ENGINEERING JUDGEMENTS (EJ’S) also called Engineering Evaluations, EEV’s, come into play when materials, products or systems cannot be installed in strict accordance with the certification documents (i.e. identical to the way it was tested). This can sometimes be resolved with an EJ prepared by the Certification Body or a fire consultant, provided supporting data is available. EJs are formally justified documents based on actual test data and published science and engineering. If data cannot be provided or found we may recommend some additional indicative or full-scale testing as required to support the EJ.
