This SAE Standard covers the minimum requirements for design, construction, and testing of devices to prevent the propagation of backfire flame from within the gasoline engine to the surrounding atmosphere.
The committee discussed the potential for failures of some arrestors on high volume intake assemblies. Those with higher volume than the 75 cubic inch test fixture can develop higher pressures, and arrestors that pass the fixture test have been shown to fail when tested on the actual induction assembly. Committee modified the requirements in 18.104.22.168.1 to require testing on a representative induction assembly when its volume is greater than 75 cubic inches. The committee also reworded the definition of induction system was needed for what constitutes induction assembly
