Nws yog lub luag haujlwm thiab kev lav phib xaub ntawm txhua tus neeg ua haujlwm tau zoo los ua qhov kev tshuaj xyuas zoo thiab kuaj cov hnab ev ntawv thiab tiv thaiv kev nyab xeeb ntawm cov tub ntxhais kawm cov khoom siv.
Cov ntsiab lus ntawm tsab xov xwm no: kev tshuaj xyuas lub hnab ev ntawv, kev tshuaj xyuas lub hnab ev ntawv
01. Cov qauv tshuaj ntsuam xyuas
Kev tshuaj xyuas cov tub ntxhais kawm lub hnab ev ntawv feem ntau siv QB / T 2858-2007 "Student Bookbags" tus qauv, uas tsim nyog rau kev tso cov phau ntawv qhia, pab qhia, thiab cov khoom siv rau tub ntxhais kawm, nrog rau ib leeg thiab ob lub xub pwg pluaj thiab cov hnab nqa nqa tau. Hauv kev tshuaj xyuas thiab kev sim tshwj xeeb, cov qauv hauv qab no muaj xws li: GB / T 2912.1 "Kev txiav txim siab ntawm Formaldehyde hauv Textiles - Ntu 1: Dawb Hydrolyzed Formaldehyde (Txoj Kev Siv Dej)", GB / T 3920 "Xim Fastness Test rau Textile Khoom - Xim ceev Rau Rubbing", GB 6675-2003 "National Toy Safety Technical Specification", GB 21207-2007 "Kev Nyab Xeeb Kev Nyab Xeeb Rau Cov Tub Ntxhais Kawm" QB/T 3826 "Corrosion resistance test method for metal coatings and chemically treated coatings of light industrial products - Neutral ntsev tsuag tshuaj ntsuam (NSS) txoj kev", QB / T 3832 "Kev ntsuam xyuas ntawm corrosion xeem tau rau hlau coatings ntawm lub teeb industrial khoom", thiab lwm yam.
02. Cov ntsiab lus tshuaj xyuas thiab cov txheej txheem
Cov cim tseem ceeb rau kev soj ntsuam zoo ntawm cov tub ntxhais kawm lub hnab ev ntawv suav nrog qhov hnyav, deformation, stitching lub zog, xim ceev rau kev sib txhuam, kev nyab xeeb ntawm cov khoom siv, thiab formaldehyde cov ntsiab lus ntawm cov khoom siv ntaub. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them nyiaj rau kev nplij siab ntawm lub nraub qaum thaum siv lub hnab ev ntawv, nrog rau kev yooj yim ntawm kev siv cov hnab ev khoom thiab cov tes tuav.
Ntxiv nrog rau kev xa mus rau kev tshuaj xyuas lub nra, muaj ntau lub ntsiab lus uas yuav tsum tau them nyiaj tshwj xeeb rau hauv kev tshuaj xyuas cov hnab ev ntawv. Cov kev xav tau sib txawv me ntsis: cov kev xav pom - qhov zoo ntawm lub hnab ev ntawv yuav tsum ua raws li cov cai hauv qab no: tag nrho cov tsos, tag nrho cov duab, cov kab ntshiab, tiaj tus thiab du adhesion, upright, thiab tag nrho huv si. Zipper, nrog qhov sib npaug ntawm ntug, ncaj stitching, tsis muaj cov hniav ploj lawm, thiab rub thiab kaw. Accessories thiab installation yuav tsum muaj ib tug du nto, ci thiab tsis muaj xeb residue, plating plating, koob qhov, blistering, tev, thiab detachment. Cov khoom siv yuav tsum tau muab ntsia ruaj khov. Cov kab suture yuav tsum tsim nyog rau qhov zoo ntawm cov ntaub thiab hauv ob sab phlu siv, nrog rau qhov zoo thiab xim txuam txhua qhov. Cov ntaub yuav tsum tsis muaj kev puas tsuaj los yog weft, thiab yuav tsum tsis txhob hla threads, threads, marks, stains, los yog blemishes. Lub tshuab luam ntawv zoo li yuav tsum muaj cov qauv meej, xim ci, muaj tseeb overprinting, tsis ntws los yog raug tus cwj mem, thiab tsis muaj xim fading. Suture stitches yuav tsum sib phim rau sab sauv thiab sab xov, nrog ncaj stitches thiab sib npaug koob sib nrug. Tsis pub stitches los yog hla stitches tsis pub nyob rau pem hauv ntej loj nto thiab pem hauv ntej cover ntawm lub hnab ntawv. Tsis pub skewed stitching ntev tshaj 12mm. Ib qho khoom lag luam yuav tsum tsis pub ntau tshaj ib rab koob khoob lossis rab koob uas ploj lawm, thiab tsis pub ntau tshaj ob koob khoob, koob uas ploj lawm, lossis rab koob hla.
Load bearing test - Qhov kev xeem ntawm cov menyuam kawm ntawv lub hnab ev ntawv yuav tsum kom cov tes tuav, cov hlua, cov hlua hloov, thiab cov hooks yuav tsum tsis txhob poob los yog tawg raws li qhov teev tseg, thiab lub hnab lub cev yuav tsum tsis txhob tawg.
Qhov hnyav yuav tsum muaj raws li hauv qab no:
Serial Number Specification (qhov siab) / hli Load / kg1＜30032300-400 (tsis suav 400) 53400-50074＞5 0010
Kev xeem viav vias - Lub hnab ev khoom tau thauj khoom raws li kev cai, thiab cov hlua khi thiab cov tes tuav tau raug kuaj cais: dai saum huab cua, cov hlua khi nyob rau hauv lub xeev ntev tshaj plaws, lossis kho qhov kev ncua deb ntawm lub viav vias axis mus rau 50cm-60cm, viav vias 30 zaug ( pem hauv ntej thiab rov qab li 1 zaug), thiab lub viav vias lub kaum sab xis yog (60 ± 3) °. Tom qab lub viav vias nres, xyuas seb lub hnab ev ntawv pluaj, tes tuav, kho cov hlua, thiab hooks puas ruaj ntseg. Ntsuas seb qhov deformation ntawm cov khoom sib txuas ntau tshaj 20% piv rau qhov ntev ntev li ntawm 2 feeb. Static and drop test – Ntsuas qhov ntev ntawm cov khoom uas ua haujlwm raws li kev sib txuas ntawm lub hnab ev ntawv. Lub hnab ev ntawv yuav tsum tau thauj khoom 1.2 npaug ntawm qhov hnyav, tshem tawm hauv huab cua (nrog lub pluaj nyob rau hauv lub xeev ntev tshaj plaws), thiab hauv qab ntawm lub hnab ev ntawv yuav tsum yog 60cm saum toj no hauv av (nrog rau cov ntoo tawv), kom nws sib npaug. stressed thiab nyob rau hauv ib tug static thiab upright lub xeev. Tom qab 30 feeb, poob vertically thiab xyuas seb cov hlua khi, tuav, kho cov hlua, thiab shackles puas ruaj ntseg. Ntsuas qhov ntev ntawm cov hlua khi, tuav, kho cov hlua, thiab shackles uas ua haujlwm sib txuas hauv 2 feeb, thiab xyuas seb qhov deformation ntau tshaj 20% piv rau qhov ntev ntev.
