Comparative Verification Testing, Type Testing, Production License Testing, Voluntary Product Certification Testing

Comparative verification testing: is a form of testing specified in the "Quality Management Regulations for Cement Production Enterprises." It requires enterprises with a daily clinker production capacity of 4,000 tons or more, as well as those producing special cement, to regularly conduct comparative verification with the National Cement Center.

Type testing: is a form of testing conducted according to the frequency and parameters specified in product standards.

Production license testing: is a form of testing carried out in accordance with the requirements of the implementation rules when enterprises apply for a new license or renewal.

Voluntary product certification testing: is a form of testing conducted when enterprises apply for product certification.
