Specific Absorption Rate testing CE-RED、FCCID、IC、Thailand、India、KC、NCC、MIC certification

Certification Introduction:

The full name of SAR in English is Specific Absorption Rate, and in Chinese it is generally called electromagnetic wave absorption ratio or specific absorption rate. It is the electromagnetic wave energy absorption ratio of mobile phones or wireless products. It is defined as: under the action of external electromagnetic fields, the induced electromagnetic field will be generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate current, resulting in the absorption and dissipation of electromagnetic energy. SAR is commonly used in biological dosimetry to characterize this physical process. The meaning of SAR is the electromagnetic power absorbed or consumed by unit mass of human tissue, in W/k

The LCS SAR laboratory supports SAR testing of mobile devices such as mobile phones, data cards, tablets, and walkie-talkies. The test frequency range is 300MHz-6GHz, including 2G, 3G, 4G, 5G, WIFI and other communication standards.

Summarize:

SAR testing is mainly aimed at products containing wireless emissions whose antennas are within 20cm of the human body, and the power of the product exceeds the power value exempted by various countries.

Due to the widespread popularity of radio equipment (such as mobile phones) around the world, more and more government departments, telecommunications regulatory agencies, etc. require that electromagnetic wave radiation be reduced to an appropriate level.
In order to meet the urgent needs of the majority of mobile phone manufacturers, LCS Testing has introduced an advanced mobile phone electromagnetic wave energy absorption ratio (SAR) testing system. This test system fully complies with the SAR standard requirements of IEEE/IEC/EN and American ANSI. It is fast, accurate, safe and efficient. It is also the most widely used and widely recognized SAR test system in laboratories. The test frequency range of this system reaches 6GHz, and it can conduct certification tests for GSM, CDMA, WLAN and other types of products (not limited to mobile phones).
