2. Check the quality certification documents of the materials and include them in the engineering and technical files.
3. After the material enters the site, the material inspection report shall be issued according to the specification.
4. When all the indicators of the physical properties of the material meet the standards, it is qualified; If an index does not meet the requirements of the standard, the index should be re-sampled in the tested product for re-inspection, and the re-test result meets the requirements of the standard, and the batch of materials will be judged to be qualified.
