How can I use ISO 2631 figure for ride comfort analysis?

How should I exactly process the vertical acceleration signal (with respect to time) to be able to adapt it on the ISO2631 curves (as attached). As far as I know, First I should find rms of the acceleration, then FFT and after that 1/3 octave filter. is there any matlab code for this process? or any pdf that help with using iso2631 figure?
another question is, what if the peak point of the fft curve of the acceleration signal does not meet one of the ISO2631 curves (as shown in the attached picture)? Is there any interpolation method to find the exact amount of time that the human body can endure the vibration in this case?

Hi Iman,
My latest publication might answers your question.

Sename, "Integrated multi-criteria velocity and semi-active suspension control based on look-ahead road information," 2020 28th Mediterranean Conference on Control and Automation (MED), Saint-Raphaël, France, 2020, pp. 25-30, doi: 10.1109/MED48518.2020.9182953.
Good luck.
