Abstract:  
ABSTRACT The history of shot peening specifications is presented in a chronological format with prelude of situations existing in1940. The specifications cited are of US origin and in the public domain (i.e. no proprietary specifications such as GE or Boeing are cited). Some specifications relating to media have been excluded for brevity. INTRODUCTION Early application of shot peening in the 1930's and 1940's relied upon proprietary specifications, primarily from General Motors. Efforts to improve fatigue life of critical aircraft components for World War 2 resulted in creation of specifications by the US Army, Navy and Air Force and also Society of Automotive Engineers. The data is presented in chronological sequence to establish a time-line of events.
