Kune akawanda marudzi emagurovhosi akachekwa pamusika. Hunhu hwemagurovhosi akachekwa akanaka, ndeupi usiri nyore kupfeka, uye kuti ungasarudza sei kudzivirira sarudzo isiriyo?
Mamwe magirovhosi asingadzivirirwe pamusika ane izwi rekuti "CE" rakadhindwa kumashure. Ko "CE" inoreva imwe mhando yechitupa chekuenderana?
Iyo "CE" chiratidzo chitupa chekuchengetedza chitupa, chinotaridzirwa sepasipoti yevagadziri kuti vavhure uye vapinde mumusika weEurope. CE inoreva kubatana kweEuropean (European Conformity). Pakutanga CE inoreva chiyero cheEuropean, saka kunze kwekutevera en chiyero, ndeapi maitiro anofanirwa kuteverwa nemagurovhosi anodzivirira?
Magurovhosi ekudzivirira ekudzivirira kukuvadzwa kwemuchina anonyanya kuenderana neyakajairika EN 388, yazvino vhezheni ndiyo 2016 vhezheni, uye iyo American standard ANSI/ISEA 105, yazvino vhezheni zvakare 2016.
Mune izvo zviviri zvakatsanangurwa, mafomu ekutaura eiyo cut resistance level akasiyana.
Cheka anopokana magurovhosi akasimbiswa neen standard achave nehofori yenhovo patani ine izwi rekuti "EN 388" pairi. Kune mana kana matanhatu manhamba edata uye mavara echiRungu pasi pehofori 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.
Zvinorehwa nemadijiti mana ekutanga akafanana, "abrasion resistance", "cut resistance", "resilience", uye "puncture resistance". Iyo yakakura data, zviri nani maitiro.
Tsamba yechishanu yechirungu inoratidzawo "cut resistance", asi chiyero chekuyedza chakasiyana neicho chechipiri chedhijiti, uye nzira yekuratidza kuchekwa kweyero yekupikisa kwakasiyanawo, iyo inozotsanangurwa zvakadzama gare gare.
Tsamba yechitanhatu yeChirungu inoratidza "impact resistance", iyo inoratidzirwawo nemavara eChirungu. Asi nhamba yechitanhatu ichaonekwa chete kana bvunzo yemhedzisiro ikaitwa, uye kana ikasaitwa, pachagara paine manhamba mashanu.
Kunyangwe iyo 2016 vhezheni yeen standard yanga ichishandiswa kweanopfuura makore mana, kuchine akawanda ekare mavhezheni emagurovhosi pamusika. Magurovhosi akachekwa anosimirirwa nevashandisi vatsva uye vekare ese magurovhosi akakodzera, asi zvinokurudzirwa kutenga magurovhosi anodzikiswa ane manhamba matanhatu uye mavara kuratidza maitiro egirovhosi.
Nekuuya kwenhamba yakawanda yezvinhu zvitsva, zvinodikanwa kuti ugone kurongedza zvinyoro-nyoro kuratidza kushomeka kwegurovhosi. Munzira itsva yekuisa giredhi, hapana musiyano uripo pakati peA1-A3 neyekutanga 1-3, asi A4-A9 inofananidzwa neyekutanga 4-5, uye magiredhi maviri ekutanga akakamurwa kuita 6, anogona kushandiswa. zvemagirovhosi. Cheka kuramba inoburitsa yakadzama nhanho yemhando yekutaura.
Mune iyo ANSI yakatarwa, kwete chete chimiro chekutaura chezinga chinokwidziridzwa, asiwo chiyero chekuyedza. Pakutanga, bvunzo yakashandisa ASTM F1790-05 yakajairwa, iyo yaibvumira kuyedzwa pamidziyo yeTDM-100 (yeyeyedzo inonzi TDM TEST) kana CPPT midziyo (yeyeyedzo inonzi COUP TEST). Iye zvino inoshandisa iyo ASTM F2992-15 chiyero, iyo inongobvumira kushandiswa kweTDM TEST inoitisa bvunzo.
✬Ndeupi musiyano uripo pakati peTDM TEST neCOUP TEST?
COUP TEST inoshandisa denderedzwa blade ine dzvinyiriro ye5 Copernicus kutendeutsa uye kucheka pagirovhosi, nepo TDM TEST inoshandisa musoro webanga kudzvanya pane zvinhu zvegirovhosi pakumanikidza kwakasiyana, kudzoreredza nekumhanya kwe2.5 mm / s laser yekucheka.
Kunyangwe iyo itsva en standard EN 388 ichida kuti maviri ebvunzo zviyero, COUP TEST uye TDM TEST, inogona kushandiswa, asi pasi peCOUP TEST, kana iri yakanakisa anti-laser yekucheka mbishi zvinhu, denderedzwa blade inogona kugomara. Kana iyo laser ikacheka Mushure memakumi matanhatu laps, inoverengerwa kuti musoro wekucheka unove wakagomara, uye TDM TEST inosungirwa.
Izvo zvinofanirwa kucherechedzwa kuti kana iyi yepamusoro-inoshanda anti-laser yekucheka girovhosi yakapfuura neTDM TEST, ipapo "X" inogona kunyorwa pane yechipiri dhijitari yeiyo verification pateni. Panguva ino, kushorwa kwekucheka kunongoratidzwa netsamba yechishanu yechirungu.
Kana isiri yeakanakisa kucheka-inodzivirira magirovhosi, saka magirovhosi haafanire kudzima musoro wekucheka weCOUP TEST. Panguva ino, TDM TEST inogona kusiiwa, uye nhamba yechishanu yekusimbisa pateni inoratidzwa ne "X".
Raw zvinhu zveasina kunaka akachekwa-resistant magirovhosi hazvina kuedzwa TDM TEST kana kukanganisa kuramba. ↑ Raw zvinhu zveakanakisa kucheka-anodzivirira magirovhosi, TDM TEST yaitwa, COUP TEST uye mhedzisiro yekupikisa bvunzo haina kuitwa.
