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 BA358E loop powered Rate Totaliser and the
optional accessories have been issued with an
IECEx Certificate of Conformity number
IECEx ITS 11.0015X which specifies the following
certification codes:
Ex ia IIC T5 Ga
Ex ia IIIC T80ºC Da
Ta = -40ºC to 70ºC
The specified gas and dust intrinsic safety
parameters are identical to the ATEX safety
parameters described in 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 / EN 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 Special conditions for safe use
The IECEx certificate has an ‘X’ suffix indicating
that special conditions apply for safe use.
WARNING
To avoid an electrostatic charge being
generated instrument enclosure should
only be cleaned with a damp cloth.
A2.3
Special conditions for use in IIIC dusts
The IECEx certificate has an ‘X’ suffix indicating
that special conditions apply for safe use. In
addition to the electrostatic special conditions
specified in section A2.3 for installations in IIIC
dust atmospheres, the certificate states:
‘For use in Group IIIC conductive gas
atmospheres, the Rate Totaliser shall be
mounted such that the instrument
terminals have at least IP6X protection.’
To prevent the instrument terminals becoming
contaminated by conductive dust the BA358E must
be installed in a panel, cubicle or enclosure
providing a minimum of IP6X protection.
The gasket supplied to seal the joint between the
indicator and the mounting panel should be used
and the BA358E should be secured with four panel
mounting clamps.
Note:
These additional special installation
conditions only apply for indicators exposed to IIIC
conductive dust atmospheres.
