| Abstract |
Specifies the method of test for the determination of the proof and
comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. The standard provides for the determination of erosion when required. Test results cannot be used directly for the evaluation of safe
creepage distances when designing electrical apparatus.
Has the status of a basic safety publication in accordance with IEC
Guide 104.
Major changes since the previous edition are the following:
The selection of a material for a specific application frequently
involves compromises in the levels of the individual properties and
test criteria. In the previous edition of IEC 60112 the test
criteria required "no burning of the specimen", but this gave rise
to two issues:
- difficulties in the identification of burning which includes all
types of combustion, e.g. flaming, and smouldering in the situation
where scintillations had occurred giving rise in many cases to
carbon on the surface of the specimen, and
- a situation in which some product committees had found it
necessary to dispense with the "no burning" criterion in the
tracking tests which they replaced by flame tests on the final
product, thereby giving rise to two types of CTI/PTI with different
criteria.
This English-language version is derived from the original bilingual publication by leaving out all French-language pages. Missing page numbers correspond to the French-language pages.
The contents of the corrigenda of June 2003 and October 2003 have
