This paper describes the chemical and photographic analyses performed on 112 explosive transfer lines used to initiate aircraft emergency escape systems for a variety of military and NASA aircraft. The purpose was to provide quantitative chemical data on in-service explosive transfer lines as affected by both age and heat treatment. These data are necessary in order to make reliable, responsible, and conservative estimations of inservice cord life extension. The approach was to a develop a test methodology, b characterize the types of transfer lines in use in this country, c analyze these lines following a repeat of the thermal tests conducted in the original qualification, and d conduct a degradation investigation on the explosives currently in use. The results of this testing indicate that rigid explosive transfer lines are not adversely affected by age, service, or a repeat of the thermal qualification tests. Author
