Examples of markings are as follows: Example 1: A fixed length round bar made of T2 (T11050), M30 (hot extruded) state, high-precision, 40 mm diameter, 2000 mm length, is marked as: Round bar YS/T 649-T2 M30 high-Φ40x2000 OR: round bar YS/T 649-T11050 M30 high-Φ40x2000 The surface quality of the bar shall be inspected visually.5 Inspection rules5.1 Inspection and acceptance 5.1.1 The supplier’s technical supervision department shall conduct inspections, to ensure that the product quality complies with the provisions of this standard and the purchase order (or contract); meanwhile fill in the quality certificate. 5.1.2 The purchaser shall re-inspect the received product, in accordance with the provisions of this standard and the purchase order (or contract). If the re- inspection result does not conform to the provisions of this standard or the purchase contract, it shall be submitted to the supplier, in written form, to be settled, through negotiation, between the supplier and the buyer. For the objections related to surface quality and dimensional deviation, it shall be filed, within one month from the date of receipt of the product. For the objections related to other properties, it shall be filed, within three months from the date of receipt of the product. If arbitration is required, arbitration sampling shall be conducted jointly by the supplier and the buyer. 5.2 Group-batching The bars shall be submitted for acceptance in batches. Each batch shall be composed of the products of the same designation, state, specification. The mass of each batch shall not exceed 5000 kg. 5.3 Inspection items 5.3.1 Each batch of bars shall be inspected for chemical composition, external dimensions, internal quality, surface quality. 5.3.2 Each batch of bars shall be inspected for mechanical properties (tensile test or hardness test). Choose either the tensile test or the hardness test. If it is not specified in the contract, the tensile test shall be carried out. When selecting the tensile test, if the buyer also requires a hardness test AND it is specified in the contract, the hardness test shall also be carried out. The results of the hardness test are for reference only. When the hardness test is selected, if the buyer also requires a tensile test AND it is specified in the contract, a tensile test shall also be carried out. The results of the tensile test are for reference only. 5.4 Sampling Bar sampling shall meet the requirements of Table 8.
