The Society of Automotive Engineers (SAE) standards are used primarily by designers, manufacturers, and maintenance personnel in the automotive and aerospace industries. These standards are also a useful and effective series for the metals, plastics, rubber, chemical and fastener industries in their standardization efforts. Automotive SAE standards begin with the upper case letters SAE. Immediately after this prefix the letter J appears, and it is followed by a numerical code. Prefixes for other standards vary, such as AS, AIR, and ARP with a numerical code. Additional phone number for outside US and Canada is 724 766 4970. Example: SAE J441; SAE J775
