Repairs shall be consistent with the fabrication and testing requirements of the applicable design and
construction standards and are only permitted as indicated in the relevant periodic inspection
standards specified in chapter 6.2. Pressure receptacles, other than the jacket of closed cryogenic
receptacles, shall not be subjected to repairs of any of the following:
(a) weld cracks or other weld defects;
(b) cracks in walls;
(c) leaks or defects in the material of the wall, head or bottom.
Receptacles shall not be offered for filling:
(a) when damaged to such an extent that the integrity of the receptacle or its service equipment
may be affected;
(b) unless the receptacle and its service equipment has been examined and found to be in good
working order; and
(c) unless the required certification, retest, and filling marks are legible.
Filled receptacles shall not be offered for carriage:
(a) when leaking;
(b) when damaged to such an extent that the integrity of the receptacle or its service equipment
may be affected;
(c) unless the receptacle and its service equipment has been examined and found to be in good
working order; and
(d) unless the required certification, retest, and filling marks are legible.
Owners shall, on the basis of a reasoned request from the competent authority, provide it with all the
information necessary to demonstrate the conformity of the pressure receptacle in a language easily
understood by the competent authority. They shall cooperate with that authority, at its request, on any
action taken to eliminate non-conformity of the pressure receptacles which they own.
For UN pressure receptacles, the ISO standards listed below shall be applied. For other pressure
receptacles, the requirements of section 4.1.6 are considered to have been complied with if the
following standards, as relevant, are applied:

Special packing provisions for organic peroxides (Class 5.2) and self-reactive substances of Class 4.1
For organic peroxides, all receptacles shall be "effectively closed". Where significant internal pressure
may develop in a package by the evolution of a gas, a vent may be fitted, provided the gas emitted
will not cause danger, otherwise the degree of filling shall be limited. Any venting device shall be so
constructed that liquid will not escape when the package is in an upright position and it shall be able
to prevent ingress of impurities. The outer packaging, if any, shall be so designed as not to interfere
with the operation of the venting device.
Use of packagings (except IBCs)
Packagings for organic peroxides and self-reactive substances shall conform to the requirements of
Chapter 6.1 and shall meet its test requirements for packing group II.
The packing methods for organic peroxides and self-reactive substances are listed in packing
instruction 520 and are designated OP1 to OP8. The quantities specified for each packing method are
the maximum quantities authorized per package.
The packing methods appropriate for the individual currently assigned organic peroxides and selfreactive
substances are listed in 2.2.41.4 and 2.2.52.4.
For new organic peroxides, new self-reactive substances or new formulations of currently assigned
organic peroxides or self-reactive substances, the following procedure shall be used to assign the
appropriate packing method:
(a) ORGANIC PEROXIDE, TYPE B or SELF-REACTIVE SUBSTANCE, TYPE B:
Packing method OP5 shall be assigned, provided that the organic peroxide (or self-reactive
substance) satisfies the criteria of 20.4.3 (b) (resp. 20.4.2 (b)) of the Manual of Tests and
Criteria in a packaging authorized by the packing method. If the organic peroxide (or selfreactive
substance) can only satisfy these criteria in a smaller packaging than those authorized
by packing method OP5 (viz. one of the packagings listed for OP1 to OP4), then the
corresponding packing method with the lower OP number is assigned;
(b) ORGANIC PEROXIDE, TYPE C or SELF-REACTIVE SUBSTANCE, TYPE C:
Packing method OP6 shall be assigned, provided that the organic peroxide (or self-reactive
substance) satisfies the criteria of 20.4.3 (c) (resp. 20.4.2 (c)) of the Manual of Tests and
Criteria in a packaging authorized by the packing method. If the organic peroxide (or selfreactive
substance) can only satisfy these criteria in a smaller packaging than those authorized
by packing method OP6 then the corresponding packing method with the lower OP number is
assigned;
(c) ORGANIC PEROXIDE, TYPE D or SELF-REACTIVE SUBSTANCE, TYPE D:
Packing method OP7 shall be assigned to this type of organic peroxide or self-reactive
substance;
(d) ORGANIC PEROXIDE, TYPE E or SELF-REACTIVE SUBSTANCE, TYPE E:
Packing method OP8 shall be assigned to this type of organic peroxide or self-reactive
substance;
(e) ORGANIC PEROXIDE, TYPE F or SELF-REACTIVE SUBSTANCE, TYPE F:
Packing method OP8 shall be assigned to this type of organic peroxide or self-reactive
substance.
Use of intermediate bulk containers
The currently assigned organic peroxides specifically listed in packing instruction IBC520 may be
carried in IBCs in accordance with this packing instruction. IBCs shall conform to the requirements of
Chapter 6.5 and shall meet its test requirements for packing group II.
Other organic peroxides and self-reactive substances of type F may be carried in IBCs under
conditions established by the competent authority of the country of origin when, on the basis of the
appropriate tests, that competent authority is satisfied that such carriage may be safely conducted. The
tests undertaken shall include those necessary:
(a) To prove that the organic peroxide (or self-reactive substance) complies with the principles for
classification given in 20.4.3 (f) [resp. 20.4.2 (f)] of the Manual of Tests and Criteria, exit box
F of Figure 20.1 (b) of the Manual;
(b) To prove the compatibility of all materials normally in contact with the substance during
carriage;
(c) To determine, when applicable, the control and emergency temperatures associated with the
carriage of the product in the IBC concerned as derived from the SADT;
(d) To design, when applicable, pressure and emergency relief devices; and
(e) To determine if any special provisions are necessary for safe carriage of the substance.
If the country of origin is not a Contracting Party to ADR, the classification and transport conditions
shall be recognized by the competent authority of the first country Contracting Party to ADR reached
by the consignment.
