All valves through which the radioactive contents could escape shall be protected against
unauthorized operation.

The design of the package shall take into account ambient temperatures and pressures that are likely to
be encountered in routine conditions of carriage.

A package shall be so designed that it provides sufficient shielding to ensure that, under routine
conditions of carriage and with the maximum radioactive contents that the package is designed to
contain, the radiation level at any point on the external surface of the package would not exceed the
values specified in 2.2.7.2.4.1.2, 4.1.9.1.10 and 4.1.9.1.11, as applicable, with account taken of 7.5.11
CV33 (3.3) (b) and (3.5).

For radioactive material having other dangerous properties the package design shall take into account
those properties; see 2.1.3.5.3 and 4.1.9.1.5.

Manufacturers and subsequent distributors of packagings shall provide information regarding
procedures to be followed and a description of the types and dimensions of closures (including
required gaskets) and any other components needed to ensure that packages as presented for carriage
are capable of passing the applicable performance tests of this Chapter.

(Reserved)

Requirements for excepted packages

An excepted package shall be designed to meet the requirements specified in 6.4.2.

Requirements for Industrial packages

Types IP-1, IP-2, and IP-3 packages shall meet the requirements specified in 6.4.2 and 6.4.7.2.

A Type IP-2 package shall, if it were subjected to the tests specified in 6.4.15.4 and 6.4.15.5, prevent:
(a) Loss or dispersal of the radioactive contents; and
(b) More than a 20% increase in the maximum radiation level at any external surface of the
package.

A Type IP-3 package shall meet all the requirements specified in 6.4.7.2 to 6.4.7.15.

Alternative requirements for Types IP-2 and IP-3 packages

Packages may be used as Type IP-2 package provided that:
(a) They satisfy the requirements of 6.4.5.1;
(b) They are designed to satisfy the requirements prescribed for packing group I or II in Chapter
6.1; and
(c) When subjected to the tests required for packing groups I or II in Chapter 6.1, they would
prevent:
(i) Loss or dispersal of the radioactive contents; and
(ii) More than a 20% increase in the maximum radiation level at any external surface of the
package.

Portable tanks may also be used as Types IP-2 or IP-3 packages, provided that:
(a) They satisfy the requirements of 6.4.5.1;
(b) They are designed to satisfy the requirements prescribed in Chapter 6.7 and are capable of
withstanding a test pressure of 265 kPa; and
(c) They are designed so that any additional shielding which is provided shall be capable of
withstanding the static and dynamic stresses resulting from handling and routine conditions of
carriage and of preventing more than a 20% increase in the maximum radiation level at any
external surface of the portable tanks.

Tanks, other than portable tanks, may also be used as Types IP-2 or IP-3 packages for carrying LSA-I
and LSA-II liquids and gases as prescribed in Table 4.1.9.2.5, provided that:
(a) They satisfy the requirements of 6.4.5.1;
(b) They are designed to satisfy the requirements prescribed in Chapter 6.8; and
(c) They are designed so that any additional shielding which is provided shall be capable of
withstanding the static and dynamic stresses resulting from handling and routine conditions of
carriage and of preventing more than a 20% increase in the maximum radiation level at any
external surface of the tanks.
