ISO 13918:2017 specifies the following: - requirements for studs and ceramic ferrules for arc stud welding; - dimensions, materials and mechanical properties. Amendments are issued when it is found that new material may need to be added to an existing standardization document. Ferrule materials determine the mechanical precision, optical alignment, thermal stability, and long-term reliability of fiber optic connectors. Kyocera's extrusion molding process creates ferrules with excellent coaxiality, and our precision machining ensures excellent concentricity with precise. CEN and CENELEC are business catalysts in Europe, removing trade barriers for European industry and consumers in order to foster the European economy in global trading, the welfare of European citizens and the environment.
