This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
This Unit verification certificate is issued as verification that the Apparatus identified on page 1, was assessed and tested and found to comply with the IEC Standard list below. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
STANDARDS: The electrical apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
Model No
The enclosure consists of a cast aluminium base (Type A360) into which is housed the light/electronic modules. Onto this is fitted a dome assembly which consists of a glass dome cemented into an aluminium ring housing forming a cemented flamepath. A flange flamepath is formed between the dome assembly ring and the enclosure base which is then secured using six M10x1.5 hex socket head fasteners. Cable entry is via two M25x1.5 threaded holes which must be fitted with suitably certified cable glands or blanking elements. Both internal and external earthing points are provided via M6 threaded studs with associated nuts and locking washers. Dimensions: Overall Height = 149.81mm, Base Diameter = 252.48mm.
(a). Special Conditions for safe use
i. No modifications must be made to the flamepaths of the unit without consultation of the drawings listed on IECEx Ex Test Report Cover GB/ITS/ExTR10.0039/00.
ii. Temperatures could exceed 70°C at the cable gland or 80°C at the branching point, suitably rated cable must be selected.
iii. Potential electrostatic charging hazard – clean glass dome only with a damp cloth.
iv. For securing glass dome cover to base use only M10x1.5 hex socket head fasteners with yield stress ≥450N/mm2.
(b). Conditions For Use (Routine Tests)
A routine overpressure test in accordance with EN 60079-1:2007 shall be carried out on each enclosure (including the cemented glass dome assembly) at the following pressure and must be recorded. There shall be no leakage through the cement and no deformation or damage to the enclosure:
For lower ambient of -20°C – 10.16bar
For lower ambient of -40°C – 14.73bar
Inclusion of an o-ring between the Dome Cover and Base.
