Certified Ratings Program (CRP)

AMCA International’s Certified Ratings Program (CRP) assures that a product line has been tested and rated in conformance with AMCA International’s test standards and rating requirements.

Performance seals are documented and displayed on equipment after a product has been tested and its cataloged ratings have been approved by AMCA International’s staff. Each certified product line is subject to continued check tests in AMCA International’s laboratories. All certified products are open to challenge testing that any third party or competing manufacturer may initiate. Participation in AMCA International’s CRP is voluntary and is open to members and non-members. All certified products are updated and listed by AMCA International.

Learn about the alternative types of certification available under CRP, such as CRP Ai, CRP As, CRP B, CRP L, and CRP M.


Any company or corporation - whether an AMCA International member or not - is eligible to participate in AMCA International’s Certified Ratings Program.


AMCA International’s Certified Ratings Program continues to expand throughout the world and is recognized in all industrialized countries.
