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 |
