APPENDIX 2
IECEx Certification
A2.0 The IECEx Certification Scheme
IECEx is a global certification scheme for
explosion protected products which aims to
harmonise international certification standards.
For additional information about the IECEx
certification scheme and to view the BEKA
associate certificates, please visit www.iecex.com
A2.1 IECEx Certificate of Conformity
The BA448CF-F Fieldbus Indicator has been
issued with an IECEx Certificate of Conformity
number IECEx ITS 06.0013X which specifies the
following certification codes and marking:
Ex ia IIC T4 Ga
FISCO Field Device Ex ia IIC T4
Ta = -40
o
C to 70
o
C
See below for details of safe use in Zone 0.
CAUTION
Installation in Zone 0
When installed in a Zone 0 potentially
explosive atmosphere, the indicator shall be
installed such that even in the event of rare
incidents, an ignition source due to impact
or friction between the aluminium enclosure
at the rear of the instrument mounting panel
and iron/steel is excluded.
When connected to an IECEx certified system the
BA448CF-F may be installed in:
Zone 0
explosive gas air mixture
continuously present.
Note: Special conditions for
safe use apply see above.
Zone 1
explosive gas air mixture
likely to occur in normal
operation.
Zone 2
explosive gas air mixture not
likely to occur, and if it does will
only exist for a short time.
Be used with gases in groups:
Group A propane
Group B ethylene
Group C hydrogen
Having a temperature classification of:
T1
450oC
T2
300oC
T3
200oC
T4
135oC
At an ambient temperature between –40 and
+70
o
C.
Note: the guaranteed operating temperature range
of the BA448C Fieldbus Indicator is –20 to +70
o
C
The IECEx safety parameters are identical to the
ATEX parameters and, like the ATEX certification,
confirm that the BA448CF-F complies with the
FISCO Field Device requirements specified in
IEC60079-27.
The IECEx certificate may be downloaded from
www.beka.co.uk, www.iecex.com or requested
from the BEKA sales office.
A2.2 Installation
The BA448CF-F IECEx and ATEX certifications
have identical intrinsic safety parameters and
installation requirements. The ATEX system
design requirements described in section 4 of this
manual may therefore be used for IECEx
installations, but the local code of practice should
always be consulted.
