Are ANSI and IEC the same ?

Title: Are ANSI and IEC the same? A comparison of two international standardization organizations


The International Electrotechnical Commission (IEC) and the American National Standards Institute (ANSI) are two prominent organizations that develop and publish international standards for electrical, electronic, and related technologies. Both organizations have a similar goal of providing a platform for collaboration and harmonization of standards, ensuring interoperability and global acceptance. However, there are notable differences between ANSI and IEC that are worth exploring.

Geographical Scope:

ANSI primarily caters to standards required within the United States, whereas IEC focuses on international standards. ANSI is a domestic organization that operates primarily within the United States, with a significant presence in Canada, Mexico, and other countries. In contrast, IEC is an international organization that operates on a global scale, with a headquarter in Geneva, Switzerland.

Standards Development:

IEC brings together experts from different countries to develop and promote standards that ensure safety, efficiency, and compatibility of electrical systems. The IEC standards cover a wide range of areas, including power generation, transmission, distribution, renewable energy, and automation. These standards are developed through a consensus-based approach, which allows for collaboration among experts from different countries.

ANSI, on the other hand, develops and publishes standards for the American industry. These standards are primarily focused on safety, efficiency, and accessibility, and are developed through a consensus-based approach.


In conclusion, ANSI and IEC serve similar purposes, but they have notable differences in their geographical scope, standards development approach, and scope. While both organizations have a similar goal of providing standardized frameworks for electrical, electronic, and related technologies, the differences between them are important to consider when deciding which organization to follow for specific standards.
