ICC-ES does not offer an opinion on changes to a recognized product or system until evidence has been submitted, evaluated, and recognized in the evaluation report. Fire-resistive assemblies are recognized by ICC-ES only as described in the applicable evaluation report. Assemblies made up of different components than those described in the evaluation report are not recognized.
Please be advised that any changes to components of a classified roofing system, as described in an ICC-ES evaluation report, negates ICC-ES recognition of the classification. The changes may or may not affect the actual classification, but until they are subjected to appropriate testing or are evaluated by a testing agency and declared to be acceptable under the designated classification, ICC-ES is unable to make a determination as to proper classification.
