4.2 Sampling. Samples from bulk or packaged lots (see 6.8), shall be taken for testing in
accordance with ASTM D4057 or D4177, as appropriate.
4.3 Verification methods. The types of verification methods included in this section are
visual inspection, measurement, sample tests, full-scale demonstration tests, simulation,
modeling, engineering evaluation, component properties analysis, and similarity to previously
approved or previous qualified designs.
4.3.1 Verification alternatives. The manufacturer may propose alternative test methods,
techniques, or equipment, including the application of statistical process control, tool control, or
cost effective sampling procedures, to verify performance. See the contract for alternatives that
replace verification required by this specification.
4.3.2 Inspection conditions. Tests may be conducted, in any sequence, in any plant or
laboratory approved by the qualifying activity (see 6.2 and 6.4).
4.3.3 Operating requirements verification. Complete each test under 4.3.3.
4.3.3.1 Finished oil property verifications. Use the test methods as specified in table III
to determine that finished oil properties are as specified.
