(see and 3): t = 0, 04 D + 0,8 mm with a minimum thickness of , mm where D is the fictitious diameter under the sheath d) for unarmoured double-sheathed cables (see 5.1 2): t = 0, 025 D + 0,9 mm, with a m inim um thickness of , mm e) for armoured double-sheathed cables (see 4): t = 0, 025 D + 0, mm , with a m inim um thickness of 0, m m The thickness at an y point shall satisfy the prescriptions given in of I EC 60092350: 201 5.9.4 Colour of outer sheath The outer sheath shall be coloured black or grey, or, for fire resistant cables orange, unless otherwise specified by the purchaser at the
