Flammability rating of internal wiring
9.2.1 a)
61010-1(ed.2)
Standard(s)- (year and edition):
IEC 61010-1, ed. 2, 2001
Sub clause(s):
9.2.1 a)
Sheet n°: DSH 618
Subject:
Flammability rating of internal wiring
Key words:
Wires, flammability,
Decision approved by the CTL Plenary meeting 2007
Question:
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.
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)
Decision:
Wires rated e.g. VW-1 or FT-1 or according to IEC 60332-1-2 are deemed equivalent and can be accepted.
