nfpa 25 requires building owners to have a sample of the installed sprinklers tested by a recognized testing lab. nfpa 25 section 22.214.171.124 states a representative sample of sprinklers for testing 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. for example, let’s look at a 20 story building with 200 of the same type of sprinkler on each floor. in the 2nd example, you would be required to take 1% of the whole building or just 40 sprinklers in total. however, consider what nfpa 25 says about sprinklers failing to meet performance requirements: “where one sprinkler within a representative sample fails to meet the test requirements, all sprinklers within the area represented by that sample shall be replaced.” in the first example, if they had one sprinkler fail on the 1st floor, they would only need to replace that floor’s sprinklers since each floor was represented by a different sampling.
nfpa 25 section 5.3.1 testing sprinklers, makes the following recommendations for when to either test or replace sprinklers installed in systems. solder type sprinklers with a temperature classification of extra high (325° f, 163° c) or greater that are exposed to semi continuous to continuous maximum allowable ambient temperature conditions dyne tests the response time of the sprinklers to ensure the sprinklers will release in a specified amount of time when exposed to a defined temperature and air flow. note that a sprinkler coated with a material for corrosion resistance (wax for example) is allowed extra time as defined in ul 199. the response time of coated standard response sprinkler is 180 seconds or the maximum response time (whichever is greater). if the response time does not meet the rti requirement, the sprinkler response time will be marked as “fail”. if a sprinkler fails to meet the response requirements as defined above, all sprinklers within the area represented by the failure shall be replaced per nfpa 25 2020 ed. the image of the sprinkler waterway post-testing can be used to help identify any obstructions that may still impede functionality.
