What is the EN 1090-1 Standard?

The EN 1090-1 standard is a harmonized European Standard that defines the conformity assessment requirements for steel and aluminium structural components. The standard aims to ensure controlled manufacturing processes, product traceability, and the safety and reliability of structural applications.

The EN 1090 series generally consists of the following parts:

• EN 1090-1: Conformity assessment and CE marking requirements.

• EN 1090-2: Technical requirements for steel structures.

• EN 1090-3: Technical requirements for aluminium structures.

How is EN 1090-1 Conformity Assessment Carried Out?

During the EN 1090-1 certification process, the manufacturer’s quality management system, production activities, and technical records are evaluated in accordance with the requirements of the relevant standard.

The process generally consists of the following stages:

• Application submission,

• Review of technical documentation,

• Assessment of the Factory Production Control (FPC) system,

• Audit of production processes,

• Evaluation of personnel qualifications and welding activities,

• Certification upon successful fulfillment of conformity requirements.

Following certification, periodic surveillance activities are conducted to monitor the continued effectiveness and compliance of the system.

Why is EN 1090-1 Applied?

The EN 1090-1 standard is applied for the following purposes:

• Supporting structural safety,

• Ensuring that production processes are carried out according to defined criteria,

• Verifying product performance,

• Enabling access to the European Union market,

• Meeting CE marking requirements,

• Increasing acceptance in international projects

It is applied for these main objectives.

What are the Application Areas of EN 1090-1?

The EN 1090-1 standard covers steel and aluminium structural components used across many industries.

The main application areas are as follows:

• Steel structural building systems,

• Industrial facilities,

• Warehouses and hangars,

• Bridge and viaduct projects,

• Power plants,

• Platforms and walkways,

• Aluminium facade systems,

• Load-bearing metal structural components,

• Prefabricated building elements,

• Industrial machinery and support structures.

EN 1090-1 Equipment and Techniques

During conformity assessment activities, production processes and quality records are reviewed in accordance with the relevant standards. When necessary, the following elements may be included in the evaluation scope:

• Factory Production Control (FPC) records,

• Welder qualification certificates,

• Welding procedure specifications (WPS/PQR),

• Material certificates,

• Traceability records,

• Measurement and control equipment,

• Dimensional inspections,

• Non-destructive testing (NDT) results,

• Calibration records.

Advantages of EN 1090-1

EN 1090-1 provides several advantages to manufacturers.

• Supports the CE marking process.

• Increases competitiveness in international markets.

• Enhances customer confidence.

• Improves product traceability.

• Verifies that production processes are carried out in compliance with the standard.

• Increases reliability through independent third-party assessment.

• Improves acceptance in European Union projects.

Disadvantages of EN 1090-1

To comply with the requirements of the standard, manufacturers must maintain certain records and continuously manage their processes.

Therefore:

• Additional quality records may be required,

• Regular inspection processes are necessary,

• Continuous monitoring activities are required,

• Technical requirements must be consistently maintained.

However, the international acceptance and reliability provided by the standard offer significant advantages for many industries.
