Technical Committees

Each TC is a diverse group of experts representing a broad range of perspectives and interests, including consumers, manufacturers, regulators, supply chain professionals, and more. 

As a TC member, you will review proposals for new or revised standards and work collaboratively to achieve consensus through balloting in our transparent process.

Stakeholders

Stakeholders can submit, review, and comment on proposals for new standards or revisions to existing standards. While these individuals cannot vote, the TC considers their input during the standards voting process. Since standards affect everyone, all are welcome to participate as stakeholders.
