Qhov tseem ceeb ntawm kev tswj hwm qhov kub ntawm preforms
Qhov kub ntawm qhov kub ntawm qhov ntsuas kub yog hais txog qhov ntsuas kub ntawm cov preforms thaum kub ntws los ntawm lawv thaum lub sijhawm tsim khoom. Kev tswj qhov kub ntawm qhov ntsuas kub ntawm cov preforms yog qhov tseem ceeb lav rau kev tsim khoom thiab tuaj yeem cuam tshuam rau kev ua tau zoo thiab tso zis ntawm cov khoom. Kev tswj hwm kom raug qhov kub ntawm qhov kub ntawm cov preforms tsis tuaj yeem txhim kho kev ua tau zoo, tab sis tseem txhim kho cov khoom lag luam zoo thiab txo cov nqi tsim khoom.
Cov hau kev thiab cov kev ceev faj rau kev tswj hwm qhov kub ntawm preforms
1. Cov hau kev rau kev tswj hwm kub
(1) Cov kev cai ntsuas kub nyob rau hauv pem hauv ntej thaj chaw: nce qhov kub nyob hauv thaj chaw pem hauv ntej tuaj yeem nce cov khoom tawm thiab txo cov khoom lag luam tsis zoo.
(2) Cov kev cai ntsuas kub hauv thaj chaw nruab nrab: Kev tswj qhov kub thiab cua sov ua rau cov khoom lag luam nruab nrab thiab cov kev xav tau los ua kom haum raws li cov khoom yuav tsum tau ua.
(3) Cov kev cai kub nyob hauv thaj tsam rov qab: qhov ntsuas kub nyob hauv thaj chaw tom qab feem ntau tau teeb tsa ntawm qhov nruab nrab ntawm cov chaw hauv ntej thiab nruab nrab. Siab dhau los yog qis dhau yuav cuam tshuam rau lub cev lub cev ntawm cov khoom.
2. Kev ceev faj
(1) qhov ntsuas kub ntawm qhov xav tau yuav tsum tau hloov kho raws li cov khoom yuav tsum tau ua.
(2) Qhov ntsuas kub ntawm cov qib yuav tsum ruaj khov thiab yuav tsum tsis txhob hloov kho ntau dhau.
(3) Qhov kub thiab txias yuav tsum tsis txhob siab dhau los lossis qis dhau thiab yuav tsum tau tswj hwm hauv cov ntau yam tsim nyog.
(4) Qhov hloov kho qhov hloov kom txog qhov kub thiab txias dua tshiab yuav tsum raug kho nyob rau lub sijhawm kom tsis txhob muaj xwm txheej ntau lawm.
