ASTM E228 – Linear Thermal Expansion of Solid Materials with a Push-Rod Dilatometer

To request a quotation for any test email for a prompt reply


ASTM E228 testing covers the determination of the linear thermal expansion of rigid solid materials using push-rod dilatometers. Touchstone has the capability of going from -150?C to 500?C (-238?F to 932?F).

Thermal expansion is the property of matter to change in volume in response to a change in temperature. The coefficient of thermal expansion (CTE) describes how the size of an object changes with a change in temperature. During testing, a push-rod tube dilatometer will determine the change in length of the specimen relative to the change in temperature specified by the customer. The linear thermal expansion and the coefficients of linear thermal expansion are calculated from the recorded data.
