Use & Relationship

The CS116 Test Plan applies to both parts of military standard MIL-STD-188-125, High-Altitude Electromagnetic Pulse (HEMP) Protection for Ground-Based Facilities Performing Critical, Time-Urgent Missions. This DID applies to fixed facilities in accordance with Part I (MIL-STD-188-125-1A) and to transportable systems in accordance with Part II (MIL-STD-188-125-2). This DID contains the format, content, and intended-use information for the data deliverable resulting from the conducted immunity CS116 test tasks described in section 5.8.1 of each part of MIL-STD-188-125, as applicable.

The purpose of CS116 testing the first article of every MCS installed outside the HEMP-protection subsystem's (HPS') low-risk electromagnetic barrier is to help ensure that the MCS, and any associated special protective measures (SPMs) will provide sufficient hardness to HEMP's conducted-threat environment. The CS116 test procedures, as codified by MIL-STD-461, provide some of the baseline information for assuring that the given MCS, with any SPMs, is adequate to pass HEMP-verification testing.

The CS116 Test Plan describes the methods of test-execution, data-recording, analysis, inspection, and reporting to be used by the contractor to assess and document the results of the MCS' performance. For each individual MCS to be immunity tested per MIL-STD-461 CS116, an individual test plan shall be prepared. The plan provides the means for the Government to understand and duplicate methods used by the contractor to demonstrate the MCS' HEMP-protection performance with respect to MIL-STD-461's pass and fail requirements and MIL-STD-188-125's CS116-test requirements.

If the MCS has already been CS116 tested within seven years prior to its installation at the facility or with the system, then documentation of those previous tests, including plans, reports, and test data, is attached as an appendix.

Preparation Instructions

1Reference documents.The applicable issue of the documents cited herein, including their approval dates and any applicable amendments, notices, and revisions, shall be as specified in the contract. The CS116 Test Plan's classification shall be in accordance with any relevant facility- or system-specific classification guides and also the Defense Threat Reduction Agency (DTRA) Security Classification Guide for DoD Electromagnetic Pulse (EMP) Programs and Activities. (DTRA's security classification guide is available by mail request to ATTN: RD-NTSA, Dr. William Linzey, PhD, Defense Threat Reduction Agency, 8725 John J. Kingman Road, MSC 6201, Fort Belvoir, VA 22060-6201.)

2Format.Contractor format is acceptable.

3Content.The CS116 Test Plan shall document the test-execution, data-recording, analysis, inspection, and reporting procedures to be used by the contractor to perform the CS116 testing on MCS in accordance with MIL-STD-461 and MIL-STD-188-125.
