Add the following after NOTE 2: In respect of cables and their Reaction to Fire, these protective measures are now expressed by reference to the Construction Products Regulation (CPR), and the relevant Euroclasses according to EN 13501-6. NOTE Z1 Whilst the CPR requires the manufacturer to declare the reaction to fire performance of the cable in accordance with procedures and classifications that are common across the EU, it is the responsibility of the Member State to determine which classification is required for any particular application or installation. National statutory requirements may therefore override the levels quoted here.
