Abstract : The focus of the Transparency Durability Test Criteria Program was to develop a durability test methodology for aircraft transparency systems which includes laboratory coupon durability testing and field service data acquisition. These areas were used to advance the development, measurement, and comparison of coupon testing to in-service aircraft transparency durability, where durability is defined as the continued ability of the transparency to meet specified performance requirements. Summaries of coupon tests and field service data acquisition and analysis are reported. New coupon tests introduce in this program include combined testing such as dust erosion and craze testing. A relationship between craze resistance and rain erosion exposure was also demonstrated. Identification of technology voids and other approaches to improve durability assessment are discussed. This report also provides a summary of the major accomplishments of the program, including the core durability task and additional tasks including alternate QUV cycles, durability of coatings, and improved bolt hole durability.
