Calculate equivalent P.bv and dynamic gas force from press test to determine preload on the icpsring. However, the act gas force will be approx 1-2 lbs higher than calculated due to thermal expansion of the hot ctg oil.  For a more accurate icspr preload, set preload so the calculated icspr force is about 1-2 lbs less than actual.         vs_fics   The text boxes populate with the appropriate numbers from vs_fics . . . using strpos() . . . adjust as needed           kg/mm   icspr rate zero indicates the icspr did not have prel-->     mm   icspr prel (+nu . . not zero)           mm   ctg rod dia           mm   icpist dia             mm   icrod dia           mm   dyno test stroke             mm   dyno prel              mm   9 oclock gas test position       Results             907.92     mm^2   icpist area       78.54     mm^2   icrod area          829.38     mm^2   icpist area - icrod area       126.2     mm   ctg rod stroke       113.1    mm2   ctg rod area            ctg rod area inches = ( 0.1753 in2)   ct       14272.88     mm3   ctg rod vol      17.21     mm    icpist stroke         17.21     mm   icspr stroke (icpist_stroke + prel)         0     kgf   icspr force kg   Fork pressure tests do not include the full fork, but only the (sealed) twin chamber cartridge assembly.  Gas forces are removed from the test allowing analysis of the hydraulic damping force only.  The fork ctg gas force is reliant on the stiffness of the icspring and icspr preload.
