(2) Weigh the 15-dozen-egg sample in cartons, on a scale, to the nearest
1/4 pound. For review of the task, see Subcourse MD0704, Inspection Records and
Reports. Do not weigh cartons one at a time. This may introduce too much error,
especially when using case-weighing scales. If a carton has one or more eggs missing
from the carton, do not replace the missing eggs.
(3) Determine the tare weight of the half-cases. To review how this is done,
see Subcourse MD0704, Lesson 3. If the tare weight must be established, you must
weigh no less than 15 empty cartons.
(4) Subtract the tare weight from the gross weight to obtain the net weight of
the sample (half-case).
(5) Multiply the net weight of the sample (half-case) by two in order to obtain
the actual net weight of the case (figure 2-11).
Figure 2-11. Determining net weight of a case of eggs.
(6) Record the net weight on the reverse side of DD Form 1237 (see
Lesson 4 of this subcourse) or other locally approved form as appropriate.
c. Determine Actual Net Weight of Wholesale Grade Shell Eggs. Net weight
may be obtained by one of two methods, by weighing a half-case or a whole-case
sample. The half-case sample is more commonly used.
