Yim theem ntawm ballistics resistant iav

Bullet resistant iav yog tsim los nres projectiles tsis tawg, absorbing lawv lub zog thiab khaws cov mos txwv. Txawm hais tias lub khob ua tiav hauv kev nyab xeeb ntawm cov mos txwv los yog tsis yog nyob ntawm ntau yam, xws li: cov khoom siv thiab cov qauv ntawm cov iav; qhov hnyav ntawm lub zog cuam tshuam thiab cov khoom siv hluav taws xob; thiab tus naj npawb ntawm cov kev cuam tshuam tom qab. Kev lees paub qhov kev tiv thaiv qib tshwj xeeb yuav tsum muaj cov txheej txheem kev sim uas tuaj yeem sib koom ua ke ntawm txhua yam ntawm cov dynamic.

Yog li, yuav ua li cas cov mos txwv resistant iav kuaj thiab ntsuas? Hauv cov ntawv blog no, Armortex qhia txog UL rating system thiab qhia txog qee qhov kev ntsuas qib hauv kev nthuav dav.

UL Rating System yog dab tsi?

UL rating system yog ib qho kev ntsuam xyuas tsim los ntawm Underwriter's Laboratory (UL), ib lub koom haum tsis muaj txiaj ntsig tau tsom mus rau kev txhim kho pej xeem kev nyab xeeb los ntawm kev tsim cov txheej txheem rau ntau yam khoom. Lub koom haum no tau tsim cov txheej txheem kev lees paub zoo tshaj plaws rau cov iav tsis muaj phom sij thiab yog ib qho ntawm ob peb Lub Tebchaws Kev Tshawb Fawb Kev Tshawb Fawb tau tso cai los ua kev ntsuam xyuas kev nyab xeeb los ntawm Occupational Safety and Health Administration (OSHA).

Yim qhov sib txawv ntawm cov iav resistant iav tau tsim los ntawm UL, txhua tus muaj peev xwm tiv thaiv kev ruaj ntseg ntawm ntau qhov sib txawv. Ib qho kev piav qhia luv luv ntawm txhua qib hauv qab no:

• Theem 1: Hais txog cov mos txwv iav iav tuaj yeem tiv taus hluav taws los ntawm cov phom me me. Nws yuav tsum muaj peev xwm tiv taus qhov tsawg kawg ntawm peb 9 hli FMJs mus ncig ntawm qhov tsawg kawg nkaus ntawm 1,175 ko taw ib ob (f / s)
• Theem 2: Txhais cov mos txwv resistant iav tsim los tiv thaiv hluav taws los ntawm cov phom loj loj. Nws yuav tsum tiv taus yam tsawg kawg peb txhaj tshuaj ntawm .357 magnum mos ntsiab lus taug kev ntawm qhov nrawm ntawm 1,250f / s.
• Theem 3: Hais txog cov mos txwv iav uas tuaj yeem tiv taus qhov tsawg kawg ntawm peb qhov kev txhaj tshuaj ntawm .44 magnum rounds ntawm qhov nrawm ntawm 1350f / s.
• Qib 4: Sawv cev nce qib hauv cov ntsiab lus ntawm kev tiv thaiv ballistics. Nws txhais cov iav tiv thaiv cov mos txwv uas tuaj yeem tiv taus tsawg kawg ib qho kev txhaj tshuaj los ntawm .30 caliber phom nrog qhov nrawm ntawm 2540f / s.
• Theem 5: Npog cov iav mos mos uas tsim los tiv thaiv tsawg kawg yog ib rab phom 7.62mm FMJ nrog qhov nrawm ntawm tsawg kawg 2750f / s.
• Theem 6: Nws yog ib qho kev txhim kho ncaj qha rau Qib 1, tsim los tiv thaiv tsawg kawg tsib 9 hli puag ncig ncig ntawm qhov siab tshaj qhov siab tshaj plaws ntawm 1400f / s.
• Theem 7: Txhais cov mos txwv resistant iav tsim los tiv thaiv ntau yam hits nrog 5.56 phom FMJs nrog qhov ceev tshaj plaws ntawm 3080f / s.
• Qib 8: Tsim cov qib siab tshaj plaws ntawm kev tiv thaiv muaj nyob rau hauv cov mos txwv iav iav. Cov qib no raug sim los tiv thaiv tsawg kawg tsib txhaj tshuaj los ntawm rab phom 7.62 hli.

Cov qib ballistics no feem ntau muab ua ke ua ke rau cov ntawv thov sib txawv. Qib 1 ballistic resistant iav yog qhov haum tshaj plaws rau cov lag luam me uas nws qhov kev siv tseem ceeb yog kev ua txhaum cai. Qib 2 zoo ib yam siv rau hauv cov neeg siv khoom tab sis feem ntau raug xaiv rau cov tsev uas muaj kev hem thawj loj dua xws li tsev txhab nyiaj thiab jewelers.

Qib 3 cov mos txwv tiv thaiv iav yog nyiam rau cov chaw loj dua qhov kev hem thawj feem ntau hnyav dua. Tub ceev xwm chaw nres tsheb thiab tsoomfwv cov chaw ua haujlwm niaj hnub siv UL Qib 3 cov khoom lag luam ntsuas, txawm hais tias lawv tseem tab tom tau txais kev pom zoo los ntawm qhov ntsuas rau kev ruaj ntseg hauv tsev kawm ntawv.

Qib 4 ntxiv rau muaj kev sib piv ntawm kev tiv thaiv thiab tsim los tiv thaiv hluav taws los ntawm kev ua phem phom sij thiab riam phom tsis siv neeg. Cov no yog siv nyob rau hauv daim ntawv thov kev pheej hmoo siab tshaj plaws uas cov nqi ntxiv ntawm cov khoom siv tau raug lees paub los ntawm qib kev hem thawj. Cov tub rog hauv paus thiab tsoomfwv cov tsev feem ntau siv cov khoom ntsuas UL Qib 4-8.
