Applications
Heat deflection temperature serves as a key parameter for characterizing the thermomechanical deformation behavior of materials under actual applied loads, and constitutes a critical indicator for assessing the structural stability and dimensional integrity of materials in high-temperature service environments.
Test Method
The test procedure for heat deflection temperature typically involves placing the test specimen on a support with a specified span, applying a predefined load to the specimen, and then placing the entire assembly in a temperature-controlled environment with a gradual heating rate. When the deformation of the specimen reaches the pre-specified limit value, the temperature recorded at that exact moment is defined as the heat deflection temperature of the material.
