406.1 Purposes.
b. This task pertains mainly to the results of materiel tests performed in environmental laboratories. The ETR provides the acquisition activity with environmental laboratory test data early in the development cycle. The laboratory ETR is appropriate for design evaluation tests, operational worthiness tests, and qualification tests. Data from these laboratory tests serve as early warnings of unanticipated deviations from performance requirements. They support failure analyses and corrective actions related to the ability of materiel items to survive specific environmental conditions. These laboratory test reports (neither singularly nor in aggregate) are not substitutes for reports of development or operational tests conducted in natural field/fleet environments.
406.2 Task description. For each laboratory test conducted, provide the following:
406.2.1 General information.
406.2.1.1 Main body. Include the following in the main body of the report:
b. Functional description of the failed or affected parts of the materiel.
c. Causes of failures, if known.
d. Proposed corrective actions if determinable.
e. Test conditions (quantitative and qualitative data on environmental parameters of test).
406.2.1.2 Attachments. Include the following as attachments:
b. Laboratory failure analysis reports (which identify the physics-of-failure to the extent possible).
c. A list of all other development and production activities where the same part failed, for example:
(2) Reliability tests
(3) Screening tests
(4) Bench checks
(5) Acceptance test procedures
406.2.2 Content requirements.
406.2.2.1 Interim test reporting. Unless otherwise specified, accomplish this reporting by letter.
