Building hardware - Emergency exit devices operated by a lever handle or push pad, for use on escape routes - Requirements and test methods

This technical specification outlines the essential requirements and test methods for manual lever-type or push-type emergency exit devices designed for use along escape routes within buildings. The document focuses on ensuring that these mechanisms function reliably during emergency situations to facilitate the rapid and safe evacuation of occupants. It details the mechanical performance criteria, including the force required to operate the device, the durability of components under repeated use, and the resistance to environmental factors such as temperature fluctuations and humidity. The text specifies how the devices must respond when activated, ensuring they allow immediate egress without the need for keys or special knowledge. Furthermore, it establishes the procedures for validating that the product meets the necessary safety thresholds through standardized testing protocols. By defining these technical parameters, the document aims to harmonize the design and implementation of such safety systems across relevant markets, ensuring consistency in functionality and reliability for all installations in both public and private structures.
