2.5.2 IECEx certificate of conformity
The BTLs have been certified under certificate number
IECEx SIR 11.0048X. The current issue of the certificate
and further information can be found in the “Certified
Equipment Scheme” section at www.iecex.com.
The certificate number is indicated on the part label.
2.5.3 Special conditions (“X” symbol)
The “X” symbol indicates special conditions that must be
noted for safe operation:
– The permissible ambient temperature is limited to
–50 °C…+80 °C.
– The certification of this equipment relies upon the
following materials used in its construction:
– Flange – stainless steel
– Cover – stainless steel
– O-ring
If the equipment is likely to come into contact with
aggressive substances, then it is the responsibility of
the user to take suitable precautions that prevent it
from being adversely affected, thus ensuring that the
type of protection featured by the equipment is not
compromised.
Aggressive substances: e.g. acidic liquids or gases that
may attack metals, or solvents that may affect
polymeric materials.
Suitable precautions: e.g. regular checks as part of
routine inspections or establishing from the material’s
data sheets that it is resistant to specific chemicals.
– The picture of the product label in section 14.2 of this
document has to be checked for appropriate markings,
ratings, and manufacturer contact information.
2.5.4 Operator documents
Zone classification in the system is the responsibility of the
operator and must be documented in an explosion
protection document. This document must also contain
the hazard analysis and assessment, proof of training,
maintenance plans and other documents as required
under Directive 1999/92/EC.
We expressly recommend including the user’s guide in the
operator’s documentation. For safety reasons, it must be
taken over completely and without any changes.
