When arbitrating, it shall be performed as per the provisions of GB/T 351. 4.5 Surface quality The surface quality of strip shall be examined visually. 5 Inspection Rules 5.1 Inspection and acceptance 5.1.1 The strip shall be inspected by the quality supervision department of the supplier; ensure that the product quality conforms to the provisions of this Standard and order sheet (or contract); and fill in the product quality certificate. 5.1.2 The purchaser shall be re-inspected the product received according to the provisions of this Standard and order sheet (or contract); if the re-inspection results are inconsistent with the provisions of this Standard and order sheet (or contract), it shall be submitted to the supplier within 3 months in written form, then shall be solved through negotiation between the supplier and purchaser. The problems that belong to 5.5.2 When the shape size, permissible deviation and surface quality of strip are disqualified, then such batch of strip is disqualified. 5.5.3 When there is disqualified specimen in mechanical property and electrical property test results, take double quantity of specimens from such batch of strips (including the originally disqualified roll of strip in the test) to re-test; if the re-test results are qualified totally, then the whole batch of products are qualified. If there is still disqualified product in the re-test results, then such batch (or such roll) of strip is disqualified; then the supplier is allowed to check roll by roll, only the qualified roll can be delivered. 6 Marking, Package, Transportation, Storage, Quality Certificate The marking, package, transportation, storage and quality certificate of strip shall conform to the provisions of GB/T 8888. 7 Order Sheet (or Contract) Contents The order sheet (or contract) ordering the materials listed in this Standard shall include the following contents. a) Product name; b) Grade; c) Supply state; d) Size specification; e) Hardness (if required); f) Weight; g) This Standard number; h) Others. ......
