The measurements are made while the appliance is energized. You may find similar items within these categories by selecting from the choices below:.

Users of British Standards should make sure that they possess the latest amendments or editions.
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. This will usually give a more realistic outcome than neglecting phase completely. The basic restriction for the current density is J BRthe basic restriction for the internal electric field strength is E BR ——————— 2 To be published. The measurement is made after steady conditions have been reached but with active cooling in all compartments.
They take the dimension of the part of body which is in the field into account as well. The field source has a distance between 10 cm and 40 cm from the surface of the housing inside the appliance. Any measured value below the maximum noise level is disregarded. Measurement of magnetic flux densities in the space around household appliances.
The factor k can now be determined e. The maximum Bmax, sensor has to be taken. The measurements are made after stable operating conditions are reached. Generally applied methods are: Ice is incorporated by Royal Charter.

This method provides a value for the coupling factor depending on the radius of the equivalent coil. The following dates are applicable: Guidance to assess uncertainty is provided in IEC Copyright Copyright subsists in all BSI publications. The result is the weighted r. 662233 and continue Learn more about the cookies we use and how to change your settings.
MAGNETIC FIELD HiTESTER
It is recommended to use a small sensor, e. A step by step procedure can be applied, from the easiest methods to the more complicated ones, see the flow diagram in Figure 1. The thermostat is adjusted to lowest temperature setting. This procedure is shown schematically in Figure Z2. For fields with several frequency proportions the calculation of a frequency weighted sum is necessary.
However, pre-set controls are used in the intended position. Numerical study on an equivalent source model for inhomogeneous magnetic field dosimetry in the low-frequency range. The curve with circles in above Figure D.
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. 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 load, highest heat setting No-load, all settings e.
The measurement methods specified are valid from 10 Hz to kHz. NOTE 2 The procedure is applicable only for concentrated sources.

Users are responsible for its correct application. 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 insulation Continuously, no load Continuously, no load Continuously As specified in 3.
NOTE This applies e.
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 622233 coupling factor, it does not necessarily follow that the basic restrictions will be exceeded.
Appliances not intended for jec household use but which nevertheless may be approached by the public, or may be used by laymen, are within the scope of this standard.
The source current I Q can be chosen arbitrarily but should be equal for the calculation of J max and Bmax,sensor. Also in the cleaning mode, if available, as described in the instructions for use.
Worst case assumption, calculated by taking formula C. The magnetic flux density is determined by using an averaging time of 1 s. For an arbitrary sensor area of Asensor the averaged magnetic flux density through it has to be calculated. In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested.
