This test method provides stakeholders (runway deicing chemical manufacturers, users, regulators, and airport authorities) with a relative ice penetration capacity of runway deicing/anti-icing chemicals, by measuring the ice penetration as a function of time. Such runway deicing/anti-icing 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 penetration 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. The ice penetration test method has been modified in order to add a second test temperature: -2 °C. The test method involves the use of a new test support (3.3.2) and new ice preparation procedure (3.3.4). The new ice penetration test method is described in 3.4.5.
