STANDARDS AND CERTIFICATES

STANDARDS AND CERTIFICATES
ATEX and IECEx brakes are approved for the following areas:

GAS

II 2 G Ex d II P 1 T P 2 Gb Tamb.: -50°C ÷ +55 (for T5 Tamb: +60°C) or -20°C ÷ +55 (for T5 Tamb: +60°C).

DUSTS
II 2 D Ex tb IIIC T P 3 Db IP66 Tamb.: -50°C ÷ +55 (for classe T100°C Tamb: +60°C) or -20°C ÷ +55 (for class T100°C Tamb: +60°C).

GAS and DUST
II 2 GD Ex d II P 1 T P 2 Gb. Ex tb IIIC T P 3 Db IP66
Tamb.: -50°C ÷ +55 (for class T5 or T100°C Tamb: +60°C) or -20°C ÷ +55 (for class T5 or T100°C Tamb: +60°C).

I M2 Ex d I Mb Tamb.: -50°C ÷ +55°C oppure -20°C ÷+55°C

Pn are subjected to the following variations:

P1 for GAS groups if:
P1 = B: gas group IIB P1 = C: gas group IIC.

P2/P3 for temperature classes/surface temperature:
P2 = T3 P3 = T200°C P2 = T4 P3 = T135°C P2 = T5 P3 = T100°C
50°C ÷ + 55°C (for class T5 o T100°C Tamb: +60°C) = Amb Temp.
20°C ÷ + 55°C (for class T5 o T100°C Tamb: +60°C) = Amb temp for frames IEC 250/280/315

T. cable: 80°C = Cable temperature

Notes:
INMETRO, KTL, TCRU approvals are related to IECEx specification.
