Multilateral Recognition Arrangement Documents (ML Series)
The primary purpose of IAF is to establish Multilateral Recognition Arrangements (MLA) between its accreditation body members in order to contribute to the freedom of world trade by eliminating technical barriers to trade.
The purpose of the MLA is to allow accreditations and the certificates issued by certification/registration bodies accredited by members of the MLA to be recognised by the other members of the MLA. The objective is that the MLA will cover all accreditation bodies in all countries in the world, thus eliminating the need for suppliers of products or services to be certified in each country where they sell their products or services (certified once – accepted everywhere).
Membership of the MLA is based on peer evaluation of each applicant for membership of the MLA and continued surveillance of each member to ensure and confirm that all the members of the MLA operate their accreditation programs, and are implementing the Guidelines, consistently and in an equivalent way.
The accreditation programs of members of the MLA are based on relevant ISO/IEC Guides. In order to ensure that the various programs are operated in an equivalent way, IAF issues Guidance to the Application of the various ISO/IEC Guides.  The IAF Guidance documents are based on the experience of accreditation bodies in applying the ISO/IEC Guides in practice, and represent agreement among IAF members on best practice in the application of those Guides.  Accreditation bodies which are members of the MLA are required to adopt the IAF Guidance as part of their general rules of operation.
