home / Services / RoHS Certification

RoHS (Restriction of Use of Hazardous Substances) regulations limit or ban specific substances — lead, cadmium, polybrominated biphenyl (PBB), mercury, hexavalent chromium, and polybrominated diphenyl ether (PBDE) flame retardants – in new electronic and electric equipment.

RoHS compliance means acting in full accordance with RoHS regulations and documenting your testing for RoHS controlled substances.

RoHS training involves teaching yourself and your employees about RoHS regulations and correct testing for RoHS controlled substances. Ignorance is not considered a viable excuse for RoHS non-compliance, so it is important to learn about RoHS and to ensure that your company is fully RoHS compliant. Learn the RoHS compliant definition and seek out consultants or additional assistance if you are unsure of the RoHS compliance definition for your business or are uncertain about testing procedures.

The Reduction of Hazardous Substances (RoHS) regulations set limits for the following substances:

To certify to the above compliances, these substances must not be intentionally added to the product AND cannot exceed the following maximum allowable levels as a trace substance: 0.1% (1,000 ppm) for: Lead*, Mercury, Hexavalent Chromium, PBB and PBDE 0.01% (100 ppm) for: Cadmium

Lead as an alloying element in copper alloys is allowed up to 4.0% (40,000 ppm); in steel up to 0.35% (3,500 ppm) is allowed; in aluminum alloys up to 0.40% (4,000 ppm) is allowed.

Compliance Assurance System

Restricted Substance Controls (RSC) defines the actions and mechanisms you can take to prevent restricted substances from inclusion in your products. To ensure RSC are effective, the procedures should be integrated into an overall Compliance Assurance System (CAS).

EU Enforcement authorities and OEM customers are requesting documentation of producer’s RoHS compliance procedures to demonstrate that appropriate systems are in place to ensure on-going compliance.

RoHS Certifiation helps you in developing your “Compliance Assurance System“.

Examples of product components containing restricted substan

RoHS restricted substances have been used in a broad array of consumer electronics products. Examples of leaded components include:

Cadmium is found in many of the above components, examples include plastic pigmentation, nickel-cadmium (NiCd) batteries and CdS photocells (used in night lights). Mercury is used in lighting applications and automotive switches, examples include fluorescent lamps (used in laptops for backlighting) and mercury tilt switches (these are rarely used nowadays). Hexavalent chromium is used for metal finishes to prevent corrosion. Polybrominated biphenyls and diphenyl Ethers/Oxides are used primarily as flame retardants.
