Boeing Testing for Smoke Emission & Toxic Gas Generation

Adhering to Boeing tests BSS 7238 Rev C and BSS 7239 Rev A provides a dual assurance: low smoke generation and low toxicity under fire exposure. Together, these standards form a rigorous benchmark for qualifying adhesives, composites, coatings, and other materials for use in Boeing aircraft interiors and systems, especially where fire safety and occupant protection are paramount.

Boeing’s BSS 7238, Revision C is a standard test method focused on smoke density from materials used in aircraft interiors and structural assemblies. Under this protocol, specimens are exposed to combustion (both flaming and non-flaming modes) in a closed chamber. The test aims to ensure that materials generate acceptably low smoke loads.

Complementing BSS 7238 is BSS 7239, Revision A, which addresses toxic gas generation during material combustion. This test quantifies concentrations of potentially harmful gases produced. The goal is to verify that a material’s combustion products remain within acceptable parts-per-million (ppm) bounds of toxicity, safeguarding occupants from hazardous inhalation during fire events.

Master Bond EP90FR-V passes these Boeing tests.
