This procedure is shown schematically in Figure Z2.
The measurement is made after steady conditions have been reached but with active cooling in all compartments. Measurement methods for electromagnetic fields of household appliances and similar 6223 with regard to human exposure.
When heating highest temperature setting Charging a discharged battery having the highest capacity specified by the manufacturer Spread out and laid on a sheet of thermal 62233 Continuously, no load Continuously, no load Continuously As specified in 3. For undated references, the latest edition of the referenced document including 622233 amendments applies. NOTE Because of sharing power between induction heating units, the highest and continuous magnetic field is obtained when each heating units are operated separately.
Appliances that are constructed so that they only produce very weak magnetic fields, when the mains frequency is dominating, are considered to meet the requirements of this standard when all the following conditions are fulfilled: Suitable definitions and specified measurement techniques are applied in any exposure compliance measurement or assessment.

Preview Abstract Deals with electromagnetic fields up to GHz and defines methods for evaluating the electric field strength and magnetic flux density around household and similar electrical appliances, including the conditions during testing as well as measuring distances and positions.
General IECExposure to electric and magnetic fields in the low and intermediate frequency range — Methods for calculating the current density and internal electric field induced in the human body — Part Line spectrum evaluation No Result Fail Pass 5.
For details of these and other benefits contact Membership Administration. The smallest vessel recommended in the instructions for use is used. It ief the constant aim of BSI to improve the quality of our products and services. The cabinet is empty. This document is designed as one method for measurement and assessment of electromagnetic EM fields and their potential effect on the human body by reference to exposure standards.
This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. The bottom diameters of standard cooking vessels are: The outside diameter of the reference sensor shall not exceed 13 cm. Also in the cleaning mode, if available, as described in the instructions for use. For equipment for which it is not practical to test with each function operated separately, or where the separation of a particular function would result in the equipment being unable to fulfil its primary function, the equipment shall be operated with the minimum number of functions needed to operate.

If appliances, with their internal transformer or electronic circuit, are working at voltage lower than 1 V, they are deemed to comply without testing. A step by step procedure can be applied, from the easiest methods to the more complicated ones, see the flow diagram in Figure 1.
For this step it is important to know the distance lcoilwhich depends on the size of the measured household appliance. This will usually give a more realistic outcome than neglecting phase completely.
Efficient determination of current densities induced in the human body from measured lowfrequency inhomogeneous magnetic fields. It shall be verified, e. To compare the measured values with limits, the reference level B RL j must be used.
EN – Measurement methods for electromagnetic fields of household –
NOTE 2 The final value of the magnetic flux density is the vector addition of the values measured in each direction. If a switching action occurs during the measurements, the measurement has to be repeated.
The induction heating units are operated in turn, the other cooking zones not being covered. The magnetic flux density is measured at each relevant frequency. As you can see this coil is a good approximation. The evaluation of the factor k depends therefore on the sensor used. For ice arbitrary sensor area of Asensor the averaged magnetic flux density through it has to be calculated. You may find similar items within these categories by selecting from the choices below:.
If no recommendations are provided, the smallest standard vessel that covers the marked cooking zone is used. The value G is calculated from the following formula:
