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.
You may experience issues viewing this site in Internet Explorer 9, 10 or The result is the weighted r. Equivalent source model for electrical appliances emitting low frequency magnetic fields. Energy controller settings shall be set to maximum. Compliance with maximum permissible exposure or reference levels is sufficient for positive assessment of meeting these levels as specified in the appropriate exposure standard.
The measurements are made up to 1 m above the cooking zone and 0,5 m below it. Information on standards BSI provides a wide range of ic on national, European and international standards through 622233 Library and its Technical Help to Exporters Service.
Line spectrum evaluation No Result Fail Pass 5. Generally applied methods are: Appliances include such equipment as household electrical appliances, electric tools and electric toys.
The measurement methods specified are valid from 10 Hz to kHz. An introduction to the conjugate gradient method without the agonizing pain.
Numerical calculation of lec densities induced in the human body caused by low frequency inhomogeneous magnetic sources. Worldwide Standards We can source any standard from anywhere in the world.
Appliances not intended for normal household use but which 62233 may be approached by the public, or may be used by laymen, are within the scope of this standard. The dependence on the frequency can be compensated by rescaling to the reference level instead of to the basic restriction see step 4. 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 Guidelines for limiting exposure to time-varying electric, magnetic and electromagnetic fields up to GHz.
Find Similar Items This product falls into the following categories. If it is not feasible to cover the frequency range in one measurement, 62323 weighted results of each measured irc range shall be added.
IEC – Standards Australia
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. The induction heating units are operated in turn, the other cooking zones not being covered. Various BSI electronic information services are also available which give details on all its products and 62233.
Abnormal operation of the appliances is not taken into consideration. This ensures that the measured value is independent of the direction of the magnetic field vector.
This document is not meant to supplant definitions and procedures specified in exposure 622333 but is aimed at supplementing the procedure already specified for compliance with exposure. It shall be verified, e. Measurement methods for electromagnetic fields of household appliances and similar apparatus with regard to human exposure.
NOTE 2 The radius r coil which is larger dimension than the distance r can not be determined by the procedure in Annex C.
Linear interpolation is used to obtain other values of r coil which shall 6233 exceed lcoil. Methodes de mesure des champs electromagnetiques emis iiec les appareils 62233 et appareils similaires en relation avec l’exposition humaine. When heating highest temperature setting Spread out and laid on a sheet of thermal insulation Spread out and laid on a sheet of thermal insulation As specified in 3.
The smallest vessel recommended in the instructions for use is used. The following test report forms are related: The field source has a distance between 10 cm and 40 cm from the surface of the housing inside the appliance.
Narda IEC-62233 Compatible Field Probe for the Extended Mobile Communications Range
This document is designed as one method for measurement ief assessment of electromagnetic EM fields and their potential effect on the human body by reference to exposure standards. Manufacturer’s specifications regarding short time operation have to be taken into account.
The thermostat is adjusted to lowest temperature setting. The field distribution from the hot spot with Bmax to 0,1 Bmax shall be continuous. As you can see this coil is a good approximation.
