INSPECT
To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical characteristics
with established standards through examination (e.g., by sight, sound, or feel). This includes scheduled inspection
and gaugings and evaluation of cannon tubes.
TEST
To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteristics of an item
and comparing those characteristics with prescribed standards on a scheduled basis, e.g., load testing of lift devices
and hydrostatic testing of pressure hoses.
SERVICE
Operations required periodically to keep an item in proper operating condition; e.g., to clean (includes decontaminate,
when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical fluids, or gases. This includes
scheduled exercising and purging of recoil mechanisms. The following are examples of service functions:
UNPACK
To remove from packing box for service or when required for the performance of maintenance operations.
REPACK
To return item to packing box after service and other maintenance operations.
CLEAN
TOUCH UP
To spot paint scratched or blistered surfaces.
MARK
To restore obliterated identification.
ADJUST
To maintain or regulate, within prescribed limits, by bringing into proper position, or by setting the operating
characteristics to specified parameters.
ALIGN
To adjust specified variable elements of an item to bring about optimum or desired performance.
CALIBRATE
To determine and cause corrections to be made or to be adjusted on instruments of test, measuring, and diagnostic
equipment used in precision measurement. Consists of comparisons of two instruments, one of which is a certified
standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being compared.
