The output from the EMFWELD® software has been validated for the geometries and types of equipment described in the software documentation and has been demonstrated to provide results in agreement with alternative measurements for those geometries and processes. In the case of end user assessment scenarios, you should be aware that when significant differences are present between the development and testing scenarios that the accuracy of calculated exposures is likely to be reduced.

Information is provided in good faith and in conformance to the requirements of the EMF Directive 2013/35/EU. However, the Licensee should be aware that National Implementations may use alternative words and phrase.

It is an offence to reproduce or distribute this software or parts thereof without authorisation from the owner. Such actions can lead to criminal or civil proceedings that may result in severe penalties or damage claims.
