Hello Mr. @Barley_Li and the DigiKey community,
We have been working with your components for several years now and I saw that you were very active on the Digikey forum, particularly in terms of standards (IEC 61010-1, IEC 61010-2-032, 031 etc.)
So I have a question…
We will update our products according to the latest IEC 61010-2-032: 2023
And in this one since 2019 there has been an update where it is written, I quote:
“Reduced creepage distances can comply with material group I for all insulating materials. »
This is subject to interpretation, I need your thoughts on the top.
Suppose I have a measuring device that is 1000V CAT III pollution grade 2 that is in the final stages of finalization for test passes for the IEC.
The device is made of category III materials because we cannot find the indication of its CTI.
So it corresponds to table K.3 of 61010-1:
But following the 2019 update:
“Reduced CREEPAGE DISTANCES are allowed to be according to material group I for all insulating materials. »
Can we say that the creepage distance can go from 10 to 8 mm?
Thank you all for taking the time to read me, and if you have any information don’t hesitate, have a good day
