Vim li cas lub tsho tiv thaiv mos txwv tsis muaj pov thawj?
Nov yog ib lo lus nug uas peb tau nug ntau zaus.Lub tsho tiv thaiv mos txwv yog raws li lub hauv paus tsim los nres cov mos txwv, thiab tsis yog rab phom los yog cov twj paj nruag.Rau lub tsho tiv thaiv mos txwv los ua pov thawj zoo ib yam, nws yuav tsum muaj peev xwm nres qhov qis tshaj plaws stab resistant qib, uas rau ob qho tib si HOSDB thiab NIJ yog 24 (E1) / 36 (E2) joules los ntawm ib tug engineered hniav.

Ib lub tsho tiv thaiv cov mos txwv ib txwm uas tsim los kom nres cov mos txwv yuav tuaj yeem nres 5-10 joules nyob ntawm seb cov khoom siv li cas.Qhov no yog 1/3 ntawm lub siab xav tau lub tsho pov thawj pov thawj yuav tsum tau nres.

Ib lub tsho pov thawj pov thawj yuav xub ua pov thawj thaum nws tuaj yeem tso tseg qhov tsawg kawg nkaus uas yuav tsum tau muaj rau lub tsho pov thawj pov thawj raws li NIJ 0115.00 thiab HOSDB qhov twg qib qis tshaj ntawm kev tiv thaiv yog qib 1.

Txhua yam hauv qab qib 1 (qis dua 36 joules) yuav yooj yim nkag mus rau qhov nws muaj peev xwm nkag mus rau qib 1 stab pov thawj tsho khuam nrog ib qho nyuaj stab.

BFS / BFD yog dab tsi?(Pab ntsej muag kos npe / Rov qab lub ntsej muag deformation)
Rov qab lub ntsej muag Kos Npe / Deformation yog qhov tob rau hauv "lub cev" thaum lub mos txwv tsoo lub tsho tiv thaiv mos txwv.Rau cov mos txwv pov thawj tsho khuam raws li NIJ tus qauv 0101.06, qhov tob ntawm cov mos txwv yuav tsum tsawg dua 44 hli.Raws li HOSDB thiab German Schutzklasse Standard Edition 2008, qhov tob tsis tuaj yeem tshaj 25 hli rau HOSDB.

Back face signature thiab Back face deformation yog cov ntsiab lus siv los piav txog qhov tob ntawm qhov cuam tshuam ntawm cov mos txwv.

Cov tsho tiv thaiv cov mos txwv ua raws li NIJ tus qauv yog ua kom tsis txhob muaj .44 Magnum, uas yog ib qho ntawm lub ntiaj teb cov caj npab loj tshaj plaws.Qhov no kuj txhais tau hais tias lub cev armor tsim rau American NIJ tus qauv yuav hnyav dua li cov vests tsim rau German SK1 tus qauv.

Dab tsi yog Blunt Force Trauma
Blunt force trauma lossis blunt trauma yog qhov kev puas tsuaj rau koj lub cev hauv nruab nrog cev yuav muaj kev cuam tshuam rau cov mos txwv.Qhov siab tshaj plaws ntawm qhov yuav tsum yog tsawg dua 44 mm.Raws li NIJ tus qauv 0101.06.Nyob rau tib lub sijhawm, lo lus tseem siv tau hais txog Lub Cev armor uas muab lub zog zoo rau kev raug mob tawm tsam cov batons, baseball puav thiab cov khoom siv dag zog zoo sib xws uas cov tsho pov thawj stab ntau dua los ua kom tsis muaj zog ntawm cov khoom ntaus.
