Most countries only have a single Accreditation Body representing their economy in the IAF MLA. The two exceptions are the United States with American National Standards Institute (ANSI), American National Standards Institute - American Society for Quality National Accreditation Board (ANAB, a subdivision of ANSI), American Association for Laboratory Accreditation (A2LA), and International Accreditation Service (IAS) as signatory members, and United Accreditation Foundation as Full Member of IAF (International Accreditation Forum) Europe with Germany's Technischer Überwachungsverein (TÜV), and Korea which is represented by Korea Accreditation Board (KAB) and Korean Accreditation System (KAS). These listings are current as of March 2012, but will likely change in the future as more Accreditation Bodies undergo the required peer evaluations in order to become signatory members of the MLA.
