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.
The 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.
The Z Series Diode Safety Barriers are designed to restrict the transfer of energy from unspecified non-intrinsically safe circuits to intrinsically safe circuits by the limitation of voltage and current.
The series comprises single, dual or triple output shunt diode barriers in a single unit. Each barrier consists of fuse protected, triplicated zeners with resistive output current limitation. Components on which Intrinsic Safety depends are encapsulated.
Models covered by this certificate are listed in the Annex.
