4.1 General
The materials covered by this standard are to be used in a wide range of pressure equipment operating
over diverse range of both pressure and temperature. The range of applications extends from relatively
low pressure automotive equipment such as heat exchangers to heavy duty applications including
unfired pressure vessels and piping used in pressure equipment. !As a result, the standard covers an
extensive range of aluminium product forms, alloys and tempers as follows:"
— sheet, strip, plate and circles (EN 485, EN 941);

!If the pressure equipment is operating above room temperature for times exceeding 100 h, then the
long time behaviour of the material according to Annex B, Tables B.1 to B.4 will need to be taken into
consideration."
!Materials to be used for welded components shall be produced with a hydrogen level no greater
than 0,2 ml per 100 g aluminium, or an equivalent value/level determined by an alternative agreed
method."
4.2 Wrought products
!Applicable alloys and the chemical compositions for wrought products are given in Tables 1 and 2.
The chemical compositions of aluminium and aluminium alloys are specified in percentage by mass.
Limits for impurities are expressed as maxima that also will apply to alloying elements unless
expressed as a range. Aluminium is specified as a minimum for unalloyed aluminium, and as a
remainder for aluminium alloys."
!All grades of wrought aluminium and alloys shall have a lead (Pb), tin (Sn) and bismuth (Bi) content
not exceeding 0,015 0 % by mass, per each element. For particularly safety-sensitive applications (e.g.
high volumes at high pressure), lower values shall be agreed and stated on the order.
Wrought products in aluminium and aluminium alloys used for welded parts of pressure vessels that
are subjected to cold forming (e.g. rolled shells and heads) shall have a specified minimum A value after
fracture measured on a gauge length as follows:
LS= 5,65 (4.2-1)
oo
and ≥ 14 % in the longitudinal or transverse direction.
Wrought products in aluminium and aluminium alloys used for parts of pressure vessels that are not
subjected to cold forming (e.g. straight flanges and nozzles) shall have a specified minimum elongation
after fracture measured on a gauge length as follows:
LS= 5,65 (4.2-2)
oo
and ≥ 10 % in the longitudinal or transverse direction.
The conversion of A values into A and vice versa shall be carried out as specified in Annex C.
50
When using minimum A values converted from A values as requirements, the converted A value
50 50
shall be taken from Table C.1 then rounded up to the next whole number (example: a converted value
A of 12,2 % shall be implemented as a minimum requirement of A value by 13 %).

EXAMPLE 1 A 12,5 mm wide rectangular test piece prepared from rolled sheet with a thickness of 2,0 mm.
2
Then the cross sectional area of this test piece is 25 mm , and the corresponding gauge length for a proportional
test piece is 28,3 mm. The measured value of A is 13,0 % which corresponds to an approximate elongation
50
value for A of 17,0 %.
EXAMPLE 2 An elongation value for A of 24,0 % measured on a proportional test piece with a gauge length of
35,7 mm. This corres
