AMS 3208 refers to an aerospace material specification that details the requirements for a specific type of polytetrafluoroethylene (PTFE) tubing. This specification outlines the chemical composition, physical properties, and performance characteristics the tubing must possess to be deemed acceptable for use in aerospace applications. For instance, it specifies the allowable levels of impurities, the tensile strength and elongation requirements, and the dimensional tolerances necessary for proper function.
Adherence to this specification ensures a high degree of reliability and safety when using PTFE tubing in demanding aerospace environments. It provides a common standard for manufacturers, suppliers, and end-users, promoting consistency and predictability in material performance. Historically, the development and adoption of such specifications have been crucial in advancing aerospace technology by providing confidence in the materials employed.
