Kukho iintlobo ezininzi zeeglavu ezisikiweyo kwimarike. Ngaba umgangatho weeglavu ezixhathisayo ezisikiweyo zilungile, yiyiphi enye engelula ukuyinxiba, kunye nendlela yokukhetha ukuphepha ukhetho olungalunganga?
Ezinye iiglavu ezinganyangekiyo kwimarike zinegama elithi "CE" liprintwe ngasemva. Ngaba "CE" ithetha uhlobo oluthile lwesatifikethi sokuthotyelwa?
Inqaku elithi "CE" sisiqinisekiso sokhuseleko, esithathwa njengepaspoti yokuba abavelisi bavule kwaye bangene kwimarike yaseYurophu. CE kuthetha umanyano lwaseYurophu (European Conformity). Ekuqaleni i-CE ithetha umgangatho waseYurophu, ke ngaphandle kokulandela umgangatho, yeyiphi imimiselo ekufuneka ilandelwe ziiglavu ezixhathisayo?
Iiglavu ezikhuselayo zokukhusela umonakalo womatshini ngokuyinhloko zihambelana ne-en standard EN 388, inguqu yakutshanje yinguqulo ye-2016, kunye ne-American standard ANSI / ISEA 105, inguqulo yakamuva nayo i-2016.
Kwiinkcukacha ezimbini, iifom zokubonakaliswa kwinqanaba lokumelana nokusikwa zihlukile.
Sika iiglavu ezixhathisayo ezingqinisiswe ngumgangatho we-en ziya kuba nepateni enkulu yesihlangu enegama elithi "EN 388" kuyo. Kukho iidijithi ezi-4 okanye ezi-6 zedatha kunye noonobumba besiNgesi phantsi kwepateni enkulu yekhaka. Ukuba i-6-digit data kunye neeleta zesiNgesi, ibonisa ukuba i-EN 388: 2016 entsha inkcazo isetyenzisiweyo, kwaye ukuba i-4-digit, ibonisa ukuba i-2003 endala i-specification isetyenziswa.
Iintsingiselo zedijithi ezi-4 zokuqala ziyafana, "ziyi-abrasion resistance", "cut resistance", "relience", kunye "ne-puncture resistance". Inkulu idatha, ngcono iimpawu.
Ileta yesihlanu yesiNgesi iphinda ibonise "ukuchasana nokusika", kodwa umgangatho wokuvavanya uhlukile kulowo wesibini wedijithi, kwaye indlela yokubonisa inqanaba lokumelana nokusika likwahlukile, okuya kuchazwa ngokucacileyo kamva.
Ileta yesithandathu yesiNgesi ibonisa "ukuchasana kwempembelelo", ekwaboniswa ngeeleta zesiNgesi. Kodwa idijithi yesithandathu iya kubonakala kuphela ukuba uvavanyo lwempembelelo luyenziwa, kwaye ukuba aluqhutywa, kuya kuhlala kukho amadijithi ama-5.
Nangona inguqulo ye-2016 ye-en standard sele isetyenziswe ngaphezu kweminyaka emine, kusekho ezininzi iinguqulelo zakudala zeeglavu kwiimarike. Iiglavu ezisikiweyo eziqinisekisiweyo ngabasebenzisi abatsha kunye nabadala zonke ziyiiglavu ezifanelekileyo, kodwa kucetyiswa ngakumbi ukuthenga iiglavu ezisikiweyo ezinamadijithi ama-6 kunye noonobumba ukubonisa iimpawu zeglavu.
Ngokufika kwenani elikhulu lezinto ezitsha, kuyimfuneko ukukwazi ukuhleleka ngokufihlakeleyo ukubonisa ukuchasana nokunqunyulwa kweeglavu. Kwindlela entsha yokuhlelwa kwebakala, akukho mahluko phakathi kwe-A1-A3 kunye ne-1-3 yentsusa, kodwa i-A4-A9 ithelekiswa neyokuqala 4-5, kwaye amabanga amabini okuqala ahlulwe abe ngamabakala ama-6, anokusetyenziswa. iiglavu. Ukumelana nokusika kukhupha inkcazo yolwahlulo olunenkcukacha.
Kwinkcazo ye-ANSI, kungekhona kuphela indlela yokubonakalisa inqanaba eliphuculweyo, kodwa kunye nomgangatho wokuvavanya. Ekuqaleni, uvavanyo lwalusebenzisa umgangatho we-ASTM F1790-05, owavumela ukuvavanywa kwizixhobo ze-TDM-100 (umgangatho wokuvavanya ubizwa ngokuba yi-TDM TEST) okanye izixhobo ze-CPPT (umgangatho wovavanyo ubizwa ngokuba yi-COUP TEST). Ngoku isebenzisa umgangatho we-ASTM F2992-15, ovumela kuphela ukusetyenziswa kwe-TDM TEST kuqhuba uvavanyo.
✬Yintoni umahluko phakathi kovavanyo lwe-TDM kunye novavanyo lwe-COUP?
I-COUP TEST isebenzisa i-circular blade kunye noxinzelelo lwe-5 Copernicus ukujika kunye nokusika izinto zeglavu, ngelixa i-TDM TEST isebenzisa intloko yomese ukucinezela izinto zeglavu kwiingcinezelo ezahlukeneyo, zibuyisela ngesantya se-2.5 mm / s laser cutting
Nangona entsha en standard EN 388 ifuna ukuba imigangatho yovavanyo emibini, CUP TEST kunye TDM TEST, ingasetyenziswa, kodwa phantsi kovavanyo lwe-COUP, ukuba yinto egqwesileyo ye-anti-laser yokusika izinto eziluhlaza, iblade ejikelezayo inokuthi ibe buthuntu. Ukuba i-laser iyasika Emva kwemijikelo engama-60, kubalwa ukuba intloko yokusika iba buthuntu, kwaye UVAVANYO lwe-TDM lunyanzelekile.
Kufuneka kuqatshelwe ukuba ukuba le glove ye-anti-laser cutting cut-performance ephezulu ifumene i-TDM TEST, ngoko "X" ingabhalwa kwidijithi yesibini yepateni yokuqinisekisa. Ngeli xesha, ukuchasana kokunqunyulwa kuboniswa kuphela ngombhalo wesihlanu wesiNgesi.
Ukuba ayizizo iiglavu ezigqwesileyo ezisikiweyo ezixhathisayo, ngoko ke imathiriyeli yeglavu ayinakwenzeka ukuba ibe buthuntu intloko yomsiki we-COUP TEST. Ngeli xesha, i-TDM TEST inokushiywa, kwaye idijithi yesihlanu yepateni yokuqinisekisa iboniswa ngu "X".
Imathiriyeli ekrwada yeeglavu ezingagqwekiyo ezisikiweyo azikavavanyelwa UVAVANYO lwe-TDM okanye ukuxhathisa impembelelo. ↑ Imathiriyeli ekrwada yeeglavu ezigqwesileyo ezisikiweyo, UVAVANYO lwe-TDM luye lwaqhutywa, UVAVANYO lwe-COUP kunye novavanyo lokumelana nempembelelo alwenziwanga.
