Laboratorio Prevenzione Incendi, at Prato, accredited by ACCREDIA to EN ISO/IEC 17025 (0086) for fire testing of materials and components across four regimes at once — construction, railway, naval and aeronautical — plus REI-rated fire barriers. It is notified body 0987, carrying out CE marking of construction products under the Construction Products Regulation 305/2011 and of marine equipment under the Marine Equipment Directive 2014/90/EU, and is an accredited product certification body (241B). The transport regimes are what set it apart from a purely building-focused furnace house: a material bound for a train interior is classified on different criteria from the same material in a wall.
