Organization: ASTM
Publication Date: 10 September 1999
Status: inactive
Page Count: 4
ICS Code (Iron and steel forgings): 77.140.85
scope:

1. Scope

1.1 This is an acceptance specification for the magnetic particle inspection of forged steel crankshafts having main bearing journals or crankpins 4 in. [200 mm] or larger in diameter.

1.2 There are three classes, with acceptance standards of increasing severity:

1.2.1 Class 1.

1.2.2 Class 2 (originally the sole acceptance standard of Specification A 456).

1.2.3 Class 3 (formerly covered in Supplementary Requirement S1 of Specification A 456-64 (1970)).

1.3 This specification is not intended to cover continuous grain flow crankshafts, however, Test Method A 983/A 983M may be used for this purpose.

NOTE 1--Specification A 668/A 688M is a product specification which may be used for crankshaft forgings.

1.4 The values stated in either inches or SI (metric) units are to be regarded separately as the standard. Within the text and figures, 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.

1.5 Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inch units.
