It gives value and credence to the certification. An accredited certificate is usually the only type accepted in tenders for new business.

Accreditation is the approved recognition of a certification body to perform certifications against different standards. Every country has its own regulated accreditation body. These bodies issue accreditations to certification bodies such as URS Certification. Accreditation is achieved by demonstrating prescribed controls and systems are in place. These requirements are also defined by international standards (for systems certification this is ISO 17021).
 

Once accredited, certification bodies can offer accredited certification against standards such as ISO 9001 to any organisation that receives a successful audit.

ISO is an abbreviation for the International Organization for Standardization based in Geneva. This organisation issues international standards called ISO.

Certificates for a limited time period, usually for three years, are issued by an accredited certification body. In order to keep the certificate valid, a periodic audit is performed, typically once a year. If fundamental deviations from the standard requirements are discovered, the extreme measure of the certificate withdrawal can be applied. This is a very rare, exceptional and unpleasant situation. Therefore, when a company decides to implement and follow an ISO standard, it is a voluntary commitment to continuous improvement and development, which is worth the company’s effort.
