Link to accreditation

Producer competence accreditation typically follows ISO 17034, implemented in China as CNAS-CL04. Applicants need both regulatory readiness and an effectively operated management system under the accreditation criteria.

Core coaching topics

• System & roles: documents, internal audit and management review
• Production control: materials, process confirmation and change control
• Characterization: assignment schemes, method validation and uncertainty
• Homogeneity & stability studies and storage/transport conditions
• Metrological traceability and certificate/label information
