Lesson 2/Learning Event 3
Physical property tests are analytical tests used to detect property changes
in used oil.
For example, changes in viscosity, fuel dilution, or water
content may be indicative of faulty equipment, operating conditions, or
A resample is a sample, specifically requested by the laboratory, of the
same oil taken under the same conditions as the previous sample. Selected
equipment/components are those enrolled in the AOAP.
Unit commanders will--
Implement local AOAP policies and procedures within their unit.
Ensure that all AOAP-designated equipment is enrolled in the program
and that samples are submitted at prescribed intervals.
Ensure that oil changes conform to warranty requirements.
Ensure that laboratory recommendations are complied with immediately.
Ensure that unit personnel are trained in AOAP procedures.
Appoint a unit AOAP monitor.
Only the equipment/components listed in the appendices of TB 43-0210 or
other equipment/components authorized by the PM AOAP will be sampled.
Routine samples are to be submitted at prescribed intervals as established
in the appropriate appendix of TB 43-0210. (See Figure 14 for an example.)
Sampling intervals are not the same for all items of equipment.
should be taken as near the prescribed interval as possible. Sampling at
the prescribed time is not always possible. In such instances, a 10-percent
variance before or after the scheduled date, hours, or miles for sampling is
