What Does ANSI Stand For?
The American National Standards Institute is the administrator and coordinator of the U.S. private sector voluntary standardization system. ANSI oversees the creation, promotion, and use of standards that impact businesses in practically any sector, ranging from construction to agriculture. ANSI is also the U.S. member body to ISO (International Organization for Standardization).
ANSI’s Mission is:
To enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards and conformity assessment systems, and safeguarding their integrity.
When American National Standards Institute (ANSI) adopts an existing standard, it retains the original standard number of the issuing agency and assigns an “ANSI” prefix.
How the ANSI Year Can Help You Identify or Confirm an Appliance’s Age:
Most manufacturers implement new ANSI standards within a year of them being released, but others are often years behind.
When you locate the ANSI standard you can know for sure that the appliance is not OLDER than the ANSI year. This can be helpful in confirming the age but is not always reliable when it comes to dating the appliance EXACTLY because the appliance could be several years older than the ANSI year.
See the example below, where the ANSI year on this Rheem water heater is 2002 but the water heater was actually manufactured in December of 2003:
The bottom line: Use the ANSI to confirm that the appliance isn’t OLDER than the year listed, but don’t rely on it for the exact year of manufacture.
