NOTE The manufacturing process covers all operations up to the delivery of the product.
7 Chemical composition
The chemical composition of cast unalloyed magnesium shall conform to the requirements for the appropriate material given in Table 1.
Unless otherwise specified in the enquiry and order, the chemical composition of the cast unalloyed magnesium shall relate to that of samples taken from the melt at the time of pouring.
8 General condition of the product
The product shall have a clean surface in accordance with the agreement between the manufacturer and the purchaser, and shall be free from visible and internal defects to a level also agreed between the manufacturer and the purchaser.
9 Testing conditions

10 Testing
Analysis to ensure conformity with the chemical composition requirements given in Table 1 shall be carried out on samples taken by the manufacturer and representative of the material delivered. Test method of analysis shall be subject to an agreement between the manufacturer and the purchaser.
11 Rounding of results
In recording the results of the chemical analysis, the result obtained for any property specified in this document shall be expressed to the same number of decimal places as the corresponding value in this document. Rounding shall be carried out as specified in ISO 80000-1:2009, B.2 and B.3.
