EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 14399-9 testing. The standard defines the scope and purpose of Section 9, which specifies requirements and specifications for direct strain gauges used with high-strength structural bolt and nut assemblies in the System HR or HV categories.
Direct tension gauges are devices used in bolted connections to provide a visual indication of the tension applied to the bolt. They help ensure that the specified preload is achieved, which is crucial for maintaining the structural integrity of the assembly.
EN 14399-9 can outline how direct tension gauges should be identified, marked and defined to indicate their specific characteristics, grades and conformance to the standard.
The standard may specify the types of materials that can be used in the manufacture of direct tension gauges. These materials must have the necessary mechanical properties and durability.
EN 14399-9 will likely define the required mechanical properties of direct strain gauges, including specifications for factors such as hardness and strength.
The standard can provide guidance on appropriate procedures for installing direct tension gauges with high-strength bolt and nut assemblies. This may include recommendations for correct placement and use.
The standard may outline the quality control measures that manufacturers must implement to ensure that their direct voltage indicators meet the required standards and specifications.
