ISO (International Organization for Standardization) is a network of standards institutes from 159 countries with a central office in Geneva, Switzerland, that coordinates the system.

ISO is a non-governmental organization that forms a bridge between the public and private sectors, and is the largest standards organization in the world.

• Many of its member institutes are part of the governmental structure of their countries, or are mandated by their government.

• Some members have their roots uniquely in the private sector, having been set up by national partnerships of industry associations.

Therefore, ISO enables a consensus to be reached on solutions that meet both the requirements of business and the broader needs of society.
