IEC 61010-1 Clause No. 10.5 Resistance to Heat - Sub Clause 10.5.3 Insulating Material

Hello Everyone,

I am having confusion regarding sub-clause 10.5.3 Insulating Material that this explains the requirement of heat resistance of terminal insulation or does it also includes the material of the enclosure body in its criteria? I do have the confusion because there is a separate sub-clause given as 10.5.2 for the Non-metallic enclosures in the same 10.5 clause which states a different testing condition for the enclosure material.

So, It seems like the requirement for the heat resistance for both the terminals & enclosure body are different.

I might be misinterpreting it. If so please do let me know.

Just to summarise: 10.5 applies to non-metallic enclosures:
10.5.1 requires clearance and creepage distances of 6.7 to be met immediately following the heat treatment in para (a) or (b)
10.5.2 requires enclosure rigidity tests of Clause 8.2 and 8.3 to be met immediately following the heat treatment in para (a) or (b)
10.5.3 applies to insulators in mains circuits

Yes, the temperature in 10.5.3 is higher as it foresees local heating due to poor contacts - it requires a plastic to have a higher softening temperature than would be acceptable for the enclosure

The temperature mentioned in the standard is 125°C for the ball pressure test. So that means the plastic material which we need to use for manufacturing an enclosure should have higher melting or softening temperature than that right?

Only plastic parts that hold conductors in mains circuits need to meet the ball pressure test of 10.5.3, the main enclosure does not and (only) has to meet 10.5.2

In our case, the mains circuit is connected to the PCB & PCB has been mounted on the product enclosure body. What would be applicable in this scenario?

Assuming the mains input is a certified IEC socket, or similar, that will be fine
In my experience a UL recognised PCB material will also be fine
From your description, the enclosure does not need to meet 10.5.3
