The source current I Q can be chosen arbitrarily but should be equal for the calculation of J max and Bmax,sensor. Measurement methods for electromagnetic fields of household appliances and similar apparatus with regard to human exposure. Appliances are considered to meet the requirements of this standard when all the following oec are fulfilled: BSI also holds the copyright, in the UK, of the ied of the international standardization bodies. This standard includes specific elements to assess human exposure: Appliances that are constructed so that they only produce very weak magnetic fields, when the mains frequency ic dominating, are considered to meet the requirements of this standard when all the following conditions are fulfilled: Valid edition at date of issue.

Appliances include such equipment as household electrical appliances, electric tools and electric toys.

Preview Abstract Deals with electromagnetic fields up to GHz and defines methods ief 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.

The following sequence is used for the measurements: If no recommendations are provided, the smallest standard vessel that covers the marked cooking zone is used. Shorter sampling times may be used if the source is shown to be constant over a period greater than 1 s for 10 Hz — kHz signals.


The smallest vessel recommended in the instructions for use is used. NOTE 1 0 cm 0 cm 10 cm 10 cm 30 cm 30 cm 1,00 0,15 0,14 0,16 0,14 0,18 0, 0, 0, 0, 0, 0, The field source is situated directly under the housing inside of the appliance.

For this step it is important to know the distance lcoilwhich depends on the size of the measured household appliance. The load is 1 l of tap water, placed in the centre of the shelf. Kec An active notch filter is ifc suitable means for suppressing the mains frequency. This is the reference method, which has to be used in case of dispute. The following test report forms are related: Each function separately Controls at highest setting Continuously with the door closed.

Microwave and Optical Technology LettersMay 20,vol. The weighted result is obtained from the following formula: Looking in Table C.

The final weighted result, W, can be derived as follows: Step 4 Calculation of the coupling factor In case of measuring according to 5. Bioelectromagnetics, vol. Measurement of magnetic flux densities in the space around household appliances. Independent of the type of the signal, a time domain measurement of the value of the magnetic flux density 26233 be carried out. As specified in 3. For specific apparatus the corresponding coupling factor a c r 1 can be determined as described in Annex C, or if the value still exceeds the reference level when using the coupling factor, it does not necessarily follow that the basic restrictions will be exceeded.


Copyright Copyright subsists in all BSI publications. In addition to the listed restrictions, exposure of the head and torso to magnetic fields below 10 Hz shall be restricted to a peak value of mT for the general public, and mT in the controlled environment.

Erweiterte Momentenmethode zur Behandlung kompliziert aufgebauter und elektrisch grosser elektromagnetischer Streuprobleme. Appliances not intended for normal household use but which nevertheless may be approached by the public, lec may be used by laymen, are within the scope of this standard. This publication does not purport to include all the necessary provisions of a contract.

Various BSI electronic information services are also available which give details on all its products and services. Compliance with maximum permissible exposure or reference levels is sufficient for positive assessment of meeting these levels as specified in the appropriate exposure standard.

IEC – Standards Australia

This can be achieved by ief the time signal of the flux density and using a Fourier transformation for evaluating the spectral iiec. Line spectrum evaluation No Result Fail Pass 5. Result is the amount of the magnetic flux density for each detected frequency. Information regarding online access to British Standards via British Standards Online can be found at http: The simplest and more practical levels [limits] with which to comply are limits suitably timeaveraged in some cases on the electric E and magnetic B fields, measured in the absence of the human to be exposed to these fields.

This European Standard supersedes EN
