Okwangoku, kukho iintlobo ezininzi zeeglavu ezisikiweyo kwimarike.Ingaba umgangatho weeglavu ezisikiweyo ulungile?Yeyiphi ekungekho lula ukuyigqiba?Indlela yokukhetha ukuphepha ukhetho olungalunganga?
Ezinye iiglavu ezisikwayo kwimarike zinegama elithi “CE” elishicilelwe ngasemva.Ngaba u-“CE” uthetha uhlobo oluthile lwesatifikethi?
Uphawu lwe "CE" sisiqinisekiso sokhuseleko, esithathwa njenge-visa yokundwendwela abavelisi ukuba bavule kwaye bangene kwimarike yokuthengisa yaseYurophu.I-CE ithetha umanyano lwaseYurophu (CONFORMITE EUROPEENNE).Ekuqaleni i-CE yayiyintsingiselo yomgangatho waseYurophu, ke ukongeza kumgangatho ween yeeglavu ezikwaziyo ukusikwa, zeziphi ezinye iinkcukacha ekufuneka zilandelwe?
Iiglavu zokukhusela ukhuseleko lokukhusela ukulimala kwezixhobo zoomatshini kufuneka zihambelane ne-EN 388, inguqu yakutshanje yinombolo yenguqulo ye-2016, kunye ne-American standard ANSI / ISEA 105, inguqulo yakamuva nayo i-2016.
Kule mibini inkcazo, ukubonakaliswa kwenqanaba lokumelana nokusika kuyahluka.
Iiglavu ezikwaziyo ukusika eziqinisekisiweyo ngomgangatho ziya kuba nepateni enkulu yekhaka elinamagama "EN 388" phezulu.Iidijithi ezi-4 okanye ezi-6 zedatha kunye noonobumba besiNgesi ezantsi 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.
Amanani ama-4 okuqala anentsingiselo efanayo, "ukumelana nokunxiba", "ukunqanda ukusika", "ukuqina", kunye "nokumelana nokuhlatywa".Inkulu idatha, ngcono iimpawu.
Ileta yesihlanu yesiNgesi iphinda ibonise "ukusika ukuchasana", kodwa umgangatho wokuvavanya uhluke kumgangatho wokuvavanya wedatha yesibini, kwaye indlela yokubonisa inqanaba lokumelana nokusika likwahluke, okuya kuchazwa ngokucacileyo kamva.
Ileta yesithandathu yesiNgesi ibonisa "ukuchasana kwempembelelo", ekwaboniswa ngeeleta zesiNgesi.Nangona kunjalo, idijithi yesithandathu iya kubonakala kuphela xa uvavanyo lokumelana nempembelelo lwenziwa.Ukuba ayiqhutywa, kuya kuhlala kukho amanani ama-5.
Nangona inguqu ye-2016 ye-en standard isetyenziswe ngaphezu kweminyaka emine, kusekho iinguqulelo ezininzi ezindala zeeglavu kwiimarike.Iiglavu ezinqambileyo ezingqinisiswe ngabasebenzisi abatsha kunye nabadala zonke ziyiiglavu ezifanelekileyo, kodwa kucetyiswa ngamandla ukuba ukhethe iiglavu ezinqambileyo kunye nedatha yeedijithi ezi-6 kunye neeleta zesiNgesi ukubonisa iimpawu zeeglavu.
Ngokufika kwenani elikhulu lezinto ezitsha, kuyimfuneko ukukwazi ukuhlula ngokucokisekileyo ukubonisa ukuxhathisa okusikiwe kweeglavu.Kwindlela entsha yokuhlela, akukho mahluko phakathi kwe-A1-A3 kunye nesiseko se-1-3 sokuqala, kodwa i-A4-A9 ithelekiswa ne-4-5 yasekuqaleni, kwaye amanqanaba ama-6 asetyenziselwa ukwahlula amanqanaba amabini okuqala.Ukuchasana nokusika kuqhuba ulwahlulo oluneenkcukacha kunye nokubonakalisa.
Kwinkcazo ye-ANSI, kungekhona kuphela inqanaba lokuvakalisa, kodwa kunye nemigangatho yokuvavanya iphuculwe.Ekuqaleni, umgangatho we-ASTM F1790-05 wawusetyenziselwa uvavanyo, oluvumela ukuvavanywa kwizixhobo ze-TDM-100 (umgangatho wovavanyo obizwa ngokuba yi-TDM TEST) okanye izixhobo ze-CPPT (umgangatho wovavanyo obizwa ngokuba yi-COUP TEST).Ngoku i-ASTM F2992-15 isetyenziswa, kwaye kuphela i-TDM evumelekileyo.UVAVANYO luqhuba uvavanyo.
Yintoni umahluko phakathi kovavanyo lwe-TDM kunye novavanyo lwe-COUP?
I-COUP TEST isebenzisa i-circular blade kunye noxinzelelo olusebenzayo lwe-5 Copernicus ukuguqula ukusika kwe-laser kwi-glove material, ngelixa i-TDM TEST isebenzisa intloko ye-cutter ukucinezela impahla yeglavu kwixinzelelo lokusebenza eyahlukileyo, ngasemva nangaphandle kwinqanaba le-2.5 mm/s.ukusika laser
Nangona umgangatho omtsha we-EN 388 ufuna ukusetyenziswa kwe-COUP TEST kunye ne-TDM TEST imigangatho emibini yovavanyo, kodwa phantsi kwe-COUP TEST, ukuba yinto ephezulu yokusebenza kwe-anti-laser yokusika izinto eziluhlaza, i-blade ejikelezayo inokuthi ibe buthuntu, ukuba i-laser cut. Emva kwemijikelo engama-60, incam yesixhobo iba buthuntu emva kokubala, kwaye uvavanyo lwe-TDM lunyanzelekile.
Kufuneka kuqatshelwe ukuba ukuba uvavanyo lwe-TDM lwenziwa kule glavu igqwesileyo yokusika i-laser, ke indawo yesibini yepateni yokuqinisekisa ingabhalwa nge "X".Ngeli xesha, ukuchasana kokusika kuboniswa kuphela ngonobumba wesiNgesi kwindawo yesihlanu..
Ukuba ayizizo iiglavu ezigqwesileyo ezisikiweyo ezixhathisayo, akunakufane kwenzeke ukuba izixhobo ezikrwada zeeglavu zibe buthuntu intloko yomsiki we-COUP TEST.Ngeli xesha, i-TEST ye-TDM inokushiywa, kwaye "X" ibekwe kwindawo yesihlanu yepateni yokuqinisekisa.
Kwiiglavu ezingasikwanga ngokusebenza okugqwesileyo, akukho TEST ye-TDM okanye uvavanyo lokumelana nempembelelo lwenziwe.↑ Izinto ezikrwada zeeglavu ezisikiweyo ezisebenza ngokugqwesileyo.UVAVANYO lwe-TDM lwenziwa, kodwa uvavanyo lwe-COUP kunye novavanyo lokumelana neempembelelo aluzange lwenziwe.
