This link takes you to the website for the International Organization for Standardization. ISO is a network of the national standards institutes of 148 countries, on the basis of one member per country, with a Central Secretariate in Geneva, Switzerland, that coordinates the system. It is a non-governmental organization; the members are not delegations of national governments.
The web site is rather extensive with information about ISO, products & services, ISO 9000/14000; standards development; membership information and how to contact ISO.
