Parizvino, kune akawanda marudzi ekucheka-resistant magirovhosi pamusika.Hunhu hwemagirovhosi asingadzivirirwe hwakanaka here?Ndeipi isiri nyore kupera?Nzira yekusarudza sei kudzivisa kusarudzwa kusina kunaka?
Mamwe magirovhosi asingadzivirirwe pamusika ane izwi rekuti "CE" rakadhindwa kudivi reshure.Ko “CE” inoreva rudzi rwakati rwechitupa here?
Iyo "CE" mucherechedzo ndeyekuchengetedza certification, iyo inoonekwa sepasipoti vhiza kuti vagadziri vavhure uye vapinde mumusika wekutengesa weEuropean.CE zvinoreva kubatana kweEurope (CONFORMITE EUROPEENNE).Pakutanga CE ndiko kwaireva chiyero cheEuropean, saka pamusoro peiyo en standard yeasingadzivirirwe magirovhosi, ndezvipi zvimwe zvinongedzo zvinofanirwa kuteverwa?
Magurovhosi ekudzivirira ekudzivirira kukuvara kwemuchina anofanira kutevedzera EN 388, iyo yazvino vhezheni ndiyo 2016 vhezheni nhamba, uye American standard ANSI/ISEA 105, yazvino vhezheni zvakare 2016.
Mune izvi zviviri zvakatsanangurwa, kutaura kweyero yekucheka kushorwa kwakasiyana.
Magurovhosi anodzivirirwa akasimbiswa ne en standard achave neshield pateni yakakura ine mazwi "EN 388" kumusoro.Iwo mana kana matanhatu manhamba edata uye mavara echiRungu pazasi peiyo hofori shield pateni.Kana iri 6-manhamba data uye mavara echiRungu, inoratidza kuti itsva EN 388: 2016 tsanangudzo inoshandiswa, uye kana iri 4-manhamba, inoratidza kuti yekare 2003 tsanangudzo inoshandiswa.
Mavara mana ekutanga ane chirevo chimwe chete, chinoti "kupfeka kuramba", "cut resistance", "resilience", uye "puncture resistance".Iyo yakakura data, zviri nani maitiro.
Tsamba yechishanu yeChirungu inoratidzawo "cut resistance", asi chiyero chekuedza chakasiyana nechiyero chekuedza chechipiri data, uye nzira yekuratidza kuchekwa kwekudzivirira chiyero yakasiyanawo, iyo inozotsanangurwa zvakadzama gare gare.
Tsamba yechitanhatu yeChirungu inoratidza "impact resistance", iyo inoratidzirwawo nemavara eChirungu.Nekudaro, iyo yechitanhatu digit inongoonekwa chete kana maitiro ekupikisa bvunzo aitwa.Kana ikasaitwa, pachagara paine manhamba mashanu.
Kunyangwe iyo 2016 vhezheni yeen standard yakashandiswa kweanopfuura makore mana, kuchine akawanda ekare mavhezheni egurovhosi pamusika.Magurovhosi akachekwa akasimbiswa nevashandisi vatsva uye ekare ese magirovhosi anokodzera, asi zvinokurudzirwa zvakanyanya kusarudza magurovhosi asingadzivirirwe ane 6-digit data uye mabhii echiRungu kuratidza maitiro egirovhosi.
Nekuuya kwenhamba huru yezvinhu zvitsva, zvinodikanwa kuti ukwanise kuaronga zvine hunyoro kuratidza kuchekwa kwekupokana kwemagurovhosi.Munzira itsva yekuisa, hapana mutsauko pakati peA1-A3 uye yekutanga 1-3 hwaro, asi A4-A9 inofananidzwa neyekutanga 4-5, uye nhanho nhanhatu dzinoshandiswa kupatsanura matanho maviri ekutanga.Cheka kuramba inoburitsa yakanyatso kurongeka uye kutaura.
Mune iyo ANSI yakatarwa, kwete chete nhanho yekutaura, asiwo miyero yekuyedza inokwidziridzwa.Pakutanga, iyo ASTM F1790-05 yakajairwa yaishandiswa pakuyedza, iyo yaibvumira kuyedzwa pamidziyo yeTDM-100 (yeyeyedzo inonzi TDM TEST) kana CPPT midziyo (yekuyedza standard inonzi COUP TEST).Iye zvino ASTM F2992-15 inoshandiswa, uye chete TDM inobvumirwa.TEST inoita bvunzo.
Ndeupi musiyano uripo pakati peTDM TEST neCOUP TEST?
COUP TEST inoshandisa denderedzwa blade ine simba rekushanda re5 Copernicus kufambisa laser yekucheka pane girovhosi zvinhu, nepo TDM TEST inoshandisa musoro wekucheka kudzvanya pane girovhosi pane imwe kushanda kwakasiyana, kumashure nekudzoka pamwero we2.5. mm/s.laser kucheka
Kunyangwe iyo itsva EN 388 yakajairwa ichida kushandiswa kweCOUP TEST uye TDM TEST mazinga maviri ebvunzo, asi pasi peCOUP TEST, kana iri yepamusoro-inoshanda anti-laser yekucheka mbishi zvinhu, blade yedenderedzwa inogona kugomara, kana laser kucheka. Mushure menguva makumi matanhatu, iyo tepi yekushandisa inova isina kujeka mushure mekuverenga, uye TDM TEST inosungirwa.
Izvo zvinofanirwa kucherechedzwa kuti kana TDM TEST ikaitwa kune iyi yakanakisa laser yekucheka inodzivirira girovhosi, ipapo nzvimbo yechipiri yeiyo yekusimbisa pateni inogona kunyorwa ne "X".Panguva ino, kushorwa kwekucheka kunongoratidzwa chete netsamba yeChirungu munzvimbo yechishanu..
Kana isiri yeakanakisa kucheka-inodzivirira magirovhosi, hazvigoneke kuti zvigadzirwa zvemagirovhosi zvigomedzeresa musoro wekucheka weCOUP TEST.Panguva ino, TDM TEST inogona kusiiwa, uye "X" inoiswa pachinzvimbo chechishanu cheiyo verification pateni.
Kune asiri-kucheka magurovhosi ane mashandiro akanaka, kana TDM TEST kana kukanganisa kuramba kuyerwa kwakaitwa.↑ Iyo mbishi yeakachekwa-anodzivirira magirovhosi ane mashandiro akanaka.TDM TEST yakaitwa, asi COUP TEST uye maitiro ekuramba bvunzo hazvina kuitwa.
