Human exposure to electromagnetic fields
The assessment of human exposure is mandatory for all electrical and electronic equipment. Sicom Testing applies different valuation techniques required by the standards and can perform in its own laboratories testing of SAR. In the case of non-compliance, Sicom Testing works with clients to find the best solutions for placing the product on the market regularly.
Sicom Testing performs the tests of human exposure and the extent of SAR (Specific Absorption Rate) according to all European standards on electrical devices, electronic and radio products.
The verification of human exposure to electromagnetic fields are part of the safety tests and are particularly important because they are related to the protection of the health of people and pets.
The attention to these aspects of safety has increased in recent years and today the tests are mandatory for all electrical and electronic equipment, especially for those present in the home and workplace, including lighting equipment.
The sensitivity to this topic has been stimulated by the intensive use of mobile phones and the presence of strong radio and television transmitters. It was realized that the EMF sources are many and, lately, it has become common knowledge that radio transmitters are not the only ones to emit potentially harmful fields to people.
The verification of compliance with the limits of human exposure is conducted today by applying different methods depending on the characteristics of the electromagnetic field source and its position with respect to persons. To be done properly, it requires skilled and experienced personnel in this field.
So there are specific assessment methods for equipment used near the ear, such as mobile phones, those used near the body including laptops, and those that are located on a table or on a wall or on the floor such as routers Wi-Fi and appliances.
In order to be marketed, all portable devices being used in the vicinity of the head or body must be subjected to the measurement of SAR to demonstrate their compliance with these standards. The SAR is defined as the amount of EM energy absorbed by the human body per unit mass and is measured in W / Kg.
The telecommunications market has increased the production of devices used in close proximity to the human body and regulations they have been adopted all over the world that limit the maximum exposure levels.
- The Council Recommendation 1999/519/EC defines the "Limitation of exposure of the population to electromagnetic fields 0 Hz a 300 GHz”,
- The Directive 2013/35/EU outlines the "minimum of safety and health requirements regarding the exposure of workers to the risks arising from physical agents (electromagnetic fields)”.
