DIN EN 1090-1:2012-02

Placing load-bearing steel and aluminium components on the European market in compliance with standards

DIN EN 1090-1 specifies the requirements for the assessment of conformity of load-bearing steel and aluminium components. It describes the conditions for assessing and verifying performance characteristics and for the CE marking of load-bearing components. The standard provides the basis for placing load-bearing steel and aluminium construction products on the European market.

What is DIN EN 1090-1 about?

The standard defines procedures for the assessment and verification of the performance characteristics of load-bearing components and kits. It focuses on requirements relating to load-bearing capacity, fatigue strength, fire resistance, durability, dimensional accuracy and weldability, as well as the necessary verification procedures. It also describes the requirements for factory production control (FPC), initial type testing and the issuance of declarations of conformity.

It applies to load-bearing steel and aluminium components placed on the market as construction products, including components for composite steel and concrete structures.

Topics covered

• Assessment of conformity for load-bearing steel and aluminium components
• CE marking of construction products
• Factory production control (FPC)
• Initial type testing (ITT) and initial type calculation (ITC)
• Load-bearing capacity, fatigue strength and fire resistance
• Weldability and fracture toughness
• Durability and corrosion protection
• Execution classes EXC1 to EXC4
• Manufacturer’s and purchaser’s component specifications (MPCS/PPCS)

Practical relevance

DIN EN 1090-1 is the key basis for manufacturers of load-bearing steel and aluminium components seeking to place their products on the European market with CE marking. The standard helps manufacturers demonstrate performance characteristics transparently and establish the processes required for production and quality assurance.

The requirements for factory production control (FPC) and execution classes EXC1 to EXC4 are particularly relevant, as they form the basis for certification, surveillance and conformity assessment. In practice, the standard is regularly applied together with DIN EN 1090-2 and DIN EN 1090-3.

Changes compared with DIN EN 1090-1:2010-07

The following changes have been made compared with the previous edition:

• Addition of provisions relating to deformations at the serviceability limit state
• Editorial revision of Annex ZA.1
• Replacement of the abbreviation KLF with NPD (No Performance Determined)

Target audience

• Steel construction companies
• Aluminium construction companies
• Manufacturers of load-bearing components
• Design engineers and structural engineers
• Quality managers
• Certification bodies
• Independent checking engineers and technical experts
• Specialists in CE marking and construction products law

Conclusion

DIN EN 1090-1 provides the basis for the assessment of conformity of load-bearing steel and aluminium components. Through its requirements for performance assessment, factory production control and documentation, it supports manufacturers in demonstrating construction product characteristics in compliance with standards and gaining access to the European market.
