As a full member of International Accreditation Forum (IAF) and Pacific Accreditation Cooperation (PAC) since 1996, SAK has actively participated in the works of the international and regional forum of conformity assessment activities by attending IAF and PAC meetings, hosting international events such as the PAC annual meeting in 2004, etc. To facilitate trade and market access of companies, SAK joined IAF MLA(Multilateral Recognition Arrangement) for QMS in 1999 and EMS in 2004, which contribute to eliminating the need for duplicative certifications and saving time and costs by ensuring that an accredited certificate may be relied upon anywhere in the world.

The MCAA provides "for the recognition of the acceptability of the results of each party's assessment and accreditation program based upon the determination of equivalence."

With regard to standardization, SAK serves as a national secretariat of ITC 207, designated by KATS, a national standard body of Korea for the distribution of information on and deliberation of international standards on Quality Management and Environmental Management. SAK also is a member of national committee for ISO/SATCO(Committee on Conformity Assessment), in which SAK has reviewed and provided inputs of those draft standards being developed by ISO/SATCO.

In addition to its participation in international and regional bodies, SAK has maintained a close relationship with other national accreditation bodies. SAK has conducted annual meetings with JAB(Japan) to share experience and exchange information on accreditation system since 2000. As the IAF Cross Frontier Policy has been effective, SAK will enhance cooperation with foreign accreditation bodies to give confidence in certification to the market.
