NOTE 1 Low emission of smoke is checked in acco

25、rdance with EN 61034-2. Low emission of corrosive gases is checked as part of the check for absence of halogens (see Annex B of EN 50525-1). The cables are of rated voltages U0/U up to and including 450/750 V. NOTE 2 Cables rated 450/750 V may be used at 600/1 000 V when this cable is used in fixed

26、installations with mechanical protection, within switchgear and control gear - see HD 516. The cables are intended for fixed wiring applications. The maximum conductor operating temperature for each of the cables in this standard is 90 C. NOTE 3 HD 516 contains extensive guidance on the safe use of

27、cables in this standard. This EN 50525-3-41 should be read in conjunction with EN 50525-1, which specifies general requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.
