A TSO (Technical Standard Order) is a minimum performance standard for specified materials, parts, and appliances used on civil aircraft. When a manufacturer is authorized to produce a material, part, or appliance to a TSO standard, it is referred to as TSO authorization. For TSO parts like TSO-C123A, TSO-C148, TSO-C113, TSO-C50C, TSO-C39C, Purchasing Union is here to help. Owned and operated by ASAP Semiconductor, we have access to an inventory of more than two billion new and obsolete parts for the aerospace, civil aviation, and defense industries, all available with short lead times and competitive prices.
