                     Subpart A--Scope of Regulations
 
Sec. 30.1  Gauging of distilled spirits.


    (a) General. This part relates to the gauging of distilled spirits. 
The term ``gauging'' means the determination of the proof and the 
quantity of distilled spirits. The procedures prescribed in or 
authorized under the provisions of this part, except as may be otherwise 
authorized in this chapter, shall be followed in making any 
determination of quantity or proof of distilled spirits required by or 
under the authority of regulations in this chapter. The tables referred 
to in subpart E of this part appear in the ``Gauging Manual Embracing 
Instructions and Tables for Determining Quantity of Distilled Spirits by 
Proof and Weight'' as incorporated by reference in this part (see 
paragraph (c) of this section). These tables, together with their 
instructions, shall be used, wherever applicable, in making the 
necessary computations from gauge data.
    (b) Tables referred to in subpart E of this part. Table 1 provides a 
method of correcting hydrometer indications at temperatures between 0 
and 100 degrees Fahrenheit to true proof. If distilled spirits contain 
dissolved solids, temperature correction of the hydrometer reading by 
the use of this table would result in apparent proof rather than true 
proof. Tables 2 and 3 show the gallonage of spirituous liquor according 
to weight and proof. Table 4 shows the gallons per pound at each one-
tenth proof from 1 to 200 proof. Table 5 shows the weight per wine 
gallon and proof gallon at each proof. Table 6 shows the volumes of 
alcohol and water and the specific gravity (air and vacuum) of 
spirituous liquor at each proof. Table 7 provides a means of 
ascertaining the volume (at 60 degree Fahrenheit) of spirits at various 
temperatures ranging from 18 degrees through 100 degrees Fahrenheit.
    (c) Incorporation by reference. The ``Gauging Manual Embracing 
Instructions and Tables for Determining Quantity of Distilled Spirits by 
Proof and Weight'' (ATF Publication 5110.6; November 1978) is 
incorporated by reference in this part. This incorporation by reference 
was approved by the Director of the Federal Register on March 23, 1981.
