This document details the technical requirements to be used in the evaluation of materials and processes developed for use in stripping organic finishes from fixed wing commercial aircraft. The requirements herein are intended to ensure that the materials and processes used are not detrimental to the commercial aircraft when used as specified. These requirements are not intended to judge performance of the stripping method.
This document establishes a test procedure for determining the propensity of aircraft turbine engine cleaning and maintenance materials for causing stress-corrosion cracking of titanium alloy parts. The evaluation is conducted on representative titanium alloys by determining the effect of contact with cleaning and maintenance materials on tendency of pre-stressed titanium alloys to crack when subsequently heated to elevated temperatures.
This specification covers two types of cleaner in the form of a ready-to-use liquid. Primarily for removing soils, contaminants, and residues from aircraft glass windows by manual application. The cleaners covered by this specification shall be of the following types as ordered: Type I - Regular; and Type II - Antifogging.
This specification covers a corrosion-removing compound in the form of a liquid concentrate. Primarily for removing pitting corrosion and heavy surface oxidation from exterior aluminum surfaces of aircraft. Compounds meeting the requirements of this specification may cause hydrogen embrittlement of high-strength steels and will remove cadmium plate.
