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 BA307E, BA327E, BA308E and the BA328E
loop powered indicators 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 gas and dust installation requirements
specified in section 5 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 use in IIIC dusts
The IECEx certificate for the loop powered
indicators has an ‘X’ suffix indicating that special
conditions for safe use are required for installion in
IIIC dust atmospheres, the certificate states:
‘For use in Group IIIC conductive gas
atmospheres, the indicator shall be
mounted such that the instrument
terminals have at least IP6X protection.’
To prevent the indicator terminals becoming
contaminated by conductive dust:
The indicator 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 must be used, and the 144 x 72mm
BA308E and BA328E indicators must be
secured with four panel mounting clamps.
Note: These special installation conditions only
apply for indicators exposed to IIIC conductive dust
atmospheres.
