Aerosol Testing

The request for information seeks input on evaluating the safety and effectiveness of two special permits, DOT-SP14940 and DOT-SP20638, which govern the design and testing of DOT 2P and DOT 2Q aerosol containers. These permits currently require containers to withstand a 1-meter drop and body wall abuse testing without leakage, based on a proprietary testing apparatus that ensures a minimum impact energy intensity of 70 kilojoules per square meter. The project aims to assess whether these methods accurately reflect real-world conditions or if standardized ASTM tests D5628-10 and D1709-98 offer a more reliable, scientifically validated approach to measuring container integrity, particularly for designs with reduced wall thickness. The ultimate goal is to determine if transitioning to ASTM-based procedures could reduce material and production costs for the aerosol industry while maintaining or enhancing safety, potentially laying the groundwork for future regulatory updates. This initiative is part of a broader effort by the Department of Transportation’s PHMSA to standardize safety testing across the industry, ensuring consistent performance criteria for all aerosol containers regardless of manufacturer. The research will analyze data from existing special permits and compare outcomes with results from the proposed ASTM tests to identify any gaps or improvements in current practices. Responses are due by August 1, 2026, and all information submitted will inform the agency’s evaluation of potential rulemaking changes. The solicitation, identified as 693JK326RFI02, is managed by the 693JK3 Acquisition Services Division located in Washington, D.C., with Dwayne Cross serving as the primary point of contact for inquiries.
