In the frequency range above kHz and below 10 Hz appliances in the scope of this standard are deemed to comply without testing unless otherwise specified in IEC series. The magnetic flux density is determined by using an averaging time of 1 s. Existing exposure standards, e. Do you need a multi-user copy? Contact the Information Centre. In the frequency range above kHz and below 10 Hz appliances in the scope of this standard are deemed to comply without testing unless otherwise specified in IEC series.

In case of measuring according to 5. It is incorporated by Royal Charter. Measurement of magnetic flux densities in the space around household appliances.

TC – Methods for the assessment of electric, magnetic and electromagnetic fields associated with human exposure rss. Looking in Table C.

BS IEC 62233:2005

For fields with several frequency components, the dependency on frequency of the reference levels is taken into account by implementing a transfer function A which is inverse of the reference level expressed as a function of the frequency. The source current I Iwc can be chosen arbitrarily but should be equal for the calculation of Eic max and Bmax,sensor. The measurement is not made at the rear of the appliance line D if it is intended to be used when placed against a wall.


Appliances are considered to meet the requirements of this standard when all the following conditions are fulfilled: 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 It supersedes BS EN The procedure is applicable to concentrated sources only.

If the conditions are not fulfilled another measurement according to the reference method is recommended.

EN – Measurement methods for electromagnetic fields of household –

This calculation yields the electric field strength E’ at the frequency f ‘. Learn more about the cookies we use and how to change your settings. The cabinet is empty. Information regarding online access to British Standards via British Standards Online can be found at http: Your basket is empty.

The configuration and lec of operation during measurement shall be noted in the test report.

The weighted result is obtained from the following formula: The start and finish of each common modification is indicated in the text by tags??. For dated references, only the edition cited applies. You may find similar items within these categories by selecting from the choices below:. The maximum Bmax, sensor has to be taken.



662233 For this step it is important to know the distance lcoilwhich depends on the size of the measured household appliance.

The following test report forms are related: The field distribution from the hot spot with B max to 0,1 B max shall be continuous. NOTE 1 The total measurement uncertainty can comprise aspects such 662233 sensor position, operating conditions, noise background or the signal exceeding the dynamic range of the measuring instrument.

Manufacturer’s specifications regarding short time operation have to be taken into account. For calculation methods, IEC can be used. The factor k can now be determined e. With appliances with highly localized fields, this has to be performed after taking the coupling factor ac r1 given in Annex C into account.

This ensures that the measured value is independent of the direction of the magnetic field vector. This standard includes specific elements to assess human exposure:
