What is the full form of ISO?
The name, "ISO" is not an acronym but was derived from the Greek word "isos" meaning "equal". (The relation to standards is that if two objects meet the same standard, they should be equal.) This name eliminates any confusion that could result from the translation of "International Organization for Standardization" into different languages which would lead to different acronyms.
ISO (International Organization for Standardization) is the world's largest developer and publisher of International Standards. ISO is a network of the national standards institutes of 157 countries, one member per country, with a Central Secretariat in Geneva, Switzerland.
