From the SAE International website:
"The Society of Automotive Engineers has more than 84,000 members - engineers, business executives, educators, and students from more than 97 countries - who share information and exchange ideas for advancing the engineering of mobility systems. SAE is your one-stop resource for standards development, events, and technical information and expertise used in designing, building, maintaining, and operating self-propelled vehicles for use on land or sea, in air or space."
"SAE standards are split into three main categories: Ground Vehicle Standards (J-Reports); Aerospace Standards; and Aerospace Material Specifications (AMS). Access to this up-to-date information is a key component of efficient product design, testing and operation. Because standards are an agreement on form, fit and function, they enable industries, engineering disciplines, and entire countries to talk to each other in a common language."
