Vim li cas thiaj kuaj xyuas khau kev nyab xeeb ua ntej xa khoom?
Nws tseem ceeb rau ntau yam. Kev nyab xeeb khau yog siv los tiv thaiv cov neeg ua haujlwm ntawm qhov chaw. Yog tias cov ntiv taw steel lossis tiv thaiv - nkag mus midsole ua tsis tau raws li qhov yuav tsum tau ua, cov neeg siv yuav ntsib kev raug mob hnyav thiab cov neeg yuav khoom yuav tau txais kev lav phib xej. Yog tias cov khoom tsis raug tuaj txog ntawm qhov chaw nres nkoj, cov neeg yuav khoom tuaj yeem tsis lees txais cov khoom xa tuaj. Tus nqi thauj khoom ntxiv thiab nqi chaw nres nkoj yuav tshwm sim.
Kev tshuaj xyuas ntawm lub Hoobkas pab ntes cov teeb meem thaum ntxov thiab kho lawv ua ntej xa khoom xa tuaj. Nws tseem kuaj xyuas qhov sib txawv ntawm cov xim, stitching thiab kua nplaum teeb meem kom paub tseeb tias cov khoom sib phim cov qauv pom zoo. Dhau li ntawd, peb txheeb xyuas cov cim shipping thiab kom muaj nuj nqis los tiv thaiv kev sib xyaw thiab ua yuam kev thaum lub sij hawm kev lis kev cai clearance.
Kev soj ntsuam Standards
Txoj cai coj mus kuaj: AQL 0 rau qhov tsis xws luag, AQL 2.5 rau qhov tsis xws luag loj, AQL 4.0 rau qhov tsis xws luag me, random sampling tom qab GB / T2828.1.
1. Cov ntaub ntawv thiab kos cim
Txheeb xyuas cov ntawv pov thawj kev nyab xeeb, cov cim tiv thaiv, qauv thiab qhov loj me kom phim qhov kev txiav txim yuav khoom. Txheeb xyuas cov ntaub ntawv luam tawm ntawm nkawm khau, insole, sab hauv lub thawv thiab cov thawv sab nraud. Paub meej tias qib kev tiv thaiv thiab xav tau cov cim xa tawm.
2. Kev tshuaj xyuas qhov muag
Cov nkawm khau yuav tsum muaj xim sib xws thiab cov khoom siv. Tsis muaj kab nrib pleb, qhov, hnyav stain, xim sib txawv los yog mildew rau saum. Stitching yuav tsum sib npaug, tsis muaj hla lossis tawg. ntiv taw cap zaum hauv txoj hauj lwm kom raug, tsis qaij. Kos ib leeg rau cov kua nplaum tev, npuas thiab deformation. Hlau eyelets thiab buckles tsis muaj burr thiab xeb.
3. Dimension thiab kev ua haujlwm
Ntsuas khau ntev thiab dav. Size kam rau ua yuav tsum tau raws li tus neeg yuav tsum tau muaj. Sab laug thiab sab xis khau kom symmetry. Tus qauv thiab thickness ua raws li specification.
4. Kev kuaj xyuas kev nyab xeeb
Xyuas ntiv taw cap kom ruaj khov. Rau cov khau tiv thaiv puncture, paub meej tias sab hauv los tiv thaiv - ntawv nkag rau hauv qhov chaw raug. Khoov ib leeg ib zaug ntxiv kom pom kev tawg lossis delamination. Rau insulating khau kev nyab xeeb, kos cim thiab lwm yam kev xeem ntawv tshaj tawm.
5. Cov khoom siv thiab ntim khoom
Txhua khub ntim rau hauv ib lub thawv xim nrog phau ntawv, shoelaces tiav. Cov thawv sab nraud nrog kev tiv thaiv noo noo, shipping cim raug, tsis ntub los yog crushed lub thawv. Paub meej tias ntim khoom kom muaj nuj nqis.
6. Kev txiav txim tsis raug
Cov teeb meem tseem ceeb (AQL0): Kev tiv thaiv kev nyab xeeb tsis ua haujlwm, tsis lees txais tag nrho cov khoom.
Cov teeb meem loj (AQL2.5): Cov ntiv taw tsis zoo, qhov loj ntawm cov kua nplaum sib cais, qhov loj me, cim tsis raug, pom tseeb xim txawv.
Cov teeb meem me me (AQL4.0): Lub teeb smudge, xoob xov, tsis muaj kev cuam tshuam rau kev nyab xeeb thiab kev ua haujlwm.
