Description
PDCL-01 Radiant Heat Flux Tester for Floor Coverings | GB/T 11785 Critical Radiant Flux Test Machine
1. Product Overview
The PDCL-01 Radiant Heat Flux Test Apparatus is a standardized laboratory testing machine designed strictly to GB/T 11785-2005, dedicated to evaluating the fire reaction performance of all floor covering materials and their supporting substrates.
Under controlled laboratory radiant heat source conditions, this equipment measures the critical radiant flux of floor products to judge their flame spread resistance. It fully simulates real fire heat radiation scenarios, accurately capturing the combustion characteristics of carpets, wooden floors, composite flooring, plastic mats and underlayment materials. Test results serve as official fire grading data for flooring manufacturers, third-party fire certification labs and building material inspection institutions.
