APPENDIX  3
IECEx Certification

A3.0   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    

A3.1  IECEx Certificate of Conformity

The BA444DF-P Fieldbus Indicator and has been
issued  with  an  IECEx  Certificate  of  Conformity
number IECEx ITS  06.0012X which specifies the
following certification codes:  

For gas
Ex ia IIC T4 Ga
Ex ic IIC T4 Gc
FISCO Field Device Ex ia IIC T4
Ta = -40°C to 70°C

For dust
Ex ia IIIC T100°C Da IP66
Ex ic IIIC T100°C Dc IP66
Ta = -20°C to 60°C

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.

A3.2  Installation

The IECEx and ATEX certificates specify identical
safety parameters and installation requirements for
both  gas  and  dust  approvals.    The  ATEX
installation  requirements  specified  in  the  main
section  and  in  Appendix  1  of  this  manual  may
therefore be used for IECEx installations, but the
local code of practice should also be consulted.

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.

A3.3  IECEx Dust certification

If  IECEx  dust  certification  is  required  it  must  be
requested when the BA444DF-P Fieldbus Indicator
is purchased. 

CAUTION

Before  installing  a  BA444DF-P  Fieldbus
Indicator  in  the  presence  of  a  combustible
dust, ensure that the certification information
label,  which  is  located  on  the  top  of  the
instrument,  specifies  dust  certification  -  see
below.

A3.4  Versions of the BA444DF-P

All versions  of the BA444DF-P Fieldbus  Indicator
have IECEx certification.   This includes: 

ATEX version for use in gas atmospheres.

ATEX  version  for  use  in  gas  and  dust
atmospheres has IECEx gas & dust certification.

Factory Mutual Approved version
