Heat Resistance
Heat resistance is a measure of the thermal endurance of plastic materials. It describes the ability of a test specimen to retain its shape up to a specified temperature under a specified load or to deform only within specified limits at a specified test temperature.¹
The heat resistance can be determined according to various standardised test methods such as Vicat and the Heat distortion temperature.
At UL we offer the following heat resistance tests.
Heat resistance test methods | Standards |
---|---|
Vicat | ISO 306 ASTM D1525 |
Heat distortion temperature | ISO 75-2 ISO 75-3 ASTM D648 JIS K7207 |
