Standard Specifications for Lightweight and Thin-Sectioned Gray Iron Castings
|Publication Date:||1 January 1947|
These specifications cover lightweight and thin-sectioned gray iron castings in which appearance, machinability, and dimension tolerances are primary considerations. It is the purpose of these specifications to establish a standud of quality for lightweight and thinsectioned gray iron castings based on the visual inspection of sample castings and testing of representative locations on sample castings for machinability. Strength is not a primary consideration in the castings covered by these specifications, so all reference to classification by strength or to physical tests for strength is intentionally omitted. In those cases where some test is felt necessary to determine serviceability, such test should be made as provided in Section 3.
