Individuals or businesses can't join ISO. Membership of ISO is only open to national standards institutes or similar organizations that represent standardization in their country (one member in each country). It's important to realize that companies that apply or certify ISO standards are not ISO members. Find out more about ISO members.

Conformity assessment involves a set of processes that show your product, service or system meets the requirements of a standard. It's important to note that ISO doesn’t provide certification or conformity assessment. Find out more about conformity assessment.

No. ISO doesn’t provide certification or conformity assessment. Find out more about how conformity assessment and certification works.

Only ISO, ISO members, and ISO technical committees (TCs) are allowed to use the ISO logo and ISO short name in accordance with ISO Policies.  Read more about our name and logo.

At ISO we are not involved in certification, and do not issue certificates, but we we have created some useful information for those looking for a certification body.

ISO itself does not have data on equivalent standards (such as national or regional standards). However, a number of ISO members are able to provide this information. Therefore, please contact the ISO member in your country.

Working through the ISO community, it is the people who need the standards that decide. A particular industry or business sector can communicate its need for a standard to their national ISO member; the idea is then proposed to ISO as a whole.

If accepted, the project is assigned to an existing technical committee. Proposals may also be made to establish technical committees to cover new scopes of technological activity. In order to use resources most efficiently, ISO only develops new standards for which there are clear market requirements.

If you feel there is a need for a standard in your sector, please contact your ISO member.

Developing, publishing and maintaining ISO standards incurs a cost, and revenues from selling them helps ISO and its members to cover an important part of these costs. Charging for standards allows us to ensure that they are developed in an impartial environment and therefore meet the needs of all stakeholders for which the standard is relevant. This is essential if standards are to remain effective in the real world. ISO and its members offer a number of options to access ISO standards. Contact us or your national ISO member to find the best option for your needs.

ISO is a non-governmental organization (NGO). Therefore, unlike the United Nations, the national members of ISO are not delegations of the governments of those countries. Our national members are the national standards bodies, or equivalent organizations, in their country. Some of them are wholly private sector in origin, others are private sector organizations but have a special mandate from their governments on matters related to standardization, and others are part of the governmental framework of their countries. In addition, government experts often participate in ISO's standards' development work. So, while ISO is an NGO, it receives input from the public sector as it does from the private sector.
