Standards Projects in Development
The Motion + Power Manufacturers Alliance (MPMA) maintains an active standards development program that supports quality, reliability, and innovation across mechanical power transmission manufacturing.
Through collaboration among engineers, manufacturers, and technical specialists, MPMA committees evaluate industry needs, update existing standards, and develop new technical guidance for gears, bearings, and related components.
MPMA provides visibility into current standards activity, including public review opportunities, committee meetings, and projects in development, ensuring members and stakeholders can stay informed and contribute to shaping the industry’s technical guidance.
Public Review
Participate in the Standards Development Process
Public review is an important step in the standards development process. It provides industry professionals the opportunity to review draft standards and submit feedback before documents are finalized.
Input from manufacturers, engineers, and other stakeholders helps ensure that standards remain practical, accurate, and aligned with current manufacturing practices.
If you would like to participate in public review, please contact us to be added to the review distribution list.
Upcoming Public Review
Public review is currently open for the following documents. Comments should be submitted by the deadline listed.
ABMA B3.2-YYYY,
Rolling Element Bearings – Aircraft Engine, Engine Gearbox, and Accessory Applications – Surface Visual Inspection
Comments due April 26, 2026
Standards Projects in Development
MPMA maintains a portfolio of active standards projects that address evolving technologies, manufacturing practices, and industry needs.
Projects may involve:
- Development of new standards
- Revision of existing standards
- Adoption of international standards
- Reaffirmation of current documents
Each project is guided by a committee or working group and led by an industry subject matter expert.
Upcoming Standards Committees & Working Group Meetings
MPMA technical committees and working groups meet regularly to advance standards development, review technical topics, and coordinate project activity.
Meetings include representatives from across the power transmission industry and provide an opportunity for members to contribute expertise and collaborate on technical guidance.
