ASTM E1354-16a Standard cone calorimeter test: Cone calorimeter test has an advantage over Bunsen burner type tests because the heat release rate can be related to real world vehicle fire scenarios. Previous research has demonstrated repeatability. WebApr 6, 2024 · Additionally, ASTM E84 does not provide a rating system like UL 94, making it less suitable for evaluating the safety of a product in high-risk environments. UL 94 Flame Size. The UL 94 test is designed to evaluate the flammability of materials using a specific flame size, which is determined based on the thickness of the material being tested.
