EN ISO 14140-2:2021 is a professional technical standard that establishes specific test methods for determining mechanical durability, sound insulation, and mechanical testing of building hardware. It was published by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN).
Mechanical Durability Testing
In accordance with EN ISO 14140-2:2021, mechanical durability testing assesses the ability of building hardware to withstand repeated use over an extended period of time. This testing aims to evaluate the robustness and reliability of components such as door handles, locks, hinges, and window mechanisms.
The test involves subjecting the hardware to repeated cycles of opening and closing, applying specified forces and movement patterns. By monitoring the performance of the hardware during the test, manufacturers and users can determine its expected lifespan and durability in real-life scenarios.
Sound Insulation Testing
EN ISO 14140-2:2021 also provides guidelines for sound insulation testing of building hardware. Sound insulation is crucial for creating acoustically comfortable spaces, particularly in buildings such as hospitals, offices, and residential properties. This test evaluates the ability of hardware, such as doors and windows, to reduce noise transmission between rooms or from outside to inside.
During sound insulation testing, the hardware is mounted in a test structure that replicates real-world conditions. Sound sources are placed on one side of the structure, while sound level meters measure the sound transmission on the other side. The test determines the sound reduction index or sound transmission class of the hardware, helping architects, engineers, and designers select appropriate products for their projects.
Mechanical Testing
EN ISO 14140-2:2021 includes mechanical testing methods for evaluating the strength and performance of building hardware. This encompasses various mechanical aspects, such as load-bearing capacity, resistance to corrosion, endurance under extreme temperatures, and resistance to impacts or environmental conditions.
By subjecting the hardware to rigorous mechanical testing, manufacturers can ensure that their products meet quality and safety standards. These tests help determine if the hardware will withstand anticipated pressures, forces, or other mechanical stresses that occur during installation, operation, or maintenance.
Overall, EN ISO 14140-2:2021 is an essential standard that provides comprehensive testing procedures for mechanical durability, sound insulation, and mechanical properties of building hardware. Adhering to this standard ensures that products meet industry requirements and helps create safer and more comfortable built environments for everyone.
