The EU Construction Products Regulation (CPR) establishes unified fire safety requirements for all construction cables placed on the European market. Officially implemented on 1 July 2017 under EU Regulation 2016/364 and the harmonized standard EN 50575, the regulation defines a seven-level fire reaction classification system (Aca to Fca) together with supplementary grading for smoke emission, flaming droplets, and acidity. It applies to power cables, control and communication cables, and optical fibre cables used in building installations. This article systematically introduces the full set of CPR-compliant test standards, including EN ISO 1716, EN 60332-1-2, EN 50399, EN 61034-2, and EN 60754-2, and explains the corresponding test procedures, performance indicators, and AVCP conformity verification systems. It also clarifies the regional differences in minimum CPR enforcement requirements among EU member states. This overview aims to help cable manufacturers, suppliers, and exporters fully understand EU cable CPR compliance rules, standard specifications, and market access criteria for safe and standardized product distribution across European construction projects.
