specified in Column (9A) of the Section 172.101
Table or Section 175.75(c), the following aircraft
batteries may be transported on passenger
aircraft as cargo:
a. Wet cell batteries, UN 2794 or UN 2795,
up to a limit of 100kg net mass per package;
b. Lithium ion batteries, UN 3480, packages
containing a single aircraft battery with
a net mass not exceeding 35kg; and
c. Transport in accordance with this special provision must be noted on the shipping paper.
A53 Refrigerating machines and refrigerating machine components are not subject to the requirements of this subchapter
when containing less than 12 kg (26.4
pounds) of a non-flammable gas or when
containing 12 L (3 gallons) or less of ammonia solution (UN2672) (see Section 173.307 of this
subchapter).
A54 Irrespective of the quantity limits in
Column 9B of the Section 172.101 table, a lithium
battery, including a lithium battery
packed with, or contained in, equipment
that otherwise meets the applicable requirements of Section 173.185, may have a mass
exceeding 35 kg if approved by the Associate Administrator prior to shipment.
A56 Radioactive material with a subsidiary
hazard of Division 4.2, Packing Group I,
must be transported in Type B packages
when offered for transportation by aircraft. Radioactive material with a subsidiary hazard of Division 2.1 is forbidden
from transport on passenger aircraft.
A60 Sterilization devices, when containing
less than 30 mL per inner packaging with
not more than 150 mL per outer packaging,
may be transported in accordance with the
provisions in Section 173.4a, irrespective of
Section 173.4a(b), provided such packagings were
first subjected to comparative fire testing.
Comparative fire testing between a package as prepared for transport (including
the substance to be transported) and an
identical package filled with water must
show that the maximum temperature
measured inside the packages during testing does not differ by more than 200 SectionC (392
SectionF). Packagings may include a vent to permit the slow escape of gas (i.e. not more
than 0.1 mL/hour per 30 mL inner packaging at 20 SectionC (68 SectionF) produced from gradual decomposition. The requirements of
SectionSection 173.24(g)(1) and 173.27(c) do not apply.
A61 a. When used for purposes such as sterilization, inner packagings of peroxyacetic
acid, stabilized, classified as UN 3107 Organic peroxide type E, liquid or UN 3109 Organic peroxide type F, liquid may be fitted
with a vent consisting of hydrophobic
membrane, provided:

Section 172.102

(1) Each inner packaging contains not
more than 70 mL;
(2) The inner packaging is designed so that
the vent is not immersed in liquid in any
orientation;
(3) Each inner packaging is enclosed in an
intermediate rigid plastic packaging
with a small opening to permit release of
gas and contains a buffer that neutralizes the contents of the inner packaging
in the event of leakage;
(4) Intermediate packagings are packed in
a fiberboard box (4G) outer packaging;
(5) Each outer packaging contains not
more than 1.4 L of liquid; and
(6) The rate of oxygen release from the
outer packaging does not exceed 15 mL
per hour.
b. Such packages must be transported on
cargo aircraft only. The requirements of
SectionSection 173.24(g)(1) and 173.27(c) do not apply.
A82 The quantity limits in columns (9A)

A101 In addition to the applicable requirements of Section 173.185, the quantity of lithium
metal in the batteries contained in any
piece of equipment must not exceed 12 g
per cell and 500 g per battery.
A105 The total net quantity of dangerous
goods contained in one package, excluding
magnetic material, must not exceed the
following:
a. 1 kg (2.2 pounds) in the case of solids;
b. 0.5 L (0.1 gallons) in the case of liquids;
c. 0.5 kg (1.1 pounds) in the case of Division
2.2 gases; or
d. any combination thereof.
A112 Notwithstanding the quantity limits
shown in Column (9A) and (9B) for this
entry, the following IBCs are authorized
for transportation aboard passenger and
cargo-only aircraft. Each IBC may not exceed a maximum net quantity of 1,000 kg:
a. Metal: 11A, 11B, 11N, 21A, 21B and 21N
b. Rigid plastics: 11H1, 11H2, 21H1 and 21H2
c. Composite with plastic inner receptacle:
11HZ1, 11HZ2, 21HZ1 and 21HZ2
d. Fiberboard: 11G
e. Wooden: 11C, 11D and 11F (with inner liners)
f. Flexible: 13H2, 13H3, 13H4, 13H5, 13L2,
13L3, 13L4, 13M1 and 13M2 (flexible IBCs
must be sift-proof and water resistant or
must be fitted with a sift-proof and water
resistant liner).
A189 Except where the defining criteria of
another class or division are met, concentrations of formaldehyde solution:
