What is the EN 15048-1 Standard?

The EN 15048-1 standard is a harmonized European standard that defines the general requirements and conformity assessment rules for non-preloaded structural bolting assemblies. It specifies the performance characteristics, marking requirements, and basic criteria for production processes of fastening components.

Through this standard, the aim is to ensure reliability in structural connections, product traceability, and continuous quality assurance.

How is EN 15048-1 Conformity Assessment Performed?

Conformity assessment activities under EN 15048-1 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 test and inspection results,
• Issuing certification if the requirements are met.

After certification, surveillance activities are carried out at regular intervals to ensure the continuity of the system.
