CAPA certification is the most effective standards-setting, quality assurance program of its kind. It establishes objective, measurable Quality Standards and Specifications for replacement parts for metals, plastics, lights, foam rubber and bumpers.

Each Standard provides detailed testing and inspection procedures to ensure the quality of the parts covered by that Specification. All test procedures utilize nationally recognized tests such as those of the American Society for Testing and Materials (ASTM) and Society of Automotive Engineers (SAE) and are publicly available.

Staying a Step Ahead.

Because technology, manufacturing and the science of testing continually advance, so do we. Our Technical Committee, made up of experts in the collision repair, quality control and replacement part industry, continually reviews, updates and refines CAPA Standards as required, to assure the continued high quality of CAPA Certified parts and expand the categories of parts we evaluate.
