4.3.3.2.3 Porosity and surface finish of mounting base (see 3.4
and dwg. 10048784) - Porosity - Major defect - Code No. 1 1006 ;
Surface Finish - Major defect - Code No. 11007. A sample of 10
mounting bases shall be selected from each lot and tested as specified
in 4.4.3. If two or more mounting bases fail to conform to the
requirements specified, the lot shall be rejected.
4.3.3.2.3.1 Surface finish of graze lever shaft and mounting
base (see dwg. 10048784) - Major defect - Code No. 1008. A sample
of 10 mounting bases shall be selected from each lot and tested
as specified in 4.4.3.1. If one or more mounting bases is classed
defective, the lot shall be rejected.
4.3.3.2.4 Operation of setback assembly (see 3.6); Functioning
during non-functioning test - critical defect - Code No. 14007;
Failure to function within maximum time on functioning time test -
Major defect - Code No. 14008. This test shall be performed 100
percent on base plate and rotor assemblies. The test shall be
performed as specified in 4.4.8 using test equipment specified
in 4.3.4. Defective assemblies shall be rejected and removed
from the lot.

4.3.3.2.5 Functioning of fuze elements (see 3.7) non-functioning,
functioning - Major defect - Code No. 1 4009; Examination for positioning
of locking shaft (see dwg. 9252817) - Major defect - Code No. 14010.
This test and examination shall be performed 100 percent on base plate and rotor
assemblies, less primer, (see dwg. 92528170 by assembling a firing pin,
firing pin spring, and base plug to each assembly. The assembly shall then
be tested as specified in 4.4.7 using test equipment specified in 4.3.4.
Assemblies classed defective may be disassembled and the firing pin
or the firing pin spring or the locking shaft or by combination
thereof may be replaced and retested as often as necessary to obtain
acceptable assemblies. Assemblies which contain locking shafts which
do not bear on the graze level as illustrated on the applicable drawing
shall be classed defective and removed from the lot, subject to
repositioning of the locking shaft and re-examination prior to re-entry
into the lot. The set of graze elements shall be identified so that
subsequent assembly of the graze elements into the proper base plate
and rotor assemblies is assured.

4.3.3.2.6 Rotor arming time at plus 70 degrees Fahrenheit ("F) -
(see 3.8.1) - Arming time, minimum - Critical defect - Code No. 14011;
and Arming time, maximum - Major defect - Code No. 14012.
his test
shall be performed 100 percent on base plate and rotor assemblies
conditioned within the temperature limitations of 65F. and 85F.,
and the assemblies shall comply with the requirements as specified in
paragraph 3.8.1. The test shall be performed as specified in 4.4.9
using test equipment specified in 4.3.4. Assemblies failing to arm in
the time specified shall be classed defective and removed from the lot.
On completion of arming time test visually confirm rotor restored to
unarmed position - Critical defect - Code No. 14017.
