Who are the auditors and appraisers in concrete strength evaluation?
The signature is generally: 1. Three people: tester, auditor and approver. 2. Four people: testers, inspectors, auditors and approvers. 3. Five people: testers, calculators, inspectors, auditors and approvers. It depends on the situation of each unit and industry. This kind of appraiser is generally rare. I don't know. Experiments and calculations are clear.
