EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 14399-1 testing. This European Standard specifies general requirements for bolt/nut/washer(s) assemblies for preload, high strength structural bolts. The intended use of bolt assemblies according to this European Standard is for structural metallic work.
The performance of high-strength structural bolt assemblies is dependent on the type of bolt assemblies and the characteristics of their particular components (bolts, nuts, washers, and direct tension gauges, if any).
Specifically, EN 14399-1 focuses on general requirements for high-strength structural bolt assemblies for preloading. Preloading refers to the deliberate application of a pulling force to a bolted joint to ensure that the joint remains firmly connected even under external loads and vibrations. This helps prevent bolts from loosening and maintain the structural integrity of the assembly.
A feature class succinctly expresses a set of mechanical properties of components. It concerns the compatibility of components with each other in order to achieve the declared performances of the bolt assemblies.
The product class covers dimensional and shape tolerances for bolts, nuts and washers. The product class covers three critical features for direct voltage indicators. It concerns the compatibility of components with one another to ensure the declared performance of bolt assemblies.
The standard can provide guidance on appropriate procedures for obtaining and verifying the desired preload force in bolt assemblies. This may include torque tightening, stretching, or a combination of methods.
