ISO, the International Organization for Standardization, is a non-governmental organization that develops and publishes international standards. These standards provide guidelines and specifications for a wide range of products, services, and systems to ensure quality, safety, and efficiency.

There are many different ISO standards that cover various industries and fields. Some of the more common ones include:

ISO 9001: Quality management systems

ISO 14001: Environmental management systems

ISO 27001: Information security management systems

ISO 45001: Occupational health and safety management systems

ISO 22000: Food safety management systems

ISO 50001: Energy management systems

ISO 9001 is perhaps the most well-known of these standards. It specifies requirements for a quality management system and is applicable to any organization, regardless of size or industry. It helps organizations to consistently meet customer requirements and improve their overall performance.

ISO 14001 is another popular standard that deals with environmental management. It sets out requirements for an organization to develop and implement an environmental management system (EMS) and to continually improve its environmental performance.

ISO 27001 is a standard for information security management systems (ISMS). It provides a framework for establishing, implementing, maintaining, and continually improving the security of an organization's sensitive information.

ISO 45001 is a standard for occupational health and safety management systems (OHSMS). It helps organizations to prevent work-related injuries and illnesses and to create a safe and healthy work environment.

ISO 22000 is a standard for food safety management systems. It applies to all organizations in the food chain, from primary production to final consumption, and helps to ensure that food is safe and suitable for consumption.

ISO 50001 is a standard for energy management systems. It helps organizations to improve their energy efficiency and reduce their energy costs and greenhouse gas emissions.

These are just a few examples of the many different ISO standards that exist. ISO standards provide a common set of guidelines and specifications that organizations can follow to improve the quality, safety, and efficiency of their products, services, and systems.
