a) the complete designation of the material:
b) any special requirements which have to be agreed between the manufacturer and the purchaser. All agreements between the manufacturer and the purchaser shall be made by the time of acceptance of the order.
6 Manufacture
The method of producing grey cast iron and its chemical composition shall be left to the discretion of the manufacturer, who shall ensure that the requirements of this International Standard are met for the material grade specified in the order.
NOTE For grey cast irons to be used in special applications, the chemical composition and heat treatment may be the subject of an agreement between the manufacturer and the purchaser.
7 Requirements
7.1 Mechanical properties
The order shall specify, in an unambiguous manner, whether the tensile strength measured on separately cast samples, or the Brinell hardness measured on the casting, is the characterizing property. If it does not do so, then the manufacturer shall characterize the material according to tensile strength.
7.2 Tensile properties
7.2.1 Test pieces machined from separately cast samples
The tensile properties of the eight grades of grey cast iron specified by tensile strength, when measured in accordance with 9.1 using test pieces machined from separately cast samples, shall be in accordance with the requirements of Table 1.
The number in position 3 of the designation is the minimum tensile strength of the grade. The maximum tensile strength of the grade is the minimum value plus 100 N/mm2.
7.2.2 Test pieces machined from cast-on samples
The tensile properties of test pieces machined from cast-on samples, for the eight grades of grey cast iron defined by tensile strength, shall be in accordance with the requirements of Table 1.
7.2.3 Test pieces cut from a casting
If applicable, the tensile properties of test pieces cut from a casting, for the eight grades of grey cast iron defined by tensile strength, shall be agreed between the manufacturer and the purchaser, and these tensile properties shall be in accordance with the requirements in the agreement.AS 1830-2007 pdf free download.
