ANSI Standards

CEMA: An ANSI Accredited Standards Developer

As an ANSI Accredited Standards Developer, the Conveyor Equipment Manufacturers Association (CEMA) plays a leading role in setting the standards that shape the safe and efficient design, manufacturing, and application of conveyor equipment. As ANSI states, “accreditation by ANSI as a standards developer represents a public statement of the value placed on an open and equitable consensus development process.” ANSI is an independent, nonprofit organization dedicated to boosting the global competitiveness of businesses through facilitating voluntary consensus standards and conformity assessment systems and safeguarding their integrity.

CEMA develops and maintains 14 American National Standards (ANSI/CEMA) that are widely recognized across the industry. These standards represent decades of consensus-driven expertise from manufacturers, engineers, users, and other key stakeholders in the conveyor sector.

Why ANSI Matters

CEMA’s ANSI accreditation means our standards development process is:

  • Open and transparent
  • Consensus-based
  • Balanced across stakeholders
  • Rigorous in due process and periodic review

This ensures every ANSI/CEMA standard reflects both industry best practices and evolving technologies—promoting safety, compatibility, and efficiency across the material handling field.
