The international standards used for company quality are published by _____________.

The correct answer is ISO because the International Organization for Standardization (ISO) is the body responsible for developing and publishing international standards for a wide range of industries, including quality management. The standards established by ISO, such as ISO 9001, provide a framework for organizations to improve their quality management systems, thereby enhancing customer satisfaction and operational efficiency. ISO standards are globally recognized and are used by organizations to ensure that their products and services consistently meet quality requirements and comply with regulations.

Other organizations listed serve different purposes: ANSI (American National Standards Institute) is focused mainly on overseeing the development of American national standards, ASTM (formerly known as the American Society for Testing and Materials) develops and publishes voluntary consensus technical standards for materials, products, systems, and services, and IEC (International Electrotechnical Commission) is dedicated to standardizing electrical and electronic technologies. While these organizations contribute to standardization, ISO is specifically authoritative in the global context of quality management standards.
