This test method covers the determination of the change of resistance with temperature of metallic materials for electrical heating, and is applicable over the range of service temperatures.
本试验方法适用于电热合金随温度变化的测量，亦可用于超过电热合金使用温度范围的情况。

Generally we considered the affection elements of the temperaturetest results, is the temperature, holding time, temperature change rate and so on.
通常认为，影响温度试验效果的要素有温度、停留时间、温变率等。

First, the time-drift of sensor's characteristic and its change law with temperature are obtained by the accelerated test, then the sample set is established.
