MHS
MHS is a SFS 5636 (Finland) cable designation: MHS = MHS: indoor telecommunication cable ('S = sisäasennuskaapeli (MHS)'), twisted pairs under an overall screen (SFS 5739); MHS = MHS: indoor telecommunication cable, twisted pairs of 0,5 mm solid tinned copper, PE insulation, overall aluminium-polyester screen with a drain wire; MHS LSZH with a halogen-free sheath. 100 V maximum operating voltage (Nexans). SFS 5739 (Nexans sheet).

What is MHS cable?
MHS: indoor telecommunication cable, twisted pairs of 0,5 mm solid tinned copper, PE insulation, overall aluminium-polyester screen with a drain wire; MHS LSZH with a halogen-free sheath. Rating: 100 V maximum operating voltage (Nexans). Standard: SFS 5739 (Nexans sheet).
Nexans sheet 'MHS LSZH 10x2x0,5' (generated 12/1/22): 'Pair twisted, screened telecommunication cable with halogen free, flame retardant sheath. MHS-LSZH is designed according to Finnish Standard SFS 5739 and is intended for indoor installation'; tinned annealed copper 0.5 mm, PE insulation, 'Aluminium-Polyester tape + tinned copper drain wire', HFFR sheath, grey, 100 V. fi.wikipedia gives S = indoor cable with MHS as the example; its H ('hohtosuojattu', glow-protected) is a high-voltage letter and is not applied here. 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 (MHS). 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):
