4 General requirement
This clause of Part 1 is applicable.
5 General conditions for the tests
This clause of Part 1 is applicable except as follows.
5.2 Replacement:
In general, eight samples are required for the tests.
The tests of 13.3 and of Clauses 15 and 16 are carried out on one sample.
The tests of 18. 101 and of Clause 30 are carried out on one sample.
The test of 21. 102 is carried out on two samples. One of these samples is also used for the test of 22.101.
The test of 22.103 is carried out on one sample.
The remaining tests are carried out on the sixth sample. The other two samples are required for incorporating into the test arrangement to create the necessary thermal environment.
NOTE 101 Additional samples can be necessary If tests have to be repeated.
Nine samples of modular heating units are necessary for the tests of 11.2.102.
Additional samples are necessary lithe tests 0118.102 are carried Out.
Additional samples can be necessary for testing different sizes of heating units
The test of 22.105 is carried out on the same sample as that used for the test of 13.2.
Two samples of the additional layer of material, of sufficient size to cover the heating unit. are required if the test 0(21. 104 is carried out.
5.3 Addition:
The test of 22. 105 is carried out after the test of 13.2.
5.6 Addition:
Thermostats sensitive to room air temperature or outdoor air temperature are short circuited.
However, the thermostat is not short circuited if it can be set so that it does not cycle.
5.10 Addition:
However, for flexible sheet heating elements that are cut on site, the tests are carried out after connecting the supply leads and protecting the edges in accordance with the instructions.

7 Marking and instructions
This clause of Part 1 is applicable except as follows.
7.1 Modification:
Instead of the marking of rated power input or rated current the following applies:
— heating units shall be marked with their rated power input:
— flexible sheet heating elements without connection between adjacent elements shall be individually marked with their rated power input:
— other flexible sheet heating elements shall be marked with their rated power input per metre length.
Flexible sheet heating elements shall be marked with their maximum current if
— the current can vary depending on the length of the flexible sheet heating element:
— other flexible sheet heating elements can be supplied through them.AS NZS 60335.2.96 pdf download.
