Extension of the scope of fire resistance tests. Non-load-bearing walls. Part 4: Structures with enamel glass walls

This technical document establishes specific requirements for evaluating the fire resistance of non-load-bearing walls, with a particular focus on glazed wall assemblies. It defines test procedures and classification criteria to determine the performance of architectural glazing systems under standardized fire conditions. The scope explicitly covers walls constructed with enamelled glass panels designed for building facades and interior partitions where structural support is not required. Methodology includes rigorous assessment of integrity, insulation, and radiation properties during exposure to elevated temperatures. Key aspects involve preparation of test specimens, mounting configurations, and criteria for determining failure limits based on heat transfer and structural stability. The document provides guidance for laboratories and manufacturers to ensure consistent evaluation across different building applications. Compliance with these guidelines facilitates comparative analysis of fire safety performance for various glass wall systems in non-load-bearing contexts. Implementation aids in maintaining building safety standards while accommodating modern architectural designs that utilize extensive glazed surfaces. The approach aligns with broader international frameworks for fire testing of construction products.
