The following test report forms are related: It has the status of a horizontal standard in accordance with IEC Guide uec TC – Insulation co-ordination for low-voltage equipment rss. For type 2 protection this question is under consideration.

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. This part also applies to Part 3 for frequencies greater than 30 kHz and protection of type 1.

Preview Iiec IEC The dimensioning values directly apply for basic insulation; for reinforced insulation additional requirements apply according to Part 1. Applies to equipment for use up to 2 m above sea level having a rated voltage up to a. The minimum clearances specified in this part do not apply where ionized gases occur.

The object of this standard is to guide technical committees responsible for different equipment in order to idc 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. The dimensioning values directly apply for basic insulation; for reinforced insulation additional requirements apply according to Part 1.

Develop, test and integrate batteries according to the standards

The major changes made during the revision of IEC were the following: In normal use of equipment, it is assumed that the interference of high-frequency 6664-4 emitted to the mains is negligible with respect to insulation stress. We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment.

Consideration of high-frequency voltage stress. It applies to equipment for use up to 2 m above sea level having a rated voltage up to a. NOTE 2 This standard does not consider the high-frequency emission to the mains. Do you need a multi-user copy? This part also applies to Part 3 for frequencies greater than 30 kHz and protection of type 1.

Related publications IEC This part of IEC deals with basic, supplementary and reinforced insulation subjected to high-frequency voltage stress within low-voltage equipment. Insulation coordination for equipment within low-voltage systems — Part 4: 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.

This part does not deal with distances – through liquid insulation, – through gases other than air, – through compressed air. Our prices are in Swiss francs CHF. Therefore it is not necessary to take it into account. It is applicable for the dimensioning of clearances, creepage distances and solid insulation stressed by any type of periodic voltages with a fundamental frequency above 30 kHz and up to 10 MHz.
