Tes ua lub luag haujlwm tseem ceeb hauv cov txheej txheem ua haujlwm ntau lawm. Txawm li cas los xij, ob txhais tes kuj yog qhov chaw uas raug mob yooj yim, suav txog li 25% ntawm tag nrho cov neeg raug mob. Hluav taws kub, kub kub, hluav taws xob, tshuaj lom neeg, cuam tshuam, txiav, abrasions, thiab kab mob tuaj yeem ua rau muaj mob rau tes. Kev raug mob txhua yam xws li kev cuam tshuam thiab kev txiav yog ntau dua, tab sis kev raug mob hluav taws xob thiab hluav taws xob raug mob hnyav dua thiab tuaj yeem ua rau muaj kev tsis taus lossis tuag taus. Txhawm rau tiv thaiv cov neeg ua haujlwm txhais tes los ntawm kev raug mob thaum ua haujlwm, lub luag haujlwm ntawm cov hnab looj tes tiv thaiv yog qhov tseem ceeb tshwj xeeb.
Cov hnab looj tes tiv thaiv kev soj ntsuam cov qauv siv
Thaum Lub Peb Hlis 2020, European Union tau tshaj tawm tus qauv tshiab:TS EN ISO 21420: 2019Cov kev cai dav dav thiab cov qauv kev sim rau cov hnab looj tes tiv thaiv. Cov neeg tsim cov hnab looj tes tiv thaiv yuav tsum xyuas kom meej tias cov khoom siv los tsim lawv cov khoom tsis cuam tshuam rau kev noj qab haus huv ntawm cov neeg ua haujlwm. EN ISO 21420 tus qauv tshiab hloov EN 420 tus qauv. Tsis tas li ntawd, EN 388 yog ib qho ntawm cov qauv European rau cov hnab looj tes tiv thaiv kev lag luam. European Committee for Standardization (CEN) pom zoo version EN388: 2003 thaum Lub Xya Hli 2, 2003. EN388: 2016 tau tshaj tawm thaum lub Kaum Ib Hlis 2016, hloov EN388: 2003, thiab cov ntawv ntxiv EN388: 2016 + A1: 2018 tau kho dua tshiab hauv 2018.
Muaj feem xyuam rau cov hnab looj tes tiv thaiv:
TS EN 388: 2016 Cov qauv siv tshuab rau cov hnab looj tes tiv thaiv
TS EN ISO 21420: 2019 Cov kev cai dav dav thiab cov qauv kev sim rau cov hnab looj tes tiv thaiv
EN 407 Txuj rau cov hnab looj tes tiv thaiv hluav taws thiab kub

Cov hnab looj tes tiv thaivkev tshuaj xyuas
Txhawm rau tiv thaiv cov neeg siv khoom muaj kev nyab xeeb thiab zam kev poob rau cov neeg muag khoom los ntawm kev rov qab los ntawm cov khoom lag luam teeb meem zoo, tag nrho cov hnab looj tes tiv thaiv xa tawm mus rau EU lub teb chaws yuav tsum dhau cov kev tshuaj xyuas hauv qab no:
1. On-site mechanical performance testing

TDM txiav xeem siv cov hniav los txiav cov hnab looj tes xibtes ntawm qhov ceev tsis tu ncua. Nws kuaj qhov ntev taug kev ntawm cov hniav thaum nws txiav los ntawm cov qauv hauv cov khoom sib txawv. Nws siv cov qauv lej kom suav nrog (txoj kab nqes) kom tau txais cov nqi zog uas yuav tsum tau siv los ua kom cov hniav mus txog 20mm. Txiav tus qauv dhau los.
Qhov kev sim no yog ib yam khoom tshiab tau ntxiv hauv EN388: 2016 version. Qhov tshwm sim theem yog qhia raws li AF, thiab F yog qib siab tshaj. Piv nrog EN 388: 2003 coupe xeem, TDM xeem tuaj yeem muab cov ntsuas kev ua haujlwm raug txiav ua haujlwm ntau dua.
5.6 Kev cuam tshuam tsis zoo (EN 13594)
Lub cim thib rau sawv cev rau kev tiv thaiv kev tiv thaiv, uas yog qhov kev xaiv xaiv. Yog tias cov hnab looj tes raug sim rau kev tiv thaiv kev cuam tshuam, cov ntaub ntawv no tau muab los ntawm tsab ntawv P ua lub cim thib rau thiab zaum kawg. Yog tsis muaj P, hnab looj tes tsis muaj kev tiv thaiv.
2. Kev tshuaj xyuas qhov tshwm simntawm cov hnab looj tes tiv thaiv
-Cov neeg tsim khoom npe
- Hnab looj tes thiab qhov ntau thiab tsawg
- CE daim ntawv pov thawj
- EN standard logo daim duab
Cov cim no yuav tsum tau ua kom pom tseeb thoob plaws hauv lub neej ntawm hnab looj tes
3. Cov hnab looj tes tiv thaivntim tshuaj xyuas

- Lub npe thiab chaw nyob ntawm lub cev ntawv pov thawj uas tau lees paub cov khoom
- Cov qauv yooj yim
5. Yuav tsum muaj kev phom sijntawm cov hnab looj tes tiv thaiv
- Cov hnab looj tes yuav tsum muaj kev tiv thaiv siab tshaj plaws;
- Yog tias muaj cov seams ntawm lub hnab looj tes, kev ua haujlwm ntawm cov hnab looj tes yuav tsum tsis txhob txo qis;
- pH tus nqi yuav tsum nyob nruab nrab ntawm 3.5 thiab 9.5;
- Chromium (VI) cov ntsiab lus yuav tsum qis dua qhov ntsuas tus nqi (<3ppm);
- Cov hnab looj tes roj hmab ntuj yuav tsum tau sim ntawm cov proteins uas tau muab tshem tawm kom ntseeg tau tias lawv tsis ua rau muaj kev tsis haum rau tus neeg hnav;
- Yog tias tau muab cov lus qhia tu, cov qib kev ua haujlwm yuav tsum tsis txhob txo qis txawm tias tom qab ntxuav ntau tshaj plaws.
EN 388: 2016 tus qauv tuaj yeem pab cov neeg ua haujlwm txiav txim siab seb lub hnab looj tes twg muaj qhov tsim nyog ntawm kev tiv thaiv kev pheej hmoo ntawm kev ua haujlwm hauv chaw ua haujlwm. Piv txwv li, cov neeg ua haujlwm tsim kho feem ntau yuav ntsib kev pheej hmoo ntawm kev hnav thiab tsim kua muag thiab yuav tsum xaiv cov hnab looj tes nrog kev hnav siab dua, thaum cov neeg ua haujlwm hlau yuav tsum tau tiv thaiv lawv tus kheej los ntawm kev raug mob los ntawm kev txiav cov cuab yeej lossis khawb los ntawm cov npoo hlau ntse, uas yuav tsum tau xaiv cov hnab looj tes nrog. qib siab ntawm kev txiav tsis kam. Hnab looj tes.
