Where.
m — Mass of a single nut, in units of grams (g);
m1 — Mass of sample nuts, in units of grams (g);
N — Number of sample nuts, in units of grain.
5.3 Kernel rate
In the samples, randomly WEIGH about 1000g of sample nuts. WEIGH the mass of
sample nuts. Then BREAK the nutshells and TAKE the kernels one by one. And
WEIGH the mass of kernels.
Kernel rate is calculated according to equation (2), accurate to the nearest integer.
Where.
X — Kernel rate, %;
m2 — Mass of sample kernels, in units of grams (g);
m1 — Mass of sample nuts, in units of grams (g).
5.4 Impurity content
Randomly WEIGH about 1000g of samples, and WEIGH the mass of samples. Then
PUT the samples on a clean table, PICK out the fruit buds, leaves, twigs, weeds, and
other impurities mixed in the nuts and weigh.
Impurity content is calculated according to equation (3), accurate to 0.1g.
Where.
I — Impurity content, %;
m3 — Mass of impurities in samples, in units of grams (g);
m4 — Mass of samples, in units of grams (g).
Where.
E — Empty nut rate, %;
N4 — Number of empty nuts, in units of grain;
N — Number of sample nuts, in units of grain.
5.8 Moisture
Determination method is shown in Annex A.
5.9 Hygienic inspection
Determination method is implemented according to the specifications of GB/T
5009.12, GB/T 5009.17, GB/T 5009.19, GB/T 5009.11, and GB/T 5009.20.
6 Test rules 
6.1 Batch
The hazelnuts of the same-origin, same-grade, and the same batch of acquisition,
transportation, and marketing are deemed as a test batch.
6.2 Sampling
IMPLEMENT according to the specifications of 2.1, 2.2.1.4, 2.3.2, and 3.1 of GB
5491-1985.
6.3 Determination rules
6.3.1 If the products meet the requirements of Chapter 4 after test, then this batch of
products are determined as qualified products of the corresponding grades according
to this Standard.
6.3.2 If there is one item not meeting the basic requirements of 4.1 and grade
requirements of 4.3, then this batch of products is determined as unqualified
according to this Standard.
6.3.3 In special-grade nuts, the mass of first-grade nuts and second-grade nuts shall
not exceed 12% of the total mass. In first-grade nuts, the mass of second-grade nuts
shall not exceed 12% of the total mass.
6.4 Re-inspection
Annex A 
(Normative)
Determination of moisture content - direct drying method
A.1 Principle
DETERMINE the moisture content by calculating the mass differences of hazelnut
nuts before and after being dried at 103°C (±2°C) in drying oven for 6h.
A.2 Appliances
A.1.1 Mortar.
A.2.2 Balance ( sensitivity is 0.001g).
A.2.3 Glass or metal weighing dishes with lids.
A.2.4 Electric drying oven with ventilation, and the temperature is adjusted to 103°C
(±2°C).
A.2.5 Dryers that contain effective desiccant (i.e., calcium chloride).
A.3 Sample preparation
BREAK the nutshells of the sample hazelnuts to be tested and TAKE out the kernels.
GRIND the kernels in a mortar. If necessary, PUT the hazelnut shells that are as
samples in a porcelain mortar to grind or crush to fine particles with the particle size of
2mm~4mm.
A.4 Drying processing, weighing, and calculation
A.4.1 DRY the weighing dish and its lid in the drying oven for at least 2h, then put
them in the dryer. COOL the weighing dish and its lid to room temperature.
A.4.2 WEIGH the mass (m0) of empty weighing dish and its lid.
A.4.3 WEIGH about 50g of the test materials, and SPREAD them evenly on the
bottom surface of the weighing dish that has been dried. Then COVER the weighing
dish with the lid quickly. WEIGH the whole mass (m1). When conducting this part of
the operation, OPERATE as quickly as possible.
A.4.4 PUT open weighing dish along with the lid into a drying oven. CLOSE ......
