SAE J2579 Localized Fire Evaluation Key Findings from Specific Laboratory Fire Testing 1) About 40% of the fires investigated resulted in localized fire conditions before conventional PRDs on end bosses would have activated. 2) While vehicle fires often lasted 30-60 minutes, the period of llocalized li d fi fire ddegradation d ti on th the storage t containers t i llasted t d lless than 10 minutes. See figure on next page. 3) The average maximum temperature during the localized fire period was less than 570°C with peak temperatures reaching approximately 600°C in 2 cases and 880°C in one case. 4) The rise in peak temperature near the end of the localized fire period often signaled the transition to an engulfing fire condition. 14
