(1) Whole-case sample. You may determine the net weight of eggs packed

in uniform (one-type-construction) fiber cases by removing all eggs from at least two

cases and obtaining the average tare (case and packing materials) per case. Then

weigh each sample case and obtain the net weight by subtracting the average tare from

the gross weight. An average tare may not be used for wood cases.

(2)

Half-case sample. You will be weighing one compartment of eggs.

(a) Remove half-case sample from the container (all fillers, flats, and

eggs) (figure 2-12).

Figure 2-12. Six layers of eggs.

(b) Weigh the half-case on the scale to the nearest 1/4 pound (fig.

2-13). If a layer has one or more eggs missing from the tray, the missing eggs are not

replaced.

(c) Multiply the gross weight of the sample (half-case by two) in order

to obtain the total gross weight of the cases.

(d) Determine the tare weight of the half-case. If domestic shipment,

use standard tare (3 1/2 pounds, if fillers and flats, or 2 pounds if filler-flats). If the

inspector has 20 or more sets of fillers and flats available for weighing, he may

determine a tare for the lot, rather than using the standard tare (figure 2-14).

(e) Subtract the tare weight from the gross weight to obtain the net

weight of the sample (half-case).

(f) Record the net weight on the reverse side of DD Form 1237 (see

Lesson 4) or other locally approved form as appropriate (figure. 2-15).
