Scope:

This document describes:

a. the preparatory steps to test experimental Type II, III, and IV fluids according to AMS1428;

b. the recommendations for the preparation of samples for endurance time testing according to ARP5485;

c. a short description of wind tunnel testing;

d. a short description of the recommended field spray test;

e. the protocol to generate draft holdover time guidelines from endurance time data obtained from ARP5485;

f. the protocol for inclusion of Type II, III, and IV fluids on the FAA and Transport Canada lists of fluids and the protocol for updating the lists of fluids;

g. the role of the SAE G-12 Aircraft Deicing Fluids Committee;

h. the role of the SAE G-12 Holdover Time Committee; and

i. the process for the publication of Type II, III, and IV holdover time guidelines.

This document does not describe laboratory testing procedures.

This document does not include the qualification requirements for AMS1424 Type I fluids (these are provided in ARP6207).

Rationale:

This document has been updated to reflect current practices for obtaining holdover times for SAE Type II, III, and IV fluids. This includes the addition of a protocol to obtain lowest and highest usable precipitation rates from snow endurance time data sets, the addition of a description of wind tunnel testing, and the removal of the statement that Type IV fluids are included in the analysis to determine Type II generic holdover times. The title of the document has been modified to harmonize it with the new sister standard being published for SAE Type I Fluids. Editorial changes have been made to reflect the current format of the holdover time guidelines and to improve clarity.
