Izikhundla ze-DIN ezindala nezintsha

Ngokuhamba kweminyaka, izindinganiso eziningi ze-DIN zahlanganiswa namazinga e-ISO, kanjalo futhi zaba yingxenye yezindinganiso ze-EN. Ngosizo lokubuyekezwa kwamazinga aseYurophu amazinga athile e-DIN ahoxisiwe futhi athathelwa indawo yi-DIN ISO EN kanye ne-DIN EN.
Amazinga asetshenziswe esikhathini esidlule njenge-DIN 17121, DIN 1629, DIN 2448 kanye ne-DIN 17175 athathelwe indawo kakhulu ama-Euronorms. Ama-Euronorm ahlukanisa ngokucacile indawo yepayipi esetshenziswayo. Ngenxa yalokho amazinga ahlukene manje akhona amapayipi asetshenziswa njengezinto zokwakha, amapayipi noma izicelo zobunjiniyela bemishini.
Lo mehluko wawungacace kangako esikhathini esidlule. Isibonelo, ikhwalithi endala ye-St.52.0 yathathwa ezingeni le-DIN 1629 elalihloselwe amasistimu wamapayipi kanye nezicelo zobunjiniyela bemishini. Le mfanelo yayivame ukusetshenziselwa izakhiwo zensimbi, noma kunjalo.
Ulwazi olungezansi luchaza izindinganiso eziyinhloko nezimfanelo zensimbi ngaphansi kwesistimu entsha yamazinga.

Amapayipi Angenamthungo namashubhu Okufaka Izicelo Zengcindezi

I-EN 10216 Euronorm ingena esikhundleni se-DIN 17175 endala kanye namazinga we-1629. Leli zinga lakhelwe amapayipi asetshenziswa ekufakweni kwengcindezi, njengepayipi. Kungakho izimfanelo zensimbi ezihlotshaniswayo ziqokwa ngohlamvu P oluthi 'Ingcindezi'. Inani elilandela le ncwadi libonisa ubuncane bamandla esivuno. Izimpawu zezincwadi ezilandelayo zinikeza ulwazi olwengeziwe.

I-EN 10216 iqukethe izingxenye ezimbalwa. Izingxenye ezibalulekile kithi zimi kanje:

• I-TS EN 10216 Ingxenye 1: Amapayipi angewona ama-alloy anezakhiwo ezishiwo ekamelweni lokushisa
• I-TS EN 10216 Ingxenye 2: Amapayipi angewona ama-alloy anezindawo ezishiwo emazingeni okushisa aphezulu
• I-TS EN 10216 Ingxenye 3: Amapayipi e-alloy enziwe ngensimbi ecolisekile yanoma ikuphi izinga lokushisa

Ezinye izibonelo:

1. I-EN 10216-1, Ikhwalithi P235TR2 (ngaphambilini eyayiyi-DIN 1629, St.37.0)
   P = Ingcindezi
   235 = ubuncane besivuno samandla ku-N/mm2
   I-TR2 = ikhwalithi enezakhiwo ezicacisiwe ezihlobene nokuqukethwe kwe-aluminium, amanani omthelela kanye nezidingo zokuhlola kanye nokuhlolwa. (Ngokungafani ne-TR1, okungashiwongo ngayo lokhu).
2. I-EN 10216-2, Ikhwalithi engu-P235 GH (ngaphambilini eyayiyi-DIN 17175, St.35.8 Cl. 1, ipayipi lebhayela)
   P = Ingcindezi
   235 = ubuncane besivuno samandla ku-N/mm2
   GH = izakhiwo ezihloliwe emazingeni okushisa aphezulu
3. I-EN 10216-3, Ikhwalithi P355 N (ilingana ngaphezulu noma ngaphansi ne-DIN 1629, St.52.0)
   P = Ingcindezi
   355 = ubuncane besivuno samandla ku-N/mm2
   N = ejwayelekile*

* Ukujwayela kuchazwa ngokuthi: okujwayelekile (okufudumele) okugoqiwe noma okujwayelekile (emazingeni okushisa amaminithi angu-930°C). Lokhu kusebenza kuzo zonke izimfanelo ezibekwe ngohlamvu 'N' Emazingeni e-Euro amasha.

Amapayipi: amazinga alandelayo athathelwa indawo yi-DIN EN
