MARKING FROM ATEX

Zone	Mining	0		1		2
Zone	Mining	Gas	Dust	Gas	Dust	Gas	Dust
Equipment group	I	II
Equipment category	M1 or M2	1G	1D	2G	2D	3G	3D

IGNITION PROTECTION TYPE

Non-electrical explosion protection is always assigned the marking code “h” irrespective of the version. JDN uses constructive explosion protection.

EXPLOSION GROUP

Mining	Gas		Dust
–	IIA	E.g. propane	IIIA	Flammable lint
	IIB	E.g. ethylene	IIIB	Non-conductive dust
	IIC	E.g. hydrogen	IIIC	Conductive dust

MAXIMUM SURFACE TEMPERATURE

Mining	Gases		Dusts
–	T1	450°C	T…°C
	T2	300°C
	T3	200°C
	T4	135°C
	T5	100°C
	T6	85°C

For areas with a risk of dust explosion, the maximum permissible surface temperature of the device is specified explicitly; for areas with a risk of gas explosion, the maximum surface temperature is divided into a temperature class.
