Kev faib cov khoom siv hluav taws xob hauv tsev los ntawm qib kev siv hluav taws xob tau qhia hauv Tebchaws Europe hauv nruab nrab-90s. Nyob rau hauv Russia, txij li thaum 2011, xws li cov cim yuav tsum tau yuav tsum tau nyob rau hauv loj cov khoom siv nyob rau hauv tsev, uas muaj xws li tub yees, ntxhua khaub ncaws thiab tshuab ntxhua khaub ncaws, hluav taws xob qhov cub thiab qhov cub, freezers, cua txias thiab cua sov, TVs, microwave ncu, hluav taws xob teeb thiab dej rhaub. Txhua lub cuab yeej hluav taws xob hauv tsev yuav tsum muaj daim ntawv nplaum uas qhia cov chav kawm hluav taws xob. Cov ntaub ntawv zoo sib xws tau muab luam tawm hauv phau ntawv hla tebchaws.
chav kawm lub zog yog qhia los ntawm cov ntawv Latin los ntawm A txog G. Cov khoom siv nyiaj txiag tshaj plaws A, cov khoom siv hluav taws xob siab tshaj plaws ntawm cov khoom siv G. yog tsim los ua super A, A +, A++. Kom yooj yim rau kev nkag siab, tsab ntawv sau npe sib raug rau qee yam xim. Zog chav kawm A yog qhia nyob rau hauv ci ntsuab, chav B nyob rau hauv lub teeb ntsuab, D nyob rau hauv daj, G nyob rau hauv liab.
Kom paub meej,Lub luag haujlwm no ua haujlwm li cas, xav txog cov tub yees - lawv ua haujlwm yuav luag txhua lub sijhawm, thiab lawv feem hauv kev siv hluav taws xob yog qhov pom tau. Txhawm rau txiav txim siab hauv chav kawm, lawv coj tus nqi tiag tiag ntawm hluav taws xob, tsim kev sim, thiab faib nws los ntawm tus qauv tus nqi, uas yog txiav txim siab los ntawm cov qauv sib xyaw nrog ntau yam. Rau chav kawm A, qhov piv txwv no yog 42-55%, chav kawm B - 56-75%, C - 76-90%, D - 91-100%, chav kawm E, F, G - siab dua 100%. Rau cov qauv kev lag luam super A +, A ++, A+++ - tsawg dua 41%. Raws li koj tuaj yeem pom, cov qauv kev lag luam siv hluav taws xob tsawg dua peb zaug dua li tus qauv.
Rau cov tshuab cua txias, chav kawm siv hluav taws xob tau txiav txim siab los ntawm ob qhov ntsuas: qhov piv ntawm qhov ua tau txias thiab hluav taws xob siv tib lub sijhawm, thiab qhov sib piv tsuas yog rau cua sov. Rau cov tshuab ntxuav tais diav, kev siv dej yog qhov tseem ceeb. Rau cov tshuab ntxhua khaub ncaws, qhov ntsuas no yog txiav txim siab raws li kev siv lub zog ib kilogram ntawm ntxhua khaub ncaws. Thaum txiav txim siab cov chav kawm siv hluav taws xob rau qhov cub, lawv qhov ntim thiab kev siv tam sim no raug coj mus rau hauv tus account; rau TVs, qhov sib piv ntawm lub zog siv rau qhov screen yog xam.
Kev siv cov khoom siv hluav taws xob high-end yuav txuag tau ntawm cov nqi hluav taws xob, txawm li cas los xij, tus nqi ntawm cov qauv nrog cov chav kawm siv hluav taws xob ntau dua. Qhov no yog vim kev siv cov khoom siv niaj hnub, thev naus laus zis ntau dua, thiab yog li cov ntsiab lus kim dua.
Xaiv cov cuab yeej tshiab, tshwj tsis yog tsim, tsim khoom, qhov ntevthiab lub zog, xyuam xim rau cov chav kawm ntawm lub zog. Ntxiv nrog rau qhov tseem ceeb ntawm kev txuag nyiaj hauv kev them nqi hluav taws xob, qhov ubiquity ntawm cov cuab yeej siv tau zoo yuav txo tus nqi ntawm cov peev txheej ntuj, ntau yam uas tsis yog txuas ntxiv dua tshiab. Qhov no, nyob rau hauv lem, yuav ua rau me ntsis txhim kho ib puag ncig qhov teeb meem, uas yog zuj zus zuj zus nyob rau hauv ib xyoos.
