    ASTM A47 / A47M

    1. Scope

    1.1 This specification covers ferritic malleable castings for general engineering usage at temperatures from normal ambient to approximately 400°C (750°F).

    1.2 No precise quantitative relationship can be stated between the properties of the iron in various locations of the same casting and those of a test specimen cast from the same iron (see Appendix X1).

    1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
