FOREWORD
This addendum clarifies the standard in three areas. Equation 14 is modified to clarify for which airstream the specific heat Cp is evaluated. Text near Equations 22 and 23 is rearranged for clarity. Two sets of uncertainty limits had been provided for Equations 24, 25, and 26; in this addendum each equation is provided with a single, unambiguous uncertainty limit.
Note: In this addendum, changes to the current
standard are indicated in the text by underlining (for
additions) and strikethrough (for deletions)
unless the instructions specifically mention some other means of
indicating the changes.
