7.2 It is realized that the foundry may be unable to perform
the hydrostatic test prior to shipment, or that the purchaser may
wish to defer testing until additional work has been performed
on the casting. In such cases, the foundry is responsible for the
satisfactory performance of the casting when it is tested.
8. Quality
8.1 The surface of the casting shall be examined visually
and shall be free from cracks and hot tears. Other surface
defects shall be judged in accordance with visual acceptance
criteria which may be specified in the order.
9. Rework and Retreatment
9.1 Defects as defined in Section 8 shall be removed and
their removal verified by visual inspection of the resultant
cavities. Defects which are located by inspecting with Supplementary
Requirement S6 or S7, or both, shall be removed or
reduced to an acceptable size.
9.2 If removal of the defect does not infringe upon the
minimum wall thickness, the depression may be blended
uniformly into the surrounding surface.
9.3 If the cavity resulting from defect removal infringes
upon the minimum wall thickness, weld repair is permitted
subject to the purchasers approval. The composition of the
weld rod used shall be suitable for the composition of the metal
being welded.
9.3.1 Only operators and procedures qualified in accordance
with ASME Boiler and Pressure Vessel Code, Section IX, shall
be used. All repair welds will be inspected to the same quality
standards used to inspect the casting.
9.4 Postweld heat-treatment of the repaired casting is neither
required nor prohibited.
10. Permissible Variations in Dimensions
10.1 ThicknessThe wall thickness shall not vary over that
specified by more than 18 in. 3 mm. There shall be no
variation under the specified wall thickness.

to the applicable requirements of the current edition of
Specification A999/A999M, unless otherwise provided herein.
12. Rejection
12.1 Each length of pipe received from the manufacturer

requirements of the specification based on the inspection and
test method as outlined in the specification, the pipe may be
rejected and the manufacturer shall be notified. Disposition of
rejected pipe shall be a matter of agreement between the
manufacturer and the purchaser.
