SAR stands for Specific Absorption Rate*. Mobile telephones, WLANS and other transmission equipment emit radiation that comes into contact with the human body. To study the effects of the equipment on the human body, TÜV Rheinland EPS uses a unique (in the Netherlands) SAR robot, which registers radiation and passes on the readings to the researcher.

The Specific Absorption Rate (SAR) is a dosimetrically quantity defined as the limit within which the RF energy is absorbed per unit of mass. Worldwide regulations are operated to limit human exposure to RF energy. The test method and test systems are described in detail in OET bulletin 65, IEEE standard 1528 and the new IEC62209. The SAR measurement apparatus of TÜV Rheinland EPS meets all of these standards. The quantity of radiation is related to standards, which stipulate that the transmitters must not exceed a certain radiation level. This is called the 'exposure limit'. The requirements are laid down in the European R&TTE Directive (1999/05/EC) and in the Dutch Telecommunication Act. It is the responsibility of the manufacturer (or the party placing the product on the Dutch market) to ensure that these requirements are met.

Implemented under ISO 17025 accreditation
TÜV Rheinland EPS is the sole test laboratory accredited for SAR tests in the Netherlands and which can implement the tests according to international standards including GSM, DECT, WiFi, WiMAX, Bluetooth, PDA and many other products. The facility of TÜV Rheinland EPS is also available for development and scientific research purposes. The facility could help you, for instance, with the development of antennas for laptops, PCs and mobile telephones. Regulating and standardisation bodies (FCC, EU, ACA, ICNIRP) require or advise on the testing of low output Mobile Telecom Equipment (MTE) for conformity with the RF radiation safety standards. All handheld equipment or equipment worn on the body must be evaluated for human exposure standards. The standards set out basic requirements for the Specific Absorption Rate (SAR) or RF energy for each part of the body. In the USA, Europe, Australia and other countries the scope of SAR also includes equipment such as GSM, CDMA, DECT, PDA and some other remote (WLAN) devices
