1. Environmental constraints
Equipment must be tropicalized when it is used or stored under the following environmental conditions: high temperature and humidity, significant temperature variations, dust and sandstorms, sunlight, presence of animals and pollutants.
High temperature and humidity
In "warm and temperate" climates, the average daily outdoor temperature is 30°C, but this generally does not exceed 20°C when relative humidity is over 95%. The corresponding absolute humidity is around 15 g.m –3 .
In "hot and humid" climates, absolute humidity reaches 30 g.m –3 as an average daily extreme value. On the other hand, at extreme values, maximum absolute humidity...
