Hello everyone,

I am new to the forum.
I would like to ask ,in what way is 25 cal/cm2 arc protected clothing possible to be classified 2.cat.

Thanks for your help
Tibor

70E Table 130.7(C)15(c) Personal Protective Equipment is the table used for the PPE Categories method. In that Table PPE 1 goes to 4 cals, PPE 2 goes to 8 cals, PPE 3 - 25 cals and PPE 4 - 40 cals.
Category 2 is good for 8 calories, but anything larger can be used for a lower incident energy rating, so a 25-cal PPE can be used for Cat 2.

Thank you for your reply,
So, a cloth is marked with 25 cal/cm and 2 CAT.
Which one is relevant?

Might be helpful to take a picture of the tag and post it here.

Does the garment have a tag on the inside, indicating its ATPV?

Yes,
ATPV25 cal/cm2
IEC61482 1-2
NFPA 70

The class 2 refers to APC 2 (Arc Protection Class 2) according to IEC61482-1-2 (european Box Test) and is independent from the ATPV value

Yes, it's clear.
I needed confirmation that I did indeed need to replace the protective clothing.
Thank you for the time you have spent on this topic

Sincerely
Tibor
