couplings are suitable for the use according to EC standard 94/9/EC.
1. Industry (with the exception of mining)
•
device class II of category 2 and 3 (
coupling is not approved for device class 1
)
•
media class G (
gases, fogs, steams
), zone 1 and 2 (
coupling is not approved for zone 0
)
•
media class D (
dusts
), zone 21 and 22 (
coupling is not approved for zone 20)
•
explosion class IIC (
explosion class IIA and IIB are included in IIC
)

Explanation:
The maximum surface temperatures result from each the maximum permissible ambient or operating temperature T
a
plus the
maximum temperature increase
Δ
T of 20 K which has to be taken into account.
1)
The ambient or operating temperature T
a
is limited to + 90 °C due to the permissible permanent operating temperature of
the elastomers used.
2)
The maximum surface temperature of 110 °C applies for the use in locations which are potentially subject to dust
explosion, too.
2. Mining
Device class I of category M2 (coupling is not approved for device category M1).
Permissible ambient temperature - 30 °C to + 90 °C.
