2.11.2.1 All media shall be tested for contamination per
Paragraph 2.11.3.
2.11.3 Operational Parameters for Metallic Sur-
faces. All PMB operations on metallic surfaces shall
conform to the following parameters:
2.11.3.1 Pressure shall be within the range of 40 to 60 PSI
at the blast nozzle for 3.0 MOH hardness media (Type I), 25
to 40 PSI at the nozzle for 3.2 MOH hardness media (Type
V), and 20 to 30 PSI at the nozzle for 3.5 MOH hardness
media (Type II). See Paragraph 2.11.1 for recommended
parameters for stripping AGE and vehicles.
2.11.3.2 The blast nozzle tip to work surface standoff
distance shall be within the range of 12 to 24 inches for 3.0
MOH hardness media (Type I), 12 to 24 inches for 3.2 MOH
hardness media (Type V), and 18 to 30 inches for 3.5 MOH
hardness media (Type II). See Paragraph 2.11.1 for recom-
mended parameters for SE and vehicles.
2.11.3.3 The angle of incidence between the blast nozzle
and the work surface shall be within the range of 30 to 90
degrees for 3.0 MOH hardness media (Type I), 30 to 90
degrees for 3.2 MOH hardness media (Type V), and 0 to 60
degrees for 3.5 MOH hardness media (Type II). SE and
vehicles may be stripped at any angle.
2.11.4 Usage Restrictions. PMB shall not be used on
metal structures having a thickness less than 0.016 inch for
3.0 MOH and 3.2 MOH hardness media (Type I and V) and
0.032 inch for 3.5 MOH hardness media. See Paragraph
2.11.1 for portions pertaining to SE and vehicles.
NOTE
When blasting close to masking on the work
surface, the nozzle shall be held as close as
possible to 90 degrees with the work surface to
prevent undercutting of the masking materials.
2.11.5 Operational Parameters for Non-Metallic
(Composite) Surfaces. All PMB operations on non-
metallic surfaces (fiberglass, kevlar/epoxy, graphite/epoxy,
boron/epoxy, etc.) shall conform to the following parameters:
2.11.5.1 Pressure shall be within the range of 30 to 60 PSI
at the blast nozzle for the 3.0 MOH hardness media (Type I)
and 25 to 40 PSI for the 3.5 MOH hardness media (Type II)
and the 3.2 MOH hardness media (Type V).
2.11.5.2 The blast nozzle tip to work surface standoff
distance shall be within the range of 12 to 24 inches.
2.11.5.3 The angle of incidence between the blast nozzle
and the work surface shall be within the range of 40 to 60
degrees.
