Question 20/V - Survey on provisions intended to mitigate adverse
effects
(danger and disturbance) of electromagnetic origin
(New Question)

Considering

- that adverse effects caused by electromagnetic fields are dealt with
in detail in several CCITT documents (Recommendations and Manuals);

- that some interdependence between effects generated by different
sources of inducing electromagnetic fields exists;

- that measures to mitigate adverse effects caused by one source may
influence such effects originated from other sources;

CCITT should establish guidelines on the following points in connection
with the application of relevant Recommendations and Manuals concerning
the mitigation of danger and disturbance:

1. classification of disturbances in telecommunication services and
danger to telecommunications equipment and personnel;

2. specification of the sources of danger and disturbance and ways to
control them;

3. tolerable levels of adverse effects;

4. reference to CCITT related documents.

Note - In the study of this Question, the work of IEC (CISPR and other
bodies) should be taken into account.
