Overview

This International Standard is part of a standard series dealing with tests of the electric strength of solid insulating materials. The series consists of three parts, with the following general title: Electric strength of insulating materials - Test methods: Part 1: Tests at power frequencies (IEC 60243-1); Part 2: Additional requirements for tests using direct voltage (IEC 60243-2); Part 3: Additional requirements for 1,2/50 µs impulse tests (IEC 60243-3). This part of IEC 60243 describes methods of test for the determination of the short-time electric strength of solid insulating materials at power frequencies, that is, those between 48 Hz and 62 Hz. This part does not consider the testing of liquids and gases, although these are specified and used as impregnates or surrounding media for the solid insulating materials being tested. Methods for the determination of breakdown voltages along the surfaces of solid insulating materials are included. Electric strength test results obtained in accordance with this standard are useful for detecting changes or deviations from normal characteristics resulting from processing variables, ageing conditions or other manufacturing or environmental situations; however, they can only be used in few cases for evaluating the behaviour of insulating materials in an actual application. The responsible committee is DKE/K 183 "Bewertung und Qualifizierung von elektrischen Isolierstoffen und Isoliersystemen" ("Evaluation and qualification of electrical insulating materials and systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
