Heat deflection testers are specialized instruments designed to assess the heat resistance of materials. They measure the temperature at which a sample deflects under a specified load, indicating its ability to maintain dimensional stability under heat stress.
The heat deflection temperature (HDT) is the temperature at which a material deforms under a specified load. It is a critical parameter for assessing the suitability of materials for high-temperature applications.
Heat deflection testing is essential for ensuring the reliability and performance of materials in various industries. It helps engineers and manufacturers select appropriate materials for specific applications and avoid potential failures due to heat-induced deformation.
