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.

Product Features
1. The chamber is constructed entirely of stainless steel,
resisting corrosion and significantly extending the product's
lifespan.
2. Two tempered glass doors, front and side, facilitate observation
during testing.
3. Standard and wide stainless steel specimen clamps are available.
4. The ignition source can be positioned vertically or at a
45-degree angle, suitable for bottom and edge ignition.
5. The flame height is adjusted using a precision needle valve.
6. A flame height measurement device and a specimen distance gauge
are provided.
7. The specimen holder can be mechanically moved up and down, as
well as left and right.
