Standard rau kev poob siab tsis kam ntawm moos thiab watches
Tus qauv shockproof rau moos thiab watches yog ua raws li simulating qhov cuam tshuam uas lub moos yuav ntsib thaum poob ntawm qhov siab ntawm 1 meter mus rau kab rov tav hardwood nto. Nws yog muaj feem xyuam rau hom kev ntsuam xyuas ntawm watches cim tias "shockproof" thiab tsis siv rau ib tug neeg soj ntsuam ntawm tag nrho cov batch ntawm watch khoom. Nws yog qhov yuav tsum tau ua yam tsawg kawg nkaus rau cov watches cim tias "shockproof" QB/T 1898-93 "Clocks thiab Watches - Shockproof Watches", cov kev cai thiab cov txheej txheem xeem yog raws li hauv qab no:
Kev xav tau
1. Lub moos tsis tuaj yeem nres tom qab txhua qhov cuam tshuam.
2. Cov nyhuv residual: Quartz watches yuav tsum tsis pub tshaj 2s/d; Lwm hom watches yuav tsum tsis pub tshaj 60s / d.
3. Tom qab kuaj xyuas, lub moos yuav tsum tsis txhob cuam tshuam rau nws qhov kev ua haujlwm ib txwm lossis ua rau nws cov tsos mob tsis zoo (xws li khoov lossis hloov pauv ntawm tus taw tes, kev puas tsuaj rau cov khoom siv tsis siv neeg lossis daim ntawv qhia hnub, cov iav tawg, khoov cov ntaub ntawv taw, khoov lossis cov khoom sib tsoo, thiab cov nyees khawm puas).
Kev sim
1. Ntsuas qhov sib txawv ntawm lub sij hawm tam sim no ntawm lub moos ua ntej qhov kev sim cuam tshuam; Mechanical watch: Tom qab khiav rau 1 teev nrog ib lub strip tag nrho, sim qhov sib txawv tam sim no txhua hnub ntawm txoj haujlwm FH, 6H, thiab 9H ntawm lub moos, nrog lub sijhawm sim tsawg kawg 1 feeb ntawm txhua txoj haujlwm. Quartz saib: Ua haujlwm tsawg kawg 2 teev ua ntej ntsuas ntsuas qhov sib txawv ntawm lub sijhawm tam sim ntawm CH lossis FH txoj haujlwm ntawm lub moos.
2. Thawj qhov cuam tshuam: Txoj hauj lwm ntawm qhov cuam tshuam yog nyob rau sab ntawm lub moos ntawm "9 teev" thiab sib npaug rau lub dial nto;
3. Qhov cuam tshuam thib ob: Txoj hauj lwm ntawm qhov cuam tshuam yog nyob rau ntawm iav perpendicular mus rau saum npoo ntawm lub dial;
4. Ntsuas qhov sib txawv tam sim no diurnal tom qab cuam tshuam; Mechanical watch: 5 feeb tom qab qhov kawg ntawm qhov cuam tshuam thib ob, sim ntsuas qhov sib txawv ntawm lub sijhawm tam sim ntawm FH, 6H, thiab 9H txoj haujlwm ntawm lub moos ua ntu zus, nrog lub sijhawm sim tsawg kawg 1 feeb rau txhua txoj haujlwm. Quartz saib: Ntsuas qhov sib txawv ntawm qhov sib txawv ntawm CH lossis FH ntawm lub moos 5 feeb tom qab qhov kawg ntawm qhov cuam tshuam thib ob.
5. Xam cov nyhuv seem ntawm lub moos: Siv qhov sib txawv siab tshaj plaws nyob rau hauv qhov sib txawv tam sim no diurnal ntsuas ntawm tib txoj hauj lwm.
