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...
