    37-603.  STANDARD BABCOCK TESTING GLASSWARE. The term "Standard Babcock
testing glassware" shall apply to glassware complying with the following
specifications:
    a.  Standard Milk Test Bottles.
    Graduation for Milk Test Bottles. The total per cent graduation shall be
eight (8). The graduated portion of the neck shall have a length of no less
than sixty-three and five-tenths (63.5) millimeters (two and one-half inches
(2 1/2")), the graduations shall represent whole per cent, five-tenths per
cent (.5%), and tenths per cent (.1%). The tenths per cent (.1%) graduations
shall not be less than three (3) millimeters in length; the five-tenths per
cent (.5%) graduations shall be one (1) millimeter longer than the tenths per
cent (.1%), graduations projecting one (1) millimeter to the left; the whole
per cent graduation shall extend at least one-half (1/2) way around the neck
to the right and project two (2) millimeters to the left of the tenths per
cent (.1%) graduation. Each per cent graduation shall be numbered, the number
being placed on the left of the scale. The error at any point of the scale
shall not exceed one-tenth per cent (.1%).
    Neck. The neck shall be cylindrical and the cylindrical shape shall extend
for at least nine (9) millimeters below the lowest and above the highest
graduation mark. The top of the neck shall be flared to a diameter of not less
than ten (10) millimeters.
    Bulb. The capacity of the bulb up to the junction of the neck shall not be
less than forty-five (45) cubic centimeters. The shape of the bulb may be
either cylindrical or conical with the smallest diameter at the bottom. If
cylindrical, the outside diameter shall be between thirty-four (34) and
thirty-six (36) millimeters; if conical, the outside diameter of the base
shall be between thirty-one (31) and thirty-three (33) millimeters, and the
maximum diameter between thirty-five (35) and thirty-seven (37) millimeters.
The charge of the bottle shall be eighteen (18) grams. The total height of the
bottle shall be between one hundred (100) and one hundred sixty-five (165)
millimeters (five and seven-eighths (5 7/8") inches and six and one-half
inches (6 1/2")).
    b.  Standard Cream Test Bottles.
    Three (3) types of bottles shall be accepted as standard cream test
bottles, a fifty per cent (50%) nine (9)-gram short-neck bottle, a fifty per
cent (50%) nine-gram long-neck bottle, and a fifty per cent (50%) eighteen
(18)-gram long-neck bottle.
    Fifty Per Cent (50%) Nine (9)-gram Short-neck Bottle-Graduation. The total
per cent graduation shall be fifty (50). The graduated portion of the neck
shall have a length of not less than sixty-three and five-tenths (63.5)
millimeters (two and one-half inches (2 1/2")). The graduation shall represent
five per cent (5%), one per cent (1%) and five-tenths per cent (.5%). The five
per cent (5%) graduation shall extend at least half-way around the neck to the
right.
    The five-tenths per cent (.5%) graduations shall be at least three (3)
millimeters in length, and one per cent (1%) graduations shall have a length
intermediate between the five per cent (5%) and five-tenths per cent (.5%)
graduations. Each five per cent (5%) graduation shall be numbered, the number
being placed on the left of the scale. The error at any point of the scale
shall not exceed five-tenths (.5%) per cent.
    Neck. The neck shall be cylindrical and the cylindrical shape shall extend
at least nine (9) millimeters below the lowest and nine (9) millimeters above
the highest graduation mark. The top of the neck shall be flared to a diameter
of not less than ten (10) millimeters.
    Bulb. The capacity of the bulb up to the junction of the neck shall not be
less than forty-five (45) cubic centimeters. The shape of the bulb may be
either cylindrical or conical with the smallest diameter at the bottom. If
cylindrical, the outside diameter shall be between thirty-four (34) and
thirty-six (36) millimeters. If conical, the outside diameter of the base
shall be between thirty-one (31) and thirty-three (33) millimeters and the
maximum diameter between thirty-five (35) and thirty-seven (37) millimeters.
    The charge of the bottle shall be nine (9) grams.
    All bottles shall bear on the top of the neck above the graduations in
plainly legible characters, a mark, defining the weight of the charge to be
used (nine (9) grams).
    The total height of the bottle shall be between one hundred fifty (150)
and one hundred sixty-five (165) millimeters (five and seven-eighths inches (5
7/8") and six and one-half inches (6 1/2")), same as standard milk test
bottles.
    Fifty Per Cent (50%), Nine (9)-gram, Long-neck Bottle. The same
specifications in every detail as specified for the fifty per cent (50%) nine
(9)-gram, short-neck bottle shall apply for the long-neck bottle, with the
exception, however, that the total height of this bottle shall be between two
hundred ten (210) and two hundred thirty-four (234) millimeters (eight and
one-fourth inches (8 1/4") and eight and seven-eighths inches (8 7/8")) and
that the total length of the graduation shall be not less than one hundred
twenty (120) millimeters.
    Fifty Per Cent (50%), Eighteen (18)-gram, Long-neck Bottle. The same
specifications in every detail as specified for the fifty per cent (50%) nine
(9)-gram, long-neck bottle shall apply, with the exception that the charge of
the bottle shall be eighteen (18) grams, and the mark defining the weight of
the charge placed at the top of the neck shall be eighteen (18).
    The total length of the standard Babcock pipette shall be not more than
three hundred thirty (330) millimeters (thirteen and one-fourth inches (13
1/4")). Outside diameter of suction tube six (6) to eight (8) millimeters.
Length of suction tube one hundred thirty (130) millimeters. Outside diameter
of delivery tube four and five-tenths (4.5) to five and five-tenths (5.5)
millimeters. The length of delivery tube one hundred (100) to one hundred
twenty (120) millimeters. Distance of graduation mark above bulb thirty (30)
to sixty (60) millimeters. Nozzle straight. Delivery seventeen and six-tenths
(17.6) cubic centimeters of water at twenty (20) degrees Centigrade in five
(5) to eight (8) seconds.
