4.3.1.1 Submission of product. The product shall be submitted in accordance with ANSI/ASQ Z1.4.
4.3.1.2 Size of lot. A lot shall consist of an identifiable group of metal parts assemblies consisting of
components produced by a homogeneous process.
4.3.2 Examination. One hundred percent examination shall be performed for all critical defects.
Examination for major and minor defects shall be performed on a defect basis in accordance with the
classification of defects contained herein, using the sampling plans and associated criteria in Tables II and
III. For an individual defect (single characteristic), the criteria in Table II shall be used. For total defects
within a major or minor group the criteria in Table III shall be used. All non-conforming material shall be
rejected. Inspection for rubber O-rings shall be in accordance with MIL-STD-413. The surface roughness
comparison specimens prescribed in ASME B46.1-2002 shall be used as a basis of comparison for surface
roughness determination. Four power (4×) magnification may be used in performing visual examination
for such defects as burr and foreign matter.
