Appendix I: Carbon Monoxide Room Safety Tests
NB: The alarm should prompt the operator to take appropriate action according to
BS7967 and safety procedures. The sensors in the instrument should be purged with
clean air and allowed to recover.
Unacceptable Levels of CO
A peak duration timer records whenever the CO level exceeds the maximum
allowed CO level during the test. If the total peak duration time exceeds the
max peak duration allowed then the test fails due to unacceptable levels of CO.
The result code is: FAILED (2)
Operator Pass/Fail Cases
The following results are considered to be operator determined whether the
test passes or fails:
Acceptable Levels of CO with no Peak
For some appliances CO levels may rise to a value beneath the specified limit
and stabilise rather than fall. In this case it is up to the operator to determine
PASS or FAIL.
If operator chooses to fail the test, the result code is: FAILED (4) otherwise the
result code is: PASSED (2)
CO Level Exceeds Max Allowable Level for a Short Duration
For some appliances (eg: cooker) a peak exceeding the maximum allowed CO
level may be acceptable, provided the CO level falls back below this level within
the max peak duration time. It is up to the operator to determine if the result
is acceptable or not.
If the operator chooses to fail the test, the result code is: FAILED (4)
Otherwise the result code is: PASSED (2)
Other Cases
When a test is not performed correctly, the results are inconclusive or there is
insufficient or unreliable data Sprint attempts to interpret the readings detected
and fail the test. It is possible for the results of a test to appear to be valid when
it was performed incorrectly or the data collected was unreliable in some way.
Please refer to BS7967 and ensure tests are carried out correctly. Sprint V tries
to reject incorrectly taken test readings but should not be relied on to instruct
engineers on correct working practice.
