Ul U425, Product iQ is UL Solutions' online location for certification information.

Ul U425, UL U425 is a fire rating system for wall and partition assemblies with metal stud, gypsum board, lath and/or plaster. It combines data from many legacy UL solutions, including the Online Certification Directory, Product Spec and several iQ databases into one streamlined experience. ASTM E119, Standard Test Methods for Fire Tests of Building Construction and Materials, is the test standard for determining the fire-resistance rating of partitions, floor-ceiling assemblies, roof-ceiling assemblies UL Design No. Mar 2, 2022 · See General Information for Fire-resistance Ratings - ANSI/UL 263 Certified for United States Design Criteria and Allowable Variances Fire-resistance ratings have long been used by UL/ULC,ASTM and building codes to measure the performance of various constructions for fire containment purposes. As applied to elements of buildings, the fire-resistance rating classifies the ability of an assembly to confine and isolate fire within a zone comprised of fire resistance-rated walls, ceiling and floor assemblies. Fire-resistance ratings have long been used by UL/ULC,ASTM and building codes to measure the performance of various constructions for fire containment purposes. The catalog lists fire ratings for USG panels and UL fire ratings, as well as flame spread, smoke developed and noncombustible materials. The Guide Information, Assemblies, Constructions, Designs, Systems, and/or Certifications (files) must be presented in their entirety and in a non-misleading manner, without any manipulation of the data (or drawings).
