This test method provides stakeholders (runway deicing chemical manufacturers, users, regulators and airport authorities) with relative ice undercutting capacity of runway deicing chemicals, by measuring the area of ice undercut pattern as a function of time. Such runway deicing chemicals are often also used on taxiways and other paved areas.
This test method does not quantitatively measure the theoretical or extended time of ice undercutting capability of ready-to-use runway deicing/anti-icing chemicals in liquid or solid form.
Section 3.4.3 of this SAE Aerospace Information Report has been modified by the addition of KAC 25% w/w solution as a new reference control solution for solid runway deicing/anti-icing chemical. The document also brings some editorial changes.
