I'm lost and looking for just a quick sanity check. We normally don't
need to comply with these specifications so I don't yet have the underlying
standards IEC60068-2-14 method Nb, for example.
Table 5 of the ETSI test spec for air temperature says for air/air
Test Severity is -40/+30 and a 1C/min change.
The duration says 5 cycles T1 = 3h
Assuming by cycle they mean up and back that only accounts for 140
minutes out of the 210 minutes in the 3 hour test cycle. Are they trying to
tell me that there is a dwell time and teach level, of about 35 minutes each.
That at least accounts for the missing 70 minutes?
