The outer surface shall be finished in white or bright metal.

(b) plastics drums and jerricans that

6.6.2.2.7 The materials of the portable tank, including any devices, gaskets, linings and accessories, shall not adversely affect the substances intended to be transported in the portable tank.

6.6.2.20.2 The following information shall be marked either on the portable tank itself or on a metal plate firmly secured to the portable tank

6.6.3.16.2 The following information shall be marked either on the portable tank itself or on a metal plate firmly secured to the portable tank

6.6.4.15.2 The following information shall be durably marked either on the portable tank itself or on a metal plate firmly secured to the portable tank.

For tanks

When for reasons of portable tank arrangements the plate cannot be permanently attached to the shell, the shell shall be marked with at least the information required by the pressure vessel code.

When for reasons of portable tank arrangements, the plate cannot be permanently attached to the shell, the shell shall be marked with at least the information required by the pressure vessel code.

4.2.1.13.9 For insulated portable tanks the capacity and setting of emergency relief device(s) shall be determined assuming a loss of insulation from 1 of the surface area.

Road tank vehicles, rail tank wagons, non metallic tanks and intermediate bulk containers (IBCs) are not considered to fall within the definition for portable tanks

(a) Portable tanks The tank shall be filled with water or any other non pressurized substance to approximately 97 of the tank volumetric capacity.

Shell material(s) and material standard reference(s)

Semi finished products are steel shapes (blooms, billets or slabs) that are later rolled into finished products such as beams bars or sheet.

(b) when leaking

6.6.3.2.5 The materials of the portable tank, including any devices, gaskets, and accessories, shall not adversely affect the non refrigerated liquefied gases intended for transport in the portable tank.

Road tank vehicles, rail tank wagons, non metallic tanks, intermediate bulk containers (IBCs), gas cylinders and large receptacles are not considered to fall within the definition for portable tanks

Portable Tanks

Portable tank materials shall be suitable for the external environment in which they may be transported.

4.2.1.9.1 Prior to filling, the shipper shall ensure that the appropriate portable tank is used and that the portable tank is not loaded with substances which in contact with the materials of the shell, gaskets, service equipment and any protective linings, are likely to react dangerously with them to form dangerous products or appreciably weaken the material.

4.2.3.6.1 Prior to filling the shipper shall ensure that the portable tank is approved for the refrigerated liquefied gas to be transported and that the portable tank is not loaded with refrigerated liquefied gases which in contact with the materials of the shell, gaskets and service equipment, are likely to react dangerously with them to form dangerous products or appreciably weaken the material.

6.6.2.2.3 Gaskets shall be made of materials not subject to attack by the substances intended to be transported.

Examples of test vessels are illustrated in Figure A5.1. Additional information may be obtained if the tank is mounted in a tray designed to collect any solids or liquids ejected.

6.6.3.14 Design approval

6.6.4.13 Design approval

For refrigerated liquefied gases, the escaping vapour shall be directed away from the tank and in such a manner that it cannot impinge upon the tank.

Major sectors affected are canned fruit and vegetables, beverages and tobacco.

This device shall also prevent an unacceptable amount of leakage of liquid in the case of overturning or entry of foreign matter into the tank.

4.2.2.7.1 Prior to filling the shipper shall ensure that the portable tank is approved for the non refrigerated liquefied gas to be transported and that the portable tank is not loaded with non refrigerated liquefied gases which in contact with the materials of the shell, gaskets and service equipment, are likely to react dangerously with them to form dangerous products or appreciably weaken the material.

If the SADT of the organic peroxide in the portable tank is 55 C or less, or the portable tank is constructed of aluminium, the portable tank shall be completely insulated.

The portable tank includes a shell fitted with service equipment and structural equipment necessary for the transport of gases.

The following information on the portable tank and organic peroxide is needed for the heating rate calculation
