U.S. Environmental Protection Agency (EPA) is proposing to add a new quality control test method for measuring formaldehyde air emissions from composite wood products as part of routine updates to its Formaldehyde Emission Standards for Composite Wood Products under the Toxic Substances Control Act (TSCA). The proposed method for ISO 12460-2:2024(en) Wood-based panels — Determination of formaldehyde release Part 2: Small-scale chamber method, would provide manufacturers and testing laboratories with an additional, internationally recognized tool to help ensure consistent, high-quality emissions data across the industry. Along with adding this new method, EPA is proposing technical updates to align the rule’s voluntary consensus standards with the most current versions issued by standard-setting organizations… These updates are routine and aim to maintain consistency with industry practices. They do not alter any existing health or safety protections for consumers or workers and are unrelated to the agency’s ongoing risk evaluation for formaldehyde.
