Is the Hildegun Oven Glove tested for protection against molten metal splashes or radiant heat?

No, the oven glove has not been tested for limited flame spread, convective heat, radiant heat, small splashes of molten metal, or large quantities of molten metal — these are marked with an "X" in the standards table indicating tests that were not conducted. The glove is only rated for contact heat at performance level 2. It should not be used in situations involving these hazards.
