Scope of Eurocode Part

1.1.1 Application

(1) This Part 2 gives the basis for the design of aluminium alloy structures with respect to the limit state of fatigue induced fracture. Design for other limit states is covered in Part 1.

(2) This Part 2 gives rules for design by the following methods:

- Safe life

- Damage tolerance

- Design by testing

(3) This Part 2 contains the manufacturing quality requirements necessary to ensure that the design assumptions are met in practice.

1.1.2 Structural forms

- Beams and braced and unbraced framed structures

- Latticed structures

- Stiffened plate structures of flat or shell construction

- Solid bodies

(2) This Part 2 does not cover pressurised containment vessels, or pipework.

1.1.3 Basic products

- Rolled sections

- Extrusions

- Drawn Tubes

- Formed Profiles

- Forgings

- Castings

1.1.4 Member forms

(2) This Part 2 covers open and hollow sections, including members built up from combinations of these products.

1.1.5 Materials

(1) This Part 2 covers the wrought alloys listed with a tick in Table 1.1.1 and the cast alloys listed in Table 1.1.2.

1.1.6 Joining methods

(1) This Part covers the following joining methods:

- Arc welding (metal inert gas and tungsten inert gas)

- Fastening with threaded components

- Riveting

- Adhesive bonding

1.1.7 Environmental conditions

(1)P This Part covers structural applications exposed to normal atmospheric conditions and temperatures not exceeding +100°C (for fatigue purposes), including marine environments, except for adhesively bonded joints where the temperature limits apply to the range -20°C to 60°C. For aluminium alloy 5083 the data apply to maximum temperatures not exceeding 65°C. Fatigue strength data are not applicable to parts of the structure exposed to environments which are aggressively corrosive to the materials concerned.

(2) If these limits are exceeded resort may need to be made to test data and certification of fabrication technology.
