PLTL-12 Coefficient of Linear Expansion
Solid materials such as epoxys, plastics and metals will expand when heated. In systems with tight tolerances, accommodations for this expansion must be considered. This test determines the Coefficient of Linear Expansion, which quantifies the increase in length due to this expansion.
The sample length is determined at one temperature, the sample is heated and the length is determined at a second temperature. The coefficient of linear expansion is calculated as the change in length per length per degree temperature. Please indicate the temperature range of interest.
