EUROLAB laboratory provides testing and compliance services within the scope of EN 62479 standard. The EN 62479 standard provides simple conformity assessment methods for low-power electronic and electrical equipment up to an exposure limit for electromagnetic fields (EMF).

If such equipment cannot be demonstrated to comply with applicable EMF exposure requirements using the methods contained in this standard for EMF assessment, other standards may be used for conformity assessment, including IEC 62311 or other (EMF) product standards.
Usable antenna power is defined as the maximum power supplied to the antenna feedline that can theoretically be transmitted to a directly connected load by a source with positive true part impedance when the impedance of the load is very diverse, averaged over a time interval equal to the averaging time.
Usable antenna power is obtained when the resistance of the load is equal to that of the source and its reactance is equal in magnitude but of opposite sign. However, other scenarios are possible, for example, if the PA is monitoring current rather than actual power, a varying antenna impedance (when the DUT is operated close to the body) may actually result in a higher output power than the matched load. Next, a push-pull analysis should be performed with various realistic loads (based on antenna impedance around the body).
In some cases, conditions such as overheating or overvoltage prevent the available antenna power from being obtained. Time will be averaged during continuous or maximum duty cycle transmission at maximum power whenever possible for a given technology.
EN 62479 provides simple conformity assessment methods for low power electronic and electrical equipment up to an exposure limit for electromagnetic fields (EMF).
