slatted crates), or on pallets or other handling devices, instead of
packages meeting the UN performance packaging requirements in
paragraphs (b)(3)(ii) and (iii) of this section. The battery must be
secured to prevent inadvertent shifting, and the terminals may not
support the weight of other superimposed elements;

    Note 1 to paragraph (a)(2): ``Filling density'' means the
percent ratio of the weight of gas in a packaging to the weight of
water that the container will hold at 16 [deg]C (60 [deg]F). (1 lb.
of water = 27.737 in\3\ at 60 [deg]F).

    Note 2 to paragraph (a)(2): Cylinders purchased after Oct. 1,
1944, for the transportation of chlorine must contain no aperture
other than that provided in the neck of the cylinder for attachment
of a valve equipped with an approved pressure relief device.
Cylinders purchased after November 1, 1935, and filled with chlorine
may not contain over 68.04 kg (150 lb.) of gas.

    Note 4 to paragraph (a)(2): Special carbon dioxide mining
devices containing a heating element and filled with not over 2.72
kg (6 lb.) of carbon dioxide may be filled to a density of not over
85 percent, provided the cylinder is made of steel with a calculated
bursting pressure in excess of 39,000 psig, fitted with a frangible
disc that will operate at not over 57 percent of that pressure, and
is able to withstand a drop of 10 feet when striking crosswise on a
steel rail while under a pressure of at least 3,000 psig. Such
devices must be shipped in strong boxes or must be wrapped in heavy
burlap and bound by 12-gauge wire with the wire completely covered
by friction tape. Wrapping must be applied so as not to interfere
with the functioning of the frangible disc pressure relief device.
Shipments must be described as ``liquefied carbon dioxide gas
(mining device)'' and marked, labeled, and certified as prescribed
for liquefied carbon dioxide.

    Note 5 to paragraph (a)(2): All parts of the valve and pressure
relief devices in contact with contents of cylinders must be of a
metal or other material, suitably treated, if necessary, that will
not cause the formation of any acetylides.

    Note 7 to paragraph (a)(2): Specification 3HT cylinders for
aircraft use only, having a maximum service life of 24 years.
Authorized only for nonflammable gases. Cylinders must be equipped
with pressure relief devices of the frangible disc type that meet
the requirements of Sec.  173.301(f). Each frangible disc must have
a rated bursting pressure that does not exceed 90 percent of the
minimum required test pressure of the cylinder. Discs with fusible

    (c) * * *

Table 1 to Paragraph (c)

* * * * *

    Notes to table 1 to paragraph (c):  1. The filling density
percentage for liquefied gases is hereby defined as the percent
ratio of the mass of gas in the tank to the mass of water that the
tank will hold. For determining the water capacity of the tank in
kilograms, the mass of 1 L of water at 15.5 [deg]C in air is 1 kg
(the mass of one gallon of water at 60 [deg]F in air is 8.32828
pounds).
    2. The liquefied gas must be loaded so that the outage is at
least two percent of the total capacity of the tank at the reference
temperature of 46 [deg]C (115 [deg]F) for a non-insulated tank; 43
[deg]C (110 [deg]F) for a tank having a thermal protection system
incorporating a metal jacket that provides an overall thermal
conductance at 15.5 [deg]C (60 [deg]F) of no more than 10.22
kilojoules per hour--per square meter--per degree Celsius (0.5 Btu
per hour/per square foot/per degree F) temperature differential; and
41 [deg]C (105 [deg]F) for an insulated tank having an insulation
system incorporating a metal jacket that provides an overall thermal
conductance at 15.5 [deg]C (60 [deg]F) of no more than 1.5333
kilojoules per hour--per square meter--per degree Celsius (0.075 Btu
per hour/per square foot/per degree F) temperature differential.
    3. The requirements of Sec.  173.24b(a) apply.
    4. The gas pressure at 54.44 [deg]C (130 [deg]F) in any non-
insulated tank car may not exceed 7/10 of the marked test pressure,
except that a tank may be charged with helium to a pressure of 10
percent in excess of the marked maximum gas pressure at 54.44 [deg]C
(130 [deg]F) of each tank.
    5. The liquid portion of the gas at -17.77 [deg]C (0 [deg]F)
must not completely fill the tank.
    6. The maximum permitted filling density is 125 percent. The
quantity of chlorine loaded into a single unit-tank car may not be
loaded in excess of the normal lading weights nor in excess of 81.65
Mg (90 tons).
    7. 89 percent maximum to 80.1 percent minimum at a test pressure
of 6.2 bar (90 psig).
    8. 59.6 percent maximum to 53.6 percent minimum at a test
pressure of 7.2 bar (105 psig).
    9. For a liquefied petroleum gas, the liquefied gas must be
loaded so that the outage is at least one percent of the total
capacity of the tank at the reference temperature of 46 [deg]C (115
[deg]F) for a non-insulated tank; 43 [deg]C (110 [deg]F) for a tank
having a thermal protection system incorporating a metal jacket that
provides an overall thermal conductance at 15.5 [deg]C (60 [deg]F)
of no more than 10.22 kilojoules per hour--per square meter--per
degree Celsius (0.5 Btu per hour/per square foot/per degree F)
temperature differential; and 41 [deg]C (105 [deg]F) for an
insulated tank having an insulation system incorporating a metal
jacket that provides an overall thermal conductance at 15.5 [deg]C
(60 [deg]F) of no more than 1.5333 kilojoules per hour--per square
meter--per degree Celsius (0.075 Btu per hour/per square foot/per
degree F) temperature differential.
    10. For liquefied petroleum gas and anhydrous ammonia, during
the months of November through March (winter), the following
reference temperatures may be used: 38 [deg]C (100 [deg]F) for a
non-insulated tank; 32 [deg]C (90 [deg]F) for a tank having a
thermal protection system incorporating a metal jacket that provides
an overall thermal conductance at 15.5 [deg]C (60 [deg]F) of no more
than 10.22 kilojoules per hour--per square meter--per degree Celsius
(0.5 Btu per hour/per square foot/per degree F) temperature
differential; and 29 [deg]C (85 [deg]F) for an insulated tank having
an insulation system incorporating a metal jacket and insulation
that provides an overall thermal conductance at 15.5 [deg]C (60
[deg]F) of no more than 1.5333 kilojoules per hour--per square
meter--per degree Celsius (0.075 Btu per hour/per square foot/per
degree F) temperature differential. The winter reference
temperatures may only be used for a tank car shipped directly to a
consumer for unloading and not stored in transit. The offeror of the
tank must inform each customer that the tank car was filled based on
winter reference temperatures. The tank must be unloaded as soon as
possible after March in order to retain the specified outage and to
prevent a release of hazardous material, which might occur due to
the tank car becoming liquid full at higher temperatures.
    11. For materials poisonous by inhalation, until December 31,
2027, the single unit tank car tanks authorized are only those cars
approved by the Tank Car Committee for

transportation of the specified material and built prior to March
16, 2009. After December 31, 2027, all single unit tank cars used in
PIH/TIH service must meet the requirements of Note 12.
    12. Except as provided in paragraph (d) of this section, for
materials poisonous by inhalation, fusion-welded tank car tanks
built on or after March 16, 2009, used for the transportation of the
PIH materials noted, must meet the applicable authorized tank car
specification and must be equipped with a head shield as prescribed
in Sec.  179.16(c)(1).
