Section 188.8.131.52 states "all sprinklers within the area represented by that sample shall be replaced." What is considered the "area?"
Look at the prior section:
Or test more heads.
Some how someone came up with what area, building, floor, whatever to sample, So that is the sample area.
Say someone picked an open warehouse as the sample area, then it would be the entire warehouse.
184.108.40.206* A representative sample of sprinklers for testing per 220.127.116.11.1 shall consist of a minimum of not less than four sprinklers or 1 percent of the number of sprinklers per individual sprinkler sample, whichever is greater.
A.18.104.22.168 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.
This is what I found in the handbook:
"The sample should be somewhat random and should be representative of the sprinklers installed in the system. For example, sprinklers should be selected from different floors or areas of the building and not selected simply because they are more accessible than other sprinklers. In addition, the selection should take into consideration the age andtypes of sprinklers as well as environmental conditions to which they are subjected.
The inspector and/or the owner can determine which groups of sprinklers the sprinkler sample represents. Keep in mind that if a single sprinkler from the sample fails the plunge test, all the sprinklers that the sample represents must be replaced. The sample can represent an entire system or one floor of a multi-story building.
Note that only sprinklers that have been exposed to service conditions must be tested. The sprinklers in the spare sprinkler cabinet, for example, have not been exposed to service conditions and may not reveal any deficiencies."
Hope this explains.
