Izikhundla zeDIN ezindala nezintsha

Ukutyhubela iminyaka, imigangatho emininzi ye-DIN yadityaniswa kwimigangatho ye-ISO, kwaye ngaloo ndlela ikwayinxalenye yemigangatho ye-EN. Kwinkundla yohlaziyo lwemigangatho yaseYurophu imigangatho yeDIN yarhoxa yaze yathatyathelwa indawo yiDIN ISO EN kunye neDIN EN.
Imigangatho esetyenziswe kwixesha elidlulileyo efana ne-DIN 17121, i-DIN 1629, i-DIN 2448 kunye ne-DIN 17175 ukususela ngoko ithathelwe indawo yi-Euronorms. Ii-Euronorms zahlula ngokucacileyo indawo yokusetyenziswa kombhobho. Ngenxa yoko imigangatho eyahlukeneyo ngoku ikhona kwimibhobho esetyenziswa njengemathiriyeli yokwakha, imibhobho okanye usetyenziso lobunjineli boomatshini.
Lo mahluko wawungacace kangako kwixesha elidlulileyo. Ngokomzekelo, umgangatho omdala we-St.52.0 wawuthathwe kumgangatho we-DIN 1629 owawujoliswe kwiinkqubo zemibhobho kunye nezicelo zobunjineli bomatshini. Lo mgangatho wawusoloko usetyenziselwa izakhiwo zentsimbi, nangona kunjalo.
Ulwazi olungezantsi luchaza imigangatho ephambili kunye neempawu zentsimbi phantsi kwenkqubo entsha yemigangatho.

Imibhobho engenamthungo kunye neMibhobho yezicelo zoxinzelelo

I-EN 10216 Euronorm ithatha indawo ye-DIN 17175 endala kunye nemigangatho ye-1629. Lo mgangatho wenzelwe imibhobho esetyenziswa kwizicelo zoxinzelelo, njengombhobho. Kungenxa yoko le nto iimpawu zentsimbi ezinxulumene nazo zichongwa ngunobumba P 'woxinzelelo'. Ixabiso elilandela le leta lichaza amandla emveliso amancinci. Ukutyunjwa kweeleta ezilandelayo kunika ulwazi olongezelelweyo.

I-EN 10216 ineenxalenye ezininzi. Amalungu afanelekileyo kuthi alandelayo:

• I-EN 10216 Icandelo le-1: imibhobho engeyiyo i-alloy eneempawu ezichaziweyo kwiqondo lobushushu begumbi
• I-EN 10216 Icandelo le-2: imibhobho engeyiyo i-alloy eneempawu ezichaziweyo kumaqondo obushushu aphezulu
• I-EN 10216 Icandelo le-3: Imibhobho yealloy eyenziwe ngentsimbi ecolekileyo kulo naliphi na iqondo lobushushu.

Eminye imizekelo:

1. I-EN 10216-1, Umgangatho we-P235TR2 (yayesakuba yi-DIN 1629, St.37.0)
   P = Uxinzelelo
   235 = ubuncinci amandla esivuno kwi-N/mm2
   I-TR2 = umgangatho kunye neepropati ezichaziweyo ezihambelana nomxholo we-aluminium, ixabiso leempembelelo kunye nokuhlolwa kunye neemfuno zovavanyo. (Ngokuchaseneyo ne-TR1, apho oku kungachazwanga).
2. I-EN 10216-2, Umgangatho we-P235 GH (eyayifudula i-DIN 17175, i-St.35.8 Cl. 1, umbhobho webhoyila)
   P = Uxinzelelo
   235 = ubuncinci amandla esivuno kwi-N/mm2
   GH = iipropathi ezivavanyiweyo kumaqondo obushushu aphezulu
3. I-EN 10216-3, Umgangatho we-P355 N (ngaphezulu okanye ngaphantsi ngokulingana ne-DIN 1629, St.52.0)
   P = Uxinzelelo
   355 = ubuncinci bamandla esivuno kwi-N/mm2
   N = iqhelekile*

* I-normalized ichazwa njenge: i-normalized (eshushu) iqengqeleke okanye i-annealing esemgangathweni (kwiqondo lokushisa elingaphantsi kwama-930 ° C). Oku kusebenza kuzo zonke iimfanelo ezimiselwe ngunobumba 'N' kwiMigangatho emitsha ye-Euro.

Imibhobho: le migangatho ilandelayo ithathelwa indawo yi-DIN EN

Imibhobho yezicelo zoxinzelelo

* Imigangatho ye-ASTM iya kuhlala isebenza kwaye ayisayi kutshintshwa
