NOTES:
1. Ta≤ 50 ºC: 80% RH max
Ta> 50 ºC: Absolute humidity must be lower than the humidity of 85%RH at 50 ºC
2. Ta at -20 ºC will be < 48 hrs at 0 ºC will be <120 hrs when humidity is higher than 75%.
3. Background color changes slightly depending on ambient temperature. This phenomenon is reversable.
4. Ta ≤ 70 ºC: 75RH max
Ta > 70 ºC: abosolute humidity must be lower than the humidity of 75%RH at 70 ºC.
5. Ta at -30 ºC will be <48hrs, at 80 ºC will be <120hrs when humidity is higher than 75%.
