The running-in time jec not specified but, prior to testing, the appliance is operated for a sufficient period to ensure that the conditions of operation are typical of those during normal use. Internationally accepted SI-units are used throughout the standard. The following dates are applicable: This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. Appliances are considered to meet the requirements of this standard when all the following conditions are fulfilled: Information on standards BSI provides a wide range of information on national, European and iev standards through its Library and its Technical Help to Exporters Service.

To compare the measured values with limits, the reference level B RL j must be used.

NOTE Because of sharing power between induction heating units, the highest and continuous magnetic field is obtained when each heating units iex operated separately. Worldwide Standards We can source any standard from anywhere in the world.

For calculation methods, IEC can be used. This European Standard supersedes EN 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. 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.

If it is not feasible to 622233 the frequency range in one measurement, the weighted results of each measured frequency range shall be added. With appliances with highly localized fields, this has to be performed after taking the coupling factor ac r1 given in Annex C into account. You may experience issues viewing this site in Internet Explorer 9, 10 or It shall be verified, e.

EN 62233:2008 (IEC 62233:2005 (Modified))

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. For fields with several frequency proportions the calculation of a frequency weighted sum is necessary. Linear interpolation is used to obtain other values of r coil which shall not exceed lcoil.

Suitable definitions and specified measurement techniques are applied in any exposure compliance measurement or assessment. It supersedes BS EN Various BSI electronic information services are also available eic give details on all its products and services. This calculation yields the electric lec strength E’ at the frequency f ‘. For equipment for which it is not practical to test with each function operated separately, or where the separation of a particular function would result in the equipment being unable to fulfil its primary function, the equipment shall be operated with the minimum number of functions needed to operate.

NOTE 1 For small appliances, the magnetic field source is assumed to be at the centre of the appliance. We use cookies to make our website easier to use and to better understand your needs. NOTE These limits do not apply for the protection of workers against exposure to electromagnetic fields.

However, pre-set controls are used in the intended position.

Manufacturer’s specifications regarding short time operation have to be taken into account. Existing exposure standards, e. Numerical evaluation of 60 Hz magnetic induction in the human body in complex occupational environments.

The part in the middle is ied cylinder with a diameter of mm and for the head and shoulders the details are shown in Figure D. The measurements are made up to 1 m above the cooking zone and 0,5 m below it. NOTE 2 The final value of 6223 magnetic flux density is the vector addition of the values measured in each direction.

Appliances include such equipment as household electrical appliances, electric tools and electric toys.

The result is the weighted r.
