What is NHXMH cable?
NHXMH: halogen-free installation cable with improved behaviour in a fire, the type of DIN VDE 0250-214. Rating: U0/U 300/500 V (clause 4); laying after DIN VDE 0298-3 (clause 7). Standard: DIN VDE 0250-214:2002-04 (1 core 1,5 to 16 mm², 2 to 5 cores 1,5 to 35 mm², 7 cores 1,5 and 2,5 mm², 5.1; bare copper, solid class 1 to 10 mm², stranded class 2 from 16 mm², 5.2; mean overall diameter limits, Table 1, e.g. 3 x 1,5 mm²: 8,0 to 9,6 mm; tests, Table 2: 2 kV a.c. for 5 min, flame DIN EN 50266-2-4, corrosivity DIN EN 50267-2-2, smoke density DIN EN 50268-2).
NHXMH-J has a green-and-yellow core, NHXMH-O none (3.2). The letter reading below this row is the DIN VDE 0250 letter code; this row is the type as the standard defines it.

DIN VDE type names (Germany): how to read the cable type names
Fire behaviour (EU CPR)
Halogen-free compound (HX, MH, NHXMH). Under the CPR this shows in the additional classes: acidity a1 to a3 (EN 60754-2) and smoke s1 to s3 (EN 50399; s1a and s1b add the 3 m cube test EN 61034-2). The main class, Aca to Fca, depends on the whole construction.
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):
