Abstract
Overview
EN IEC 61249-3-6:2026 specifies requirements for polytetrafluoroethylene (PTFE) filled, unreinforced laminate sheets-both copper-clad and unclad-intended for use in printed circuit boards (PCBs) and other interconnecting structures. This standard sets out test methods and criteria for properties such as flammability (vertical burning test), electrical and non-electrical characteristics, and quality assurance. Developed under the governance of CLC and IEC Technical Committee 91 (Electronics Assembly Technology), this standard plays a critical role in ensuring high performance and safety of materials used in electronics manufacturing.
