YYF008 Surface Flame Spread Test Apparatus Building Material Flame Spread Tester

YYF008 Surface Flame Spread Test Apparatus
Building Material Flame Spread Tester for comprehensive fire safety testing and classification of construction materials.
Product Overview
The YYF008 Surface Flame Spread Test Apparatus is designed for British building materials and high iron flame retardant testing standards. This precision instrument determines the classification of surface flame spread for construction products in compliance with BS 476-7 standards.
Testing Methodology
This apparatus evaluates flame extension on exposed surfaces of walls and ceilings through controlled radiation heat changes. The test method utilizes small flames to ignite samples and determines critical heat flux levels for accurate fire risk assessment.
Standards Compliance
Conforms to BS 476 Part 7: Method for classification of the surface spread of flame of products
Technical Features
  • Stainless steel frame construction for durability and corrosion resistance
  • Integrated ignition system with electronic ignition, automatic flameout, and safety monitoring
  • Removable stainless steel exhaust pipe with easy-to-clean thermocouple
  • Precision burner tube: 3.0mm internal diameter, 6.4mm outer diameter
  • Flame positioning: 28±2mm above sample, 6mm above exposed surface bottom
  • Flame height adjustment: 75mm to 100mm range
  • Sample size compatibility: 885mm x 270mm
  • Radiant panel installation at 1250mm ground height
  • BS476-7 standard sample device with 90-degree radiation plate
  • Advanced radiation device: 850mm x 850mm porous refractory blocks
  • Water-cooled sample fixture with temperature control (max 35°C outlet)
  • Cooling water flow rate: 12L/min
  • Gas flow rate: 1500±200ml/min
  • Adjustable sample positioning for flexible test configurations
  • Automatic power output control based on test duration
  • Computerized data processing and test report generation
Application & Classification
The test method involves igniting samples in the combustion chamber using gas-fired radiant panels and medium-sized gas burners. Radiation intensity is maintained at 32.5kw/m² at 75mm distance. Samples are exposed to radiant heat for 10 minutes, with flame propagation levels recorded at 1.5 and 10-minute intervals. Results are classified into four grades, with Grade 4 materials representing high fire risk and unsuitable for building applications.
