INTERNATIONAL ELECTROTECHNICAL COMMISSION
METHOD OF TEST FOR ELECTRICAL RESISTANCE AND RESISTIVITY
OF INSULATING MATERIALS AT ELEVATED TEMPERATURES
FOREWORD
1)The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the
National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
3) In order to promote this intern
ational unification, the IEC expresses the wish that all National Committees having as
yet no national rules, when preparing such rules, should use the IEC recommendations the fundamental basis for these
as
rules in so far
as national conditions will permit.
4) The desirability is recognized of extending international agreement on these matters through an endeavour to harmonize
national standardization rules with these recommendations in so far
as national conditions will permit. The National
Committees pledge their influence towards that end.
PREFACE
This Recommendation has been prepared by Sub-Committee 15A, Short-Time Tests, of IEC Technical
Committee No. 15, Insulating Materials.
A first draft was discussed at the meeting held in Venice in 1963. A new draft was discussed at the
meeting held in Tel-Aviv in 1966. As a result of this latter meeting, a final draft was submitted to the
National Committees for approval under the Six Months' Rule in September 1968.
The following countries voted explicitly in favour of publication:
Australia Korea (Democratic People's Republic of)
Belgium Netherlands
Canada Romania
Czechoslovakia South Africa
Denmark Sweden
Finland Switzerland
France Turkey
Germany Union of Soviet Socialist Republics

METHOD OF TEST FOR ELECTRICAL RESISTANCE AND RESISTIVITY
OF INSULATING MATERIALS AT ELEVATED TEMPERATURES
1. Scope
This test method covers procedures for the determination of insulation resistance and volume
resistivity of insulating materials at temperatures up to at least 800 °C.
The measurements shall be made in accordance with I E C Publication 93, Recommended Methods
of Test for Volume and Surface Resistivities of Electrical Insulating Materials, and with I EC Publi-
cation 167, Methods of Test for the Determination of the Insulation Resistance of Solid Insulating
Materials, utilizing the following special procedures.
