This transition is driven by a clear technical case \u2014 reduced smoke generation, elimination of toxic and corrosive halogen gas emissions, superior flame propagation resistance, and a higher 110 \u00b0C continuous thermal rating \u2014 reinforced by mandatory regulatory requirements under AS\/NZS 3013, AS\/NZS 1670.3, and the IEC 60332\/60754\/61034 test framework.
