#### Coefficient of Linear Thermal Expansion (CLTE): Formula ...

ASTM E289 provides a standard method for linear thermal expansion of rigid solids with interferometry that is applicable from –150 to 700 °C (–240 to 1290 °F). It is is more applicable to materials having low or negative CTE in the range of <5 × 10 -6 /K (2.8 × 10 -6 /°F) or where only limited lengths of thickness of other higher ...

The coefficient of thermal expansion of wood varies greatly depending on the type of wood and direction of the grain. Suppose that a wooden meter stick shrinks by 0.14 mm when it is taken to a 11.5 °C location for an outdoor lab experiment. If the inside temperature was 21 °C what is the meter stick’s coefficient of thermal expansion?

The coefficient of linear thermal expansion (CLTE) of any material is the change of a material's dimension per unit change in temperature. - special thanks to reader Eric P.E. The coefficient of thermal expansion or CLTE Coefficient of Linear Thermal Expansion. The linear expansion of a heated solid (or liquid) is measured by

#### Thermal Expansion: Table of Coefficient of Thermal ...

Definition of CLTE: The coefficient of linear thermal expansion (CLTE) of any material is the change in the material’s length [and to a much lesser degree the width or thickness] per unit change in temperature. CLTE applies to the length width and thickness equally not too a much lesser degree . If the width and thickness are smaller the expansion will be smaller however the ratio remains the same. I'd suggest …
