PC Control Model ISO 5657 Building Materials Ignitability Flammability Tester
SL-FL88 Building Material Ignition Performance Tester
1. Machine Introduction
This flammability tester is designed for evaluating the ignition performance of building materials with thickness not exceeding 70mm when placed horizontally under specified thermal radiation conditions. It effectively assesses wall and ceiling lining materials, flooring systems, exterior cladding, and thermal insulation materials for air ducts.
The tester accurately simulates specific fire scenarios, providing results that reflect real-world combustion performance. It clearly distinguishes between easily ignitable materials and fire-resistant materials, helping to evaluate material fire risks.
