BS EN 62209-2:2018, also known as the European Standard for Human Exposure to Radio Frequency Fields from Handheld and Body-Mounted Wireless Communication Devices – Human Models, is a technical standard that outlines the procedures for measuring and assessing the specific absorption rate (SAR) in human models exposed to radio frequency fields emitted by handheld and body-mounted wireless communication devices.
Understanding SAR
The Specific Absorption Rate (SAR) is a measure of the rate at which energy is absorbed by the human body when exposed to radio frequency electromagnetic fields. It quantifies the amount of RF energy absorbed per unit mass of tissue and is typically expressed in watts per kilogram (W/kg). The SAR value indicates the potential for heating in body tissues due to RF exposure.
Importance of BS EN 62209-2:2018
BS EN 62209-2:2018 is crucial for ensuring the safety of individuals who use handheld and body-mounted wireless communication devices regularly. With the increasing prevalence of mobile phones, Bluetooth devices, and other wireless technologies, it is essential to evaluate their potential impact on human health. This standard provides guidelines for manufacturers to test their devices and ensure that they comply with SAR limits specified by regulatory authorities.
Testing Procedure and Compliance
The standard specifies detailed procedures for measuring SAR in various body parts when exposed to radio frequency fields. It considers different usage conditions, such as holding devices against the head, close to the body, or using them with accessories. Manufacturers need to perform these tests during the product development stage to assess compliance with SAR limits and ensure the safety of users. Regulatory bodies may require SAR test reports as part of product certification processes before devices are allowed to be marketed.
Compliance with BS EN 62209-2:2018 not only demonstrates the manufacturer's commitment to user safety but also ensures that wireless communication devices in the market do not pose unacceptable risks to human health. It allows consumers to make informed choices by providing information on SAR levels, helping them select devices with lower exposure potential if they have concerns about RF exposure.
In conclusion, BS EN 62209-2:2018 is a technical standard that plays a crucial role in evaluating the potential impact of handheld and body-mounted wireless communication devices on human health. By defining SAR measurement procedures and specifying compliance limits, it helps ensure user safety and promotes informed decision-making regarding RF exposure. Manufacturers should adhere to these guidelines to create products that meet regulatory requirements and minimize any potential risks associated with radio frequency fields.
