Work gloves designed for high-heat exposure must be tested using the vertical flame test to measure both after-burn time and after-glow time for EN 407 certification. This test measures the ability of the material to extinguish itself after being ignited using 4 performance levels.

Thermal protection from contact heat is determined by measuring a temperature rise of 10° C (50° F) on the inside of the glove. This is achieved by placing sample material on pre-heated plates and recording the temperature rise at each level for at least 15 seconds. When the Contact Heat performance level reaches 3 or 4, the Burning Behavior test must be performed and achieve at least a level 3, otherwise the maximum performance rating for Contact Heat will be reported as level 2.
