Simply put, laboratory accreditation refers to CNAS conducting a review of the technical and management capabilities of the organization applying for accreditation, in accordance with relevant international or national standards and based on relevant standards or normative documents, to confirm that the organization has the ability to issue certificates or reports. Certificates or reports issued within its recognized scope according to the prescribed procedures should be trustworthy. The CNAS logo can be used on the reports of projects that have been recognized, and it is also a third-party proof of formal recognition of their work ability, which is conducive to promoting widespread trust, acceptance, and use by both society and trade parties.
