ACMA Announces the Revision of Unified Emission Factors (UEF) For Open Molding and Other Composite Processes

Arlington, VA — (July 3, 2025) The American Composites Manufacturers Association (ACMA), an ANSI-accredited Standards Developing Organization (SDO), has announced the revision and redesignation of ANSI/ACMA UEF-1-2019 Estimating Emission Factors from Open Molding and Other Composite Processes. The project was published in the June 6, 2025, edition of the American National Standards Institute (ANSI) Standards Action (VOL. 56, NO. 23). Public comments on Project Initiation Notification System (PINS) are welcome through July 6, 2025.

The Unified Emission Factors (UEF) for Open Molding and Other Composite Processes standard provides scientifically backed methods for estimating air emissions from various composites manufacturing processes, including open molding. These estimates are essential for a wide range of applications, such as:

• Emission inventories
• Environmental permit applications
• Regulatory compliance reports
• Toxics Release Inventory (TRI) reports submitted to the U.S. Environmental Protection Agency (EPA)
• Internal business planning and sustainability initiatives

Participation is open to all interested parties regardless of ACMA membership. ACMA encourages involvement in the standards development process through two key groups:

• Relevant Committee – Responsible for drafting the revised standard and addressing public comments.
• Consensus Body – Serves as the official voting group that reviews and approves the draft before the final 45-day ANSI public review.

To express interest, individuals must complete the ACMA Interest Form. ACMA leadership and the Committee Chair will finalize the composition to ensure balanced representation.

For details on how to participate or to stay informed about ACMA’s standards development efforts, please visit ACMA’s Standards in Progress page or email Standards@ACMAnet.org.-voting roles.
