This test method provides stakeholders (runway deicing/anti-icing product manufacturers, users, regulators, and airport authorities) with a relative ice penetration capacity of runway deicing/anti-icing product, by measuring the ice penetration as a function of time. Such runway deicing/anti-icing products are often also used on taxiways and other paved areas. This test method does not quantitatively measure the theoretical or extended time of ice penetration capability of ready-to-use runway deicing/anti-icing product in liquid or solid form.
