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.
The Manufacturer shall comply with the following condition of manufacture:
· IS GSM Modem (not part of this evaluation)
· 101624 Communications Interface
When the 101624 Communications Interface is used it provides external power. In this case the internal battery pack is not fitted.
The sensors, designated as either Combo Sensor P/N 8K-CS1, P/N 8K-CS2 or P/N 8K-CS3, are externally connected to the Monitor and the sensor cable can be extended up to 300 ft (91 m). They comprise a processor/signal conditioning board and piezoelectric transducers - these items are fully potted in either an ABS plastic enclosure, P/N 8K-CS1 and P/N 8K-CS2, or an aluminium enclosure, P/N 8K-CS3 (in this application, the construction of “CS1” and “CS2” are identical except for the frequency of operation of the crystals - one operates at 1 MHz and the other at 250 kHz).
