ISO is a worldwide alliance of national standards bodies. The work of preparing International Standards is generally carried out from first to last ISO technical committees.

Each member body paying attention to a subject for whom a technical committee has been entrenched has the right to be represented on that committee. International organizations, governmental and non-governmental, in link with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) lying on all matters of electrotechnical standardization.

International Standards are the moral fiber of our society, ensuring the safety and quality of products and services, facilitating international trade and refining the environment in which we live in. International Standards are strategic tools and guidelines to help companies undertake some of the mainly demanding challenges of modern business.
