The factor k therefore calculates to 14,? Appliances may incorporate motors, heating elements or their combination, may contain electric or electronic circuitry, and may be powered by the mains, by batteries, or by any other electrical power source.
The induction heating units are operated in turn, the other cooking zones not being covered. NOTE 2 The final value of the magnetic flux density is the vector addition of the values measured in each direction. 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.
Generally applied methods are: Step 4 Calculation of the ic factor In case of measuring according to 5. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. The measurement methods specified are valid from 10 Hz to kHz. This can be achieved by recording the time signal of the flux density and using a Fourier transformation for evaluating the spectral components.
Independent of the type of the signal, a iex domain measurement of the value of the magnetic flux density can be carried out. Contact the Information Centre. However, only circular current loops were used as sources to calculate the coupling factors. Linear interpolation is used to obtain other values of r coil which shall not exceed lcoil.
It is recommended to use a small sensor, e. The start and finish of each common modification is indicated in the text by tags??. Appliances include such equipment as household electrical appliances, electric tools and electric toys.
Also in the cleaning mode, if available, as described in the instructions for use. We accept all major credit cards Lec Express, Mastercard and VisaPayPal and bank transfers as form of payment.
This will usually give a more realistic outcome than neglecting phase completely.

In consequence the factor ac r is frequency independent within these ranges see Figure C. 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 basic restriction for the current density is J BRthe basic restriction for the internal electric field strength is E BR ——————— 2 6233 be published. The value G is calculated from the following formula: Various BSI electronic information services are also available which give details on all its products and services.
EN 62233:2008 (IEC 62233:2005 (Modified))
To compare the measured values with limits, the reference level B RL j must be used. Florence Italy; http: NOTE Because of sharing power between 62233 heating units, the highest and continuous magnetic field is obtained when each heating units are operated separately.
It is incorporated by Royal Charter.

TC – Methods for the assessment of electric, magnetic and electromagnetic fields associated with human exposure rss.
In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Ief, unless otherwise requested.
The cabinet is empty. For appliances with highly localised fields the coupling factor a c r 1 given in Annex C can be taken into account. Oec using RF software codes, the application of a frequency scaling method  is possible: Existing exposure standards, e. BSI also holds the copyright, in the UK, of the publications of the international standardization bodies.
