ASTM E228 Linear Thermal Expansion of Solid Materials with a Push-Rod Dilatometer
ASTM E228 is a standard test method used to measure the linear thermal expansion of solid materials. This test method is employed in industries such as aerospace, automotive, construction, and manufacturing to assess how materials expand or contract under different temperature conditions.
GET STARTED
Introduction to ASTM E228
ASTM E228 uses a push-rod dilatometer to provide a standardized method for calculating the linear thermal expansion of solid materials. When a material is exposed to temperature changes, linear thermal expansion describes the change in dimension that occurs. When choosing and designing materials for applications where dimensional stability is essential, this test method makes it possible to determine thermal expansion coefficients precisely.
ASTM E228 test method is useful for qualitative characterization, research, development, and specification purposes.
ASTM E228 Test Method
The ASTM E228 test method involves subjecting a specimen to controlled temperature changes while measuring its dimensional changes. The test is conducted in the following steps:
Specimen Preparation
The specimen is prepared according to the specified requirements and is ensured to be clean and free from any contaminants.
Test Setup and Execution
The sample is inserted into the push-rod dilatometer device and heated or cooled according to a known and controlled temperature. The push-rod dilatometer is utilized to gauge changes in the specimen’s dimensions. The temperature-dependent changes in dimension are noted.
ASTM E228 Specimens
Specimen details
ASTM E228 Specimens are solid materials, including metals, ceramics, polymers, and composites.
Specimen dimensions
The general sample size for ASTM E228 varies depending on the material and its intended application.
Specimen preparation
The specimen is prepared according to the specified requirements, such as machining, polishing, and cleaning, to minimize any potential surface effects on the measurements.
ASTM E228 Results
The test method ASTM E228 evaluates the material’s linear thermal expansion coefficient. By dividing the specimen’s new length or dimension by its original length or dimension, then adding the temperature change, we can determine the linear thermal expansion coefficient. This coefficient aids in understanding the material’s dimensional stability under various thermal circumstances by representing the material’s sensitivity to temperature changes.
Tests Related to ASTM E228 ASTM E228 is connected to various test procedures used to assess the thermal properties of materials, including ASTM D696 for the linear thermal expansion of composites and plastics and ASTM E831 for the linear thermal expansion of rigid solids.
