onds closely to the average thermal resistance over a 15-year service life (7, 8).
It is recommended that any material standard that refers to C1303 to provide a product rating for long-term thermal resistance specify the Part A Test Method of C1303.
The Research Method in Part B provides a relationship between thermal conductivity, age, and product thickness. The calculation methods given in Part B can be used to predict the resistance at any specific point in time as well as the average resist
