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 BA354NE loop powered Rate Totaliser and the
optional accessories have been issued with an
IECEx Certificate of Conformity number IECEx ITS
11.0016 that specifies the following certification
codes:
Ex nA ic IIC T5 Gc
Ex tc IIIC T80ºC Dc IP66
Ta = -40ºC to 70ºC
Note:
The specified operating temperature of the
BA354NE is –20 to +70ºC. At temperatures below –
20ºC the instrument will continue to totalise but the
display will not function.
The specified gas and dust 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 should
therefore be used for installations which are made
using the IEC Code of Practice IEC 60079-14.
However the local code of practice should always be
consulted.
