However, the general specifications and plumbing notes require firestopping assemblies to be UL-listed and have a rating that matches the wall being penetrated, which may be 1-hour or 2-hour. Applying a blanket 3-hour requirement via a detail, without reference to a specific UL assembly or the actual wall rating, is contradictory and may lead to non-compliant installations. The detail should require a UL assembly appropriate for the specific wall rating.", "evidence": [{"discipline": "General", "sheet": "G31.04", "source_text": "FIRESTOPPING: TESTED IN ACCORDANCE WITH ASTM E119 OR UL 263 TO MEET THE HOURLY F-RATINGS OF THE CONSTRUCTION BEING PENETRATED.", "asserted_value": "Firestopping rating to match the penetrated element's rating"}, {"discipline": "Plumbing", "sheet": "P01.01", "source_text": "7.
