Ta > 50ºC: Absolute humidity must be lower than the humidity of 85% RH at 50ºC. Note 3: Ta at -20ºC will be < 48 hrs at 70ºC will be < 120 hrs when humidity is higher than 75%. Note 4: Background color changes slightly depending on ambient temperature. This phenomenon is reversible. Note 5: Ta 70ºC: 75% RH max. Ta > 70ºC: absolute humidity must be lower than the humidity of 75% RH at 70ºC. Note 6: Ta at -30ºC will be < 48 hrs, at 80ºC will be <120 hrs when humidity is higher than 75%.
