Specifies methods for the measurement of power-frequency electric field strength in air using commonly available or commercially available instrumentation, and procedures for calibration. This Standard is technically identical with and reproduced from IEC 833:1987.

This standard is applicable to the measurement of electric field strength at power frequencies in air for quasi-uniform electric fields with instrumentationin common use and/or commercially available. The standard is applicable to other instruments provided they are calibrated according to the procedures described in this standard.
