ISO 11925 Single Flame Source Tester with Vertical or 45-degree Ignition and

Product Specification

ISO 11925 Single Flame Source Tester 

Product information

The ISO 11925 Flammability Tester is a specialized instrument designed to evaluate the ignitability of building materials under direct exposure to a small flame, adhering to international standards such as ISO 11925-2:2020 (Single-flame source test) . This tester is essential for assessing a wide range of construction and decorative products, including wall and ceiling panels, flooring (e.g., carpets, vinyl, and wood laminates), insulation materials (e.g., polystyrene foam, mineral wool), roofing membranes, composite boards, textiles, and cable sheaths. By simulating real-world fire scenarios, Single-Flame Source Test is widely used to assess the flammability performance class of construction or railway material, such as EN 13501-1, EN 45545-2, DIN 4102, DIN 5510-2, etc., making it a critical tool for manufacturers and testing labs focused on fire safety in building materials.
