Annotation of standard text IEC 61249-2-53-ed.1.0 :

IEC 61249-2-53:2025 specifies requirements for properties of PTFE unfilled reinforced laminated sheet of a thickness 0,05 mm up to 10,0 mm of defined flammability (vertical burning test), copper-clad. This part of IEC 61249 is applicable to the design, manufacture, use of PTFE unfilled reinforced laminated sheet of defined flammability (vertical burning test), copper-clad. Its flame resistance is defined in terms of the flammability requirements of 8.4. LIEC 61249-2-53:2025 fournit les exigences relatives aux proprietes des feuilles stratifiees renforcees non chargees en PTFE dune epaisseur comprise entre 0,05 mm et 10,0 mm, dinflammabilite definie (essai de combustion verticale), plaquees cuivre. La presente partie de lIEC 61249 sapplique a la conception, a la fabrication et a lutilisation des feuilles stratifiees renforcees non chargees en PTFE dinflammabilite definie (essai de combustion verticale), plaquees cuivre. Sa resistance a la flamme est definie en fonction des exigences dinflammabilite de 8.4.
