What is tropicalization? IEC 60068-1 Environmental testing, General and guidance

Tropicalization

Protection of Electric Equipment from the surrounding atmospheric conditions such as humidity, heat, cold, fungal attack, salt spray is known as the tropicalization of Electric Equipment.

The families of tests comprising Part 2 of the IEC 60068 series are designated by the

following upper-case letters:
A: Cold
B: Dry heat
C: Damp heat (steady-state)
D: Damp heat (cyclic)
E: Impact (for example shock and rough handling shocks)
F: Vibration
G: Acceleration (steady state)
H: (Awaiting allocation)NOTE 2 Originally allotted to storage tests.
J: Mould growth
K: Corrosive atmospheres (for example salt mist)
L: Dust and sand
M: Air pressure (high or low)
N: Change of temperature
P: (Awaiting allocation)NOTE 3 Originally allotted to "flammability".
Q: Sealing (including panel sealing, container sealing and protection against ingress and
leakage of fluid)
R: Water (for example rain, dripping water)
S: Radiation (for example solar, but excluding electromagnetic)
T: Soldering (including resistance to heat from soldering)
U: Robustness of terminations (of components)

U: Robustness of terminations and integral mounting devices
Test Ua: Subdivided as Test Ua 1 : Tensile; and Test Ua 2 : Thrust
Test Ub: Bending
Test Uc: Torsion
Test Ud: Torque

V: (Awaiting allocation)NOTE 4 Originally allocated to "acoustic noise" but "vibration, acoustically induced" will now be Test Fg,
one of the "vibration" family of tests.
W: (Awaiting allocation)
Y: (Awaiting allocation)
