本文件规定了环境试验箱的最低要求，以及根据飞机除冰/防冰液的现行材料规范进行防冰性能试验的试验程序。该试验方法的主要目的是在受控实验室条件下测定AMS1424 I型和AMS1428 II、III和IV型液体的防冰耐久性。

This document establishes the minimum requirements for an environmental test chamber, and test procedures to carry out anti-icing performance tests according to the current materials specification for aircraft deicing/anti-icing fluids. The primary purpose for such a test method is to determine the anti icing endurance under controlled laboratory conditions of AMS1424 Type I and AMS1428 Type II, III, and IV fluids.
