The results of this testing is intended to assist interested parties including the local Authorities Having Jurisdiction (AHJ) in accessing the operating characteristics of the sprinklers. Please consult the local Authorities Having Jurisdiction (AHJ) regarding the interpretation of the test results described in the attached Test Summary Table(s).” Apparently, the testing laboratory will not indicate “failure” of the sprinkler that was tested. The guidance in 5.3.1.3 says that where one sprinkler within a representative sample fails to meet the test requirement, all sprinklers within the area represented by that sample shall be replaced. A literal interpretation of 5.3.1.3 indicates to replace the sprinklers. The report did not indicate a failure to discharge. The Water-Based Fire Protection Systems Handbook commentary under 5.3.1.1 states, “If the sprinkler fails to operate in the specified amount of time, the sprinkler fails the test and all sprinklers represented by the test sprinkler must be replaced.” The annex material in A.5.3.1.1 creates confusion by referencing sprinklers that have been in service
