3 Requirements
3.1 Product classification
4 Test Methods
4.1 Chemical compositions
The arbitration analysis of the ingot chemical compositions shall be carried out according to the method specified in GB/T 13748. Where GB/T 13748 does not provide the provisions, it shall be performed as per the method specified by the supplier and the purchaser.
4.2 Size deviation
The size deviation of the ingot shall be carried out as per the method specified in YS/T 627 or YS/T 695.
4.3 Macrostructure
The macrostructure test of the ingot shall be carried out as per the method specified in GB/T 4297.
4.4 Appearance quality
Generally, the appearance quality shall be visually examined. If necessary, use the grinding method to determine the depth of the surface defects.
4.5 Corrosion performance
The salt spray corrosion performance shall be carried out as per the method specified in GB/T 10125; the test piece shall be degreased and de-rusted before the test. 4.6 Others
Other requirements are determined through the negotiation between the supplier and the purchaser.
5 Inspection Rules
5.1 Inspection and acceptance
5.1.1 The product shall be inspected by the supplier?€?s technical (or quality supervision) department to ensure that the product quality conform to the provisions of this Standard and purchasing list (or contract); and fill in the quality certificate. 5.1.2 The purchaser shall inspect the received products according to the provisions of this Standard. When the inspection result is inconsistent with the provisions of this Standard and ordering list (or contract), it shall be submitted to the supplier in the batch is judged unqualified.
5.5.2 If the size deviation of any ingot is unqualified, then such ingot is judged to be unqualified.
5.5.3 When there are cracks and flux slag in the macrostructure test result, then such batch is judged to be unqualified; the judgment of other inclusions shall be determined through the negotiation between the supplier and the purchaser.
5.5.4 When the appearance quality is unqualified, then judge the single ingot is unqualified; but the supplier is allowed to reprocess to the qualified and deliver then. If the ingot is still unqualified after processing, then judge the single ingot is unqualified. 5.5.5 When the corrosion performance is unqualified, judge such batch unqualified. 6 Marking, Package, Transportation, Storage and
Quality Certificate
6.1 Marking
6.1.1 The end face of each ingot shall be marked with grade, melting time, sequence number and state.
6.1.2 Each bundle of ingots shall be provided with two labels indicating: a) Seal from the supplier?€?s technical supervision department;
b) Product name;
c) Grade;
d) State;
e) Batch number.
6.2 Package, transportation and storage
The packaging method of the ingots shall be agreed by the supplier and the purchaser; and indicated in the contract. The transportation and storage shall be as stipulate din GB/T 32792.
