Kev lag luam tus qauv ntxiv rau kev nyab xeeb khau:
Ua ntej, European Standard EN 344: 1997 "Tshwj xeeb kev nyab xeeb, kev tiv thaiv thiab ua haujlwm khau" Qhov no European Standard yog tsim los ntawm CEN / TC61 "Cov khoom tiv thaiv rau ko taw thiab ceg tiv thaiv" thiab nws secretariat yog ua los ntawm BSI.
Cov qauv no qhia txog cov qauv tsim thiab kev ua haujlwm ntawm cov khau kev nyab xeeb, xws li khau, sab sauv, khau, nplaig, insole thiab outsole.
Cov qauv kev xeem rau txhua yam uas tau teev tseg hauv tus qauv zoo ib yam li lwm cov qauv zoo sib xws. Txoj hauv paus ntsiab lus kuj tseem siv tau rau feem ntau khau kev nyab xeeb. Cov cim tseem ceeb yog:
a. Baotou cuam tshuam tsis kam
Qhov kev ntsuam xyuas qhov cuam tshuam yuav tsum tau ua nrog ib qho kev cuam tshuam rau steel ntawm qhov hnyav uas tau teev tseg. Qhov siab ntawm qhov sib txawv nyob rau hauv tus ntiv taw cap yuav tsum tsawg tshaj li tus nqi teev thaum lub hau ntiv taw raug cuam tshuam, thiab qhov tho qhov yuav tsum tsis txhob pom cov kab nrib pleb nkag mus rau hauv cov kev taw qhia ntawm qhov ntsuas axis. Nws yog tsim nyog sau cia tias lub teb chaws cov qauv muaj cov kev cai sib txawv ntawm qhov hnyav, specifications, cuam tshuam qhov siab thiab kev tsim kho ntawm lub tshuab kuaj. Qhov kev xeem tiag tiag yuav tsum tau paub qhov txawv.
b. Puncture kuj
Lub tshuab kuaj tau nruab nrog lub phaj siab uas lub ntsuas ntsia hlau ntsia. Cov ntsia hlau xeem yog lub taub hau nrog lub hau txiav, thiab qhov tawv ntawm tus ntsia thawv taub hau yuav tsum siab dua 60HRC. Cov qauv ib leeg yog muab tso rau ntawm lub chassis ntawm lub tshuab kuaj nyob rau hauv xws li ib txoj hauj lwm uas cov ntsia hlau xeem yuav pierced los ntawm lub outsole, thiab cov ntsia hlau xeem pierces tus ib leeg ntawm ib tug ceev ntawm 10 mm / min ± 3 mm / min kom txog rau thaum nkag mus. ua tiav. Lub zog loj tshaj plaws. Plaub lub ntsiab lus raug xaiv ntawm txhua tus tib leeg rau kev sim (tsawg kawg yog ib qho ntawm lub pob taws), txhua qhov taw qhia tsis pub tsawg dua 30 mm sib nrug, thiab qhov kev ncua deb ntawm ntug insole yog ntau dua 10 hli. Hauv qab ntawm qhov thaiv thaiv yuav tsum tau tho qhov nruab nrab ntawm cov blocks. Ob ntawm plaub lub ntsiab lus yuav tsum tau sim nyob rau hauv 10-15 hli ntawm ntug kab ntawm hauv qab ntawm cov nroj tsuag. Yog tias cov av noo cuam tshuam rau qhov tshwm sim, ib leeg yuav tsum tau muab tso rau hauv dej deionized ntawm 20 degree ± 2 degree rau 16 ± 1 h ua ntej kuaj.
c. Hluav taws xob cov khoom ntawm cov khau conductive thiab khau tiv thaiv static
Tom qab cov qauv khau tau hloov kho nyob rau hauv qhov chaw qhuav thiab ntub dej, lub pob hlau huv huv tau ntim rau hauv tib neeg cov khau thiab muab tso rau ntawm cov khoom siv hlau sojntsuam, thiab thawj ob qhov kev sojntsuam thiab qhov thib peb kev sojntsuam yog ntsuas los ntawm kev ntsuas cov tshuaj tiv thaiv. Kev tiv thaiv ntawm. Raws li ib txwm muaj, cov khau conductive yuav tsum tsis txhob siab dua l00K ohms; Cov khau tiv thaiv zoo li qub yuav tsum muaj kev tiv thaiv yuav tsum nyob nruab nrab ntawm 100K ohms thiab 100M ohms.
d. Kev ua haujlwm thermal rwb thaiv tsev
Siv cov khau ua piv txwv, lub thermocouple yog muab tso rau ntawm qhov chaw ntawm qhov chaw sib txuas insole, thiab lub pob steel tau ntim rau hauv cov khau. Kho qhov kub ntawm cov xuab zeb da dej mus rau 150 ° C ± 5 ° C, muab cov khau rau ntawm nws, ua rau cov xuab zeb hu rau lub outsole ntawm lub khau, siv lub ntsuas kub ntsuas ntsuas nrog lub thermocouple los ntsuas qhov kub ntawm lub insole thiab lub sib thooj lub sij hawm, muab qhov kub nce nkhaus. Qhov ntsuas kub tau nce los ntawm 30 feeb tom qab cov qauv tau muab tso rau hauv cov xuab zeb da dej tau xam. Feem ntau cov khau insulated yuav tsum muaj qhov kub thiab txias ntawm sab hauv ib sab ntawm qis dua 22 degree.
e. Lub zog nqus kev ua haujlwm ntawm pob luj taws
Cov ntsuas ntsuas muaj qhov siab tshaj plaws compression load ntawm 6000 N thiab yog nruab nrog ib lub cuab yeej rau kev sau cov load / deformation yam ntxwv. Cov khau nrog pob taws yog muab tso rau ntawm ib lub phaj hlau, thiab qhov kev xeem punch yog muab tso rau sab hauv ntawm lub pob taws rau ntawm lub insole. Cov load tau thov ntawm qhov ceev ntawm 10 mm / min ± 3 mm / min. Lub load / compression nkhaus yog plotted thiab absorbed zog E yog xam, qhia nyob rau hauv joules.
f. Cov kev xav tau rau cov uas tsis yog-slip outsole
Cov txheej txheem no qhia txog kev tiv thaiv kev sib tsoo ntawm ib leeg, tab sis qhia txog cov qauv tsim thiab cov lus qhia tshwj xeeb ntawm kev tiv thaiv kev sib tsoo, xws li lub thickness ntawm ib leeg, qhov siab ntawm qhov tsis-slip block, thiab qhov kev ncua deb ntawm ntug ntawm lub ib leeg.
