ROHS testing is a process of detecting harmful substances in electronic products. These harmful substances include chemical substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. The ROHS Directive is a regulation aimed at limiting the use of harmful substances in electronic products to protect human health and the environment. The following will provide a detailed introduction to the detection objects and objectives of ROHS testing.

1. Test object

The detection object of ROHS testing is harmful substances in electronic products. These substances mainly come from the components of electronic products, such as circuit boards, wires, cables, batteries, etc. These components may contain harmful substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers, which can have negative effects on human health and the environment.

The detection objects of ROHS testing include the following substances:

-Lead: Lead is one of the most common harmful substances in electronic products. It can affect the human nervous system, brain, and kidney function, and may also cause pollution to the environment.

-Mercury: Mercury is a toxic substance that can affect the nervous system and kidney function in humans. It may also cause pollution to the environment.

-Cadmium: Cadmium is a toxic substance that can affect the human kidney and skeletal system. It may also cause pollution to the environment.

-Hexavalent chromium: Hexavalent chromium is a toxic substance that can affect human skin and respiratory system. It may also cause pollution to the environment.

-Polybrominated biphenyls and polybrominated diphenyl ethers: These substances are ozone depleting substances that may have negative impacts on human health and the environment.

2. Purpose

The main purpose of ROHS testing is to ensure that the content of harmful substances in electronic products meets the requirements of the EU ROHS Directive. The ROHS directive stipulates that the content of these substances in electronic products must meet certain standards. These standards include:

-Lead: The content of lead in electronic products cannot exceed 0.1%.

-Mercury: The content of mercury in electronic products cannot exceed 0.1%.

-Cadmium: The content of cadmium in electronic products cannot exceed 0.01%.

-Hexavalent chromium: The content of hexavalent chromium in electronic products cannot exceed 0.1%.

-Polybrominated biphenyls and polybrominated diphenyl ethers: The content of these substances in electronic products must be less than 1000 ppm.

Through ROHS testing, the quality and safety of electronic products can be ensured, while protecting human health and the environment. In addition, ROHS testing can also help enterprises meet the requirements of the international market. Many countries and regions have similar regulations and standards that require the content of harmful substances in electronic products to meet certain standards. By conducting ROHS testing, companies can demonstrate that their products meet these standards and meet the requirements of the international market.
