TABLE OF CONTENTS Many industrial companies use separate steps, or several steps combined, but seldom full accelerated testing technology from the first to the last step. This is one of the basic reasons which these methods and equipment for AT often give low return benefits. The following UART technology can help to eliminate this problem.
It comprises the 11 basic steps that link with each other [11].
This step is very important, because it helps to convey the kind of input influences that act on the specific product in the field. To determine how they act, select the input influences that must be simulated in the laboratory for accurate UART. Without this knowledge one cannot substantiate accurate ART parameters and regimes.
For this goal it is necessary to obtain:
input influences which affect product reliability, durability, maintainability, etc. (the range, character, speed, and limit of value changing, etc. of temperature, air pollution, humidity, full complex of radiation, input voltage, air pressure, features of the road, etc.) under various field conditions wherever the product is employed, as it acts in the field.
input influences on the product in single steps and in simultaneous combinations including interaction, as they act in the field. An example is shown in Figure 2.10.

The basic meaning of this hierarchy is...
