classified as follows:
a. First article inspection (see 4.1.1).
b. Conformance inspection (see 4.1.2).
4.1.1 First article inspection. First article inspection shall be performed on the first six
assemblies selected from the first ten assemblies produced (or whenever else the contract
specifies) when a first article sample is required (see 3.1). This inspection shall include the
verifications listed in table II.
4.1.2 Conformance inspection. Conformance inspection shall include those
examinations and tests from table II as defined in the contract.
4.2 Verification methods. Acceptable verification methods included in this section are
visual inspection, and measurement, sample tests, full-scale demonstration tests, simulation,
modeling, engineering evaluation, component properties analysis, and similarity to previously
approved or previously qualified designs.
4.2.1 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 methods required by this specification.
