4.6
Examination.
4.6.1 Visual. Each forging shall be carefully examined to determine compliance
with the identification marking (see 3.7) and workmanship (see 3.9) requirements.
4.6.2 Dimensional. For each acceptance lot, representative forgings shall be
selected in accordance with table III and examined to determine compliance with
requirements of 3.6.

4.6.3 Preparation for shipment. Prior to shipment, examination shall be made to
determine compliance with section 5.
4.7
Test specimens.
4.7.1 Rejection. Unless otherwise specified (see 6.2) where one or more test
specimens fail to meet the requirements of the specification the lot represented
by the specimen or specimens shall be subject to rejection.
4.7.2 Retest. When no sampling plan is provided or approved by the procuring
agency (see 6.2) and where there is evidence that indicates that the specimen was
not representative of the lot of material, and when the detail specification does
not otherwise specify, at least two specimens shall be selected to replace each
test specimen which failed. All specimens so selected for retest shall meet the
requirements of the specification or the lot shall be subject to rejection.
4.7.3 Chemical composition. Samples for chemical analysis shall be prepared in
accordance to test methods specified in ASTM E34 or ASTM E716.
4.7.4 Mechanical properties. Tension test specimens shall conform to the
dimensions of the standard 0.500 inch round specimen (figure 8) of ASTM B557. If
the forging dimensions prevent the use of the standard 0.500 inch round specimen,
the largest of the subsize proportional specimens shown in figure 8 of ASTM B557,
which can be obtained, shall be used. Longitudinal tension test specimens shall
be taken with the long axis parallel to the direction of maximum metal flow.
Transverse specimens shall be taken with the long axis perpendicular to the
direction of maximum metal flow. Actual location shall be as specified on the
drawing or in the contract or order (see 6.2).
4.8
Test procedures.
4.8.1 Chemical composition. Chemical analysis shall be conducted in accordance
with one or more of ASTM E34, E227, E607, E716, and E1251.
4.8.2 Mechanical properties.
The mechanical properties shall be determined in
accordance with ASTM B557.
