Does anyone know if there are any mandatory standards regarding the voltage of the sight glass lights in reaction vessels in Class A factories? ? Thank you!

GB3836—2000, IEC60079. Below 36V, the most commonly used are 12V explosion-proof peephole lights.

Could you explain in detail which standard within 3836 this refers to?

Whether in an explosion-proof area or not, the voltage of the sight glass lights must be below the safe voltage of 36V. In explosion-proof areas, it is required to use explosion-proof peephole lights EX

Thank you for your reply! I would like to know which standard specifies this safe voltage of 36V; could you share it with me?
