DIN cov qauv yog dab tsi thiab vim li cas nws tseem ceeb kom paub cov cim no?

Thaum tshawb xyuas cov lus qhia rau ntau yam khoom suav nrog cov ntsia hlau, peb feem ntau tuaj hla "DIN" cov npe thiab cov lej sib raug.Rau cov tsis tau pib, cov ntsiab lus no tsis muaj lub ntsiab lus hauv cov ntsiab lus.Tam sim no, nws yog ib qho tseem ceeb heev uas yuav tau xaiv hom ntsia hlau zoo.Peb tshuaj xyuas seb DIN cov qauv txhais li cas thiab vim li cas koj yuav tsum nyeem lawv.
Lub ntsiab lus DIN nws tus kheej los ntawm lub npe ntawm lub koom haum German rau Standardization (Deutsches Institut für Normung), uas sawv cev rau cov qauv tsim los ntawm lub cev.Cov qauv no hais txog qhov zoo, durability thiab daim ntawv thov ntawm cov khoom tiav.
DIN qauv npog ntau yam teb.Lawv siv tsis yog nyob rau hauv lub teb chaws Yelemees, tab sis kuj nyob rau hauv ntau lwm lub teb chaws nrog rau Poland.Txawm li cas los xij, tus qauv DIN hloov mus rau cov npe PN (Polish Standard) thiab ISO (General World Standard) muaj ntau cov cim, nyob ntawm cov khoom lawv xa mus.Piv txwv li, muaj ntau ntau hom DIN cov qauv ntsig txog bolts, tag nrho cov cim kev sib txuas, txawm tias cov khoom siv tshwj xeeb. Cov khoom siv pab kuj muaj cov qauv DIN.
Cov qauv DIN siv tau rau cov tuam txhab ntsia hlau kuj tau muab faib ua ntau hom.Ib lub npe tshwj xeeb, DIN + tus lej, txhais ib hom ntsia liaj qhov rooj tshwj xeeb.Qhov kev faib no tuaj yeem pom nyob rau hauv cov qauv hloov pauv cov lus npaj los ntawm bolt manufacturers.
Piv txwv li, feem ntau nrov thiab feem ntau siv ntsia liaj qhov rooj hom yog DIN 933 bolts, piv txwv li hexagon taub hau bolts thiab tag nrho threaded bolts, ua los ntawm carbon steel ntawm txhua yam khoom siv chav kawm ntawv 8.8 los yog stainless hlau A2.DIN 931 screws kuj feem ntau nrhiav, piv txwv li incompletely threaded hexagon screws, ua los ntawm cov hlau 2 A8.
Tus qauv DIN yog tib yam li cov ntsia hlau.Yog cov khoom lag luam tsis suav nrog lub npe tseeb ntawm lub ntsia liaj qhov rooj tab sis lub npe DIN, lub rooj hloov pauv yuav tsum tau sab laj. Piv txwv li, DIN screws.Qhov no yuav pab koj nrhiav cov khoom tsim nyog thiab hloov kho rau koj cov kev xav tau thiab daim ntawv thov.Yog li ntawd, kev paub txog DIN tus qauv yog sib npaug rau kev paub txog cov ntsia hlau hom.Yog li ntawd, nws yog ib qho tsim nyog rau kev txiav txim siab rau cov ntsiab lus tseem ceeb hauv kev tshawb nrhiav cov ntsiab lus. Polish thiab thoob ntiaj teb cov qauv.
