This part also applies to Part 3 for frequencies greater than 30 kHz and protection of type 1. Skip to main content. NOTE 2 This standard does not consider the high-frequency emission to the mains.

For type 2 protection this question is under consideration. In normal use of equipment, it is assumed that the interference of high-frequency voltages emitted to the mains is negligible with respect to insulation stress.

The minimum clearances specified in this part do not apply where ionized gases occur. The dimensioning values directly apply for basic insulation; for reinforced insulation additional requirements apply according to Part 1.

Therefore it is not necessary to take it into account. This part does not deal with distances – through liquid insulation, – through gases other than air, – through compressed air.

This part of IEC deals with basic, supplementary and reinforced insulation subjected to high-frequency voltage isc within low-voltage equipment.

Specifies the requirements for clearances, creepage distances and solid insulation for equipment based upon their performance criteria. TC – Insulation co-ordination for low-voltage equipment rss. By using Part 1 or Part 5 together with this part the frequency limit of Part 1 or Part 5 is extended to frequencies higher than 30 kHz. Applies to equipment for use up to 2 m above sea level having a rated voltage up to a.

The major changes made during the revision of IEC were the following: Insulation coordination for equipment within low-voltage systems — Part 4: This part also applies to Part 3 for frequencies greater than 30 kHz and protection of type 1.

It applies to equipment for use up to 2 m above sea level having a rated voltage up to a. Related publications IEC It has the status of a horizontal standard in accordance with IEC Guide Preview Abstract IEC The dimensioning values directly apply for basic insulation; for reinforced insulation additional requirements apply according to Part 1. Consideration of high-frequency voltage stress.

The object of this standard is to guide technical committees responsible for different equipment in order to rationalise their requirements so that insulation coordination is achieved when specifying clearances in air, creepage distances and solid insulation for equipment. For type 2 protection this question is under consideration.
