Cone Calorimeter Test and Smoke Chamber Test

Test Conditions

  • Size of the samples: 100x100 up to 4mm thick 3 measures per sample
  • Multiple heat flux levels:
    • 25 kW/m²
    • 50 kW/m²
    • 65 kW/m²

Important Parameters Measured And Calculated

  • Heat Release Rate (HRR): Rate at which heat is generated by fire.
  • Peak of Heat Release Rate (pHRR ): Maximum of HRR.
  • Total Heat Release (THR): Sum of the heat released from the ignition.
  • ARHE: Average Rate of Heat Emission.
  • MARHE: Maximum of ARHE.

ADINS® Clay 80T - Cone Calorimeter Test - 1

Test Conditions

  • Radiation applied = 50 kW/m 2 .
  • Distance between sample surface and radiation source = 25 mm.
  • Size of the samples: 75x75mm, 2 3 mm thickness. 3 measures per sample
  • Optional pilot flame

Important Parameters Measured And Calculated

  • Specific Optical Density (Dₛ): Density of smoke measured by an opacimeter.
  • Maximum Dₛ (Dₛ) max
  • VOF4: Integral of the DS(t) curve calculated from t=0 to t=4min.
  • Total Smoke Production (TSP): sum of the smoke released from the ignition.

Test Conclusions
  • In the UL 94 test we can see how the samples not drip
  • All samples showed similar behaviour in the cone calorimeter test
  • When ADINS is added into the PP/ intumescent formulations the Total Smoke Production and the Smoke Density is reduced in all cases
