Relationship between Hazard Classifications and Sprinkler Activation Temperature

[sl3656]

Is there any relationship / requirement indicated in NFPA 13 between the hazard classifications and the required sprinkler activation temperature?

There is a clear relationship between the hazard classification (e.g. LH, OH1, OH2, etc.) and sprinkler application density, but does a similar one exist for above?

Table 6.2.5.1 (NFPA 13 - 2016) dictates the sprinkler temperature ratings, classifications and color codings, but as I understand it, it appears the designer is free to use whatever activation temperature he / she desires independent of the hazard classification, except under 22.35.1.3.5, which is only applicable to underground conveyors.

Appreciate any insight into this. Thanks.

Read more closely. You are permitted to use ordinary/intermediate temp sprinklers throughout all areas, unless a higher temperature is required due to proximity to heat source. Also, there are some provisions in EH and Storage to reduce the design area by 25% for the use of high temp sprinklers.

So, the temperature rating of the sprinkler is per the designer's discretion to a point. You can't go and just throw 360°F sprinklers throughout simply because you want to.
