Good morning,

I have bought from a distributor of your material in Germany several units of the following box model Ex Raychem RPG Ex-GRJ03 - 120 x 122 x 90.

I wanted to know if I can do the machining and tapping of holes in M25 without losing its ATEX certification or what procedure should I follow in order not to lose its ATEX certification.

I am very interested in your response since I want to make a larger volume purchase of different models for our stock.

Sincerely
