                        TITLE 49--TRANSPORTATION
 
 CHAPTER I--RESEARCH AND SPECIAL PROGRAMS ADMINISTRATION, DEPARTMENT OF 
                             TRANSPORTATION
 
PART 173--SHIPPERS--GENERAL REQUIREMENTS FOR SHIPMENTS AND PACKAGINGS--Table of Contents
 
               Subpart I--Class 7 (Radioactive) Materials
 
Sec. 173.461  Demonstration of compliance with tests.

    (a) Compliance with the design requirements in Sec. 173.412 and the 
test requirements in Secs. 173.465 through 173.469 must be shown by any 
of the methods prescribed in this paragraph, or by a combination of 
these methods appropriate for the particular feature being evaluated:
    (1) Performance of tests with prototypes or samples of the specimens 
representing LSA-III, special form Class 7 (radioactive) material, or 
packaging, in which case the contents of the packaging for the test must 
simulate as closely as practicable the expected range of physical 
properties of the radioactive contents or packaging to be tested, must 
be prepared as normally presented for transport. The use of non-
radioactive substitute contents is encouraged provided that the results 
of the testing take into account the radioactive characteristics of the 
contents for which the package is being tested;
    (2) Reference to a previous, satisfactory demonstration of 
compliance of a sufficiently similar nature;
    (3) Performance of tests with models of appropriate scale 
incorporating those features that are significant with respect to the 
item under investigation, when engineering experience has shown results 
of those tests to be suitable for design purposes. When a scale model is 
used, the need for adjusting certain test parameters, such as the 
penetrator diameter or the compressive load, must be taken into account; 
or
    (4) Calculations or reasoned evaluation, using reliable and 
conservative procedures and parameters.
    (b) With respect to the initial conditions for the tests under 
Secs. 173.465 through 173.469, except for the water immersion tests, 
compliance must be based upon the assumption that the package is in 
equilibrium at an ambient temperature of 38  deg.C (100  deg.F).
