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 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.
TVOC is a wall mounted total volatile organic compound monitor and is designed to monitor the surrounding atmosphere for the presence of volatile organic compounds and provide both a local display of the concentration, and a corresponding 4-20mA signal for remote use.
It comprises electronic circuits and connectors on a PCB contained within an enclosure providing a degree of protection of at least IP20, together with a sensor mounted in a housing which protrudes from the bottom of the main enclosure. The sensor may be marked with Certificate numbers IECEx CSA 06.0006X or IECEx CSA 06.0005X.
For Connector J1 (Power Supply):Ui = 18V, Ii = 800mA, Pi = 1.2W, Li = 0 and Ci = 0
For Connector J2 (4-20mA Output):Ui = 30V, Ii = 200mA, Pi = 1.2W, Li = 0 and Ci =0.
Variation 1.1To permit minor changes to the 4-20mA circuit.
