After placing an engine in an M.V.P envelope
- check humidity indicator after 12 hours.
- check humidity indicator after 24 hours.
- check humidity indicator after 48 hours.
Explanation
After sealing an engine in a marine vapour-proof (MVP) envelope the humidity indicator is allowed to settle and is checked after about 24 hours to confirm the desiccant has dried the trapped air to a safe level before the longer periodic checks begin.
