PART 241--BARRELS FOR FRUITS, VEGETABLES AND OTHER DRY COMMODITIES, AND FOR CRANBERRIES--Table of Contents
 
Sec. 241.4  Application of tolerance for ``diameter of head.''

    (a) The tolerance established in this part for the dimension 
specified as ``diameter of head'' shall be applied to the diameter of 
the head over all, including the part which fits into the croze ring of 
the completed barrel.
    (b) The tolerance established in this part for the dimension 
specified as ``effective diameter of head'' shall be applied as follows 
on the various types of barrels and subdivisions in use;

[[Page 374]]

    (1) When a barrel or subdivision thereof has two heads, the 
tolerance shall be applied to the mean of the average diameters from 
inside to inside of staves at the inner edges of the heads.
    (2) When a barrel or subdivision thereof has but one head and a 
croze ring or other means for the insertion of a head at the opposite 
end, the tolerance shall be applied to the mean of the average 
diameters, one taken from inside to inside of staves at the inner edge 
of the head, the other from inside to inside of staves at the inner edge 
of the croze ring, or from inside to inside of staves at a point where 
the inside surface of a head would come were such head inserted in the 
barrel.
    (3) When a barrel or subdivision thereof has but one head and no 
croze ring or other means for the insertion of a head at the opposite 
end, the tolerance shall be applied to the mean of the average 
diameters, one taken from inside to inside of staves at the inner edge 
of the head, the other taken from inside to inside of staves at a point 
1\1/8\ inches from the end of the staves in the case of a barrel or \3/
4\ barrel, or at a point 1 inch or \7/8\ inch from the end of the staves 
in the case of a \1/2\ barrel or \1/3\ barrel, respectively.
    (c) The standard allowance for depth of croze ring shall be \3/16\ 
inch. Therefore, the standard ``effective diameter of head'' in the case 
of the standard barrel is 16\3/4\ inches and in the case of the standard 
cranberry barrel is 15\7/8\ inches.
