看了下ASTM F1980,
3.2 Definitions of Terms Specific to This Standard 里注释了ambient temperature (TRT) , n—storage temperature for real-time aging (RT) samples that represents storage conditions.
这样看关键应该是如何理解“represents”。
但后面 7.2 Accelerated Aging Plan-Design Guidelines中关于 TRT 的说明如下:
7.2.2 Room or Ambient Temperature (TRT)—Select a temperature that represents the actual product storage and use
conditions.
NOTE 2—This temperature is typically between 20 to 25℃. A temperature of 25℃ is considered a conservative approach.
可以看到备注里有关于TRT范围和25℃的补充说明。
