BS IEC 62233:2005
Any measured value below the maximum noise level is disregarded. A list of organizations represented on this committee can be obtained on request to its secretary.
Existing exposure standards, e. This is the reference method, which has to be used in case of dispute. The smallest vessel recommended in the instructions for use is used. The configuration and mode of operation during measurement shall be noted in the test report.
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. 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.
Magnetic Field Meter with 2 Sized Sensors | FT – Hioki
Measurement of magnetic flux densities in the space around household appliances. During the final measurement the sensor should remain stationary. If a switching action occurs during the measurements, the measurement has to be repeated. If no recommendations are provided, the smallest standard vessel that covers the marked cooking zone is used.
For appliances with highly localised fields the coupling factor a c r 1 given in Annex C can be taken into account. If using RF software codes, the application of a frequency scaling method  is possible: Internationally accepted SI-units are used throughout the standard.
See Scope Clause 1. The field distribution from the hot spot with B max to 0,1 B max shall be continuous. 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.
BSI also holds the copyright, in the UK, of the publications of the international standardization bodies. The bottom diameters of standard cooking ieec are: The following test report forms are related: Half-filled with water, without lid and highest heat setting Continuously without load Continuously without load, highest speed setting Continuously, highest settings Continuously, highest settings Continuously without load Continuously, highest heat setting Continuously, no load Without 62233, highest heat setting No-load, all settings e.
The measurements are made after stable operating conditions are reached. However, only circular current loops were used as sources to calculate the coupling factors. The factor k can now be determined e. It shall be verified, e. In the frequency range above kHz and below 10 Hz appliances in the scope iiec this standard are deemed to comply without testing unless otherwise specified in IEC series.
The outside diameter of the reference sensor shall not exceed 13 cm.
The weighted result is obtained from the following formula: Your basket is empty. The value G is calculated from the following formula: Click to learn more.
Worst case assumption, calculated by taking formula C. The source current Eic Q can be chosen arbitrarily but should be equal for the calculation of J max and Bmax,sensor.
This European Standard supersedes EN Appliances not intended for normal household use but which nevertheless may be approached by the public, or may be used by laymen, are within the scope of this standard.
Bioelectromagnetics, vol. Appliances may incorporate motors, heating elements or their combination, may contain electric 622333 electronic circuitry, and may be powered by the mains, by batteries, or by any other electrical power source.
You may find similar items within lec categories by selecting from the choices below:. The magnetic flux density is determined by using an averaging time of 1 s.
NOTE 1 It is permissible to use a single direction sensor not isotropic in combination with an appropriate summation method. For kec references, only the edition cited applies. NOTE An active notch filter is a suitable means for suppressing the mains frequency. NOTE 2 The radius r coil which is larger dimension than the distance r can not be determined by the procedure in Annex C.
The factor k therefore calculates to 14,?
Subscribing members of BSI are kept up to date with standards developments and receive ieec discounts on the purchase price of standards. The following sequence is used for the measurements: NOTE 1 The total measurement uncertainty can comprise aspects such as sensor position, operating conditions, noise background or the signal exceeding the dynamic range of the measuring instrument.

Also in the cleaning mode, if available, as described in the instructions for use. For calculation methods, IEC can be used. Appliances include such equipment as household electrical appliances, electric tools and electric toys.
