Cold and hot / high and low temperature / temperature shock is common in the mode of [high temperature → low temperature, low temperature → high temperature], which is also called [two box shock]. Another so-called [three box shock] process is [high temperature → normal temperature → low temperature, low temperature → normal temperature → high temperature]. A [over normal temperature] action is inserted between high temperature and low temperature to avoid adding a buffer between the two extreme temperatures. If you look at the specifications and test conditions, Generally, the high and low temperature will be extremely high and very low if there is a normal temperature condition. We can see that there are cold and hot / high and low temperature / temperature impact conditions at normal temperature when comparing military specifications with automobile specifications.
