MIL-PRF-83756D
discharging a constant, evenly distributed stream of media on a material surface having a minimum curvature of
12 inch radius and reclaim, clean and recycle the blasting media during the operation. When blasting at 80 pounds
per square inch gage with size 13 glass beads, the machine shall produce a cleaned path not less than 1 inch wide
at a rate of 1 lineal foot in 10 seconds. When blasting at 80 pounds per square inch gage with 26 grit aluminum
oxide, the unit shall produce a cleaned path not less than 1 inch wide at a rate of 4 lineal feet in 10 seconds.
3.3.2.2 Design requirements. The Type II unit shall be equipped with a cyclone type reclaim system that separates
reusable abrasive from the spend abrasive returned from the workpiece by the recovery system. The reclaimed
abrasive shall be returned to the abrasive hopper. The hopper shall have a capacity of not less than 5 pounds of
size 3 glass beads, have provisions for draining the beads and all components shall be accessible for repair. The
unit shall be provided with a blast gun and 20 feet of hose assembly. The blast machine shall be mounted on
industrial type casters to afford maneuverability by one man. The unit shall be provided with an air pressure
regulator with gage, moisture separator, instructional panel, brushes and storage compartment.
3.3.1 Power output. The unit shall be operable from a 110/220 volt, single phase, 60 Hz power outlet.
3.3.2 Finish and painting. The machine shall be finished and painted in accordance with MIL-HDBK-808,
F-100. The Type I cabinet interior shall be white, color number 37886, and the exterior shall be gray, color
number 16473 of FED-STD-595. The Type II machine shall be gray color number 16473 of FED-STD-595.
3.4 Ownership and support requirements. The unit shall meet the following logistics requirements.
3.4.1 Reliability. Achieve at least 6000 hours mean time between failure (MTBF).
3.4.2 Safety. Protect personnel from the blast operations with no detected emissions from the blast operations.
3.4.3 Maintainability. Provide easy access to components requiring routine or frequent maintenance or
adjustment. The units shall require no additional lubrication or preventive maintenance during its normal service
life.
3.4 Interface requirements.
3.5 Ownership and support requirements verification. The unit shall meet the following logistics requirements.
3.5.1 Reliability. The unit shall be capable of 6,000 hours between failures (MTBF). Reliability calculations shall
be based on the total amount of hours operated without failure divided by the number of times the unit is unable to
perform as required in this specification.
3.5.2 Safety. The unit shall be inspected for hazardous burrs, nicks, sharp edges, foreign materials, or other
imperfections that pose physical danger to an installer/operator. Inspect the unit for exposed, frayed, unsecured, or
otherwise improperly protected circuits that pose electrical danger to an installer/operator.
3.5.3 Maintainability. Upon completion of reliability evaluation, verify that the unit does not require preventative
maintenance such as lubrication, cleaning or adjustment. Demonstrate or prove other evidence that key design and
assembly characteristics contribute to the ease of maintenance and prevention of common mishandling,
reassembly, or reconnection errors.
3.6 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally
preferable materials should be used to the maximum extent possible provided that the material meets or exceeds
the operational and maintenance requirements, and promotes economically advantageous life cycle cost.
