MKEM
MKEM is a SFS 5636 (Finland) cable designation: M = M: plastic insulation ('M = Muovi, muovieristetty'); PVC on the maker sheets; K = K: stranded conductor ('kerrattu johdin (MKEM)'); E = E: fine-wire conductor ('hienolankainen kaapelin johdin (MKEM)'); MKEM = MKEM: PVC-insulated single-core wire with a flexible fine-wire copper conductor, 450/750 V (H07V-K class); MKEM-HF halogen free. 450/750 V, 70 C conductor, 160 C short circuit (MKEM-HF sheet). EN 50525-3-31 (MKEM-HF, Prysmian); Draka MKEM 90 450/750 V.

What is MKEM cable?
MKEM: PVC-insulated single-core wire with a flexible fine-wire copper conductor, 450/750 V (H07V-K class); MKEM-HF halogen free. Rating: 450/750 V, 70 C conductor, 160 C short circuit (MKEM-HF sheet). Standard: EN 50525-3-31 (MKEM-HF, Prysmian); Draka MKEM 90 450/750 V.
Taloon listing 'Asennusjohto Draka MKEM 90 1,5 SI': 'Muovieristeinen johdin, taipuisa kuparijohdin, MKEM 90 750 V, LINYL ... Taipuisa hienolankainen kuparijohdin, Linyl PVC-muovi-eristys', for fixed installation in conduit and internal wiring (retail, secondary). Prysmian 'MKEM-HF C-PRo 450/750 V Eristetty halogeeniton hienolankainen johdin', EN 50525-3-31, copper, halogen-free plastic insulation (manufacturer). fi.wikipedia uses MKEM as its example for E and K; the last M is not split out there and is not read letter by letter here. The colour word after the size (SI blue, MU black, RU brown, KEVI green-yellow) is the core colour. Letters from fi.wikipedia 'Kaapeleiden merkintätavat' (secondary; it cites Sähköinfo's handbook and SFS 600): A = aluminium as the first letter, C = concentric copper neutral or protective conductor, E = fine-wire conductor (MKEM), K = cable, or stranded conductor (MKEM), M = plastic (muovi), O = control cable (MMO), S = indoor cable (MHS), X = cross-linked polyethylene; an S after the size is a green-yellow core, N none.

Fire behaviour (EU CPR)
Halogen-free compound (MKEM). 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):
