Alternatives to 1,1,1 Trichloroethane Prior to Adhesive Bonding and Non-Destructive Inspection (NDI)
Abstract
The utilization of chlorinated solvents, specifically Class I Ozone Depleting Compounds (ODCs), has been continually scrutinized by the U.S. Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA). This is a direct result of the United States entering into an agreement with several other nations throughout the world to limit the production of these materials (Montreal Protocol 1987). In fact, the EPA has placed very heavy restrictions on the production of 1,1,1 trichloroethane, one of the most commonly known and utilized chlorinated solvents, as of January 1996. This announcement prompted the Aviation and Troop Command (ATCOM) to fund a program designed to identify, test and evaluate commercially available cleaners to replace 1,1,1 trichloroethane during the processing of aviation components. ATCOM requested the Army Research Laboratory - Materials Directorate to develop and execute this test program. Two critical cleaning applications were identified based upon a thorough review of all cleaning processes utilized during part manufacture, and repair at Army depots: cleaning prior to non-destructive inspection (NDI) and cleaning prior to adhesive bonding. This report discusses the rational behind identifying alternative cleaners for these applications, the test and evaluation plan, and the results of the test program.
