Taw qhia
OIML R134-1 thiab GB / T 21296.1-2020 yog ob qho tib si qauv uas muab cov lus qhia tshwj xeeb rau cov tshuab hnyav hnyav (WIM) siv rau tsheb loj. OIML R134-1 yog tus qauv thoob ntiaj teb uas tau muab los ntawm International Organization of Legal Metrology, siv tau thoob ntiaj teb. Nws teev cov kev cai rau WIM systems raws li cov qhab nia raug, tso cai yuam kev, thiab lwm yam kev qhia tshwj xeeb. GB / T 21296.1-2020, ntawm qhov tod tes, yog Suav lub teb chaws tus qauv uas muaj cov lus qhia dav dav thiab cov kev cai raug tshwj xeeb rau Suav cov ntsiab lus. Kab lus no yog tsom los sib piv cov qhab-nees uas yuav tsum tau muaj ntawm ob tus qauv no los txiav txim seb qhov twg yog qhov yuav tsum tau ua kom raug nruj dua rau WIM systems.

●Tib qag load thiab qag pawg load: G, H
2.2 Qhov siab tshaj plaws tso cai yuam kev (MPE)
Tsheb hnyav tag nrho (Dynamic Weighing):
●Kev txheeb xyuas thawj zaug:±0.5d -±1.5d ib
●Kev tshuaj xyuas hauv kev pabcuam:±1.0d -±3.0d ib
Ib Qag Load thiab Axle Group Load (Ob-axle Rigid Reference Vehicles):
●Kev txheeb xyuas thawj zaug:±0.25% -±4.00%
●Kev tshuaj xyuas hauv kev pabcuam:±0.50% -±8.00%
2.3 Scale Interval (d)
●Qhov nruab nrab qhov nruab nrab sib txawv ntawm 5 kg mus rau 200 kg, nrog rau cov sij hawm sib txawv ntawm 500 txog 5000.
●Qhov nruab nrab qhov nruab nrab ntawm lub tsheb qhov hnyav tag nrho thiab qhov hnyav ib nrab yog 50 kg thiab 5 kg, feem.
3. Kev Ntsuas Kev Sib Piv ntawm Ob Tus Qauv
3.1 Hom Cov Qib Siab
●OIML R134-1: Feem ntau tsom rau cov qhab nia raug.
●GB/T 21296.1-2020: suav nrog ob qho tib si qib pib thiab qhov tseeb ntxiv, ua rau kev faib tawm kom ntxaws thiab ua kom zoo dua.
3.2 Qhov siab tshaj qhov yuam kev (MPE)
●OIML R134-1: Qhov ntau ntawm qhov ua yuam kev siab tshaj plaws rau lub tsheb qhov hnyav tag nrho yog dav dua.
●GB/T 21296.1-2020: Muab ntau qhov tshwj xeeb tshaj qhov tso cai yuam kev rau qhov hnyav hnyav thiab nruj dua qhov yuav tsum tau ua rau qhov ntsuas qhov sib txawv.
3.3 Scale Interval thiab qhov hnyav tsawg kawg nkaus
●OIML R134-1: Muab ntau qhov sib txawv ntawm qhov ntsuas qhov ntev thiab qhov ntsuas qhov ntsuas qhov tsawg kawg nkaus.
●GB/T 21296.1-2020: Npog cov kev cai ntawm OIML R134-1 thiab qhia ntxiv txog qhov yuav tsum muaj qhov hnyav tsawg kawg nkaus.
Xaus
Los ntawm kev sib piv,GB/T 21296.1-2020yog qhov nruj dua thiab cov ncauj lus kom ntxaws nyob rau hauv nws cov qib raug, qhov siab tshaj qhov yuam kev tso cai, ntsuas lub sijhawm, thiab qhov xav tau qhov hnyav tsawg kawg nkaus. Yog li ntawd,GB/T 21296.1-2020imposes ntau nruj thiab meej qhov yuav tsum tau rau dynamic hnyav (WIM) duaOIML R134-1.
