    For the purposes of this part:
    (a) The procedure for determining drained weight is set forth in the 
``Official Methods of Analysis of the Association of Official Analytical 
Chemists,'' 13th Ed. (1980), sections 32.001-32.003, which is 
incorporated by reference. Copies are available from the Association of 
Official Analytical Chemists International, 481 North Frederick Ave,

    (b) Compliance means the following: Unless otherwise provided in a 
standard, a lot of canned vegetables shall be deemed in compliance for 
the following factors, to be determined by the sampling and acceptance 
procedure as provided in paragraph (c) of this section, namely:
    (1) Quality. The quality of a lot shall be considered acceptable 
when the number of defectives does not exceed the acceptance number (c) 
in the sampling plans.
    (2) Fill of container. A lot shall be deemed to be in compliance for 
fill of container (packing medium and vegetable ingredient) when the 
number of defectives does not exceed the acceptance number (c) in the 
sampling plans.
    (3) Drained weight. A lot shall be deemed to be in compliance for 
drained weight based on the average value of all samples analyzed 
according to the sampling plans.
    (c) The sampling and acceptance procedure means the following:
    (1) Definitions--(i) Lot. A collection of primary containers or 
units of the same size, type, and style manufactured or packed under 
similar conditions and handled as a single unit of trade.
    (ii) Lot size. The number of primary containers or units in the lot.
    (iii) Sample size. The total number of sample units drawn for 
examination from a lot.
    (iv) Sample unit. A container, a portion of the contents of a 
container, or a composite mixture of product from small containers that 
is sufficient for the examination or testing as a single unit. For fill 
of container, the sample unit shall be the entire contents of the 
container.
    (v) Defective. Any sample unit shall be regarded as defective when 
the sample unit does not meet the criteria set forth in the standards.
    (vi) Acceptance number (c). The maximum number of defective sample 
units permitted in the sample in order to consider the lot as meeting 
the specified requirements.
    (vii) Acceptable quality level (AQL). The maximum percent of 
defective sample units permitted in a lot that will be accepted 
approximately 95 percent of the time.
    (2) Sampling plans.

\1\ n = number of primary containers in sample.

    (d) Strength and redness of color means at least as much red as is 
obtained by comparison of the prepared product, with the blended color 
produced by spinning a combination of the following concentric Munsell 
color discs of equal diameter, or the color equivalent of such discs:

Disc 1--Red (5R 2.6/13) (glossy finish)
Disc 2--Yellow (2.5 YR 5/12) (glossy finish)
Disc 3--Black (N1) (glossy finish)
Disc 4--Grey (N4) (mat finish)


Such comparison is to be made in full diffused daylight or under a 
diffused light source of approximately 2691 lux (250 footcandles) and 
having a spectral quality approximating that of daylight under a 
moderately overcast sky, with a correlated color temperature of 7,500 
degrees Kelvin plus-minus200 degrees. With the light source 
directly over the disc and product, observation is made at an angle of 
45 degrees from a distance of about 24 inches from the product. 
Electronic color meters may be used as an alternate means of determining 
the

[[Page 462]]

color of tomato concentrates. Such meters shall be calibrated to 
indicate that the color of the product is as red or more red than that 
produced by spinning the Munsell color discs in the combination as set 
out above.
    (e) Tomato soluble solids means the sucrose value as determined by 
the method prescribed in the ``Official Methods of Analysis of the 
Association of Official Analytical Chemists,'' 13th Ed., 1980, sections 
32.014 to 32.016 and 52.012, under the headings ``Soluble Solids in 
Tomato Products Official Final Action'' and ``Refractive Indices (n) of 
Sucrose Solutions at 20 deg.,'' which is incorporated by reference. 
Copies are available from the Association of Official Analytical 
Chemists International, 481 North Frederick Ave., suite 500, 
Gaithersburg, MD 20877-2504, or are available for inspection at the 
Office of the Federal Register, 800 North Capitol Street, NW., suite 
700, Washington, DC. If no salt has been added, the sucrose value 
obtained from the referenced tables shall be considered the percent of 
tomato soluble solids. If salt has been added either intentionally or 
through the application of the acidified break, determine the percent of 
such added sodium chloride as specified in paragraph (f) of this 
section. Subtract the percentage so found from the percentage of total 
soluble solids found (sucrose value from the refractive index tables) 
and multiply the difference by 1.016. The resultant value is considered 
the percent of ``tomato soluble solids.''
    (f) Salt means sodium chloride, determined as chloride and 
calculated as percent sodium chloride, by the method prescribed in 
``Official Methods of Analysis of the Association of Official Analytical 
Chemists,'' 13th Ed., 1980, sections 32.025 to 32.030, under the heading 
``Method III (Potentiometric Method),'' which is incorporated by 
reference.
