Which organization develops international standards in various fields?

The correct answer is ISO, which stands for the International Organization for Standardization. ISO is responsible for establishing and publishing international standards across a wide range of industries and sectors. The organization works to ensure quality, safety, efficiency, and interoperability of products and services globally.

ISO standards are developed through a collaborative process that involves experts from various nations, ensuring that they are applicable and beneficial on an international scale. These standards cover a multitude of areas, including technology, manufacturing, and service provision, facilitating trade and improving quality across borders.

While ANSI (American National Standards Institute) also develops standards, it primarily focuses on U.S. standards rather than international ones. UL (Underwriters Laboratories) is known for safety testing and certification, particularly in the fields of electrical and fire safety. NIST (National Institute of Standards and Technology) is a U.S. federal agency that focuses on measurement standards and technology but does not have the international scope that ISO does. Thus, ISO is the appropriate choice for an organization that develops international standards.
