5 General notes on tests
Replace the existing Clause 5 by the following:
5 General notes on tests
Unless otherwise specified, all tests shall be carried out under the following atmospheric
conditions:
Temperature: 15 °C to 35 °C
Relative humidity: 25 % to 75 %
4 5
Air pressure: 8,6 × 10 Pa to 1,06 × 10 Pa
Where the above-mentioned conditions have a significant influence, they shall be kept
substantially constant during the tests.
If the temperature limits given in this clause are too wide for certain tests, these shall be
repeated, in case of doubt, at a temperature of (23 ± 1) °C.
In every test report, the ambient temperature shall be stated. If the standard conditions for
relative humidity or pressure are not fulfilled during the tests, a note to this affect shall be
added to the report.
If the result of a test is influenced, to an appreciate extent, by the position and method of
mounting of the specimen, the most unfavourable condition shall be chosen for the relevant
tests and recorded.
If a thermal-link has been specifically designed for use in a special type of equipment and
cannot be tested separately, the tests of this standard shall be performed in that equipment or
in the relevant part of it, or similar.
When testing a homogeneous series of thermal-links, all the tests shall be applied to thermal-
links with the lowest and highest T. Thermal-links with intermediate rated functioning
f
temperatures need only be subjected to tests according to 10.6, 11.2, 11.3 and 11.4.

60691 Amend. 1  IEC:2006(E) – 5 –
The total number of specimens required is 45. Out of a total of 45 specimens, 15 are kept as
spares in case some of the tests have to be repeated. Out of a total of 45 specimens, 30 are
divided into groups assigned an alphabetical letter from A to J. Each group consists of three
specimens. In general, tests shall be performed in the order indicated in Table 1 but, if so
required, tests may be repeated, for example the test on marking (see Clause 7). Additional
samples may be needed according to Note 2 of Table 1.
NOTE 1 For optional tests, additional samples will be required per the annexes.
If, in any of the tests carried out in accordance with any clause, a failure is reported, the
cause of the failure will be identified and corrective action taken. Based on the failure analysis
report and the corrective action, at a minimum, that test sequence shall be repeated on twice
the number of revised specimens and no further failures are allowed.
The conductive heat ageing test of Annex C is applicable when declared by the manufacturer.
Exception: The conductive heat ageing test may be omitted if the thermal-link is constructed
without contacts.
NOTE 2 In the USA the conductive heat ageing test is required to be declared.
