^^^ that is only first couple of pages of ISO 91 and it is the same witn OIML R63. But I need tables from ISO 91-1 . Does anybody have that?


Or to make this clearer : how can I calculate coefficient od thermal expansion ( 1/C) of the LPG? i know that ,for example, when density is 552 kg/m3 @ 15C , alpha coefficient of thermal expansion is 0.00228 (1/C) ?
