International Organization for Standardization (ISO) is a standards-making body, similar to the International Electrotechnical Commission (IEC).
ISO works with National Committees in different countries in preparing and maintaining standards.
ISO is the largest developer and publisher of international standards in the world.
The ISO standards making process, similar to many other standards making processes, is handled by various technical committees (TC).
The TCs are the key bodies that drive the standardization and comprise experts from the national committees and are a completely voluntary effort.
