The International Organization for Standardization (ISO) is an independent, non-governmental organization that develops and publishes voluntary international standards to ensure quality, safety, and efficiency. It was founded in 1946 and has members from 162 countries. ISO follows a consensus-based process to develop standards through technical committees with experts from member countries. Popular ISO standards cover areas like quality management, information security, environmental management, and more. Certification to standards is performed by external certification bodies, not ISO directly.
