Izandla zidlala indima ebalulekileyo kwinkqubo yomsebenzi wemveliso.Nangona kunjalo, izandla nazo ziyingxenye ezenzakaliswe ngokulula, zibalelwa malunga ne-25% yenani elipheleleyo lokulimala kwamashishini.Umlilo, ubushushu obuphezulu, umbane, iikhemikhali, iimpembelelo, ukusikwa, ukukrazuka, kunye nosulelo lunokubangela ubungozi ezandleni.Ukonzakala koomatshini okufana neempembelelo kunye nokusikeka kuxhaphakile, kodwa ukonzakala kombane kunye nokwenzakala ngemitha kubi kakhulu kwaye kunokukhokelela kukukhubazeka okanye nokufa.Ukuthintela izandla zabasebenzi ukuba zingonzakali ngexesha lomsebenzi, indima yeeglavu zokukhusela ibaluleke kakhulu.
Imigangatho yokuhlola iiglavu ezikhuselayo
NgoMatshi ka-2020, i-European Union yapapasha umgangatho omtsha:EN ISO 21420: 2019Iimfuno ngokubanzi kunye neendlela zokuvavanya iiglavu zokukhusela.Abavelisi beeglavu zokukhusela kufuneka baqinisekise ukuba izinto ezisetyenziselwa ukuvelisa iimveliso zabo azichaphazeli impilo yabaqhubi.Umgangatho omtsha we-EN ISO 21420 uthatha indawo ye-EN 420 umgangatho.Ukongeza, i-EN 388 yenye yemigangatho yaseYurophu yeeglavu zokukhusela kwimizi-mveliso.I-European Committee for Standardization (CEN) ivunyiwe inguqulo EN388: 2003 ngoJulayi 2, 2003. I-EN388: 2016 yakhululwa ngoNovemba 2016, ithatha indawo ye-EN388: 2003, kunye ne-supplementary version EN388: 2016 + A1: 2018 yahlaziywa18 kwi-20.
Imigangatho enxulumeneyo yeeglavu zokukhusela:
I-EN 388: 2016 umgangatho womatshini wokukhusela iiglavu
I-EN ISO 21420: Iimfuno ngokubanzi ze-2019 kunye neendlela zokuvavanya iiglavu ezikhuselayo
EN 407 Umgangatho womlilo kunye neeglavu ezikwaziyo ukumelana nobushushu
I-EN 374 Iimfuno zokumelana nokungena kweekhemikhali kwiiglavu ezikhuselayo
I-EN 511 Imigangatho yolawulo yeeglavu ezibandayo kunye nobushushu obuphantsi
I-EN 455 iiglavu ezikhuselayo zempembelelo kunye nokusikwa kokhuseleko
Iiglavu ezikhuselayoindlela yokuhlola
Ukuze kukhuselwe ukhuseleko lwabathengi kwaye kuthintelwe ilahleko kubathengisi okubangelwa kukukhumbula ngenxa yemicimbi yobulunga bemveliso, zonke iiglavu ezikhuselayo ezithunyelwa kumazwe e-EU kufuneka ziphumelele olu hlolo lulandelayo:
1. Uvavanyo lokusebenza koomatshini kwindawo

Uvavanyo lokusika lwe-TDM lusebenzisa i-blade ukusika izinto zesundu zeglavu ngesantya esingaguqukiyo.Ivavanya ubude bokuhamba kwe-blade xa inqumla isampuli phantsi kwemithwalo eyahlukeneyo.Isebenzisa iifomyula zemathematika ezichanekileyo ukubala (i-slope) ukufumana umthamo wamandla okufuneka usetyenziswe ukwenza i-blade ihambe i-20mm.Sika isampuli.
Olu vavanyo yinto esanda kufakwa kwi-EN388: inguqulo ye-2016.Inqanaba lesiphumo lichazwa njenge-AF, kwaye F lelona nqanaba liphezulu.Xa kuthelekiswa ne-EN 388: uvavanyo lwe-coupe lwe-2003, uvavanyo lwe-TDM lunokubonelela ngokuchaneka ngakumbi kwezalathi zokusebenza zokunqanda ukusebenza.
5.6 Ukuchasana kwempembelelo (EN 13594)
Umlingiswa wesithandathu umele ukhuseleko lwempembelelo, oluluvavanyo lokuzikhethela.Ukuba iiglavu zivavanyelwa ukhuseleko lwempembelelo, olu lwazi lunikwa ngunobumba P njengophawu lwesithandathu nolokugqibela.Ngaphandle kwe-P, iglavu ayinalo ukhuseleko lwempembelelo.
2. Ukuhlolwa kwembonakaloyeeglavu zokukhusela
-Igama lomenzi
- Iiglavu kunye nobukhulu
- CE isiqinisekiso uphawu
- EN umzobo welogo eqhelekileyo
Ezi mpawu kufuneka zihlale zifundeka kubo bonke ubomi beglavu
3. Iiglavu ezikhuselayoukuhlolwa kokupakishwa
- Igama kunye nedilesi yomenzi okanye ummeli
- Iiglavu kunye nobukhulu
- CE uphawu
- Yinkqubo ekujoliswe kuyo/inqanaba losetyenziso, umz. "kumngcipheko omncinci kuphela"
- Ukuba iglavu ibonelela kuphela ukhuseleko kwindawo ethile yesandla, oku kufuneka kuchazwe, umz. "ukukhuselwa kwesundu kuphela"
4. Iiglavu ezikhuselayo ziza nemiyalelo okanye iincwadi zokusebenza
- Igama kunye nedilesi yomenzi okanye ummeli
- Igama leglove

- Igama kunye nedilesi yequmrhu lezatifiketi eliqinisekise imveliso
- Imigangatho esisiseko
5. Iimfuno zokungabi nabungoziyeeglavu zokukhusela
- Iiglavu kufuneka zinike ukhuseleko oluphezulu;
- Ukuba kukho i-seams kwiglavu, ukusebenza kweglavu akufanele kuncitshiswe;
- ixabiso le-pH kufuneka libe phakathi kwe-3.5 kunye ne-9.5;
- Umxholo weChromium (VI) kufuneka ube ngaphantsi kwexabiso lokubona (<3ppm);
- Iiglavu zerubha zendalo kufuneka zivavanywe kwiiprotheni ezikhutshwayo ukuqinisekisa ukuba azibangeli ukuchasana nokwaliwa kulowo uzinxibileyo;
- Ukuba imiyalelo yokucoca inikwe, amanqanaba okusebenza makangancitshiswa nasemva kwenani eliphezulu lokuhlambela.
I-EN 388: umgangatho we-2016 unokunceda abasebenzi ukuba babone ukuba zeziphi iiglavu ezinomgangatho ofanelekileyo wokukhusela kwiingozi zoomatshini kwindawo yokusebenza.Ngokomzekelo, abasebenzi bokwakha banokudibana nomngcipheko wokukrazula kwaye kufuneka bakhethe iiglavu ezinokumelana nokunxiba okuphezulu, ngelixa abasebenzi besinyithi kufuneka bazikhusele ekusikeni ukulimala kwizixhobo zokusika okanye imikrwelo evela kwimiphetho yentsimbi ebukhali, efuna ukukhetha iiglavu nge umgangatho ophezulu wokumelana nokusika.Iiglavu.
