Evidence of cold starting conditions on day one, the 2
nd
of September 2020 to ASTM E3053 clause 8.5.1
(Ambient temp was 24,0 degr C at 12:19:15 hours)
Based on the evidence presented above and, DTI declares test runs #1 (Cold start and High fire 1 test)
and #2 (Low fire test) was determined to be conditional and appropriate. Because the filter clogged and
sampling had to be suspended temporarily during test run #1,
we exclude test run #1, meaning it will
not be used for the average result calculations
. Test run #2 however is deemed valid in any respect.
Please also see section 3.9 Anomalies for further discussion of the test run #1 filter clogging incident.
