1) Where values are quoted in bold greater thicknesses and/or higher mechanical properties may be permitted in some forms see ENs and prENs listed in 1.2.1.3. In this case the Rp0,2 and Rm values can be taken as f0 and fu. If using such higher values the corresponding HAZ-factors have to be calculated ace. to expression (6.13) and (6.14) with the same values for f0,haz and fu,haz.

2) Where minimum elongation values are given in bold, higher minimum values may be given for some forms or thicknesses.

3) According to EN 755-2: following rule applies: "If a profile cross-section is comprised of different thicknesses which fall in more than one set of specified mechanically property values, the lowest specified value should be considered as valid for the whole profile cross-section." Exception is possible and the highest value given may be used provided the manufacturer can support the value by an appropriate quality assurance certificate.

4) The HAZ-values are valid for MIG welding and thickness up to 15 mm. For TIG welding strain hardening alloys (Зххх, 5xxx and 8011 A) up to 6 mm the same values apply, but for TIG welding precipitation hardening alloys (6xxx and 7xxx) and thickness up to 6 mm the HAZ values have to be multiplied by a factor 0,8 and so the -factors. For higher thickness - unless other data are available - the HAZ values and -factors have to be further reduced by a factor 0,8 for the precipitation hardening alloys (6xxx and 7xxx) alloys and by a factor 0,9 for strain hardening alloys (Зххх, 5xxx and 8011 A). These reductions do not apply in temper O.

5)

6) ВС = buckling class, see 6.1.4.4, 6.1.5 and 6.3.1.

7)n-value in Ramberg-Osgood expression for plastic analysis. It applies only in connection with the listed f0-value (= minimum standardized value).

8) If it is intended to use extruded or extruded and drawn semi-products in EN AW-5454 or EN AW-5754 in tempers O/Hl 11 and F/Hl 12 or H14/H24/H34 according to EN 755-2 or EN 754-2, the corresponding values of table 3.2a may be applied for design with following changes:

- For EN AW-5454 temper O/Hl 11 (includes F/Hl 12) replace the values for/u and/u,haz by 200 N/mm2.

- For EN AW-5754 temper O/Hl 11 (includes F/Hl 12) replace the values for/u and/U;haz by 180 N/mm2 (thickness of bars < 150 mm).

- For EN AW-5754 temper H14/H24/H34 replace the values for f0 by 180 N/mm2 and for 0,haz by 0,56.
