Minimum Requirements 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 SAE AMS1424 Type I and AMS1428 Type II@ III@ and IV fluids. Hazardous Materials This test may involve the use of hazardous materials@ operations@ and equipment. This Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Standard Units The values stated in SI units are to be regarded as the standard.
