4.3.3 Tests. The sample selected in accordance with 4.3.1.1 shall be subjected to the
tests specified in table I. The acceptance number in all cases is zero.
4.3.4 Laser filter test. Each vision block with a laser filter shall be subjected to the
optical density test specified in table I (see 3.4.2).
4.4 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 previously-qualified designs.
4.4.1 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 (see 6.2) for
alternatives that replace verifications required by this specification.
4.5 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be
conducted under the following conditions:
a. Air temperature: 23±10 °C (73±18 °F)
b. Barometric pressure: 725 (+50/-75) mm [28.5 (+2/-3) in.] mercury (Hg)
c. Relative humidity: 50±30%
