1.1 Purpose
The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide the sample selection and endurance
time test procedures, for SAE Type II, III, and IV aircraft deicing/anti-icing fluids, required for the generation of endurance
time data of acceptable quality for review by the SAE G-12 Holdover Time Subcommittee.
1.2 Examination of Endurance Time Data
Periodically, the SAE G-12 Holdover Time Subcommittee examines endurance time test data of SAE Type II, III, and IV
aircraft deicing/anti-icing fluids and validates, based on the endurance time data, if such fluids can be used in conjunction
with SAE Type II, III, or IV fluid holdover time guidelines. As the SAE G-12 Holdover Time Subcommittee examines
endurance time data, it will take into consideration the effects of natural variability of precipitation both in time and space
to generate or adjust holdover time guidelines.
1.3 Limits
This ARP provides laboratory simulation of freezing fog, freezing drizzle, light freezing rain, snow and rain on cold soaked
wing. Other forms of freezing/frozen precipitation are not addressed in this ARP.
1.4 Testing Agent(s)
1.4.1 Independence of the Testing Agents
A testing agent shall be independent of the fluid manufacturer and fluid vendor.
1.4.2 Role of the Testing Agent
The testing agent shall coordinate activities related to the sample selection procedures (see Section 3).
1.4.3 Sending Samples
Fluid samples for testing shall be sent to a testing agent for verification under the sample selection procedures. In turn
the testing agent, if the requirements of the applicable sample selection procedure are fulfilled, shall send the samples to
the facility/site for endurance time testing.
1.5 Test Facility/Site
1.5.1 Independence of the Test Facility/Site
The test facility/site shall be independent of the fluid manufacturer and fluid vendor.
1.5.2 Role of the Test Facility/Site
The test facility/site shall be responsible for performing the endurance time tests (see Sections 4 to 11).
1.6 Units
The values stated in SI units are to be regarded as the standard.
1.7 Safety
While the materials, methods, applications, and processes described or referenced in this ARP may involve the use of
hazardous materials, this ARP does not address the hazards that may be involved in such use. It is the sole
responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and processes and
to take necessary precautionary measures to ensure the health and safety of all personnel involved.strRefField
