RoHS Certification

Posted on Jul 27, 2020 by Cullen Hikene

As companies increasingly strive to minimize their carbon footprint and generally reduce the presence of potentially hazardous substances in their materials, restriction of hazardous substances (RoHS) compliance has become increasingly relevant.

RoHS certification overview

Also known as lead-free, RoHS restricts the use of nine other substances in addition to lead in the manufacture of electronic and electrical equipment. RoHS compliance originated in the European Union in 2003 and restricted the use of hazardous materials and phthalates commonly found in electrical and electronic products. RoHS compliance affects all products sold into the EU after July 1, 2006.

Facilities, specific materials, and products that do not exceed specified thresholds for lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB), polybrominated diphenyl ether (PBDE), bis(20thylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), and diisobutyl phthalate (DIBP) can earn RoHS certification.

To achieve RoHS certification, products must not exceed these thresholds:

  • Lead—less than 1000 parts per million
  • Mercury—less than 100 parts per million
  • Cadmium—less than 100 parts per million
  • Hexavalent chromium—less than 1000 parts per million
  • Polybrominated biphenyls—less than 1000 parts per million
  • Polybrominated diphenyl ethers—less than 1000 parts per million

The following categories require RoHS compliance:

  • Large household appliances: refrigerators, washers, stoves, air conditioners
  • Small household appliances: vacuum cleaners, hairdryers, coffee makers, irons
  • Computing and communications equipment: computers, printers, copiers, phones
  • Consumer electronics: TVs, DVD players, stereos, video cameras
  • Lighting: lamps, lighting fixtures, light bulbs
  • Power tools: drills, saws, nail guns, sprayers, lathes, trimmers, blowers
  • Toys and sports equipment: videogames, electric trains, treadmills
  • Automatic dispensers: vending machines, ATMs

Gaining RoHS certification

If your part is RoHS compliant, these steps are required to gain certification:

  1. Documentation review. Review bill of materials, assembly drawings, and material declarations for each component and products, test reports, and conformance certificates.
  2.  Audit. Inspect all manufacturing processes needed to meet RoHS compliance.
  3. Test. Perform on-site portable XRF testing to determine the level of each restricted substance.
  4. Certification. RoHS certification is issued following a successful audit.

On-site testing

An X-ray Fluorescence spectroscopy (XRF) is used to perform RoHS compliance testing. Testing typically focuses on the parts of a product where the restricted substances are most likely to be found.

XRF analyzers are available for rent or purchase as stand-alone, bench-top, and handheld models. Other methods are available for analyzing parts such as Fourier Transform Infra-red Spectroscopy (FTIR) testing and, in some cases, Scanning Electron Microscope (SEM) testing.

Update your Shopsight profile

If your facility is RoHS-compliant, it is essential to add this certification to your Shopsight profile. Click here to log in and update your information.

If you have any of the important certifications, please include them on your profile at the Facility level: ISO 9001, AS9100, ISO 13485, RoHS Compliant, ITAR Certified, and any others you may have.
