Use & Relationship
The HEMP Protection Subsystem (HPS) Performance Electromagnetic (EM) Barrier Test Report applies to MIL-STD-3023A, High-Altitude Electromagnetic Pulse (HEMP) Protection for Military Aircraft. DI-EMCS-81852, HEMP Protection Subsystem Performance Test Report, is hereby cancelled and superseded by DI-EMCS-81852A. This data item description (DID) contains the format, content, and intended-use information for the data deliverable resulting from the HPS test tasks described in Appendix C, sections C.4.8 and C.4.9, of MIL-STD-3023A, as applicable.
The HEMP Protection Subsystem (HPS) Performance Electromagnetic (EM) Barrier Test Report describes the tests, analyses, and inspections used by the contractor and documents the results, verifying compliance with the HEMP interface and performance requirements of an aircraft during the engineering development phase. The report provides the means for the Government to evaluate HEMP protection performance results.
This DID is related to DI-EMCS-81850A, DI-EMCS-81851A, and DI-EMCS-81854A.
This DID supersedes DI-EMCS-81852.
Preparation Instructions
1Reference documents.The applicable issue of the documents cited herein, including their approval dates and any applicable amendments, notices, or revisions, shall be as specified in the contract. The HEMP Protection Subsystem (HPS) Performance Electromagnetic (EM) Barrier Test Report classification shall be determined using the DTRA Security Classification Guide for DoD Electromagnetic Pulse (EMP) Programs and Activities (U) available by mail request to ATTN: RD-NTSA, Defense Threat Reduction Agency, 8725 John J. Kingman Road, MSC 6201 Fort Belvoir, Virginia 22060-6201 and any relevant system specific classification guides.
2Format.The report shall be in contractor format.
3Content.The report shall describe the overall test results for the Continuous Wave Immersion (CWI) and Pulse Current Injection (PCI) tests for each requirement specified in the contract for the aircraft being developed.
3.1Summary information.This report shall summarize the following:
3.1.1.1System description including any pertinent test issues.
3.1.1.2Statement of any assumptions and limitations associated with CWI or PCI tests.
3.1.2A general description of the results shall be provided for testing of each interface and performance requirement area listed in section 3.2 below.
3.1.2.1Synopsis of CWI and PCI test procedures and references to detailed procedures
3.1.2.2Successes and failures
3.1.2.3Impacts of failures
3.1.2.4Recommendations to resolve failures
3.2Detailed information.For CWI and PCI testing, a single test report shall be prepared. The test report shall contain the following information:
3.2.1Aircraft or equipment identification (including tail number for production aircraft) and a reference to applicable test plans and procedures
3.2.2When and where tests were conducted
3.2.3Who conducted the tests
3.2.4A discussion of any deviations from the test plans or requirements of MIL-STD-3023A, Appendix C
3.2.5Copies of measured test results including all raw and processed test oscillographic waveform test data in engineering units.The electronic data format will be described in the written test report and delivered to the government
3.2.6Summary tables of measured quantities shall be provided including design margin calculations with comparisons to pass/fail criteria based on norm attributes of each oscillographic waveform.(See MIL-STD-3023A, Appendix C for definition of norm attributes)
3.2.7Test chronology including sequence of events; findings from investigations into causes of failures; if any; and corrective actions and retest results
3.3Analysis section.The analysis section shall include post-test analysis of CWI and PCI test data, including calculations of threat responses from CWI and PCI data; analysis of test adequacy; and development of hardness conclusions
3.4Post-test analysis will include development of a corrective plan and, if applicable, the MIL-STD-3023A Hardness Allocation Report (HAR) (DI-EMCS-81850A) will be updated.
