Among the mentioned equipment, the HST NDS-2000 Torsion Test Machine meets the requirements of the EN 14399-2 test standard. EN 14399-2:2015, a European standard approved by CEN, specifies technical requirements and test procedures for high-strength structural bolting assemblies to ensure their suitability for preloading in metallic structures, focusing on the overall performance of bolt-nut-washer combinations rather than individual parts. The HST NDS-2000 is specifically designed to conduct torsion tests on fasteners like high-strength bolts, aligning with the standard’s core demands.
Abstract:
The HST NDS-2000 Torsion Test Machine is a high-precision 1-class test equipment with a maximum torque of 2000 N·m, capable of real-time displaying torque, torsion angle, speed and peak values during tests. It complies with EN 14399-2, as well as other standards, and is widely used in testing high-strength structural bolting assemblies, verifying their preload suitability by simulating actual working conditions. This machine features automatic stop, double limit protection and overload protection, ensuring accurate and safe test results for aviation, construction and industrial fields.
Takeaways:
- The HST NDS-2000 is fully compliant with EN 14399-2, making it reliable for testing preload suitability of high-strength bolt assemblies.
- Its high precision (torque accuracy ≤±1%) and comprehensive protection functions guarantee test reliability and safety.
- It supports two-way rotation and stepless speed adjustment, adapting to diverse test needs of EN 14399-2.
4. EN 14399-2 focuses on overall assembly performance, and the HST NDS-2000 effectively simulates practical stress to validate bolt assembly safety and ductility.
