We welcome applications from all conformity assessment bodies of any size or affiliation worldwide, provided they meet the scheme-specific accreditation requirements defined in Section 6 of the Accreditation Manual.
For schemes where the scheme owner has appointed ASI Assurance as its assurance provider, conformity assessment bodies must hold both accreditation from the relevant Accreditation Body and separate ASI Approval from ASI Assurance.
Start your application by filling in the application form in English and send it to [email protected] for review.
You’ll need to demonstrate that you comply with scheme-specific accreditation requirements, including having a documented quality management system, and clear structures to safeguard impartiality.
