1. Isingeniso Esijwayelekile

I-EN 10305-5 iyisigaba esizinikele ochungechungeni olujwayelekile lwamashubhu ensimbi aqondile aseYurophu. Isihloko sayo esigcwele sithi "Amashubhu ensimbi aqondile—Ingxenye 5: Izimo zokulethwa kobuchwepheshe zamashubhu ensimbi aqondile aqediwe ngokubandayo." Le nqubo ithuthukiswe yiKomidi LaseYurophu Lokumisa (i-CEN) futhi isebenza njengenye yezindlela zobuchwepheshe eziyinhloko zokukhiqizwa nokwamukelwa kwamashubhu ensimbi anomumo oqondile kulo lonke elase-EU.

 Leli zinga lisebenza kumashubhu asikwele nawayindilinga aqediwe ukubanda anobukhulu bodonga obungu-6mm kanye nobubanzi obuncane bangaphandle obungu-4mm. Le mikhiqizo ibonakala ngokunemba okuphezulu, ikhwalithi ephezulu yendawo, kanye nezakhiwo ezihambisanayo zemishini, eziwabeka njengemikhiqizo yeshubhu yensimbi enenani eliphezulu.

 2. Izidingo Zobuchwepheshe Eziyinhloko

2.1 Amabanga Ensimbi

 Indinganiso ichaza amamaki amabili ayinhloko ensimbi:

 I-E235: Izinga eliyisisekelo linikeza ukusebenza okulinganiselayo, ukushibilika okuhle, kanye nekhono elihle kakhulu lokwenza ubanda. Leli izinga elisetshenziswa kakhulu emakethe.

 I-E355: Izinga lamandla aphezulu elinezinkomba zamandla ezithuthukisiwe kanye nokuqina komthelela kune-E235, elifanele ukusetshenziswa okunzima kakhulu ekuthwaleni umthwalo.

 2.2 Ukwakheka Kwamakhemikhali (E235 njengeNkomba)

 Isici C Si Mn P S

Okuqukethwe (%) 0.17-0.22 0.10-0.35 0.40-0.80 ≤0.035 ≤0.035

2.3 Izakhiwo Zemishini (E235 Njengereferensi)

 Amandla Okudonsa: 440-540 MPa

 Amandla Okukhiqiza:≥290 MPa

 Ukwandiswa Kwamaphesenti:≥12%

 2.4 Izimo Zokulethwa

 Indinganiso ivumela izimo eziningi zokulethwa, kuye ngesivumelwano phakathi komhlinzeki nomthengi:

 I-BK (Iqinile eliqediwe ngokubandayo): Lihlinzekwa ngaphandle kokwelashwa ngokushisa, ligcina isimo esiqinile ngemva kokusebenza ngokubandayo

 I-BKW (Esebenza kancane ebandayo): Ukusebenza okubandayo okuncane okuhlala kusesimweni esihle

 I-GBK (Efakwe i-Annealed): Ifakwe i-Annealed ngemva kokusebenza ngokubandayo

 I-NBK (Ejwayelekile): Ihlinzekwa isesimweni esijwayelekile

 3. Izimakethe Zohlelo Lokusebenza

Amashubhu ensimbi e-EN 10305-5 asetshenziswa kakhulu ekusetshenzisweni kokukhiqiza ngokunemba. Ukusetshenziswa okujwayelekile kufaka phakathi:

 Izinhlelo Zokudlulisa Uketshezi: Amasekethe kawoyela we-hydraulic emishini yokwakha kanye namathuluzi omshini, adinga ubukhulu obuqondile kanye nezindawo zangaphakathi ezibushelelezi ukuqinisekisa ukusebenza kahle kokudlulisa uketshezi.

 Izinhlelo Zokulawula Umoya: Imigqa yokulethwa komoya ecindezelwe enezidingo eziqinile zokuqinisekisa ukunemba kokulingana kokuvala.

 Ukukhiqizwa Kwezingxenye Zezimoto: Izintambo zokujova uphethiloli ezinomfutho ophezulu kanye namapayipi esistimu yokuqondisa amandla—zombili izingxenye zokuphepha ezibalulekile.

 Umshini Ojwayelekile Wokwenza Imishini: Usetshenziswa njengezikhala zemikhono yomgodi eqondile, imikhono yokuqondisa, kanye nezisekelo zesakhiwo zemisebenzi elandelayo yomshini wokwenza imishini.

 Ukuhlanganiswa Kwemishini Yezimboni: Imikhono yezinzwa, amashubhu ezinsimbi, kanye nezinhlelo zokusebenza ezifanayo zokunemba.

 4. Izimboni Ezifanele

Imikhiqizo engaphansi kwe-EN 10305-5 ngokuyinhloko ikhonza imikhakha elandelayo yezimboni:

Ukukhiqizwa Kwezimoto Nezentengiselwano

Imishini Yokwakha Nemishini Yezolimo

Ukukhiqizwa Kwezingxenye Ze-Hydraulic kanye Ne-Pneumatic

Imishini Ejwayelekile kanye Nokusebenza Ngokunemba

Ukuhlanganiswa Kwezinhlelo Zokuzenzakalela Zezimboni kanye Nokulawula

5. Ukuma Kwemakethe kanye Nenani

I-EN 10305-5 ayiweli esigabeni samashubhu ajwayelekile esakhiwo. Esikhundleni salokho, ihlose imakethe yamashubhu ensimbi akhethekile anokunemba okuphezulu, ukuthembeka okuphezulu, kanye nenani eliphakeme. Amanani ayo ayinhloko afaka:

Ukunikeza amakhasimende izinkomba zokusebenza ezibikezelwayo neziqinisekisiwe kanye nokubekezelelana okubonakalayo

Ukunciphisa imfucuza yezinto ezibonakalayo kanye nezindleko zokulungisa kabusha kumakhasimende angaphansi komfula ngesikhathi sezinqubo zomshini nokuhlanganisa

Ukuqinisekisa ukusebenza okuzinzile kwesikhathi eside kwemishini yokusetshenziswa kokugcina ngaphansi kwezimo zokusebenza ezicindezela kakhulu nezisebenza ngomjikelezo ophezulu

Kwabathumeli bamashubhu ensimbi baseShayina, i-EN 10305-5 ingenye yezindinganiso ezivamile zokuqala zokufinyelela uchungechunge lokuhlinzeka ngokukhiqiza okunembile okuphezulu lwaseYurophu. Amandla abonisiwe okuhlinzeka ngemikhiqizo ngokuhambisana naleli zinga asebenza njengesiqinisekiso esibalulekile sokuthola ukuqashelwa kumakhasimende aseYurophu asezingeni eliphakathi kuya kweliphezulu ezingxenyeni zezimoto, izinhlelo ze-hydraulic, kanye nemikhakha ehlobene.
