TFR-CVV-I/CAMS
TFR-CVV-I/CAMS is a KS / KEPCO type names (Korea) cable designation: TFR- = TFR-: tray flame retardant, a high flame-retardant PVC sheath for cable trays; CVV = CVV: control cable with PVC insulation and a PVC sheath; I/CAMS = I/CAMS: aluminium-mylar tape shields on each pair (individual) and over all pairs (common); TFR-CVV-I/CAMS = TFR-CVV-I/CAMS: CVV-I/CAMS with a high flame-retardant PVC sheath. 0.6/1 kV (Taihan p.42). KS C IEC 60502-1.

How to read a NBN (Belgian national cable names, ...B types) cable code
Fire behaviour (EU CPR)
Flame retardant (TFR-, TFR-CVV-I/CAMS). The single-cable test behind class Eca is EN 60332-1-2 (the flame stops within 425 mm). Bunched cables are tested by IEC 60332-3-24 category C (1.5 l/m, 20 min, char at most 2.5 m), which is not a CPR class test; the CPR ladder test for B1ca to Dca is EN 50399.
PVC sheath (TFR-, CVV, TFR-CVV-I/CAMS).
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):
EcaN1XV-R, Ahlsell (seller)Cca-s3,d1,a3FG16OR16, Nexans (La Triveneta Cavi)EcaU1000 R2V, Nexans (La Triveneta Cavi)EcaN2XSY, Waskönig+Walter (10 kV datasheet)
Listed as sources, alphabetically by maker. No maker pays to appear here.
A CPR class is declared by the maker in its Declaration of Performance and printed on the sheath (EN 50575 cl 7). This decoder does not assign one. What the CPR classes mean →
