Sec. 4.41. Liquid Measures

# A. Application

**A.1.** - This code applies to liquid measures; that is, to rigid
measures of capacity designed for general and repeated use in the
measurement of liquids.

**A.2.** - The code does not apply to test measures or other volumetric
standards.

**A.3.** - See also Sec. 1.10; General Code requirements.

# S. Specifications

**S.1. Units.** -

> a\. The capacity of a liquid measure shall be 0.1 L, 0.2 L, 0.5 L,
> 1 L, 2 L, 5 L, or a multiple of 5 L, and the measure shall not be
> subdivided.
>
> b\. The capacity of a liquid measure shall be 1 gill, 1/2 liquid pint,
> 1 liquid pint, 1 liquid quart, 1/2 gallon, 1-1/4 gallon, 1-1/2 gallon,
> or a multiple of 1 gallon, and the measure shall not be subdivided.
> However, 3-pint and 5-pint brick molds and 2-1/2 gallon (10-quart)
> cans shall be permitted when used exclusively for ice cream.

**S.2. Material.** - Measures shall be made of metal, glass,
earthen­ware, enameled ware, composition, or similar and suitable
material. If made of metal, the thickness of the metal shall not be less
than the appropriate value given in Table 1.

**S.3. Capacity Point.** - The capacity of a measure shall be deter­mined
to a definite edge, or to the lowest portion of a plate, bar, or wire,
at or near the top of the measure, and shall not include the capacity of
any lip or rim that may be provided.

**S.4. Reinforcing Rings.** - Reinforcing rings, if used, shall be
attached to the outside of the measure and shall show no divisions or
lines on the inside surface of the measure.

**S.5. Discharge.** - A measure equipped with a discharge faucet or
valve shall be susceptible to complete discharge through the faucet or
valve when the measure is standing on a level surface.

**S.6. Marking Requirements.** - A measure shall be marked on its side
with a statement of its capacity. If the capacity is stated in terms of
the pint or quart, the word \"Liquid\" or the abbreviation \"Liq\" shall
be included.

# T. Tolerances

**T.1.** - Maintenance tolerances in excess and in deficiency shall be
as shown in Table 2. Acceptance tolerances shall be one-half the
maintenance tolerances.
