What Is the EN ISO 9239-1 Flooring Radiant Panel Test Apparatus?
The EN ISO 9239-1 Flooring Radiant Panel Test Apparatus (Radiant Panel Testing Machine / Flooring Radiant Panel Tester) is a high-precision testing system engineered to evaluate the burning behavior of floor coverings, including their substrates, backing materials, and underlays. Constructed with a robust combustion chamber and a dedicated control cabinet made of high-quality CNC-machined stainless steel, the EN ISO 9239-1 delivers exceptional reliability, precise temperature regulation, and accurate critical radiant flux measurements for laboratory quality control and regulatory compliance.
What Is the EN ISO 9239-1 Critical Radiant Flux Test?
The EN ISO 9239-1 Critical Radiant Flux Test (also known as the Flooring Radiant Panel Test or Radiant Panel Test for Floorings) is a standardized fire testing method designed to evaluate the burning behavior and critical heat flux text of floor coverings when exposed to a calibrated radiant heat energy source under controlled laboratory conditions. This test determines how far a flame propagates across a flooring specimen, providing critical data for assessing fire safety performance and compliance under major international standards such as EN ISO 9239-1 (Reaction to fire tests for floorings — Determination of the burning behaviour using a radiant heat source), ASTM E648, NFPA 253, and ASTM E970.
Applicable Materials
The PDCL-01 Flooring Radiant Panel Test Apparatus is widely used to test and describe the burning characteristics of various flooring systems, including:
- Textile Floor Coverings: Carpets, rugs, and woven textile floor systems.
- Resilient and Hard Floor Coverings: Vinyl tiles, linoleum, rubber flooring, and laminated wood products.
- Underlays and Substrates: Various backing materials, adhesives, and composite flooring assemblies whose components directly affect fire performance.
Main Functions and Modules
- Dual-Unit System Architecture: Consists of an integrated combustion chamber and an independent control cabinet for safe and convenient operation.
- Precision Radiant Heat Source: Designed to project a controlled radiant heat flux profile across the test specimen.
- 304 Stainless Steel Burner: Manufactured in-house from high-grade 304 stainless steel to ensure stable pilot flame performance (height: 60–120 mm).
- Advanced Control & Measurement: Equipped with a 0–15 kW/m² heat flux meter, hot-bulb anemometer (accuracy ± 0.1 m/s), and high-precision timing and temperature control systems.
- Corrosion-Resistant Construction: Built using high-quality stainless steel and thickened electroplated A3 steel for long-term durability in demanding laboratory environments.

Important Notes
- Multi-Standard Adaptability: The apparatus supports multiple testing standards including EN ISO 9239-1, ASTM E648, ASTM E970 and NFPA 253. (Note: When performing ASTM E970, the specimen frame, layout method, and radiant flux calibration parameters must be adjusted in accordance with the standard’s requirements.)
- Laboratory Ventilation: Ensure that the testing room is equipped with a properly calibrated exhaust system maintaining an air velocity of > (2.5 ± 0.2) m/s to safely remove combustion gases.
- Gas Line Safety: Check gas supply connections regularly for leaks and ensure high-purity (≥ 95%) propane, methane, or LPG is used under safe operating pressures.
