This paper investigates the fire performance of building insulation materials with different formulations and colors using the TCC 918 Cone Calorimeter in accordance with the ISO 5660-1 standard. Key fire behavior parameters, including time to ignition (TOI), peak heat release rate (Peak HRR), maximum average rate of heat emission (MARHE), and total smoke production (TSP), were tested under identical laboratory conditions. The results indicate evident performance discrepancies: grey insulation offers superior ignition resistance and stable low heat release; red insulation presents excellent smoke suppression capability; white insulation exhibits the worst fire resistance with fast ignition and intense heat release. This study validates that material composition significantly impacts fire characteristics, delivering standardized test data to support insulation formulation optimization, building fire safety design, and reliable material selection for modern construction projects.

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.

This paper elaborates on the working principle of carbon black content testers based on gravimetric combustion. It distinguishes carbon black content testing from dispersion testing, analyzes common measurement errors, and lists key instrument performance indicators and applicable standards. It also introduces standardized test equipment from BRT for plastic, cable and geosynthetic labs.
