NYIF
NYIF is a DIN VDE type names (Germany) cable designation: N = German national (VDE) type; Y = PVC core insulation (YI 1); IF = Stegleitung: flat webbed wire, the cores side by side in a common outer covering joined by a web; without a further letter the covering is rubber (NYIF); Y = Outer covering of PVC (YM 1), NYIFY; NYIF = NYIF / NYIFY: flat webbed installation wire (Stegleitung), PVC insulated solid copper cores side by side in an outer covering of rubber (NYIF) or PVC (NYIFY). U0/U 230/400 V (clause 3); for laying in and under plaster, DIN VDE 0298-3 (clause 6). DIN VDE 0250-201:1992-09 (2 and 3 cores 1,5 to 4 mm², 4 and 5 cores 1,5 and 2,5 mm², 4.1; bare solid copper class 1, 4.2; PVC insulation YI 1, 0,4 / 0,5 / 0,6 mm at 1,5 / 2,5 / 4 mm², 4.3 and Table 1 column 6; cores side by side, 4.5; outer covering vulcanised rubber (NYIF) or PVC YM 1 (NYIFY), 0,8 / 0,9 / 0,9 mm, Table 1 column 7, with a wedge-shaped groove at least 0,3 mm deep in the middle of the web on both sides, 4.6; core colours DIN VDE 0293, 4.4).

What is NYIF cable?
NYIF: NYIF / NYIFY: flat webbed installation wire (Stegleitung), PVC insulated solid copper cores side by side in an outer covering of rubber (NYIF) or PVC (NYIFY). Rating: U0/U 230/400 V (clause 3); for laying in and under plaster, DIN VDE 0298-3 (clause 6). Standard: DIN VDE 0250-201:1992-09 (2 and 3 cores 1,5 to 4 mm², 4 and 5 cores 1,5 and 2,5 mm², 4.1; bare solid copper class 1, 4.2; PVC insulation YI 1, 0,4 / 0,5 / 0,6 mm at 1,5 / 2,5 / 4 mm², 4.3 and Table 1 column 6; cores side by side, 4.5; outer covering vulcanised rubber (NYIF) or PVC YM 1 (NYIFY), 0,8 / 0,9 / 0,9 mm, Table 1 column 7, with a wedge-shaped groove at least 0,3 mm deep in the middle of the web on both sides, 4.6; core colours DIN VDE 0293, 4.4).
Table 1 (minimum width / maximum outer dimensions, mm): 2x1,5 10,5 / 4,4 x 12; 2x2,5 12 / 5,2 x 13,5; 2x4 14 / 6 x 15,5; 3x1,5 17,5 / 4,4 x 19; 3x2,5 19,5 / 5,2 x 21,5; 3x4 23 / 6 x 25; 4x1,5 24 / 4,4 x 26; 4x2,5 27 / 5,2 x 29,5; 5x1,5 31 / 4,4 x 33; 5x2,5 34,5 / 5,2 x 37. Two cores are -O only; three to five -O or -J. The 0,4 mm insulation may be at no point below 0,30 mm (4.3). NYIF's rubber covering need not be a DIN VDE 0207-21 compound (4.6 a). The decoder draws the cores round, not webbed.
