FOREWORD
This addendum addresses concerns regarding partial, shortcut, or initial testing only that can misstate the MERV performance classification and discredit the validity of the minimum reporting requirements of the standard.
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.
