Abstract

Provides basic guidance on the special aspects of the effects of electrical currents on persons for the establishment of electrical safety requirements. This Standard has been reproduced from and is technically identical with IEC 60479-2:1987.

Scope

This chapter describes the effects of sinusoidal alternating current within the frequency ranges:
– above 100 Hz up to and including 1 000 Hz (see clause 4);
– above 1 000 Hz up to and including 10 000 Hz (see (clause 5);
– above 10 000 Hz (see clause 6).
