Is ANSI under ISO?

In the world of technical standards, ANSI and ISO are two prominent organizations that play a crucial role in ensuring consistency and compatibility across various industries. However, understanding the relationship between ANSI (American National Standards Institute) and ISO (International Organization for Standardization) can be somewhat convoluted. This article aims to provide an in-depth analysis of whether ANSI falls under ISO and shed light on their respective roles in the realm of technical standards.

What is ANSI?

ANSI, established in 1918, is a non-profit organization that operates within the United States. It is responsible for developing and promoting voluntary consensus standards for numerous fields, including technology, engineering, and safety. These standards are created through a collaborative process that involves stakeholders from various sectors. ANSI's main objective is to ensure interoperability, quality, and safety in products and services offered in the American market.

What is ISO?

On the other hand, ISO is an international organization founded in 1947 with a broader scope. It comprises national standards bodies from different countries, including ANSI, and serves as a global platform for standardization efforts. ISO develops and publishes international standards that facilitate global trade and cooperation. While ANSI focuses mainly on the American market, ISO sets standards with a worldwide perspective, harmonizing practices across borders and enabling organizations to collaborate seamlessly.

The Relationship between ANSI and ISO

It is important to note that ANSI and ISO operate independently despite their collaboration. ANSI is the official representative of the United States in the ISO network and actively participates in its decision-making processes. This collaboration ensures that the interests of the American market are adequately represented in global standardization efforts. However, ANSI does not fall directly under ISO's authority, nor does it subordinate its own standards to ISO's.

In some cases, ANSI standards are adopted by ISO, meaning that they become international standards. This adoption typically occurs when ANSI standards receive widespread recognition and usage beyond the United States. Consequently, ANSI's involvement in ISO enables the global community to benefit from proven and widely accepted American standards. Conversely, ISO standards may also serve as a foundation for developing ANSI standards, ensuring consistency and compatibility between national and international guidelines.


Though ANSI and ISO both contribute significantly to the establishment of technical standards, their relationship is best described as one of collaboration rather than hierarchy. While ANSI focuses primarily on the American market, ISO operates at a global level, promoting harmonization and facilitating international trade. The adoption of ANSI standards by ISO and vice versa ensures the coherence and interoperability of standards across regions. Ultimately, both organizations play integral roles in fostering safety, quality, and efficiency across various industries.
