DIN vs. ANSI

Posted by Baelz North America on Jun 28, 2018 10:00:00 AM

The American National Standards Institute (ANSI) is a nongovernment, nonprofit organization that coordinates U.S. industry standards with international standards so that U.S. products can reach the global market. In essence, ANSI serves as an accreditation body for standards developed by other organizations, companies, consumer groups, and government agencies.

The Deutsches Institut für Normung (DIN), or the German Institute for Standardization, serves a similar function. However, DIN is a government organization that embodies German concerns within the framework of European and International standards. DIN has a wide reach, and over 30,000 DIN standards provide comprehensive coverage for various products and technologies.

The Difference Between ANSI and DIN

DIN is most commonly specified in European countries, while ANSI is usually specified in the United States. Therefore, the majority of factories in North America are likely to have piping that is ANSI certified, while similar plants in European countries have DIN piping.  When working with piping that uses the ANSI standard, the flange bolt patterns, face-to-face valve dimensions and pressure requirements will all be in standard measurements (inches and psi). DIN standards use metric measurements (mm and bar) to measure the valve and flange sizes and pressures.

In general, US-based companies, such as those in the automotive and food industries, choose to work with ANSI, especially if manufacturing is done in the United States. European firms typically employ DIN, even if manufacturing occurs in the United States.
