The intent is to focus the sample so as to cover ALL the different potential environments that could impact the sprinkler operation. You obviously don’t want t pull a sample from just an air conditioned office space and not test any sprinklers from an exterior location like a loading dock. This concept of environment is identified in the Annex. I could have sworn we did a better job on this issue but it must have been a figment of my imagination. I do know the technical committee discussed this issue in great depth multiple cycles ago.
A.5.3.1.2 Within an environment, similar sidewall, upright, and pendent sprinklers produced by the same manufacturer could be considered part of the same sample, but additional sprinklers would be included within the sample if produced by a different manufacturer.
