APPROVALS
9.1 MDR 0001030 GD
The GG2 Detector has be independently tested by the Mine Safety Technology Centre and several
reports for different gas types were used to register the product for use in NSW underground Coalmines.
The performance criteria assessed was taken from NSW Government Gazette No 52 of 26 June 2015,
which incorporates conformance to both AS/NZS 60079-29.1:2008 and AS/NZS 4641:2007
While the design order does incorporate conformance to the two Australian standards, there are sections
in the Design Order, which are to a lower standard to that of aforementioned standards;
Catalytic CH4 Detector - Long-term Stability Test
o
The Mine Safety Technology Centre was engaged to verify the performance of the
catalytic detector to AS/NZS 60079.29.1 and the NSW regulatory requirements. The test
report issued states compliance with the long-term stability test however; this test was
shortened from 33 days in total to 26 days in total.
Electrochemical O2 Detector - Cross Sensitivity Test
AS/NZS 4641 Electrical apparatus for detection of oxygen and other gases and vapours
at toxic levels
—General requirements and test methods, state that the concentration
indicated by the output signal shall not vary from the test gas concentration by more than
a volume fraction of ±0.3% v/v over the range 10% - 25% v/v oxygen, when exposed to
the standards nominated combinations of laboratory test gasses. However when
independently tested by MSTC the 0-25% range Oxygen Sensor - Electrochemical
(177872) was found to vary from the test gas concentration by a volume fraction ±0.4%
v/v oxygen when exposed to the test gas combination containing 10% Carbon Dioxide.
o
The warmup time is the time interval, (with the equipment in a stated atmosphere),
between the time when the equipment is switched on and the time when the indication
reaches and remains within the stated tolerances. The warmup time of the O2 detector for
a cold start is 30 Minutes.
