P1528.7 - Guide to Assess the Electromagnetic Fields (EMF) Exposure of Internet of Things (IoT) Technologies/Solutions
This Guide provides a methodology for classifying IoT devices based on RF exposure characteristics. Classification is based on frequency, bandwidth, radiated power, device shape, and typical installation configuration. Links between device class and available measurement/computational standards are provided. A framework criteria for exclusion classes for exposure assessment and criteria for addressing situations where exposure assessment is unavailable are included.
P62209-1528 - Recommended Practice for Measurement Procedures for the Assessment of Specific Absorption Rate (SAR) of Human Exposure to Radio Frequency Fields From Hand-Held and Body-Worn Wireless Communication Devices (Frequency Range of 4 MHz to 10 GHz)
This International Standard specifies protocols and test procedures for the reproducible and conservative measurement of the peak spatial-average SAR (psSAR) induced inside a simplified model of the head or the body by radio-frequency (RF) transmitting devices, with a defined measurement uncertainty. The protocols and procedures apply to a significant majority of the population including children during the use of hand-held and body-worn wireless communication devices. These devices may include single or multiple transmitters or antennas, and may be operated with their radiating structure(s) at distances up to 200 mm from a human head or body. This standard can be employed to evaluate SAR compliance of different types of wireless communication devices used next to the ear, in front of the face, mounted on the body, operating in conjunction with other RF-transmitting, non-transmitting devices or accessories (e.g. belt-clip), or embedded in garments. The applicable frequency range is from 4 MHz to 10 GHz. Devices operating in the applicable frequency range can be tested using the phantoms and other requirements defined in this standard. The device categories covered include but are not limited to mobile telephones, cordless microphones, and radio transmitters in personal, desktop and laptop computers for multi-band operations using single or multiple antenna, including push-to-talk devices. Wireless power transfer devices operating above 4 MHz may also apply this International Standard. This standard is not intended to apply to implanted medical devices.
1528a-2005 - IEEE Recommended Practice for Determining the Peak Spatial-Average Specific Absorption Rate (SAR) in the Human Head from Wireless Communications Devices: Measurement Techniques - Amendment 1: CAD File for Human Head Model (SAM Phantom)
Amendment to IEEE Std 1528-2003. This amendment to IEEE Std 1528 addresses certain text ambiguities in IEEE Std 1528-2003 and provides a CAD data file for the human head model from the original project but which was not included with the original standard.
