The JCKR Building Material Combustibility Test Apparatus is a high-precision, professional single-flame fire testing instrument developed strictly in accordance with ISO 11925-2:2026, EN 13501-1 (Euroclass B/C/D/E), GB/T 8626, DIN 4102-1 (B2), and EN 13238 standards. It is engineered to perform vertical single-flame impingement tests on flat construction and decorative material samples without external thermal radiation, assessing direct ignitability and flame spread behavior.
Essential for classifying building materials into fire resistance grades B1 (flame retardant) and B2 (combustible) as required by GB 8624, as well as European Euroclass grades, this versatile Single Flame Ignitability Tester features a 1.5mm heavy-duty stainless steel cabinet, a 7-inch industrial color touchscreen, full motorized mechanical adjustment (for burner 45° tilting and specimen positioning), high-voltage auto-ignition, and a complete suite of standard mounting accessories for certified quality inspection and product R&D.

Technological Features of JCKR Single Flame Ignitability Tester
- Full Stainless Steel Enclosure with Double Tempered Glass Windows: Constructed with a 1.5mm thick corrosion-resistant stainless steel cabinet designed for rigorous daily laboratory use. Dual heat-resistant tempered glass doors provide multi-angle visual tracking without compromising chamber airflow or operator safety.
- Full Electric Motorized Positioning & Automated 45° Burner Tilt: Features motor-driven vertical sample lifting and electric 45° tilting/reset for the burner assembly. The burner adjusts forward, backward, left, and right to perfectly match diverse specimen thicknesses, including melting or multi-layer materials.
- 7-Inch Industrial Touchscreen Controller with Built-in 4G Storage: Driven by an industrial color touch panel (800×480 resolution) with 512M RAM and 4GB built-in storage. Offers one-touch parameter setups, configurable flame exposure timers (5s / 15s / 30s), automatic curve logging, and USB data export.
- High-Voltage Auto-Ignition & Retractable Flame System: Equipped with a high-voltage electronic ignition system with auto-reset capabilities. The burner automatically advances to the specimen for the programmed duration (e.g., 15s or 30s) and retracts upon test completion to ensure repeatable flame application.
- All-Inclusive Standard Accessory Kit Included: Supplied with 3 specialized specimen holder types (for standard, melting/shrinking, and thick multi-layer samples >10mm), a 90° rotating hanging bracket, specimen preparation molds, dual burner gauges, and an adjustable exhaust fan with an air velocity sensor.

System Architecture & Testing Workflow of Single Flame Ignitability Tester
Standardized Testing Workflow:
- Mount the flat specimen (or multi-layer board) into the appropriate stainless steel specimen frame.
- Position the burner and set the flame height to 20mm using the included flame calibration gauge.
- Select the surface or edge impingement mode and preset the flame application time (e.g., 15s or 30s) on the 7-inch touchscreen.
- Initiate the auto-ignition sequence; the burner automatically tilts to 45°, advances to the specimen, applies the flame, and retracts precisely when the timer expires.
- Observe whether the flame tip reaches the 150mm mark on the sample within the specified time, then log the archived test report on the PC or USB drive.
Target Customer Applications:
- Flat wall panel, insulation board, flooring, and decorative composite product factories.
- Third-party fire safety testing laboratories and international material certification bodies.
- Construction engineering inspection bureaus and architectural quality supervision departments.
- University material engineering departments and fire safety science research centers.
Building Material Combustibility Test Apparatus FAQ
Q1: What is the difference between Surface Impingement and Edge Impingement in ISO 11925-2?
A: Surface impingement applies the 45° flame directly onto the flat face of the specimen (typically 40mm above the bottom edge). Edge impingement applies the flame directly to the center of the bottom edge of the sample. The JCKR tester easily toggles between both modes using motorized adjustments.
Q2: What role does ISO 11925-2 play in the European Euroclass fire classification system?
A: ISO 11925-2 is a mandatory reaction-to-fire test required for Euroclass B, C, D, and E classifications under EN 13501-1. Passing this single-flame test proves that a material resists small flame ignition without rapid flame spread.
Q3: Are additional mounting accessories required for testing thick or melting materials?
A: No. The JCKR apparatus comes complete with 3 standard sample holder configurations, including multi-layer frames for specimens over 10mm thick and specialized grid trays for materials that melt or shrink away from the flame.
