Pakali pano, pali mitundu yambiri ya magolovesi odulidwa pamsika.Kodi magalavu osamva bwino ndi abwino?Ndi iti yomwe ili yosavuta kutopa?Kodi mungasankhe bwanji kupewa kusankha kolakwika?
Magolovesi ena osamva odulidwa pamsika ali ndi mawu oti "CE" cham'mbuyo.Kodi "CE" ikutanthauza mtundu wina wa satifiketi?
Chizindikiro cha "CE" ndi chiphaso chachitetezo, chomwe chimatengedwa ngati chitupa cha visa chikapezeka kwa opanga kuti atsegule ndikulowa mumsika wogulitsa ku Europe.CE amatanthauza mgwirizano wa ku Ulaya (CONFORMITE EUROPEENNE).Poyambirira CE chinali tanthawuzo la muyezo waku Europe, kotero kuwonjezera pa mulingo wa magalavu osagwira ntchito, ndi zina ziti zomwe ziyenera kutsatiridwa?
Magolovesi oteteza chitetezo popewa kuvulala kwa zida zamakina ayenera kutsatira EN 388, mtundu waposachedwa ndi nambala ya mtundu wa 2016, ndi American standard ANSI/ISEA 105, mtundu waposachedwa ndi 2016.
M'mafotokozedwe awiriwa, kufotokozera kwa msinkhu wa kukana odulidwa kumasiyana.
Magolovesi osaduka omwe amatsimikiziridwa ndi en standard azikhala ndi chishango chachikulu chokhala ndi mawu akuti "EN 388" pamwamba.The manambala 4 kapena 6 deta ndi zilembo English pansi pa chimphona chishango chitsanzo.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.
Manambala 4 oyambirira ali ndi matanthauzo ofanana, omwe ndi "kuvala kukana", "kukana kudulidwa", "kulimba mtima", ndi "kukaniza kuwombera".Zomwe zili zazikulu, zimakhala zabwinoko mawonekedwe.
Kalata yachisanu ya Chingerezi imasonyezanso "kukana kudulidwa", koma muyeso woyesera ndi wosiyana ndi muyezo woyesera wa deta 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.Komabe, nambala yachisanu ndi chimodzi idzawonekera kokha pamene kuyesa kukana kukhudzidwa kukuchitika.Ngati sizichitika, padzakhala manambala 5 nthawi zonse.
Ngakhale mtundu wa 2016 wa en standard wakhala ukugwiritsidwa ntchito kwa zaka zopitirira zinayi, padakalipo mitundu yambiri yakale ya magolovesi pamsika.Magolovesi odulidwa omwe amatsimikiziridwa ndi ogwiritsa ntchito atsopano ndi akale onse ndi magolovesi oyenerera, koma tikulimbikitsidwa kuti tisankhe magolovesi odulidwa omwe ali ndi ma data 6 ndi zilembo za Chingerezi kuti asonyeze makhalidwe a magolovesi.
Kubwera kwa zida zambiri zatsopano, ndikofunikira kuti muzitha kuzigawa mosamalitsa kuti muwonetse kukana kodulidwa kwa magolovesi.Mu njira yatsopano yamagulu, palibe kusiyana pakati pa A1-A3 ndi maziko oyambirira a 1-3, koma A4-A9 ikufanizidwa ndi 4-5 yoyambirira, ndipo milingo 6 imagwiritsidwa ntchito kugawa magawo awiri oyambirira.Cut resistance imakhala ndi tsatanetsatane komanso kufotokozera.
M'mafotokozedwe a ANSI, osati kuchuluka kwa mawu okha, komanso miyezo yoyesera imakwezedwa.Poyambirira, muyezo wa ASTM F1790-05 unkagwiritsidwa ntchito poyesa, zomwe zimalola kuyesa zida za TDM-100 (zoyeserera zotchedwa TDM TEST) kapena zida za CPPT (zoyeserera zotchedwa COUP TEST).Tsopano ASTM F2992-15 imagwiritsidwa ntchito, ndipo TDM yokha ndiyololedwa.TEST imayesa mayeso.
Kodi pali kusiyana kotani pakati pa TDM TEST ndi COUP TEST?
COUP TEST imagwiritsa ntchito tsamba lozungulira lokhala ndi mphamvu yogwira ntchito ya 5 Copernicus kuti itembenuze kudula kwa laser pa zida zamagolovesi, pomwe TDM TEST imagwiritsa ntchito mutu wodula kukanikizira pamagetsi pamagetsi osiyanasiyana, mmbuyo ndi mtsogolo pamlingo wa 2.5 mm/s.laser kudula
Ngakhale mulingo watsopano wa EN 388 umafunika kugwiritsa ntchito COUP TEST ndi TDM TEST miyeso iwiri yoyeserera, koma pansi pa COUP TEST, ngati ndi zida zapamwamba zotsutsana ndi laser, tsamba lozungulira limatha kukhala losamveka ngati kudula kwa laser. Pambuyo pa maulendo 60, nsonga ya chida imakhala yosamveka pambuyo powerengera, ndipo TDM TEST ndiyofunikira.
Zindikirani kuti ngati TDM TEST ikuchitika pa magolovesi abwino kwambiri a laser kudula, ndiye kuti malo achiwiri a chitsanzo chotsimikizira akhoza kulembedwa ndi "X".Panthawiyi, kukana kodulidwa kumangosonyezedwa ndi kalata ya Chingerezi mu malo achisanu..
Ngati si za magolovesi abwino kwambiri osamva, sizingatheke kuti zida zopangira magolovu zisokoneze mutu wodula wa COUP TEST.Panthawiyi, TDM TEST ikhoza kusiyidwa, ndipo "X" imayikidwa pa malo achisanu a ndondomeko yotsimikizira.
Kwa magolovesi osadulira omwe amagwira ntchito bwino kwambiri, palibe TDM TEST kapena kuyesa kukana kwamphamvu sikunachitike.↑ Zopangira zamagolovu osagwira ntchito bwino kwambiri.TDM TEST idachitika, koma kuyesa kwa COUP ndi kukana kukana sikunachitike.
