Single Flame Source Test Ignitability Tester EN ISO 11925-2/DIN 53438

The building materials flammability test furnace is in the normal combustion environment, with a small flame directly impacted the vertical specimen to determine the combustibility of the building products. The flammability test furnace for building materials is based on the principle of Kleinbrenner (Klein Brenner), which is directly impacted by a vertical flame. It is used to determine the combustion performance of B grade building materials (namely, the judgement of burning performance and flame retardant grade B of building materials).

EN ISO 11925-2

• The operation in line with ergonomic design, test all through the touch screen operation, high degree of automation. Otherwise, the previous test results can be stored and can access the previous test data.
• Controllable automatic lifting of servo motor drive pattern frame.
• The Bunsen Burner can be advanced and retreat and adjusted.
• 1.5mm stainless steel plate box
• Double angle observation test of 2 heat-resistant tempered glass doors, double (with lock) is convenient and practical.
• High pressure automatic ignition and durable combustion.
• The point fire source can be automatically tilted by 45 degrees.
• The height of the flame is adjusted by the precision regulating valve.

Frequently Asked Questions

Q1: What standards does the SL-FL12 comply with?

A1: The SL‑FL12 complies with EN ISO 11925‑2 and DIN 53438. Test results are applicable to fire classifications under EN 13501‑1 (A2–E ratings) and IEC 61730‑2:2016 for PV modules.

Q2: What parameters does it measure?

A2: It measures after‑flame time (seconds), flame spread height (mm), ignitability, surface/edge ignition performance, and cotton pad ignition from dripping particles. Mode switching and timing are fully automated.

Q3: How stable and accurate is the flame?

A3: The flame is stable at 20mm±2mm with fine‑adjustment valves for precise control. A built‑in height gauge ensures calibration accuracy.

Q4: What are the lab environment requirements?

A4: Ambient temperature: 15–25°C; relative humidity: ≤85%; airflow: ≤0.2 m/s (built‑in anemometer monitors this). Gas: >95% purity propane at 10–50 kPa.

Q5: Is the equipment easy to operate and maintain?

A5: Yes. The 7‑inch touchscreen supports both English and Chinese interfaces. Auto‑ignition and auto‑timing simplify operation. On‑site training and SOP documentation get you running in one day.

Q6: What after‑sales support is provided?

A6: 1‑year warranty with lifetime technical assistance. Calibration services, spare parts (igniters, seals, regulators), and testing method development support are all available.
