Annotation of standard text IEC 61249-3-6-ed.1.0 :

IEC 61249-3-6:2026 specifies requirements for properties of polytetrafluoroethylene (PTFE) filled unreinforced laminated sheet of a thickness 0,02 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. This document is applicable to the design, manufacture, use of PTFE filled unreinforced laminated sheet of defined flammability (vertical burning test), copper-clad. Its flame resistance is defined in terms of the flammability requirements of 8.3. L’IEC 61249-3-6:2026 specifie les exigences relatives aux proprietes des feuilles stratifiees non renforcees en PTFE avec charges d’une epaisseur comprise entre 0,02 mm et 3,2 mm, d’inflammabilite definie (essai de combustion verticale), plaquees cuivre. Le present document s’applique a la conception, a la fabrication et a l’utilisation des feuilles stratifiees non renforcees en PTFE avec charges d’inflammabilite definie (essai de combustion verticale), plaquees cuivre. Sa resistance a la flamme est definie en fonction des exigences d’inflammabilite du 8.3.
