Sec. 241.7  Tolerances to be allowed.

    (a) The tolerances to be allowed in excess or in deficiency on the 
dimensions of all barrels of Class 1 shall be as follows:

------------------------------------------------------------------------
                                                               Tolerance
                                                                inches
------------------------------------------------------------------------
Diameter of head............................................       \1/4\
Effective diameter of head..................................       \1/4\
Distance between heads......................................       \1/4\
Circumference of bulge, outside measurement.................      1\1/2\
Length of stave.............................................       \1/2\
------------------------------------------------------------------------

    (1) If no dimension of a barrel of Class 1 is in error by more than 
the tolerance given above, then the barrel is within the tolerance 
allowed.
    (2) If one or more of the dimensions of a barrel of Class 1 is in 
error by more than the tolerance given above, then the barrel is not 
within the tolerance allowed.
    (b) The tolerance to be allowed in excess or in deficiency on all 
barrels of Class 2 shall be 1\1/2\ inches (1.5) inches, and this 
tolerance is to be applied to the result obtained by the application of 
the following rule:
    (1) Having determined the errors of each dimension and given to each 
its proper sign (see Sec. 241.4), add the errors on the effective 
diameter of head and the distance between heads algebraically and 
multiply the result by 1.67 (or \5/3\). Then add this result to the 
error on the circumference of bulge algebraically. If the result 
obtained is not greater than the tolerance given above, then the barrel 
is within the tolerance allowed; if the result is greater than this 
tolerance, then the barrel is not within the tolerance allowed.

    Note: To find the algebraic sum of a number of quantities having 
different signs, first add all those having one sign; then add all those 
having the opposite sign; then subtract the smaller sum from the larger, 
giving this result the sign of the larger quantity.

    (2) [Reserved]
    (c) The tolerance to be allowed in excess or in deficiency on the 
dimensions of all barrels for cranberries shall be as follows:

------------------------------------------------------------------------
                                                              Tolerance,
                                                                inches
------------------------------------------------------------------------
Diameter of head............................................       \1/4\
Effective diameter of head..................................       \1/4\
Distance between heads......................................       \1/4\
Circumference of bulge, outside measurement.................      1\3/8\
Length of stave.............................................       \1/2\
------------------------------------------------------------------------

    (1) If no dimension of a barrel for cranberries is in error by more 
than the tolerance given above, then the barrel is within the tolerance 
allowed.
    (2) If one or more of the dimensions of a barrel for cranberries is 
in error by more than the tolerance given above, then the barrel is not 
within the tolerance allowed.
    (d) The tolerances to be allowed in excess or in deficiency on all 
subdivisions of the standard barrel for fruits, vegetables, and other 
dry commodities other than cranberries, and on all subdivisions of the 
standard barrel for cranberries, shall be the values given in the 
following table, and these tolerances are to be applied to the result 
obtained by the application of the following rule:
    (1) Having determined the errors on each dimension and given to each 
its proper sign (see Sec. 241.5), add the errors on the effective 
diameter of head and the distance between heads algebraically and 
multiply the result by 1.67 (or \5/3\). Then add this result to the 
error on the circumference of bulge algebraically. If the result 
obtained is not greater than the tolerance given in the following table 
for the proper subdivision, then the barrel is within the tolerance 
allowed; if the result is greater than this tolerance, then the barrel 
is not within the tolerance allowed.
