Accelerated life testing is the process of testing a product by subjecting it to conditions (stress, strain, temperatures, voltage, vibration rate, pressure etc.) in excess of its normal service parameters in an effort to uncover faults and potential modes of failure in a short amount of time.
The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation).

This type of test is, however, a subject of frequent criticism. [2] There is no single recommended set of conditions at which these tests should be performed. In fact, temperatures from 22 to 160 degrees Celsius, relative humidities from 1% to 100%, and test durations from one hour to 180 days have all been used. [2]
The reliability test duration assures the device's adequate lifetime requirement. For example, with an activation energy of 0.7 eV, 125 °C stress temperature and 55 °C use temperature, the acceleration factor (Arrhenius equation) is 78.6. This means that 1,000 hours' stress duration is equivalent to 9 years of use.

The short answer is probably not, but it depends on the situation. It's important to know the risks about consuming cracked eggs. Let's see what the experts ( eggs -perts, if you will) have to say.
The holiday season is incomplete for many people without holiday movies. This year, Netflix is streaming a wide range of Christmas classics and original movies.
