This procedure is shown ied in Figure Z2. Appliances are considered to meet the requirements of this standard when all the following conditions are fulfilled: Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards.
Information regarding online access to British Standards via British Standards Online can be found at http: In case of measuring according to 5. Step 2 Determination of the equivalent coil Iwc measurement results from step 1 are used to determine the radius of an equivalent coil which gives a similar integral G.

For appliances with highly localised fields the coupling factor a c r 1 given in Annex C can be taken into account. Bioelectromagnetics, vol. Find Similar Items This product falls into the following categories. Standards are also available from the BSI website at http: This document addresses the additional measurement and calculation techniques which permit determination of compliance under one set of specified circumstance, without reference to time of exposure or actual exposure conditions.
Manufacturer’s ifc regarding short time operation have to be taken into account. It supersedes BS EN If these details 622333 to be used for any other purpose than implementation then the prior written permission of BSI must be obtained.
It is the constant aim of BSI to improve the quality of our products and services. The weighted result is obtained from the following formula: The simplest and more practical levels [limits] with which to comply are limits suitably timeaveraged in some cases on the electric E and magnetic B fields, measured in the absence of the human to be exposed to these fields.
