IPIPI YEBANGA B YE-API 5L Umfanekiso Obonakalayo

Inkcazo emfutshane:

Igama: Ipayipi ye-API 5L yeBanga B

I-API 5L yeyona migangatho idumileyo yepayipi yomgca eyenziwe yi-Amercian Petroleum Institute. Kwangaxeshanye, i-ISO3183 kunye ne-GB/T 9711 zimigangatho yamazwe ngamazwe kunye nemigangatho yaseTshayina yepayipi yomgca ngokwahlukeneyo. Singenza iipayipi zomgca ngokwemigangatho emithathu ekhankanyiweyo.
