ROHS certification new directive

Product Details

How to confirm whether the product contains substances that are harmful to the environment and difficult to handle? If the product passesROHS environmental certification, Then this can be considered yes. RoHS applies to the "reduction of certain hazardous substances" for electrical and electronic equipment, and this restriction is based on the European Union Directive 2011/65/EU.

The full Chinese name of ROHS is "Instructions on Restricting the Use of Certain Hazardous Ingredients in Electrical and Electronic Equipment". Simply put, it is a mandatory standard established by EU legislation. This standard is effective from July 1, 2006. start to implement.

The main purpose of this logo is to standardize the materials and process standards of electronic and electrical products, making it more conducive to human health and environmental protection, and eliminating six substances in electrical and electronic products, including lead, mercury, cadmium, hexavalent chromium, and polybrominated biphenyls And polybrominated diphenyl ethers, it is specifically stipulated that the lead content should not exceed 0.1%.

EU requires 6 items to be tested, and this directive takes effect as a ROHS directive.

Restricting certain hazardous substances commonly used in electronics and electronic equipment is the subject of the ROHS directive. All components that meet the ROHS requirements need to be tested for the 6 substances mentioned above. For cadmium and hexavalent chromium, it must be less than 0.01% (weight) of the same material level. The definition and objectives of the RoHS directive are very simple.

For lead, polybrominated biphenyls and polybrominated diphenyl ethers, based on the weight of the raw homogeneous material, the material shall not exceed 0.1%. Any RoHS-compliant component must contain 100 ppm or less mercury, and mercury must not be intentionally added to the component. , Certain military and medical equipment are not subject to the RoHS standard.

Therefore, products within the scope of the RoHS test must be processed. What is the ROHS test method and what is the specific processing procedure?

ROHS certification method:

1. ROHS integration: The engineer should view the ROHS report of all parts of the product provided by the customer, integrate it into the report and publish it internally.

2. ROHS chemical test: Our engineers first decompose the sample by physical splitting method to obtain the material to be tested.

There are four ROHS tests for metal materials; six ROHS tests for plastics. Note: Each part of the product can be divided into four and six tests, because these parts may contain metal and plastic materials.

3. XRF scanning chemical test: The engineer first decomposes the sample by physical splitting method to obtain the material to be tested, and then performs XRF scanning. After obtaining the scan results, chemical test analysis is performed on the test results of some materials to be tested, and the results are analyzed.
