Can anyone help?
We have an instrument which is made up of small PCB at intervals of 30cm to 50cm and connected by a few cables, housed in a stainless steel tube, and two layers of heat shrink and stainless steel braiding, it is not ATEX certified. It is powered by a 12 battery located in a safe area.
But we have found an ATEX IIC certified flameproof flexible conduit that is perfect for the instrument, which needs to be installed into a Zone 1 gas area.
What exactly do we need to do with the instrument (in terms of testing) to allow it to be used with the conduit? A DSEAR manager for the infrastructure claims that the conduit is only certified for cables but the manufacturers spec does not state this and neither does the ATEX cert.
The instrument itself must be suitable for use within a hazardous area i.e. have its own ATEX certificate unless it is housed within a certified explosion proof housing.
The cable transfer method is irrelevant.
I think you should consult a specialist consultant as this is an area with strict regulations and none compliance may lead to catastrophic accidents.
Try BSEN 60079 for more information on compliance.
Drop me a message if you require specialist information.
