- Method for the inspection of imperfect kernel
1 Scope
This part of SN/T 0800 specifies the inspection methods for imperfect kernel of
cereals, oil bearing materials and feedstuffs for import and export.
This section applies to the inspection of imperfect kernel of cereals, oil bearing
materials and feedstuffs for import and export.

3 Terms and definitions
The terms and definitions defined by SN/T 0798 apply to this document.
4 Sampling and sample preparation
See SN/T 0800.1 for sampling and sample preparation methods.
5 Inspection
5.1 Instruments and utensils
5.1.1 Electronic balance: Sensitivity 0.1 g and 0.01 g.
5.1.2 Sample tray.
5.1.3 Small dishes.
5.1.4 Hand-held magnifying lens.
5.1.5 Tweezers.
5.1.6 Scalpel.
5.2 Inspection method
5.2.1 Cereal and feedstuff
(when necessary, large and medium grain samples shall be cut or peeled off
for identification). Then place them in a small dish; weigh them on a balance
which has a sensitivity of 0.01 g. Record the weighing results.
5.2.1.2.2 Result calculation
The percentage of total imperfect kernels of other cereals and feedstuffs is
calculated according to formula (2).
Where:
b' - Percentage of total amount of imperfect kernels, %;
t1 - The percentage of large impurity content, %;
t2 - The percentage of harmful and toxic impurities, %;
m'n - The mass of each sub-item of the imperfect kernel, in grams (g);
m1 - The mass of the imperfect kernel specimen, in grams (g).
For the inspection result of the total amount of imperfect kernels, it takes one
decimal place. For the inspection result of the sub-item of imperfect kernels,
it takes two decimal places.
The attribution of the shared items of the sub-item of imperfect kernels is
based on the attribution rules of the sub-item shared item in SN/T 0799.
5.2.2 Oil bearing materials
5.2.2.1 Inspection steps
Prepare specimens according to the sample preparation method specified in
SN/T 0800.1. Calculate the percentage of impurity content in large-sized
samples (t3) according to the method in SN/T 0803.6. The amount of imperfect
kernels is determined in accordance with Appendix A. In accordance with
Appendix B and SN/T 0798, combined with the definitions in GB 1352, GB/T
11761, GB/T 11762, select various imperfect kernels that have been identified
by naked eyes or with a magnifying lens (the large and medium grain samples
shall be cut or stripped for identification if necessary). Then place them in a
small dish. Weigh them on a balance which has a sensitivity of 0.01 g. Record
the weighing results.
