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 BA354E loop powered Rate Totaliser and the
optional accessories have been issued with an
IECEx Certificate of Conformity number
IECEx ITS 11.0014X which specifies the following
certification codes:
Ex ia IIC T5 Ga
Ex ia IIIC T80ºC Da IP66
*
Ta = -40ºC to 70ºC
* IECEx dust certification is an option, which if
required should be specified when the Rate
Totaliser is ordered.
CAUTION installation in Zone 0
When installed in a Zone 0 potentially explosive
atmosphere requiring EPL Ga apparatus, the
instrument shall be installed such that even in
the event of rare incidents, an ignition source
due to impact or friction between the aluminium
label and iron/steel is excluded.
No special conditions apply when the indicator is
installed in Zone 1 or in Zone 2.
The specified IECEx gas and dust intrinsic safety
parameters are identical to the ATEX safety
parameters described in the main section and
Appendix 1 of this manual.
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 IECEx and ATEX certificates specify identical
safety parameters and installation requirements for
both approvals as defined by IEC 60079-14. The
ATEX installation requirements specified in the
main section and Appendix 1 of this manual may
therefore be used for IECEx installations, but the
local code of practice should also be consulted.
A2.3 Versions of the BA354E
All versions of the BA354E loop powered Rate
Totaliser have IECEx certification.
This includes:
ATEX version for use in gas atmospheres.
IECEx code Ex ia IIC T5 Ga
Ta = -40ºC to 70ºC
ATEX version for use in gas and dust
atmospheres.
IECEx code Ex ia IIC T5 Ga
Ex ia IIIC T80ºC Da IP66
Ta = -40ºC to 70ºC
Note: The specified operating temperature of the
BA354E is –20 to +70ºC. At temperatures below
–20ºC the instrument will continue to totalise but
the display will not function.
CAUTION
Before installing a BA354E Rate Totaliser
in the presence of a combustible dust
atmosphere, ensure that the certification
information label which is located on the
top of the instrument specifies dust
certification, see section A1.2
