Question:' I5 R$ d6 E1 {! D
Insulated wires shall be equivalent FV-1 or better. Wires are not generally tested and rated according to FV-1. It is not easy to establish equivalence between different test classifications/methods if you are not involved directly in such testing procedures.1 C4 I5 T2 f& N2 f# ]. z1 y
Wires typically are rated VW-1 or FT-1. It is unclear if these flammability ratings are equivalent and thus acceptable (Same problem exists with IEC 60601-1 ed. 3)$ f* v0 b% n t3 f0 z7 k4 r
Decision:
