5.1.1 The designer shall select the materials to be used in the construction of the tank using ferritic steel,
austenitic steel, austenitic-ferritic stainless steel or aluminium alloy material standards published by a national
or international standards body or otherwise approved by the competent authority. The material shall in any
case meet the requirements specified in 5.2.
5.1.2 Materials used in the construction of shells shall be suitable for shaping. Materials shall be deemed
unsuitable if, even though they meet the material requirements of this European Standard, the degree of
shaping required by a particular shell design generates cracking or other signs of distress in the shell material.
5.1.3 Materials shall be used that are known to be resistant to brittle fracture and to stress corrosion
cracking.
5.1.4 When tested in accordance with the appropriate clauses of EN ISO 15614-1, the properties of
materials used in the fabrication of welded shells shall not be less than the minimum values specified for the
material selected in accordance with 5.1.1 throughout the welded area after welding without post-weld heat
treatment.

Ferritic steel materials shall be tested in accordance with EN ISO 148-1 using a V-shaped notch, and shall
2
have an impact strength of not less than 34 J/cm at –20 °C (or at the minimum design temperature where this
is lower). Impact tests shall be carried out on sheets of materials, or on their weld seams, where the sheet
thickness is more than 5 mm.
5.2.2 Yield strength, tensile strength and elongation after fracture
5.2.2.1 General

— the value of R used in the calculation does not exceed 1,15 multiplied by the value of R as specified for
e e
the material selected in accordance with the relevant standard for the material.
