There are three grades of membership:
- Accreditation member
- Institutional member
- Individual member
Accreditation member: these are organisations whose corporate purpose is to provide accreditation services to certification bodies and to inspection and test bodies. They are identified as a unique group for membership of IAU because of their contribution and influence to product and systems quality assurance.
Institutional member: These are corporate bodies representing the interests of members and other stakeholders. They are generally non – profit making and membership organisations serving the needs of a particular industry sector or professional group but may also speak on behalf of consumer groups or other stakeholder interest
Individual member: This may be a person or a corporate business. It will have a fairly well defined and specific interest in its own well-being but nonetheless is not denied the opportunity to contribute to the global environment regarding quality assurance.
