heat.
47 Mixtures of solids that are not subject to
this subchapter and flammable liquids may
be transported under this entry without
first applying the classification criteria of
Division 4.1, provided there is no free liquid
visible at the time the material is loaded
or at the time the packaging or transport
unit is closed. Except when the liquids are
fully absorbed in solid material contained
in sealed bags, for single packagings, each
packaging must correspond to a design
type that has passed a leakproofness test
at the Packing Group II level. Small inner
packagings consisting of sealed packets
and articles containing less than 10 mL of
a Class 3 liquid in Packing Group II or III
absorbed onto a solid material are not subject to this subchapter provided there is no
free liquid in the packet or article.
48 Mixtures of solids that are not subject to
this subchapter and toxic liquids may be
transported under this entry without first
applying the classification criteria of Division 6.1, provided there is no free liquid
visible at the time the material is loaded
or at the time the packaging or transport
unit is closed. For single packagings, each
packaging must correspond to a design
type that has passed a leakproofness test
at the Packing Group II level. This entry
may not be used for solids containing a
Packing Group I liquid.
49 Mixtures of solids that are not subject to
this subchapter and corrosive liquids may
be transported under this entry without
first applying the classification criteria of
Class 8, provided there is no free liquid
visible at the time the material is loaded
or at the time the packaging or transport
unit is closed. For single packagings, each
packaging must correspond to a design
type that has passed a leakproofness test
at the Packing Group II level.
50 Cases, cartridge, empty with primer
which are made of metallic or plastic casings and meeting the classification criteria
of Division 1.4 are not regulated for domestic transportation.
51 This description applies to items previously described as  - Toy propellant devices, Class C -  and includes reloadable
kits. Model rocket motors containing 30
grams or less propellant are classed as Division 1.4S and items containing more than
30 grams of propellant but not more than
62.5 grams of propellant are classed as Division 1.4C.
52 This entry may only be used for substances that are too insensitive for acceptance into Class 1 (explosive) when tested in
accordance with Test Series 2 in the UN
Manual of Tests and Criteria, Part I (incor-

porated by reference; see Section 171.7 of this subchapter).
53 Packages of these materials must bear
the subsidiary risk label,  - EXPLOSIVE - ,
and the subsidiary hazard class/division
must be entered in parentheses immediately following the primary hazard class
in the shipping description, unless otherwise provided in this subchapter or
through an approval issued by the Associate Administrator, or the competent authority of the country of origin. A copy of
the approval shall accompany the shipping
papers.
54 Maneb or maneb preparations not meeting the definition of Division 4.3 or any
other hazard class are not subject to the

transported by motor vehicle, rail car, or
aircraft.
55 This device must be approved in accordance with Section 173.56 of this subchapter by the
Associate Administrator.
56 A means to interrupt and prevent detonation of the detonator from initiating the
detonating cord must be installed between
each electric detonator and the detonating
cord ends of the jet perforating guns before
the charged jet perforating guns are offered for transportation.
57 Maneb or Maneb preparations stabilized
against self-heating need not be classified
in Division 4.2 when it can be demonstrated by testing that a volume of 1 m3
of substance does not self-ignite and that
the temperature at the center of the sample does not exceed 200 SectionC, when the sample
is maintained at a temperature of not less
than 75 SectionC Section2 SectionC for a period of 24 hours, in
accordance with procedures set forth for
testing self-heating materials in the UN
Manual of Tests and Criteria (IBR, see
Section 171.7 of this subchapter).
58 Aqueous solutions of Division 5.1 inorganic solid nitrate substances are considered as not meeting the criteria of Division
5.1 if the concentration of the substances
in solution at the minimum temperature
encountered in transport is not greater
than 80% of the saturation limit.
59 Ferrocerium, stabilized against corrosion, with a minimum iron content of 10
percent is not subject to the requirements
of this subchapter.
61 A chemical oxygen generator is spent if
its means of ignition and all or a part of its
chemical contents have been expended.
62 Oxygen generators (see Section 171.8 of this subchapter) are not authorized for transportation under this entry.
64 The group of alkali metals includes lithium, sodium, potassium, rubidium, and
