FOREWORD
The purposes of Addendum a is to (a) clearly define the steady-state criteria, (b) add requirements to the test plan to match the inputs needed to determine when steady-state operating conditions have been achieved, and (c) correct the expansion factor equation.
Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and (for deletions) unless the instructions specifically mention some other means of indicating the changes.
