Pertains to flexible cables, insulated and sheathed with halogen-free crosslinked compound and having low emission of smoke and corrosive gases when exposed to fire.

EN50525-3-21 applies to flexible cables, insulated and sheathed with halogen-free crosslinked compound and having low emission of smoke and corrosive gases when exposed to fire.

NOTE1 Low emission of smoke is checked in accordance with EN61034-2. Low emission of corrosive gases is checked as part of the check for absence of halogens (see AnnexB of EN50525-1).

The cables are of rated voltage U₀/U 450/750V.

The cables are intended for the connection of equipment and machinery to the fixed supply.

The maximum conductor operating temperature for each of the cables in this standard is 90°C.

NOTE2 HD 516 contains extensive guidance on the safe use of cables in this standard.

This EN50525-3-21 should be read in conjunction with EN50525-1, which specifies general requirements.
