Generally applied methods are: 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. For further calculations it is assumed that this coil is positioned at a distance l coil from the hot 622233corresponding to the location of the magnetic field source inside the appliance see Figure C.

A step by step procedure can be applied, from the easiest methods to the more complicated ones, see the flow diagram in Figure 1.

If no recommendations are provided, the smallest standard vessel that covers the marked cooking zone is used. The bottom diameters irc standard cooking vessels are: 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.

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.

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. This standard does not apply to: NOTE 2 The final value of the magnetic flux density is the vector addition of the ifc measured in each direction.

The source current I Q can be chosen arbitrarily but should be equal for the calculation of J max and Bmax,sensor. For undated references, the latest edition of the referenced document including any ie applies. See Scope Clause 1. It presents the UK view on standards in Europe and at the international level.

If it is not feasible to cover the frequency range in one measurement, the irc results of each measured frequency range shall be added. BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards. Electrical household appliances, Household equipment, Electrical equipment, Electromagnetic fields, Electric fields, Magnetic fields, Electromagnetic radiation, Field strength electricMagnetic flux density, Electrical testing, Electrical measurement, Physiological effects 622233 bodyElectrical safety, Equipment safety, Mathematical calculations.

The field distribution from the hot spot with Bmax to 0,1 Bmax shall be continuous.

For an arbitrary sensor area of Asensor the averaged magnetic flux density through it has to be calculated. Except as permitted under the Copyright, Designs and Patents Act no extract may be reproduced, stored in a retrieval system or transmitted in any form or by any means — electronic, photocopying, recording or otherwise — without prior written permission from BSI. For fields with several frequency proportions the calculation of a frequency weighted sum is necessary.

Compliance with maximum permissible exposure or reference levels is sufficient for positive assessment of meeting these levels as specified in the appropriate exposure standard. We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover.

For calculation methods, IEC can be used. This calculation yields the electric field strength E’ at the frequency ic ‘. Buying standards Orders for all Uec, international and foreign standards publications should be addressed to Customer Services. 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 magnetic flux density is determined by using an averaging time of 1 s.

This is the reference method, which has to be used in case of dispute. Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards.

If a switching action occurs during the measurements, the measurement has to be repeated. Kleinheubacher BerichteBandpp. The final weighted result, W, can be derived as follows: For details of these and other benefits contact Membership Administration. Take the smart route to manage medical device compliance. For this step it is important to know the distance lcoilwhich depends on the size of the measured household appliance.

Florence Italy; http: 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.

This ensures that the measured value is independent of the direction 6233 the magnetic field vector. The evaluation of the factor k depends therefore on the sensor used. Numerical calculation of current densities induced in the human body caused by low frequency inhomogeneous magnetic sources.

The measurement methods specified are valid from 10 Hz to kHz. Suitable definitions and specified measurement techniques are applied in any exposure compliance measurement or assessment.
