Accreditation is an endorsement of a certification body's independence, integrity and technical competence. It enables the certification body to use the mark of accreditation and to offer its services with confidence nationally and worldwide.

The SWISO ISO 9000 and 14000 certification schemes are accredited by SAS (Swiss Accreditation Services), a globally recognised organization providing Management Systems accreditation to certification bodies worldwide. This international endorsement strengthens SWISO certification's stature as a credible certification authority.
