Overview
Title:
Hardness Maintenance (HM) and Hardness Surveillance (HS) Plan
Scope:
The Hardness Maintenance (HM) and Hardness Surveillance (HS) 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 HM/HS tasks described in section 4.5 of each part of MIL-STD-188-125, as applicable. The purpose of the HM/HS program is to ensure that the HEMP-protection subsystem’s (HPS’) hardness levels are preserved throughout the service life of the facility or system. HM/HS procedures comprise the preventive maintenance, inspection, test, and repair activities accomplished on a HEMP protected operational facility or system.
