Appendix I: Carbon Monoxide Room Safety Tests
Multiple Peaks of CO
The overall peak CO reading recorded will be the latest peak CO reading that
was higher than any previous. The peak duration recorded will be the total
time the CO readings exceeded the maximum allowed CO level. The pass / fail
criteria are applied as before based on this information. Sprint does not expect
to record multiple peaks of CO where the reading goes up and down more
than once.
Unstable or Rising Levels of CO
If there is a significant build up of CO levels at the end of the test and levels are
still rising the test will fail.
The result code is: FAILED (1)
CO Level Exceeds Max Allowable Level and Peaks for Unknown
Duration
If the CO level exceeds the maximum allowed too close to the end of the test
then the test is failed. This can occur if there is a build up of CO levels towards
the end of the test or the appliance fires up late on in the test or the test is
stopped too early. The test should be repeated if this occurs.
The result code is: FAILED (2)
CO Level Does Not Start Close to Zero
It is important that the instrument is zeroed in clean air at switch-on. Failure to
do so will invalidate the test result. BS 7967-2 also requires that the room is
well ventilated prior to starting the test. However it is possible that there may
be a residual background CO level (eg: due to traffic fumes). The instrument
will display a pop-up box prior to starting the test if the CO level is more than
3 ppm.1
