SC 61C interpretation sheet on: Subclause 30.2 of IEC 60335-2-24:2010/AMD2:2017
Subclause 30.2 states:
"Add the following to the addition:
For accessible thermal insulation and non-metallic material on the external rear surfaces of an
appliance having an area exceeding 75 cm that is in direct contact with the thermal
insulation, compliance is checked by the test of 30.2.101."

Question 1: Has this subclause to be interpreted as:
"Add the following to the addition:
For accessible thermal insulation and non-metallic material on the external rear surfaces of an
appliance having a total area exceeding 75 cm that is in direct contact with the thermal
insulation, compliance is checked by the test of 30.2.101."
Subclause 30.2.101, final bullet point states:
• "that has an area not exceeding 75 cm that is in direct contact with the thermal
insulation is not tested. "
Question 2: Has this bullet point to be interpreted as:
• "that has a total area not exceeding 75 cm that is in direct contact with the thermal
insulation is not tested. "
Answers:
Question 1 –
From Subclause 30.2 addition, the following materials shall be tested:
1) Accessible thermal insulation
2) Non-metallic material on the rear surface of the appliance having an area exceeding
that is in direct contact with the thermal insulation
75 cm
Small holes (< 3 mm ) in the outer case were not intended to be considered as “accessible
thermal insulation”. These small < 3 mm holes are much smaller than the test probe B, so
therefore the thermal insulation of 3 mm holes is automatically not considered as accessible
thermal insulation without additional evaluation.
When testing accessible thermal insulation, the test is intended to be performed by applying
the flame to the accessible thermal insulation on the end product.
Question 2 – See question 1.
