In diverse architectural and access control scenarios, selecting the appropriate mortise lock is critical to ensuring security and functional efficiency. Known for their mechanical strength, durability, and versatile configurations, mortise locks have become the preferred solution for applications r
The European Standard EN 1303:2015 evaluates and tests lock cylinders for durability, fire resistance, attack resistance, and more. It classifies products via an 8-digit coding system, where each digit represents specific performance characteristics against standardized requirements. This coding sys
Fire doors are critical components of a building’s passive fire protection system. Designed to contain flames and smoke within specific areas, they create physical barriers that provide evacuation time for occupants and minimize fire damage. Fire doors must comp
In our previous article, we explored the classification codes for EN12209 mechanical locks and strike plates. This time, we will focus on the standardized performance grading of a complementary component—lever handles and knob furniture—according to the EN 1906 standard. Utilizing an 8 - digit codin
EN 12209 is a European standard that establishes performance requirements and test methods for mechanically operated locks and locking plates in the field of architectural hardware. It sets clear testing standards and grading systems for key indicators such as durability, security, fire resistance,
