API 5L, nrog nws lub npe tag nrhoAmerican roj teeb spressification 5L, yog tus qauv kev tshwj xeeb rau kab xaim yas ntawm cov roj av thiab roj av lag luam, tsim los ntawm American roj av (API). Txij li thaum nws thawj cov ntawv tshaj tawm hauv xyoo 1926, tus qauv no tau dhau los ntau yam kev hloov kho thiab txhim kho ib tus qauv lees paub. API 5L Tsis yog cov kev yuav tsum tau ua xws li cov khoom siv hlau, thiab x 5
