4.3 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.
4.3.1 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 methods required by this specification.
4.3.2 Inspection conditions. Unless otherwise specified herein, the filter element shall
meet the performance requirements specified below when installed in an air cleaner housing
conforming to MIL-PRF-62048. The filter element and air cleaner housing is referred to herein as
"air cleaner assembly". The filter element and assembled components are referred to herein as
"filter element assembly". The specific validation equipment for the filter element shall be in
accordance with appendix A. Unless otherwise specified herein, performance requirements shall
be met with a clean, new element (see 6.2) under the following conditions:
a. Ambient temperature - 21.2 to 32.2°C (70 to 90°F).
b. Relative humidity
- 30 to 65 %.
c. Air flow
- The rated airflow shall be as specified in the applicable
contract and variable airflow shall be as specified in
