Engineering Judgements

Engineering Judgements

Engineering Judgements Engineering judgements (EJ's) are used when a tested, UL classified system is not available. The EJ is based on existing technology and available tested systems. EJ's must be conducted by the manufacturer’s technical or engineering group.  The installing contractor cannot write their own EJ! A third party review of the EJ is desirable but not required. EJ's can only be applied to the specific application for which they were written.
