Frequently Asked Questions

Q: What is thermal expansion testing?
Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature.

Coefficients of linear thermal expansion (CTE) are required for design purposes and are used, for example, to determine dimensional behavior of structures subject to temperature changes, or thermal stresses that can occur and cause the failure of a solid artifact composed of different materials when it is subjected to a temperature excursion.

Q: How to test for thermal expansion?
This test method covers the determination of the linear thermal expansion of rigid solid materials using push-rod dilatometers. This method is applicable over any practical temperature range where a device can be constructed to satisfy the performance requirements set forth in ASTM E-228 standard.

Thermtest offers thermal expansion testing services. Our thermal expansion measurement method covers a wide range of temperature and sample types. If you have any questions about our testing services, please contact us and we will answer as quick as possible.

Q: How much do thermal expansion testing cost?
If you only need a limited number of thermal expansion tests, then our contract thermal expansion testing services are what you need. Request a quote today or contact us if you have any questions. We have a full-service thermal testing laboratory to accommodate your thermal expansion testing needs using the best thermal expansion measuring methods available.
