1/ The sample shall not be stored in an oven, as the test method states. Perform the test twice; the
results shall conform to table II both times.
2/ Use a single 0.45 micron (µm), cellulose membrane filter, and a maximum filtration time of
15 minutes. As a referee method, either FED-STD-791, method 3009, "Solid-Particle
Contamination in Hydraulic Fluids," or FED-STD-791, method 3012, "Determination of Particulate
Matter in Aerospace Hydraulic Fluids," using an automatic particle counter capable of measuring
the limits in table III (see 6.5.3), shall be run.
3/ The test slabs shall be new (within 6 months of manufacture). This is the same material required by
SAE-AMS3217/2.
