AC184 was published by the International Code Council Evaluation Service (ICC-ES) to provide a clear, scientifically based definition of "positive attachment" for recessed lighting fixtures in suspended ceiling systems.
The criteria outlines both static and dynamic testing requirements that attachment devices must pass to be deemed acceptable for use in meeting building code requirements for positive attachment.
The SFC by AGI Seismic Products is the first device to achieve compliance with AC184, demonstrating that the fixture and ceiling grid behave as a single unified module under simulated earthquake conditions.
