Minimum thickness of artificial barricades' (in.) 'When the ammonium nitrate and/or blasting agent is not barricaded, the distances shown in the Table shall be multiplied by six. These distances allow for the possibility of high velocity metal fragments from mixers, hoppers, truck bodies, sheet metal structures, metal containers, and the like which may enclose the "donor." Where storage is in bullet-resistant magazines recommended for explosives or where the storage is protected by a bullet-resistant wall, distances and barricade thicknesses in excess of those prescribed in the American Table of Distances are not required. *The distances in the Table apply to ammonium nitrate that passes the insensitivity test prescribed in the definition of ammonium nitrate fertilizer promulgated by the National Plant Food Institute; and ammonium nitrate failing to pass said test shall be stored at separation distances determined by competent persons and approved by the authority having jurisdiction. 'These distances apply to nitro-carbo-nitrates and blasting agents which pass the insensitivity test prescribed in the U.S. Department of Transportation (DOT) regulations. 'Earth, or sand dikes, or enclosures filled with the prescribed minimum thickness of earth or sand are acceptable artificial barricades. Natural barricades, such as hills or timber of sufficient density that the surrounding exposures which require protection cannot be seen from the "donor" when the trees are bare of leaves are also acceptable. NOTE: Recommended separation distances to prevent explosion of ammonium nitrate and ammonium nitrate-based blasting agents by propagation from nearby stores of high explosives or blasting agents referred to in the Table as the "donor." Ammonium nitrate, by itself, is not considered to be a donor when applying this Table. Ammonium nitrate, ammonium nitrate-fuel oil or combinations thereof are acceptors. If stores of ammonium nitrate are located within the sympathetic detonation distance of explosives or blasting agents, one-half 30 the mass of the ammonium nitrate should be included in the mass of the donor. 100 100 300 300 600 600 1,000 1,000 1,600 1,600 2,000 2,000 3,000 3,000 4,000 4,000 6,000 6,000 8,000 These distances apply to the separation of stores only.

Subpart A-Scope of Regulations § 186.1 Gauging of distilled spirits. This part, the "Gauging Manual", relates to the gauging of distilled spirits. By "gauging" is meant the determination of the proof and the quantity of distilled spirits. Tables 1-7, together with their instructions, are provided as a part hereof and should be used, wherever applicable, in making the necessary computations from gauge data. Table 1 provides a method for 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, and Table 7 provides a means of ascertaining the volume (at 60 degrees Fahrenheit) of spirits at various temperatures ranging from 18 degrees through 100 degrees Fahrenheit. The procedures prescribed in, or authorized under the provisions of, this part shall, except as may be otherwise authorized in this chapter, be followed in making any de termination of quantity or proof of distilled spirits required by or under the authority of regulations in this chapter.

ATF-48, 43 FR 13541, Mar. 31, 1978] Subpart C-Gauging Instruments § 186.21 General requirements. ATF officers shall use only hydrometers and thermometers furnished by the Government: Provided, That where this part requires the use of a specific gravity hydrometer, ATF officers shall use precision grade specific gravity hydrometers conforming to the provisions of § 186.24a, furnished by the proprietor: Provided further, That the Director may authorize ATF officers to use (a) other instruments approved by the Director as being equally satisfactory for determination of specific gravity, or (b) as prescribed in § 186.25, other approved gauging instruments of unusual or costly design furnished by the proprietor. From time to time ATF officers shall verify the accuracy of hydrometers and thermometers used by proprietors. The proof of distilled spirits and rectified products shall be determined by the use of gauging instruments as prescribed in this part. (72 Stat. 1358; 26 U.S.C. 5204) [T.D. 7002, 34 FR 1590, Feb. 1, 1969. Redesignated at 40 FR 16835, Apr. 15, 1975] § 186.22 Hydrometers and thermometers. The hydrometers furnished to ATF officers are graduated to read the proof of aqueous alcoholic solutions at 60 degrees Fahrenheit; thus, they read, 0 for water, 100 for proof spirits, and 200 for absolute alcohol. Because of temperature-density relationships and the selection of 60 degrees Fahrenheit for reporting proof, the hydrometer readings will be less than the true percent of proof at temperatures below 60 degrees Fahrenheit and greater than the true percent of proof at temperatures above 60 degrees Fahrenheit. Hence, corrections are necessary for hydrometer readings at temperatures other than 60 degrees Fahrenheit. Precision hydrometers shall be used for gauging large quantities of spirits, such as bulk gauging for tax payment. Hydrometers and thermometers shall be used and the true percent of proof shall be determined in accordance with § 186.31. Hydrometers are designated by letter according to range of proof and are provided in ranges and subdivisions of stems as follows: § 186.23 Use of precision hydrometers and thermometers. Care should be exercised to obtain accurate hydrometer and thermometer readings. In order to accomplish this result, the following precautions should be observed. Bulk spirits should be thoroughly agitated so that the test sample will be representative of the entire quantity. The hydrometer should be kept clean and free of any oily substance. Immediately before readings are taken, the glass cylinder containing the thermometer should be rinsed several times with the spirits which are to be gauged so as to bring both the cylinder and the thermometer to the temperature of the spirits (if time permits, it is desirable to bring both the spirits and the instruments to room temperature). If the outer surface of the cylinder becomes wet, it should be wiped dry to avoid the cooling effect of rapid evaporation. During the readings the cylinder should be protected from drafts or other conditions which might affect its temperature or that of the spirits which it contains. The hands should not be placed on the cylinder in such a manner as to warm the liquid contained therein. The hydrometer should be inserted in the liquid and the hydrometer bulb raised and lowered from top to bottom 5 or 6 times to obtain an even temperature distribution over its surface, and, while the hydrometer bulb remains in the liquid, the stem should be dried and the hydrometer allowed to come to rest with |
