Fireproof safes. Requirements and test methods for fire resistance

This document specifies the fire resistance requirements and test methods for fireproof safes. It outlines the conditions under which these safes must perform in order to ensure the protection of contents during exposure to fire. The scope includes the determination of fire resistance duration, the integrity of the safe's structure, and the ability to maintain internal temperature levels below specified thresholds. The document details the procedures for conducting fire resistance tests, including the setup of test environments, the application of heat sources, and the measurement of key performance indicators. It also covers the classification of safes based on their fire resistance capabilities and the marking requirements to indicate compliance with the specified standards. The information provided is intended to support the development, testing, and certification of fireproof safes to ensure they meet the necessary safety and performance criteria.
