The ISO 11925-2 Single Flame Source Test Ignitability Apparatus is engineered based on German Kleinbrenner principles, utilizing standardized flames to conduct vertical direct combustion tests on building material samples. This precision instrument accurately evaluates combustion characteristics and provides comprehensive fire safety testing solutions for laboratories, manufacturers, and research institutions.

This testing apparatus fully complies with multiple international standards including:

• EN ISO 11925-2: Reaction to fire tests - Ignitability of products subjected to direct impingement of flame
• DIN 53438: Testing of combustible materials
• DIN 4102-1: Fire behaviour of building materials and elements

The system covers detection requirements for fire protection levels B, C, D, E and Bfl, Cfl, Dfl, Efl under EN 13501-1 standard.

1. Prepare and secure test sample on the test stand
2. Pre-treat sample to achieve standard-required humidity and temperature
3. Connect combustion head and data acquisition system
4. Initiate test and record all parameters during combustion
5. Analyze results to evaluate material combustion performance
6. Shutdown equipment and perform routine maintenance

• Regularly inspect power lines, data cables, and combustion head interfaces
• Maintain cleanliness of combustion head and data acquisition system
• Periodically calibrate equipment to ensure testing accuracy

• Ensure test samples meet standard requirements for humidity, temperature, and dimensions
• Never leave test site unattended or shut down equipment during testing
• Maintain fire source safety and keep testing area dry and clean
• Follow operation manual guidelines for proper testing procedures
