RoHS Certification

RoHS stands for Restriction of Hazardous Substances. As the name says, it is the standard given to the industry to restrict the usage of hazardous substances it applies in many industries. However, the Electronics industry and electrical products have the main impact.

What is RoHS Standard?

RoHS standard is a proven certification to ensure that the products have no usage of restricted hazardous substances. There are a couple of materials that are restricted under this rule. It is also known as Directive 2002/95/EC.

The standard was first introduced in the European Union. Now, it applies to many countries. The standard says that any hazardous material that might affect the environment, landfills, or any harmful material is not allowed. There is a proper process to test the products. Before that, let’s see the RoHS testing parameters.

RoHS testing parameters

As mentioned, RoHS has a list of substances that are not allowed. In some products, it is necessary to use these substances. Therefore, RoHS has specified a maximum quantity or level in which the substance can be used.

Upon the recent update on 22nd July of 2019, there were 4 more substances added under the new update of RoHS 3.

Here is the complete list of parameters and substances.

  • Cadmium (Cd): < 100 ppm
  • Lead (Pb): < 1000 ppm
  • Mercury (Hg): < 1000 ppm
  • Hexavalent Chromium: (Cr VI) < 1000 ppm
  • Polybrominated Biphenyls (PBB): < 1000 ppm
  • Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
  • Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
  • Benzyl butyl phthalate (BBP): < 1000 ppm
  • Dibutyl phthalate (DBP): < 1000 ppm
  • Diisobutyl phthalate (DIBP): < 1000 ppm


So, make sure the substance is present in the given quantity/level.

RoHS Testing Process

The next step is to get the certification. There is a testing process to get the RoHS certification.

Step 1: Testing

The first step is to test the material either on-site or one can also go with XRF testing or Lab path late solvent extraction testing. This is done to check the substances and the value of the restricted substances.

Step 2: Process Audit

This is a complete audit of the process of manufacturing. A document is created once the review is completed, which brings us to the next step.

Step 3: Documentation Review

There is a proper document created for all the things. It includes the bill of all the materials used. Also, along with this, it should have test reports, conformance, and compliance certificate forms, assembly drawings, material declaration, and should include a technical file with all the details.

The technical file should also include all the details about the product. There should be a product description and design structure details. When it comes to risk, the file should include risk assessments of all the materials and parts along with the conformity information. Lastly, it should have manufacturing and documentation records with harmonized standards and all the other procedures including specifications and conformity procedures.

Step 4: Certification

If everything stated above goes alright, the RoHS certification is issued.
