Pali mitundu yambiri ya magolovesi osamva odulidwa pamsika. Kodi khalidwe la magolovesi odulidwa ndi abwino, omwe si ophweka kuvala, ndi momwe mungasankhire kupewa kusankha kolakwika?
Magolovesi ena osamva odulidwa pamsika ali ndi mawu oti "CE" kumbuyo. Kodi "CE" ikutanthauza mtundu wina wa satifiketi yovomerezeka?
Chizindikiro cha "CE" ndi chiphaso chachitetezo, chomwe chimatengedwa ngati pasipoti kuti opanga atsegule ndikulowa mumsika waku Europe. CE amatanthauza mgwirizano wa ku Ulaya (European Conformity). Poyambirira CE amatanthawuza mulingo waku Europe, ndiye kupatula kutsatira muyezo, ndi mikhalidwe iti yomwe magolovesi osamva ayenera kutsatira?
Magolovesi odzitchinjiriza popewa kuwonongeka kwamakina amagwirizana kwambiri ndi en standard EN 388, mtundu waposachedwa ndi mtundu wa 2016, ndi American standard ANSI/ISEA 105, mtundu waposachedwa ndi 2016.
M'mafotokozedwe awiriwa, mafomu ofotokozera a msinkhu wotsutsa odulidwa amasiyana.
Magolovesi osamva odulidwa omwe amatsimikiziridwa ndi en standard adzakhala ndi chishango chachikulu chokhala ndi mawu oti "EN 388" pamenepo. Pali manambala 4 kapena 6 a data ndi zilembo za Chingerezi pansi pa chishango chachikulu. Ngati ndi data ya 6 ndi zilembo za Chingerezi, zimasonyeza kuti EN 388: 2016 yatsopano imagwiritsidwa ntchito, ndipo ngati ili ndi manambala 4, imasonyeza kuti ndondomeko yakale ya 2003 imagwiritsidwa ntchito.
Matanthauzo a manambala 4 oyambirira ndi ofanana, ndi "abrasion resistance", "cut resistance", "resilience", ndi "puncture resistance". Zomwe zili zazikulu, zimakhala zabwinoko mawonekedwe.
Kalata yachisanu ya Chingerezi imasonyezanso "kukana kudulidwa", koma muyeso woyesera ndi wosiyana ndi wa nambala yachiwiri, ndipo njira yowonetsera kukana kudulidwa ndi yosiyana, yomwe idzafotokozedwa mwatsatanetsatane pambuyo pake.
Kalata yachisanu ndi chimodzi ya Chingerezi imasonyeza "impact resistance", yomwe imasonyezedwanso ndi zilembo za Chingerezi. Koma nambala yachisanu ndi chimodzi idzawonekera pokhapokha ngati kuyesa kwa zotsatira kukuchitika, ndipo ngati sikunachitike, padzakhala manambala 5 nthawi zonse.
Ngakhale kuti mtundu wa 2016 wa en standard wakhala ukugwiritsidwa ntchito kwa zaka zoposa zinayi, padakalipo mitundu yambiri yakale ya magolovesi pamsika. Magolovesi osamva odulidwa omwe amatsimikiziridwa ndi ogwiritsa ntchito atsopano ndi akale onse ndi magolovesi oyenerera, koma ndi bwino kugula magolovesi odulidwa omwe ali ndi manambala 6 ndi zilembo kuti asonyeze makhalidwe a magolovesi.
Kubwera kwa zida zambiri zatsopano, ndikofunikira kuti muzitha kugawa mochenjera kuti muwonetse kukana kodulidwa kwa magolovesi. Munjira yatsopano yogawa giredi, palibe kusiyana pakati pa A1-A3 ndi 1-3 yoyambirira, koma A4-A9 ikuyerekezedwa ndi 4-5 yoyambirira, ndipo magiredi awiri oyambilira amagawidwa m'magiredi 6, omwe angagwiritsidwe ntchito. za magolovesi. Cut resistance imakhala ndi tsatanetsatane wamagulu amtundu.
M'mafotokozedwe a ANSI, osati mawonekedwe amtundu wokhawo omwe amakwezedwa, komanso muyeso woyesera. Poyambirira, mayesowa adagwiritsa ntchito muyezo wa ASTM F1790-05, womwe umalola kuyesa pa zida za TDM-100 (muyezo woyeserera umatchedwa TDM TEST) kapena zida za CPPT (yeyeyezo imatchedwa COUP TEST). Tsopano imagwiritsa ntchito muyezo wa ASTM F2992-15, womwe umangolola kugwiritsa ntchito TDM TEST kumachita kuyesa.
✬Kodi pali kusiyana kotani pakati pa TDM TEST ndi COUP TEST?
COUP TEST imagwiritsa ntchito tsamba lozungulira ndi kukakamiza kwa 5 Copernicus kuti itembenuzire ndikudula zida zamagolovesi, pomwe TDM TEST imagwiritsa ntchito mutu wa mpeni kukanikizira zida za glove pazovuta zosiyanasiyana, kubwezerananso pa liwiro la 2.5 mm / s laser kudula.
Ngakhale EN 388 yatsopano imafuna kuti miyezo iwiri yoyesera, COUP TEST ndi TDM TEST, ingagwiritsidwe ntchito, koma pansi pa COUP TEST, ngati ili yabwino kwambiri yotsutsa laser kudula zopangira, tsamba lozungulira likhoza kukhala losamveka. Ngati laser imadula Pambuyo pa mipingo 60, imawerengedwa kuti mutu wodula umakhala wosamveka, ndipo TDM TEST ndiyofunikira.
Zindikirani kuti ngati gulovu yolimbana ndi laser yogwira ntchito kwambiri yadutsa TDM TEST, ndiye kuti "X" ikhoza kulembedwa pa nambala yachiwiri yachitsimikiziro. Panthawiyi, kukana kodulidwa kumangosonyezedwa ndi kalata yachisanu ya Chingerezi .
Ngati simagulovu abwino kwambiri osamva, ndiye kuti zida zamagetsi sizingasokoneze mutu wodula wa COUP TEST. Panthawiyi, TDM TEST ikhoza kuchotsedwa, ndipo nambala yachisanu ya ndondomeko yotsimikizira ikuwonetsedwa ndi "X".
Zida zopangira magolovu osagwira ntchito bwino kwambiri sizinayesedwe ku TDM TEST kapena kukana mphamvu. ↑ Zopangira zopangira ma glovu abwino kwambiri osamva, TDM TEST yachitika, COUP TEST ndi kuyesa kwamphamvu sikunachitike.
