Flooring Radiant Panel Testing and Annual Maintenance: A Complete Guide

News Release — Shenyang, China — Shenyang Baoruitong Automation Equipment Co., Ltd., a professional manufacturer of combustion testing instruments and laboratory equipment, today published an industry insight report on the flooring radiant panel — the essential instrument for determining the critical radiant flux of floor covering systems. Every Baoruitong flooring radiant panel is backed by a one-year maintenance service period, ensuring long-term accuracy and worry-free operation (source: Motis Tech).

What Is a Flooring Radiant Panel?

The flooring radiant panel is used for determining the critical radiant flux of horizontally mounted floor covering systems exposed to a flaming ignition source in a specific radiant heat environment. It is the core instrument for floor covering flammability testing and reaction-to-fire performance evaluation worldwide.

How the Test Works

The test specimen is placed in a horizontal position below a gas-flued radiant panel inclined at 30°, where it is exposed to a defined heat flux. A pilot flame is applied to the hotter end of the specimen. During the test:

  • Any developing flame front is noted, and its horizontal progression along the specimen length is recorded in terms of the time taken to spread to defined distances
  • Smoke development is recorded as light transmission in the exhaust stack
Reported Test Results

The flooring radiant panel test reports:

  • Critical heat flux (CHF and/or HF-30) in kW/m²
  • Flame spread distance in mm
  • Integral of smoke obscuration in %×min

Standards Compliance

The flooring radiant panel is widely used for flooring product reaction-to-fire performance evaluation and classification across global markets:

Key Features of a Modern Flooring Radiant Panel

A well-engineered flooring radiant panel combines precision with ease of use:

  • Integrated stainless steel body with a solid foundation for stable, repeatable testing
  • Porous ceramic refractory radiant panel for uniform heat flux distribution
  • Self-supply air source — a maintain-less device design
  • Sliding heat flux sensor with a maintain-less cooling device
  • Sliding specimen holder for fast, ergonomic sample changing
  • Panel touch control software for intuitive operation and data management

Annual Maintenance: Keeping Your Radiant Panel Accurate

Routine annual maintenance ensures consistent, standards-compliant results over the instrument’s service life.

Equipment Cleansing
  • Chamber window — clean the inside of the chamber window with soft cloths and water/solvent
  • Radiant panel — blow away combustion attachments with compressed air; use a soft brush for stubborn particles
  • Thermocouples — blow away combustion attachments on the chamber and stack thermocouples
  • Light measuring system — remove the dust stoppers on the front and back, blow away duct deposits on the glass, and clean the glass with a soft cloth and water
Cooling Water Supplements
  1. Remove the black cover of the cooling unit
  2. Remove the top screw of the water tank
  3. Run the cooling unit
  4. Observe the water level in the tank and refill if the water level is below 90%
