Absorption Ratio Test (SAR)
Introduction to SAR testing
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/kg.

Introduction to lcs SAR laboratory capabilities

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, WIFI and other communication standards.
Introduction to SAR laboratory equipment
SAR

The latest introduction of the internationally advanced SATIMO SAR test system, this test system meets domestic and foreign standards such as YD/T 1644, EN62209-1, FCCOET Bulletin 65, etc. The SAR test system supports the double head table option and has the characteristics of fast test speed and high equipment stability.

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.
SAR test standards
SAR testing standards of various countries
Advantages of lcs SAR testing
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).
