Muaj ntau hom kev txiav cov hnab looj tes tiv thaiv hauv khw. Puas yog qhov zoo ntawm cov hnab looj tes tiv thaiv zoo, qhov twg tsis yooj yim rau hnav, thiab yuav ua li cas xaiv kom tsis txhob muaj kev xaiv tsis raug?
Qee cov hnab looj tes tiv thaiv kev ua lag luam muaj lo lus "CE" luam tawm rau sab nraub qaum. Puas yog "CE" txhais tau tias qee yam ntawv pov thawj ntawm kev ua raws?
Lub cim "CE" yog daim ntawv pov thawj kev nyab xeeb, uas yog suav tias yog daim ntawv hla tebchaws rau cov tuam txhab lag luam qhib thiab nkag mus rau European lag luam. CE txhais tau tias European kev sib koom siab (European Conformity). Keeb kwm CE txhais tau hais tias tus qauv European, yog li dhau ntawm kev ua raws li tus qauv, cov qauv dab tsi yuav tsum tau ua raws li cov hnab looj tes tiv thaiv?
Cov hnab looj tes tiv thaiv kev tiv thaiv kev puas tsuaj feem ntau ua raws li tus qauv EN 388, qhov tseeb version yog 2016 version, thiab American standard ANSI / ISEA 105, qhov tseeb version kuj yog 2016.
Hauv ob qhov kev qhia tshwj xeeb, cov ntaub ntawv qhia rau qib txiav tsis kam yog txawv.
Cov hnab looj tes tiv thaiv tau lees paub los ntawm tus qauv en yuav muaj cov qauv ntaub thaiv npog loj nrog lo lus "EN 388" rau ntawm nws. Muaj 4 lossis 6 tus lej ntawm cov ntaub ntawv thiab cov ntawv Askiv nyob rau hauv daim ntaub thaiv loj heev. Yog tias nws yog 6-tus lej cov ntaub ntawv thiab cov ntawv Askiv, nws qhia tau hais tias EN 388: 2016 specification tshiab yog siv, thiab yog tias nws yog 4-tus lej, nws qhia tau hais tias qhov qub 2003 specification yog siv.
Lub ntsiab lus ntawm thawj 4 tus lej yog tib yam, lawv yog "kev puas tsuaj", "txiav tsis kam", "resilience", thiab "raug tsis kam". Cov ntaub ntawv loj dua, cov yam ntxwv zoo dua.
Tsab ntawv thib tsib lus Askiv kuj qhia tias "txiav tsis kam", tab sis tus qauv xeem yog txawv ntawm tus lej thib ob, thiab cov txheej txheem ntawm kev qhia txog qib kev txiav kuj tseem txawv, uas yuav piav qhia hauv qab no.
Tsab ntawv thib rau lus Askiv qhia tias "kev cuam tshuam tsis zoo", uas tseem qhia los ntawm cov ntawv Askiv. Tab sis tus lej thib rau yuav tshwm sim tsuas yog tias qhov kev sim cuam tshuam tau ua tiav, thiab yog tias nws tsis ua tiav, yuav muaj 5 tus lej ib txwm muaj.
Txawm hais tias 2016 version ntawm tus txheej txheem tau siv rau ntau tshaj plaub xyoos, tseem muaj ntau cov hnab looj tes qub ntawm lub khw. Cov hnab looj tes tiv thaiv uas tau lees paub los ntawm cov neeg siv tshiab thiab qub yog cov hnab looj tes tsim nyog, tab sis nws raug pom zoo kom yuav cov hnab looj tes tiv thaiv nrog 6 tus lej thiab cov ntawv los qhia cov yam ntxwv ntawm cov hnab looj tes.
Nrog rau qhov tshwm sim ntawm ntau cov ntaub ntawv tshiab, nws yog ib qho tsim nyog yuav tsum muaj peev xwm sib faib ua ke los qhia qhov kev txiav tsis kam ntawm cov hnab looj tes. Hauv txoj kev faib qib tshiab, tsis muaj qhov sib txawv ntawm A1-A3 thiab thawj 1-3, tab sis A4-A9 piv nrog cov thawj 4-5, thiab thawj ob qib muab faib ua 6 qib, uas tuaj yeem siv tau. rau hnab looj tes. Txiav tsis kam ua ib qho kev qhia ntxaws ntxiv txog qib kev faib tawm.
Nyob rau hauv ANSI specification, tsis tsuas yog daim ntawv qhia ntawm qib yog upgraded, tab sis kuj cov qauv xeem. Keeb kwm, qhov kev xeem siv ASTM F1790-05 tus qauv, uas tso cai rau kev sim ntawm TDM-100 cov cuab yeej (tus qauv xeem yog hu ua TDM TEST) lossis CPPT cov khoom (tus qauv xeem hu ua COUP TEST). Tam sim no nws siv ASTM F2992-15 tus qauv, uas tsuas yog tso cai rau kev siv TDM TEST ua kev sim.
✬Qhov txawv ntawm TDM TEST thiab COUP TEST yog dab tsi?
COUP TEST siv lub voj voog nrog lub siab ntawm 5 Copernicus tig thiab txiav cov khoom siv hauv hnab looj tes, thaum TDM TEST siv lub taub hau riam los nias rau ntawm cov khoom siv hnab looj tes ntawm qhov sib txawv, reciprocating ntawm qhov ceev ntawm 2.5 mm / s laser txiav.
Txawm hais tias tus txheej txheem tshiab EN 388 xav kom muaj ob txoj kev xeem, COUP TEST thiab TDM TEST, tuaj yeem siv tau, tab sis nyob rau hauv COUP TEST, yog tias nws yog ib qho zoo heev los tiv thaiv laser txiav cov khoom raw, cov hniav tuaj yeem ua blunt. Yog hais tias lub laser txiav tom qab 60 laps, nws yog xam tias lub taub hau cutter ua blunt, thiab TDM TEST yog yuav tsum tau.
Nws yuav tsum raug sau tseg tias yog tias qhov kev ua haujlwm siab tiv thaiv laser txiav hnab looj tes tau dhau TDM TEST, ces "X" tuaj yeem sau rau ntawm tus lej thib ob ntawm cov qauv pov thawj. Lub sijhawm no, qhov kev txiav tawm tsuas yog qhia los ntawm tsab ntawv Askiv thib tsib.
Yog tias nws tsis yog rau cov hnab looj tes tiv thaiv zoo heev, ces cov khoom siv hnab looj tes tsis zoo li yuav npub lub taub hau ntawm COUP TEST. Lub sijhawm no, TDM TEST tuaj yeem raug tshem tawm, thiab tus lej thib tsib ntawm cov qauv kev pov thawj yog qhia los ntawm "X".
Cov ntaub ntawv nyoos rau cov hnab looj tes uas tsis zoo txiav-resistant tsis tau kuaj rau TDM TEST lossis kev cuam tshuam tsis zoo. ↑ Cov khoom siv raw ntawm cov hnab looj tes tiv thaiv zoo heev, TDM TEST tau ua tiav, COUP TEST thiab kev ntsuas kev tiv thaiv tsis tau ua tiav.
