|Publication Date:||30 April 2021|
Addendum b to Standard 55-2020 changes the upper metabolic rate limit for the standard from 2 to 4. This change aligns the standard with ISO Standard 773 and is motivated by consistent recent research that supports the applicability of Standard 55 at this metabolic level.
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.
