Specific Absorption Rate – Accredited SAR Testing

About

EMC Technologies experts in SAR testing


RF transmitters used in close proximity to the human body must be evaluated against human Exposure standards which set basic restrictions for the Specific Absorption Rate (SAR) of RF energy by any part of the human body. This may include two-way radios, cellular phones, smartphones, spread spectrum, Bluetooth devices, wireless EFTPOS terminals and WLAN devices used in PDA/notebook/laptop/tablet computers. In Australia and Europe, virtually all devices exceeding the power threshold of 20mW (13dBm) and used in close proximity to the human body must comply with SAR requirements. There is no such blanket exemption in the USA and Canada where each product must be assessed against frequency/power level criteria.

SAR Requirements & Testing for Global Markets

EMC Technologies can provide SAR testing and certifying services for Europe (CE), Australia/New Zealand (RCM, USA (FCC) Canada (ISED), Japan, Singapore and most other countries.

  • In Australia SAR testing is mandatory for certain devices as part of RCM testing and compliance, as per Radiocommunications (Compliance Labelling—Electromagnetic Radiation) Notice 2014. Devices with RF power output >20mW and <20cm from the body/head require SAR testing.
  • In North America, the Federal Communications Commission (FCC) mandate Maximum Permissible Exposure (MPE) testing and compliance under FCC rules for intentional radiators. Depending on the RF power output and proximity to the human body SAR testing may be applicable. Requirements are determined on a case by case basis in accordance with FCC KDB procedures. There is no blanket exemption for low power devices.
  • The  Department  Innovation Science and Economic Development (ISED) formerly Industry Canada, specifies similar requirements to the FCC as per RSS-102.
  • In Europe EMR,  (known as EMF in Europe) compliance is required under the Radio Equipment Directive (RED).  Devices with RF power output >20mW and <20cm from the body/head require SAR testing.

We can provide measurement and validation for the most common frequencies between 20 MHz and 5.8 GHz. Continual investment in reference dipoles, flat phantoms and SAR measurement probes allow compliant head and body SAR measurements over most of the applicable frequency range including the less common bands:

30 MHz, 64 MHz, 150 MHz, 300 MHz, 600 MHz, 750 MHz, 900 MHz, 1300 MHz, 1450 MHz, 1640 MHz, 1800 MHz, 1950 MHz, 2100 MHz, 2450 MHz, 2600 MHz, 3000 MHz, 3300 MHz, 3500 MHz, 3700 MHz, 5.2 GHz 5.6 GHz and 5.8 GHz.

We have invested in fully optioned base station simulators such as R&S CMU200, CMW500 Anritsu MT8820A, MT8860B and Agilent model E6621A PXT which enables us to test virtually all mobile/cellular phones on the world market. Capability includes 2G/2.5G, 3G and 4G(LTE) – DECT, GSM, EGSM, E-GPRS, CDMA, WCDMA, EvDo, UMTS, HSDPA, HSUPA and LTE -A eMTC (LTE Cat-M1). Services extend to WLAN transmitters employed in Laptop PCs, Notebooks, Tablets and PDAs which utilise WLAN standards IEEE 802.11abgn or WiFi/WiMAX devices.

We have close links with world leaders in SAR research and measurement through a technical support agreement. Our clients have access to authoritative technical support in all aspects of SAR compliance.
