What is an engineering judgement?
Engineering judgements are recommended solutions for specific jobsite conditions
For firestop, an engineering judgment, or EJ, is a drawing or group of drawings usually generated by a firestop manufacturer for a customer’s jobsite-specific application. They are recommended solutions when jobsite conditions deviate from a tested firestop design or system.
Hilti firestop solutions are tested against the most stringent test standards such as ASTM/UL and EN1366-3 and -4. But it’s not possible to test every firestop application, because construction projects are all very different. That’s why we offer EJs.
