RID/ADR allows that the listing of approved substances may be dispensed with. In such cases, according to RID/ADR, groups of substances permitted on the basis of the tank code shown in the rationalised approach in RID/ADR 4.3.4.1.2 should be accepted for carriage taking into account any relevant special provision. 5.3.2 If contact between the substance carried and the material used for the construction of the shell is deemed likely to entail a progressive decrease in the thickness of the walls, this thickness shall be increased at manufacture by an appropriate amount. NOTE This additional thickness, to allow for corrosion, is not taken into consideration in determining the minimum shell thickness (see 6.9.1). 5.3.3 If the shell is fitted with a non-metallic protective lining, only materials and their means of bonding to the shell that are known to remain leakproof shall be used. 5.3.4 If shells intended for the carriage of liquids having a flash-point of not more than 60 °C are fitted with non-conductive protective linings, precautions shall be taken to prevent the accumulation of electrostatic charges that could present a danger of ignition. NOTE This requirement is also applicable to UN No. 1361 carbon and UN No. 1361 carbon black, packing group II. 6 Design 6.1 General A shell may have a circular or a non-circular cross-section. 6.2 Design verification The design of a tank shall be verified in accordance with one or a combination of the following methods: a) for shells with a circular cross-section, EN 14025 or any one of the methods specified in Annex A; b) for shells with non-circular cross-sections: 1) dynamic testing (A.2); 2) finite element stress analysis (A.3); 3) reference design based on experience of the Competent Authority with existing tank designs (A.4); 4) calculation method (A.5). Documentation shall be produced that gives evidence of the design verification. The design shall in any case conform to the minimum requirements of this European Standard. SIST EN 13094:2008

(3) If the shell thickness is increased to allow for corrosive substances, this additional thickness shall not be taken into consideration in calculating the minimum shell thickness. The actual minimum thickness shall not be below the absolute minimum shown in Table 1. 6.9.2 Reduction of shell thickness 6.9.2.1 Where protection against damage of the shell is provided in accordance with 6.9.2.2 to 6.9.2.3, the minimum thickness may be reduced by a maximum of 2 mm of reference steel (or equivalent thickness in another material, calculated using equation 3) from that specified in 6.9.1, but shall not be below the absolute minimum shown in Table 1.

6.9.2.2 Tank vehicles and demountable tanks shall be deemed to be protected against damage when one of the following measures given in a) to i) is adopted; dimensions that refer to distances between strengthening elements shall be taken between their attachment points on the tank shell: a) For shells with a circular or elliptical cross-section having a maximum radius of curvature of 2 m, the shell is equipped with strengthening elements comprising partitions or surge plates, or external or internal rings, so placed that at least one of the following conditions is met:  the distance between two adjacent strengthening elements is less than or equal to 1,75 m;  the volume contained between two partitions or surge plates is less than or equal to 7 500 l. A ring, and associated shell shall have a section modulus of at least 10 cm3 in reference steel, or an equivalent section modulus in another metal (see 6.14.2.5), when calculated around the neutral axis parallel to the shell. External strengthening elements shall not have projecting edges with a radius of less than 2,5 mm. b) For shells with double walls having an intermediate layer of rigid solid material (e.g. foam, at least 50 mm thick), the outer wall has a thickness of at least 0,5 mm of mild steel, 0,8 mm of aluminium or 2 mm of fibre reinforced
plastic material. For other insulating materials (e.g. mineral-wool, at least 100 mm thick), the outer wall has a thickness of at least 0,8 mm of austenitic steel, the outer wall of the ends
may be of a fibre reinforced plastic material with a thickness of at least 3 mm. Other combinations of materials used to provide protection against damage shall have specific resilience, as determined in accordance with Annex B, equivalent to that of the minimum thickness required by 6.9.1, and the thickness of the inner wall of the combination shall be not less than the minimum value specified in 6.9.2.1. c) For shells of forms other than in a), the shell is provided all around the mid-point of its vertical height and over at least 30 % of its height with additional protection designed in such a way as to offer specific resilience, as determined in accordance with Annex B, at least equal to that of a shell constructed in reference steel of a thickness of 5 mm for a shell diameter not exceeding 1,80 m or 6 mm for a shell diameter exceeding 1,80 m. The additional protection shall be applied in a durable manner to the outside of the shell. This requirement shall be deemed to have been met without further proof of the specific resilience when
 the additional protection involves the welding of a plate of the same material as the shell to the area to be strengthened, such that the shell thickness is not less than the minimum specified in 6.9.1; and
 flanged ends to the full thickness are used with the additional side protection extending to cover at least one third of the flange length. SIST EN 13094:2008

For shells of forms other than in a), when applying requirements of global resilience, the following conditions are all met:  the volume contained between adjacent partitions or surge plates does not exceed 7 500 l;  the volume of any compartment does not exceed 15 000 l except in the case of tanks dedicated to the carriage of liquids at or above 100 °C and below their flashpoint;  the distance between adjacent partitions and surge plates does not exceed 1,75 m;  the average distance between adjacent partitions or surge plates does not exceed 1,4 m;  the corner radii connecting the side, top and bottom radii are not less than 250 mm;  the thickness of the ends are conform to d) or e) as appropriate;  for shells made with double ends with a separation exceeding 100 mm, the ends shall conform to the requirements specified in e);  the weakest 4 m-shell segment has a global resilience of at least 100 kN
