This research project will review two approved special permits (DOT-SP14940 and DOT-SP20638) to evaluate if the current Wall Abuse Test or alternative ASTM tests (D5628-10 and D1709-98) better determine safety equivalence for aerosol containers with reduced wall thickness. The project aims to understand which test procedure most accurately represents real-world conditions, potentially easing cost and material burdens on the aerosol industry. No specific timelines or budget amounts are mentioned in the description. The location for performance of services is not specified. The findings could serve as a foundation for future rulemaking and establish uniform safety standards across the industry.
