Certifications and Standards

Keeping our Products Safe, Accessible, and Sustainable


The American Society of Mechanical Engineers (ASME) serves the engineering community through quality learning, the development of codes and standards, certifications, research, conferences and publications, government relations, etc. The plumbing industry has adopted the ASME A112.18.1/CSA B125.1 and ASME A112.19.14 (for dual flush toilets), issued jointly by the American Society of Mechanical Engineers (ASME) and the Canadian Standards Association, for minimum product requirements.


The International Association of Plumbing & Mechanical Officials (IAPMO) community of plumbing experts plays a vital public health role in assuring access to clean water and sanitation. Gerber uses IAPMO to test and certify our products in regards to BOTH the product’s performance standard AND the Uniform Plumbing Code (UPC).
