Door leaves - Determination of the resistance to hard body impact

This document specifies the test methods for evaluating the ability of door bolts to withstand impacts from solid objects. It defines the procedures for subjecting door bolts to controlled impact loads to determine their resistance and durability under such conditions. The standard outlines the equipment required for testing, including impact hammers and support fixtures, as well as the specific impact energy levels and frequencies to be applied. Detailed instructions are provided for preparing test specimens and conducting the impact tests under standardized laboratory conditions. The results obtained from these tests are used to classify the performance of door bolts regarding their capability to resist mechanical impacts from solid materials. This approach ensures consistency and reliability when assessing the impact resistance of door locking components across different manufacturing facilities. The methodology aims to provide manufacturers and users with a clear understanding of product performance under impact scenarios without making subjective judgments on the overall utility or necessity of the specification.
