Plate Sn2 2×300×800 GB 2528--894 Technical requirements
4.1 Chemical composition
The chemical composition of the plate shall comply with the provisions of GB728. 4.2 Surface quality
4.2.1 The surface of the plate shall be smooth and clean. Cracks, bubbles, peeling, inclusions and other defects are not allowed. 4.2.2 The cross section of the plate shall not be delaminated.
4.2.3 Slight, localized scratches, spots, pits, roller marks and repair marks on the surface of the plate that do not exceed the allowable deviation of the plate thickness shall not be considered as a basis for scrapping.
5 Test method
5.1 The arbitration analysis method for the chemical composition of the plate shall be carried out in accordance with the provisions of GB3260. 5.2 The outer dimensions of the plate shall be measured with measuring tools of corresponding accuracy. 5.3 The surface quality of the plate shall be visually inspected. 6 Inspection rules
6.1 Inspection and acceptance
6.1.1 The plate shall be inspected and accepted by the supplier's technical supervision department, and the product quality shall be guaranteed to meet the requirements of this standard. 6.1.2 The buyer shall re-inspect the received products in accordance with the provisions of this standard. If the re-inspection results do not conform to the provisions of this standard, the buyer shall submit the matter to the supplier within three months from the date of receipt of the product, and the supplier and buyer shall negotiate to resolve the issue. 6.2 Batches
The plates shall be submitted for acceptance in batches. Each batch shall consist of plates of the same brand, thickness specification, manufacturing method and state. Batch weight is not more than 2t6.3 Inspection items
Each batch of plates shall be inspected for chemical composition, external dimensions and surface quality. 6.4 Sampling location and sampling quantity
6.4.1 During the melting and casting process, the supplier shall take a sample from each furnace for chemical composition inspection6.4.2 The buyer shall randomly take a sample from each batch of plates for chemical composition inspection. 6.4.3 The thickness of the plates shall be measured within a range of not less than 100mm from the top corner and not less than 10mm from the edge. The thickness deviation outside the measurement range shall not be used as a basis for scrapping.
6.4.4 The plates shall be subsequently measured for external dimensions and surface quality inspection. 6.5 Repeated test
If the chemical composition test result is unqualified, double samples shall be taken from the batch for re-inspection. If there is still one unqualified sample in the re-inspection result, the entire batch shall be scrapped.
7 Packaging, marking, transportation and storage
Packaging, marking, transportation and storage shall be carried out in accordance with the provisions of GB8888. Additional remarks:
