Engineering judgments are an alternative means to assembly-test for achieving third-party ASTM E2307 certification. Typically, an engineering judgment will be used when minor modifications or material substitutes to existing ASTM E2307 listings are requested. Engineering judgments are never 100% guaranteed, however, and rely on several factors when being evaluated. They can be completed by UL, Intertek, most firestop manufacturers or any third-party, licensed, professional engineering consultant.

Engineering judgments should be closely reviewed to ensure that the listed manufacturer has tested assemblies, and the requirements of those systems must be incorporated into the judgment. Note that ROCKWOOL is not authorized to complete engineering judgments; however, we can assist by working closely with our firestop partners. Our team will provide a recommendation on how best to service an engineering judgment request.
