Hazardous Materials Regulations: Minor Editorial Corrections and 
Clarifications

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA), 
DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This final rule corrects editorial errors, makes minor 
regulatory changes and, in response to requests for clarification, 
improves the clarity of certain provisions in the Hazardous Materials 
Regulations (HMR). The intended effect of this rule is to enhance the 
accuracy and reduce misunderstandings of the regulations. The 
amendments contained in this rule are non-substantive changes that do 
not impose new requirements.

DATES: Effective date: October 1, 2007.

FOR FURTHER INFORMATION CONTACT: Dirk Der Kinderen, Office of Hazardous 
Materials Standards, (202) 366-8553, PHMSA, East Building, PHH-10, 1200 
New Jersey Avenue, SE., Washington, DC 20590.

SUPPLEMENTARY INFORMATION:

I. Background

    PHMSA annually reviews the Hazardous Materials Regulations (HMR; 49 
CFR parts 171-180) to identify typographical and other errors, outdated 
addresses or other contact information, and similar errors. In this 
final rule, we are correcting typographical errors; incorrect CFR 
references and citations; inaccurate office names; inconsistent use of 
terminology; misstatements of certain regulatory requirements; and 
inadvertent omissions of information. In addition, this final rule 
revises the address for PHMSA to indicate the new location for the 
headquarters office.
    Because these amendments do not impose new requirements, notice and 
public comment procedures are unnecessary. By making these amendments 
effective without the customary 30-day delay following publication, the 
changes will appear in the next revision of Title 49.
    The following is a summary by section of the major changes made in 
this final rule. The summary does not include minor editorial 
corrections such as punctuation errors, or similar minor revisions.

II. Section-by-Section Review

Part 107

Section 107.608
    This section contains general requirements for registration. In 
paragraph (a), we are removing the reference to Sec.  107.616(d) for 
consistency with revisions made in HM-208F (72 FR 24536; May 3, 2007). 
The HM-208F final rule removed paragraph (d) of Sec.  107.616.

Part 171

Section 171.6
    This section lists approved collections of information required 
under the HMR. In the table in paragraph (b)(2), in the third column 
for OMB control number 2137-0557, we are removing the reference 
citations to Sec. Sec.  178.270-3 and 178.270-13. Section 178.270-3 was 
removed in an earlier rulemaking, and we are removing Sec.  178.270-13, 
which addresses testing requirements for IM 101 and 102 specification 
portable tanks in this final rule. As prescribed in Sec.  173.32(c)(2), 
the manufacture of these portable tanks is no longer authorized.
Section 171.7
    This section lists material incorporated by reference into the HMR. 
In paragraph (a)(3), in the second column of the table of material 
incorporated by reference, for the entry ASME Code, Sections II (Parts 
A and B), V, VIII (Division 1), and IX, we are removing the reference 
citations, Sec. Sec.  178.270-2 through 178.272-1, which contain 
requirements applicable to the manufacture of IM 101 and 102 portable 
tanks, because the manufacture of these portable tanks is no longer 
authorized. Additionally, we are updating a reference citation for the 
use of the UN Recommendations.
Section 171.8
    This section lists definitions for terms used in the HMR. In the 
definition for ``Administrator,'' we are correcting the office name 
``Research and Special Programs Administration'' to read ``Pipeline and 
Hazardous Materials Safety Administration.'' In the

[[Page 55679]]

definition for ``Shipping paper,'' we are removing the references to 
``Sec. Sec.  172.202, 172.203 and 172.204'' to clarify that shipping 
papers must be prepared in accordance with the requirements in subpart 
C of part 172.
Section 171.14
    This section provides transitional provisions for recently adopted 
regulatory changes. In paragraph (d)(6), we are correcting the citation 
``172.202(a)(6)'' to read ``172.202(a)(7)'' for consistency with 
revisions made to Sec.  173.202(a) in a final rule published under 
docket number HM-215I (71 FR 78596; December 29, 2006).
Section 171.15
    This section contains telephonic notification requirements for 
certain hazardous materials transportation incidents. In paragraph 
(b)(3), we are correcting the telephone report requirements for 
infectious substances by removing the term ``diagnostic specimen'' 
since that term no longer appears in the HMR.
Section 171.23
    This section contains requirements for specific materials and 
packages transported under the international standards. In paragraph 
(b)(5), we are correcting requirements by removing an inaccurate 
exception for Class 7 (radioactive) materials included in a final rule 
published under docket number HM-215F (72 FR 25162; May 3, 2007).

Part 172

Section 172.101--The Hazardous Materials Table (HMT)
    We are removing the entries ``Helium-oxygen mixture, see Rare gases 
and oxygen mixtures,'' ``Nitrogen, mixtures with rare gases, see Rare 
gases and nitrogen mixtures,'' and ``Oxygen, mixtures with rare gases, 
see Rare gases and oxygen mixtures.'' These entries are being removed 
for consistency with revisions made in the final rule published under 
docket number HM-215I.
    We are correcting entries in the HMT as follows:
     For the entries ``Ammonia, anhydrous,'' Division 2.3, 
UN1005, ``Ammonia solution, relative density less than 0.880 at 15 
degrees C in water, with more than 50 percent ammonia,'' Division 2.3, 
UN3318, and ``Ammonia solutions, relative density less than 0.880 at 15 
degrees C in water, with more than 35 percent but not more than 50 
percent ammonia,'' UN2073, we are correcting Column (7) by adding 
``N87.'' Special provision ``N87'' was inadvertently omitted. This 
correction appears as a ``Remove/Add'' in this rulemaking.
     For the entry ``Articles, explosive, n.o.s.,'' UN0353, in 
Column (6), we are correcting the label code ``1.4GD'' to read 
``1.4G.''
     For the entry ``Articles, explosive, n.o.s.,'' UN0467I, in 
Column (4), we are correcting the identification number to read 
``UN0467'' and in Column (5), we are correcting the packing group to 
read ``II.'' This correction appears as a ``Remove/Add'' in this 
rulemaking.
     For the entry ``Caesium hydroxide solution,'' UN2681, PG 
III, in Column (8B), we are correcting the section reference to read 
``203.''
     For the entry ``Contrivances, water-activated, with 
burster, expelling charge or propelling charge,'' UN0248, we are 
correcting Column (1) by adding ``G.'' Symbol ``G'' was inadvertently 
omitted.
     For the entry ``Contrivances, water-activated, with 
burster, expelling charge or propelling charge,'' UN0249, we are 
correcting Column (1) by adding ``G.'' Symbol ``G'' was inadvertently 
omitted.
     For the entry ``Hydrazine, aqueous solution, with more 
than 37% hydrazine, by mass,'' UN2030, PG III, in Column (8A), we are 
correcting the section reference to read ``154.''
     For the entry ``Hydrogendifluorides, solid, n.o.s.,'' 
UN1740, PG II and III, the proper shipping name is corrected to the 
singular form to read ``Hydrogendifluoride, solid, n.o.s.'' This 
correction appears as a ``Remove/Add'' in this rulemaking.
     For the entry ``Hydrogen peroxide, aqueous solutions with 
more than 40 percent but not more than 60 percent hydrogen peroxide 
(stabilized as necessary,) '' UN2014, we are correcting Column (7) by 
adding ``A60.'' Special provision ``A60'' was inadvertently omitted.
     For the entry ``Hydrogen peroxide, aqueous solutions with 
not less than 8 percent but less than 20 percent hydrogen peroxide 
(stabilized as necessary,) '' UN2984, in Column (8C), we are correcting 
the section reference to read ``241.''
     For the entry ``Nitrocellulose, with not more than 12.6 
percent nitrogen, by dry mass, or Nitrocellulose mixture with pigment 
or Nitrocellulose mixture with plasticizer or Nitrocellulose mixture 
with pigment and plasticizer,'' UN2557, we are revising the proper 
shipping name in column (2) to read ``Nitrocellulose, with not more 
than 12.6 percent, by dry mass mixture with or without plasticizer, 
with or without pigment.'' This revision is being made for consistency 
with the description for UN2557 in the UN Recommendations, and appears 
as a ``Remove/Add'' in this rulemaking.
     For the entry ``4-Nitrophenylhydrazine, with not less than 
30% water, by mass,'' UN3376, in Column (7) we are correcting Special 
provision ``164'' to read ``162.'' Special provision ``164'' was 
inadvertently assigned in place of ``162.'' This correction appears as 
a ``Remove/Add'' in this rulemaking.
     For the entry ``Organoarsenic compound, liquid, n.o.s.,'' 
UN3280, PG I, II, and III, the information in the columns associated 
with PG I is corrected by aligning the hazardous material information 
with the appropriate columns. This correction appears as a ``Remove/
Add'' in this rulemaking.
     For the entry ``Paint or Paint related materials,'' 
UN3066, PG II and III, the proper shipping name is corrected to the 
singular form to read ``Paint or Paint related material.'' This 
correction appears as a ``Remove/Add'' in this rulemaking.
Section 172.202
    Section 172.202 contains requirements for shipping descriptions on 
shipping papers. In paragraph (a)(6)(vi), we are correcting the wording 
``except for UN2800, UN3072, and UN3166'' to read ``except for UN2800, 
UN2807, UN3072, UN3166 and UN3171'' for consistency with the preamble 
discussion to Sec.  172.202(a) in the final rule published under docket 
number HM-215I.
Section 172.302
    This section establishes general marking requirements for bulk 
packaging. In paragraph (f), we are revising the last sentence to 
clarify the example illustrating a circumstance for which a bulk 
packaging need not be remarked to conform to revisions made in the 
shipping name of the material it contains.
Section 172.303
    This section addresses prohibited marking. In paragraph (a), we are 
adding the clarifying language ``or any other markings indicating that 
the material is hazardous (e.g., RQ, INHALATION HAZARD)'' for 
consistency with the language used elsewhere in the HMR.
Section 172.505
    This section sets forth requirements for placarding for subsidiary 
hazards. In paragraph (a), we are correcting the reference ``Sec.  
172.203(m)(2)'' to read ``Sec.  172.203(m).'' Paragraphs (m)(1) and 
(m)(2) were combined into a single paragraph (m) in a final rule 
published

[[Page 55680]]

under docket number HM-189Y (70 FR 56804; September 23, 2005).

Part 173

Section 173.6
    This section establishes exceptions from certain HMR requirements 
for materials of trade. In paragraph (a)(4), we are correcting the word 
``movement'' to read ``shifting'' for consistency with the language 
used in paragraphs (b)(1) and (b)(3).
Section 173.22
    This section sets forth general shipper responsibilities. In 
paragraph (c)(2), we are removing the acronym ``PHMSA'' following the 
wording ``Associate Administrator,'' because it is unnecessary. Section 
171.8 defines the term ``Associate Administrator'' to mean the 
Associate Administrator for Hazardous Materials Safety, Pipeline and 
Hazardous Materials Safety Administration.
Section 173.31
    This section establishes requirements for the use of railroad tank 
cars. Paragraph (g) of this section addresses tank car loading and 
unloading requirements. In paragraph (g)(1), we are revising the 
wording ``unloader'' to read ``each hazmat employee who is responsible 
for loading or unloading'' to clarify that the requirements of this 
section apply to both loading and unloading operations. In addition, we 
are correcting the wording ``blocked'' to read ``locked.'' In paragraph 
(g)(2), we are revising the language regarding the design and display 
of caution signs for consistency with the language used in Sec.  
174.67(a)(4).
Section 173.132
    This section contains classification criteria for Division 6.1 
materials. In the HM-215I final rule, we revised the toxicity criteria 
for Division 6.1 materials in Sec.  173.133 to be consistent with the 
toxicity criteria adopted in the United Nations Recommendations on the 
Transport of Dangerous Goods (UN Recommendations). However, the 
Division 6.1 definition in Sec.  173.132(a) was overlooked. Therefore, 
in paragraph (a), we are revising the definition of oral toxicity and 
inhalation toxicity to be consistent with our earlier amendments to 
Sec.  173.133. Also, in paragraph (a)(1)(iii)(B), we are correcting the 
measurement unit ``mL/mm\3\ '' to read ``mL/m\3\.''
Section 173.134
    This section contains classification criteria and establishes 
exceptions from certain HMR requirements for Division 6.2 materials. In 
paragraph (a)(8), we are correcting the wording ``diagnostic specimen'' 
to read ``patient specimen'' for consistency with changes made in a 
final rule published under docket number HM-226A (71 FR 32244; July 6, 
2006).
Sections 173.150, 173.151, 173.152, and 173.154
    These sections establish exceptions from certain HMR requirements 
for Class 3, Class 4, Division 5.1, Division 5.2, and Class 8 
materials. We are revising the limited quantity provisions in each of 
these sections to clarify that the labeling exception is not granted to 
materials with a Division 6.1 subsidiary hazard. The amendments 
disallowing the labeling exception for limited quantities of Division 
6.1 materials were included in a final rule under docket number HM-215G 
(69 FR 76044; December 20, 2004), but were inadvertently omitted when 
these provisions were revised under HM-228 (71 FR 14586; March 22, 
2006).
    Additionally, in Sec.  173.150(d)(2) pertaining to the carriage of 
alcoholic beverages as checked or carry-on baggage, we are correcting 
the reference ``175.10(a)(17)'' to read ``Sec.  175.10(a)(4).''
Section 173.199
    This section establishes packaging requirements for Category B 
infectious substances. In paragraph (a) introductory text, we are 
correcting an obsolete section reference.
Section 173.225
    This section sets forth packaging requirements for organic 
peroxides. In paragraph (c), we are removing ``>='' from Note 17 of the 
Organic Peroxide Table and adding ``< ='' to correct a typographical 
error.
Section 173.244
    This section sets forth bulk packaging requirements for certain 
Division 4.2, 4.3, and 6.1 materials. We are adding a sentence to the 
end of paragraph (c) to clarify DOT 51 and UN portable tanks used to 
transport Division 6.1 liquids, Hazard Zone A or B, must be certified 
and stamped to the ASME Code as prescribed in Sec.  178.273(b)(6).
Section 173.411
    This section establishes requirements for industrial packaging used 
to transport Class 7 materials. In paragraph (b)(5), we are removing 
the section citations to Sec. Sec.  178.270, 178.271, and 178.272 
because the manufacture of portable tanks to the IM 101 and 102 
specifications is no longer authorized.

Part 174

Section 174.67
    Section 174.67 prescribes procedures for conducting transloading 
operations involving railroad tank cars. In paragraphs (a)(2), (a)(3), 
and (a)(4), we are revising the wording ``the unloader'' to read ``each 
hazmat employee who is responsible for unloading'' for clarity. Also, 
in a final rule published under docket number HM-223 (68 FR 61941; 
October 30, 2003), we redesignated paragraph (a)(4) containing 
precautions when venting a tank car as paragraph (a)(6) but failed to 
include the newly redesignated paragraph in the regulatory text. 
Paragraph (a)(6) is added in this final rule.

Part 175

Section 175.8
    This section contains exceptions from certain HMR requirements for 
operator equipment and replacement items transported by aircraft. In 
paragraph (a)(3)(ii), we are correcting the reference ``Sec.  
175.75(a)'' to read ``Sec.  175.75(c)''.
Section 175.75
    This section establishes cargo limitation and stowage requirements 
for hazardous materials transported by aircraft. At the end of 
paragraph (e)(3), we are removing the word ``and'' and adding a period. 
The requirements in paragraphs (e)(3) and (e)(4) are stand-alone 
requirements. Paragraph (e)(3), which outlines conditions for hazardous 
materials transported on board a cargo aircraft, includes a requirement 
for written approval by FAA. Paragraph (e)(4), which outlines 
conditions for hazardous materials transported on board a small, single 
pilot, cargo aircraft, does not include a requirement for FAA approval.
    Also, in paragraph (e)(5), we are revising the ``Quantity and 
Loading Tables'' to correct the formatting errors.

Part 176

Section 176.83
    We are reprinting the ``Segregation of Cargo Transport Units on 
Board Hatchless Container Ships'' table in Sec.  176.83(l) to correct 
formatting errors.

Part 178

Sections 178.270-12, 178.270-13, and 178.270-14
    These sections establish requirements for IM 101 and 102 portable 
tanks. Most sections applicable to these portable tanks were removed 
from the HMR in a final rule under docket number HM-189Z (71 FR 54388; 
September 14, 2006) because the manufacture of IM portable

[[Page 55681]]

tanks is no longer authorized. These sections were inadvertently not 
omitted from that final rule.
Section 178.273
    This section sets forth requirements for approval of specification 
IM portable tanks and UN portable tanks. We are revising the section 
title and paragraph (e)(1) to remove references to the IM portable 
tanks because manufacture of those tanks is no longer authorized. Also, 
in paragraph (b)(7)(ii), we are removing the wording ``Sec.  178.270-14 
of this subchapter for IM portable tanks, Sec.  178.245-6 for 
Specification 51 steel portable tanks, or''.
Section 178.274
    This section contains specifications for UN portable tanks. We are 
revising paragraph (b)(1) to clarify that portable tanks used for Zone 
A or B toxic by inhalation liquids are required to have an ASME 
certification and U stamp as prescribed in Sec.  178.273(b)(6).
Section 178.348-4
    This section specifies pressure relief requirements for DOT 412 
cargo tanks. In paragraph (d)(3), we are removing a reference to a 
formula in obsolete Sec.  178.270-11(d)(3) and inserting the formula, 
expressed in nonmetric units, that had been contained in the referenced 
section. Section 178.270-11 was removed in a final rule under docket 
number HM-189Z.
Section 178.606
    This section establishes requirements for performing the stacking 
test to ensure that non-bulk packagings conform to the performance 
standard established in the HMR. In paragraph (c)(2)(ii), in the 
stacking test requirements for a packaging intended for solids, we are 
correcting the formula to include a constant of 2.2 (lbs/kg) to convert 
the units on the right side of the formula to pounds for consistency 
with the units of variable ``A'' in the formula. In addition, we are 
including explanations of the multipliers ``2.2'' and ``.98'' in the 
formula for liquids.

Part 179

Section 179.300-19
    This section addresses inspection requirements for newly 
constructed rail tank cars. In paragraph (a), we are revising the 
wording ``acceptable to the Bureau of Explosives'' to read ``as 
approved by the Associate Administrator for Safety, FRA.'' These 
approvals are no longer handled by the Bureau of Explosives.

Part 180

Section 180.209
    This section establishes requalification requirements for 
cylinders. In the table in paragraph (i)(1), we are correcting ``3 to 
20 years'' to read ``5 to 20 years'' for the initial porous filler 
requalification of acetylene cylinders manufactured on or after January 
1, 1991. The change from 3 years to 5 years, adopted in a final rule 
published under docket number HM 218B, is correctly stated in footnote 
2 following the table.
Section 180.212
    This section specifies requirements for repair of seamless DOT 
specification and UN cylinders. In paragraph (b)(2), we are revising 
the wording to clarify that rethreading of cylinders may be performed 
by a manufacturer of the type of cylinder being rethreaded instead of 
limiting the work to the original manufacturer, who may no longer be in 
business. This revised wording is consistent with the wording used in 
paragraph (b)(1).
Section 180.215
    This section establishes reporting and record-retention 
requirements related to the qualification, maintenance, and use of 
cylinders. We are correcting paragraph (b) by adding the words ``, if 
present'' after ``manufacturer's name or symbol'' to alleviate 
confusion by cylinder requalifiers.

III. Regulatory Analyses and Notices

A. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This final rule is not considered a significant regulatory action 
under section 3(f) of Executive Order 12866 and, therefore, was not 
reviewed by the Office of Management and Budget. This rule is not 
significant under the Regulatory Policies and Procedures of the 
Department of Transportation (44 FR 11034). This final rule does not 
impose new or revised requirements for hazardous materials shippers or 
carriers; therefore, it is not necessary to prepare a regulatory impact 
analysis.

B. Executive Order 13132

    This final rule has been analyzed in accordance with the principles 
and criteria in Executive Order 13132 (``Federalism''). This final rule 
does not adopt any regulation that: (1) Has substantial direct effects 
on the States, the relationship between the national government and the 
States, or the distribution of power and responsibilities among the 
various levels of government; or (2) imposes substantial direct 
compliance costs on State and local governments. PHMSA is not aware of 
any State, local or Indian tribe requirements that would be preempted 
by correcting editorial errors and making minor regulatory changes. 
This final rule does not have sufficient federalism impacts to warrant 
the preparation of a federalism assessment.

C. Executive Order 13175

    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 13175 (``Consultation and 
Coordination with Indian Tribal Governments''). Because this final rule 
does not have tribal implications, does not impose substantial direct 
compliance costs on Indian tribal governments, and does not preempt 
tribal law, the funding and consultation requirements of Executive 
Order 13175 do not apply, and a tribal summary impact statement is not 
required.

D. Regulatory Flexibility Act, Executive Order 13272, and DOT 
Procedures and Policies

    I certify that this final rule will not have a significant economic 
impact on a substantial number of small entities. This rule makes minor 
editorial changes which will not impose any new requirements on persons 
subject to the HMR; thus, there are no direct or indirect adverse 
economic impacts for small units of government, businesses or other 
organizations.

E. Unfunded Mandates Reform Act of 1995

    This rule does not impose unfunded mandates under the Unfunded 
Mandates Reform Act of 1995. It does not result in costs of $120.7 
million or more to either State, local, or tribal governments, in the 
aggregate, or to the private sector, and is the least burdensome 
alternative that achieves the objective of the rule.

F. Paperwork Reduction Act

    There are no new information collection requirements in this final 
rule.

G. Environmental Impact Analysis

    There are no environmental impacts associated with this final rule.

H. Regulation Identifier Number (RIN)

    A regulation identifier number (RIN) is assigned to each regulatory 
action listed in the Unified Agenda of Federal Regulations. The 
Regulatory Information Service Center publishes the Unified Agenda in 
April and October of each year. The RIN number contained in the

[[Page 55682]]

heading of this document can be used to cross-reference this action 
with the Unified Agenda.

    (3) Each hazmat employee who is responsible for unloading must 
secure access to the track to prevent entry by other rail equipment, 
including motorized service vehicles. This requirement may be satisfied 
by lining each switch providing access to the unloading area against 
movement and securing each switch with an effective locking device, or 
by using derails, portable bumper blocks, or other equipment that 
provides and equivalent level of safety.
    (4) Each hazmat employee who is responsible for unloading must 
display caution signs on the track or on the tank cars to warn persons 
approaching the cars from the open end of the track and must be left up 
until after all closures are secured and the cars are in proper 
condition for transportation. The caution signs must be of metal or 
other durable material, rectangular, at 30.48 cm (12 inches) high by 
38.10 cm (15 inches) wide, and bear the word ``STOP.'' The word 
``STOP'' must appear in letters at least 10.16 cm (4 inches) high. The 
letters must be white on a blue background. Additional words, such as 
``Tank Car Connected'' or ``Crew at Work,'' may also appear in white 
letters under the word ``STOP.''
* * * * *
    (6) Before a manhole cover or outlet valve cap is removed form a 
tank car, the car must be relieved of all interior pressure by cooling 
the tank with water or by venting the tank by raising the safety valve 
or opening the dome vent at short intervals. However, if venting to 
relieve pressure will cause a dangerous amount of vapor to collect 
outside the car, venting and unloading must be deferred until the 
pressure is reduced by allowing the car to stand overnight or otherwise 
cooling the contents. These precautions are not necessary when the car 
is equipped with a manhole cover which hinges inward or with an inner 
manhole cover which does not have to be removed to unload the car, and 
when pressure is relieved by piping vapor into a condenser or storage 
tank.

    (1) Prior to modification of any UN portable tank which may affect 
conformance and the safe use of the portable tank, which may involve a 
change to the design type or which may affect its ability to retain 
hazardous material in transportation, the person desiring to make such 
modification shall inform the approval agency that issued the initial 
approval of the portable tank (or if unavailable, another approval 
agency) of the nature of the modification and request approval of the 
modification. The person desiring to modify the tank must supply the 
approval agency with three sets of all revised drawings, calculations, 
and test

    (3) Cargo tanks used in dedicated service for materials classed as 
corrosive material, with no secondary hazard, may have a total venting 
capacity which is less than required by Sec.  178.345-10(e). The 
minimum total venting capacity for these cargo tanks must be determined 
in accordance with the following formula (use of approximate values 
given for the formula is acceptable):

Formula in Nonmetric Units

Q = 37,980,000 A0.82 (ZT)0.5 / 
(LC)(M0.5)

Where:

Q = The total required venting capacity, in cubic meters of air per 
hour at standard conditions of 15.6 [deg]C and 1 atm (cubic feet of 
air per hour at standard conditions of 60 [deg]F and 14.7 psia);
T = The absolute temperature of the vapor at the venting 
conditions--degrees Kelvin ([deg]C+273) [degrees Rankine 
([deg]F+460)];
A = The exposed surface area of tank shell--square meters (square 
feet);
L = The latent heat of vaporization of the lading--calories per gram 
(BTU/lb);
Z = The compressibility factor for the vapor (if this factor is 
unknown, let Z equal 1.0);
M = The molecular weight of vapor;
C = A constant derived from (K), the ratio of specific heats of the 
vapor. If (K) is unknown, let C = 315.

C = 520[K(2/(K+1))[(K+1)/(K-1)]]0.5

Where:

K = Cp / Cv
Cp = The specific heat at constant pressure, in -calories 
per gram degree centigrade (BTU/lb [deg]F.); and
Cv = The specific heat at constant volume, in -calories 
per gram degree centigrade (BTU/lb [deg]F.).

    (ii) The packaging may be tested using a dynamic compression 
testing machine. The test must be conducted at room temperature on an 
empty, unsealed packaging. The test sample must be centered on the 
bottom platen of the testing machine. The top platen must be lowered 
until it comes in contact with the test sample. Compression must be 
applied end to end. The speed of the compression tester must be one-
half inch plus or minus one-fourth inch per minute. An initial preload 
of 50 pounds must be applied to ensure a definite contact between the 
test sample and the platens. The distance between the platens at this 
time must be recorded as zero deformation. The force A to then be 
applied must be calculated using the formula:

Liquids: A = (n-1) [w + (s x v x 8.3 x .98)] x 1.5;
Solids: A = (n-1) (m x 2.2 x 1.5)

Where:

A = applied load in pounds
m = the certified maximum gross mass for the container in kilograms.
n = minimum number of containers that, when stacked, reach a height 
of 3 meters.
s = specific gravity of lading.
w = maximum weight of one empty container in pounds.
v = actual capacity of container (rated capacity + outage) in 
gallons.

And:

8.3 corresponds to the weight in pounds of 1.0 gallon of water.
.98 corresponds to the minimum filling percentage of the maximum 
capacity for liquids.
1.5 is a compensation factor that converts the static load of the 
stacking test into a load suitable for dynamic compression testing.
2.2 is the conversion factor for kilograms to pounds.
