Abstract:

This project investigates gaps in the UN Dangerous Goods Tests and Criteria Test N.1, which applies for both metals and non-metals. Metal and metal alloy fires are different from non-metal fires in that they typically burn at higher temperatures and are difficult to extinguish. Like non-metals, fine metal powders with high surface area can ignite readily, burn rapidly, and are more likely to explode or cause a flash fire if dispersed in air. This research found a range of burning rates, different ignition behaviors under a torch flame, and high temperatures measured in burn tests. The report also proposed an improved screening method to distinguish flammable solids. The improved method includes a stronger ignition source and requires the finest fraction be isolated for testing before exclusion from Division 4.1. Further recommendations were made for the full burn test, including clarification of test procedure language and descriptions of hazards.
