Some further recommendations
IEEE 43 – 2000 Recommended Practice for Testing Insulation Resistance of Rotating
Machinery:

1 M Ω + 1 M Ω / 1000 V rating of equipment for insulation systems prior to 1970;

5 M Ω for random wound motors under 600 Volts;

100 M Ω for form wound motors over 600 Volts, and armatures;
IEC 60439-1 Low-voltage switchgear and control gear assemblies - Part 1:
Type-tested and partially type-tested assemblies:

Scope of the insulation resistance test: alternative method for verification of
dielectric properties by insulation resistance measurement;

Description: a d.c. test voltage (500 V) is applied to the insulation and its
resistance is measured. Insulation is proper, if its resistance is high enough (1000
Ω / V of circuit rated voltage);
IEC 61558 Isolating transformers and safety isolating transformers:

Test voltage: 500 V, measurement period: 1 min;

Minimum insulation resistance for basic insulation: 2 M Ω ;

Minimum insulation resistance for supplementary insulation: 5 M Ω ;

Minimum insulation resistance for reinforced insulation: 7 M Ω ;

IEC 62133 Secondary cells and batteries containing alkaline or other non-
acid electrolytes - Safety requirements for portable sealed
secondary cells, and for batteries made from them, for use in
portable applications.
Note:
Immunity to radiated RF fields (Field strength: 10V/m, Modulation: AM, 80%, 1 kHz)
Voltage Range Operational conditions Disturbance < 5 % Disturbance > 5 %
50 V 100 M Ω 300 MHz ÷ 900 MHz 900 MHz ÷ 1 GHz
Note about EN and IEC standards:

Text of this manual contains references to European standards. All standards of
EN 6XXXX (e.g. EN 61010) series are equivalent to IEC standards with the same
number (e.g. IEC 61010) and differ only in amended parts required by European
harmonization procedure.
