The Flame Spread Tester for Thermal and Acoustic Insulation Materials is designed to evaluate the flame propagation characteristics of insulation and acoustic materials. You can expose samples to a standard thermal radiation source and ignite them with a controlled flame to determine their critical heat flux. This instrument is FAA-approved and compliant with international standards, providing accurate and repeatable measurements for aerospace, civil aviation, and material development applications.
Application
You can apply this tester in the following scenarios:
Aerospace material testing: Evaluate flame propagation of thermal and acoustic insulation materials in aircraft interiors.
Civil aviation compliance: Test materials in accordance with FAA FAR Part 25 Appendix F Part VI.
Material development: Assess thermal and acoustic insulation performance during R&D.
Quality control: Monitor flame spread properties in production lines to ensure safety compliance.
Compatible test standards and protocols: FAR Part 25 Appendix F Part VI, Airbus AITM 2.0053. Boeing BSS 7365. MH/T 6042‑2006. and relevant national standards.
