DAS Certification Limited, the UK Head Office is accredited by the United Kingdom Accreditation Service (UKAS), which was formally known as the National Accreditation Council for Certification Bodies. UKAS, acting on behalf of the Secretary of State for Trade and Industry, and in conjunction with the European Cooperation for Accreditation (EA), impose strict rules for registrars; particularly with regard to auditor's competence, independence and impartiality. UKAS regularly visit DAS to satisfy themselves that the rules are being followed.
There are currently more than 50 International Accreditation Forum (IAF) members representing different countries who have signed the Multilateral Agreement (MLA). UKAS is signatory to this agreement. Certificates issued by bodies accredited by IAF members are relied upon all over the world because the MLA assure customers that the certificate is credible (refer to http://www.iaf.nu)
