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. Purpose The purpose of this document is to recommend a procedure for testing and establishing acceptable flame arresting characteristics of the devices. Relationship of SAE Standard to ISO Standard This document is similar to ISO 13592 but has some technical differences. Rationale The use of non-metallic materials in flame arrestors and induction systems is becoming more prevalent throughout the Marine Industry. Inclusion of a heat-aging test as proposed in this standard provides a means to insure these materials will meet the requirements of the Marine Environment. Throttle bodies have been added to the document as they are required by law to have the same flame arresting protection as carburetors and induction systems. The document's relationship to ISO 13592 has been added to the document. Tolerances were changed/added to update the document to realistic and current practices. The UL94 rating was added to provide a current flammability rating for non-metallic materials.
