Richard,
Thank you so much. The method of pulling out the specs and running the polynomial equations will a bit hazy and also have to refer some or more documents.
However, I wanted to know if I can get the value of "fh" by referring to the equations 12.1.3-3,12.1.3-2 and 5.3.2-1, as getting the value of "f" for equation 12.1.3-3 is vague at such and elevated temperature.
