Decision of the National Institute of Standardization No. 382 of 09.10.2014

This technical specification establishes a framework for the assessment of concrete structures subject to fire exposure. It provides detailed methodologies and criteria for evaluating the fire resistance of existing buildings and new constructions. The document outlines procedures for testing and analyzing the performance of concrete elements under high-temperature conditions, ensuring safety and structural integrity during fire incidents. It addresses various aspects including load-bearing capacity, integrity, and thermal insulation requirements for concrete components. The guidance aids engineers and inspectors in determining the suitability of concrete structures for use in fire-prone environments. It also covers the classification of fire resistance based on specific time intervals and load conditions. By following these guidelines, stakeholders can better understand the behavior of concrete materials when exposed to fire, leading to more informed decisions regarding structural safety and rehabilitation. The approach ensures consistency in evaluating fire performance across different projects and regions.
