Services by CompanyWelcome to the New Home of NSF International’s Former BuildCert Program

BuildCert (now called NSF International) is a product certification program for plumbing products such as thermostatic mixing valves, tempering valves and chemical inhibitors. This program evaluates products against leading industry certification schemes, including TMV2, TMV3, Chemical Inhibitor Approval Scheme (CIAS) and Distribution Tempering Control valve (DTC). While this program was created in the United Kingdom, it services clients around the world.

Effective August 1, 2017, BuildCert changed its name to NSF International to align with NSF’s corporate branding and mission. NSF International is a global independent organization that writes standards, and tests and certifies products for the water, food, health sciences and consumer goods industries to minimize adverse health effects and protect the environment.

For information on products certified under this program, please visit the product-specific pages via the links to the right. Current customers of the former BuildCert can access forms and paperwork for projects on the “Publications” tab of these pages, or by contacting their account manager directly.

For more information on these changes or the NSF International brand, please contact us at wales@nsf.org.
