Certification can be a useful tool to add credibility, by demonstrating that your product or service meets the expectations of your customers. For some industries, certification is a legal or contractual requirement.
At ISO, we develop International Standards, such as ISO 9001 and ISO 14001, but we are not involved in their certification, and do not issue certificates. This is performed by external certification bodies, thus a company or organization cannot be certified by ISO.
However ISO’s Committee on Conformity Assessment (CASCO) has produced a number of standards related to the certification process, which are used by certification bodies. Read more about CASCO standards.
