It would be nice if you also informed us where you found this...

You may have guessed yourself that IBPT stands for Initial Boiling Point, so this fraction starts to boil at 442.4 °F, while 5% of the liquid has boiled off at 592.8 °F, etc.
I have no idea what the BP means in IBPTBP.

Dear,
I think you are asking about the crude TBP (True Boiling Points) curves which are nothing but the graph of Temperature vs The % Distilled (Crude) in which the lowes temp is termed as IBP-intial boiling point temperature and the max temp is termed as FBP-final boiling point temperature.And the total range is the TBP.
I hope this could solve your doubt.

That s a crude distillation point... I think I understand what it means. I came accross it on an online article... Thank you very much for the explanation and sorry for the incomplete posting.
