Comment (justification):
Overall vibration for in-situ test. The alarm under BV-3 category with RMS is the same for rigidly and flexible mounting. 0.28 in/sec RMS, which is also the BV-4 category alarm for flexible mounting.
Proposed Change:
replace the alarm level on BV-3 flexible mounted from 0.28 in/sec RMS to 0.45 in/sec RMS.

"Weight" is mentioned in 4 places throughout this standard. We mean "mass" in each case.
Proposed Change:
replace "weight" by "mass" 4 times
