The M1114 HMMWV Interim Fragment (Frag) Kit 5 was an add-on armor for doors of the M1114 HMMWV.It consisted of four bolt-on doors that provided another layer of metal over the previously established factory-built armor, and was initially deployed in the field in April 2006.
Magnetic particle inspection (MPI) is a nondestructive testing process where a magnetic field is used for detecting surface, and shallow subsurface, discontinuities in ferromagnetic materials. Examples of ferromagnetic materials include iron , nickel , cobalt , and some of their alloys .
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
In this technique, permeability variations are suppressed by applying a magnetic field. The saturation probes contain conventional eddy current coils and magnets. This inspection is used on partially ferromagnetic materials such as nickel alloys, duplex alloys, and thin-ferromagnetic materials such as ferritic chromium molybdenum stainless steel.
Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and is used widely in a variety of industries.
Utilizing a breaching tool is unnecessary if the door is unlocked and easy to open. [5] [3] [6] [1] If the door is locked, breachers can attempt to force inward-opening doors with a strong kick. The breacher will aim to hit the door near the locking mechanism, but not kick the doorknob itself as one can easily twist an ankle doing so. [7]
A slim jim (more technically known as a lockout tool) is a thin strip of metal (usually spring steel) roughly 60 centimetres (24 in) long and about 2–4 centimetres (0.79–1.57 in) wide originally marketed under that name by HPC Inc., a manufacturer and supplier of specialty locksmithing tools.
A metal doorframe with a strike plate built in: in other doors this would be a metal strikeplate in a wooden doorframe. The term door security or door security gate may refer to any of a range of measures used to strengthen doors against door breaching, ram-raiding and lock picking, and prevent crimes such as burglary and home invasions.
