Recent changes to E2190 now require testing of a "Baseline" set of specimens without internal components (i.e. decorative grids, blinds, art glass, and the like). This Baseline set has to pass testing for both accelerated weathering (E2188) and volatile fog (E2189). Internal components are tested for fog only as a separate, standalone test. This was done to allow manufacturers to test more types of internal components individually, and not affect certification of their baseline set. However, there were concerns expressed that some internal components and/or their attachments may affect the weather durability of IG unit. Previous wording was attempted, but did not make it through a ballot. This work item is to resume this task, and draft appropriate language for E2190 addressing this aspect of internal components.
