What is the EN 14399-1 Standard?

The EN 14399-1 standard is a European standard that defines the general requirements for preloaded high-strength structural bolting assemblies. It specifies the performance characteristics, manufacturing conditions, and conformity assessment criteria for fasteners.

The different parts within the EN 14399 series cover technical requirements for bolts, nuts, washers, and overall system performance. Thanks to these standards, reliability and traceability are ensured in structural connections.

How is EN 14399-1 Conformity Assessment Performed?

Conformity assessment activities under EN 14399-1 are carried out in accordance with the requirements of the relevant standard.

• Receiving the application and defining the scope,
• Reviewing technical documentation,
• Evaluating production processes,
• Examining quality control records,
• Assessing required test and inspection results,
• Issuing certification if conformity requirements are fulfilled.

After certification, surveillance activities are conducted at defined intervals to ensure the continuity of the system.
