4 Methods of quantity determination
4.1 Destructive and non-destructive testing
For economic and practical reasons destructive testing should be used only when non-destructive
testing is impractical.
4.2 Determination of quantity of product in solid form when declared by mass
4.2.1 Apparatus
Weighing instrument, shall be of a suitable type and sufficiently accurate to determine the gross
quantity of the package and mass of the container used so that a net quantity of the contents can be
determined.
“Suitable type” means a non-automatic weighing instrument that complies with the requirements of
EN 45501:2015.
“Sufficiently accurate” means that the scale intervals or sensitivity of the non-automatic weighing
instrument shall be no more than one fifth of the tolerable error permitted by the Regulation (EU)
2019/1009 [4] in relation to the nominal quantity being weighed.
Since half a graduation can be read on an analogue indicator non-automatic weighing instrument mass
display, digital display instruments will need to indicate 50 % of the minimum required for an analogue
indicator instrument.
4.2.2 Equipment check
Before using the non-automatic weighing instrument to establish the quantity, it shall be checked with
weights which comply with OIML R111-1 and have a measurement error of no more than one third of
the maximum error for the non-automatic weighing instrument under test. The tests shall be performed
according to EN 45501:2015.
A record should be kept of the results of the tests.
4.2.3 Determination methods
4.2.3.1 Packages up to 25 kg
The net quantity of material in any individual package is obtained by the difference between the gross
quantity and the mass of an empty container.
Place each package under test on the weighing plate of the non-automatic weighing instrument and
record the gross quantity (x).
Determine the mass of each of 10 randomly selected empty containers, record the masses and obtain a
mean mass of the containers (y). Record the calculation and result (non-destructive testing).
If empty containers are not available, empty and weigh 10 containers randomly selected from those
already weighed gross after ensuring no product remains in or on the containers. Obtain a mean mass
for the containers as above (y) (destructive testing).
If less than 10 packages are being tested, and empty containers are not available, destructive testing
should be carried out on all packages under test.
Subtract the mean mass of the containers from the gross quantity of each packed product and calculate
and record each net quantity (z) using Formula (1).
z xy− (1)
where
z is the net quantity by mass of the contents of an individual package in g;
x is the gross quantity by mass of an individual package in g;
y is the mean mass of the empty containers in g.
4.2.3.2 Packages more than 25 kg
These are packages which cannot be manually handled and require larger capacity non-automatic
weighing instruments to ascertain their gross mass.
The non-automatic weighing instrument used shall be of a suitable type and sufficiently accurate for the
net quantity in the package (see 4.2.1).
The procedure detailed in 4.2.3.1 shall be followed except that the number of empty containers to be
weighed may be reduced to 5 or all under test if less than 5.
4.2.3.3 Product sold in bulk
4.2.3.3.1 Product to be delivered in transport containers
This product will need to be loaded into some type of transport container (vehicle, large container or
other suitable method of containing the product). Use a non-automatic weighing instrument suitable for
the quantity of product in the container/consignment (see 4.2.1). The transport container shall be
weighed empty and the mass (m ) recorded. The product shall then be placed in the transport container
t
and the gross quantity (m ) recorded. Calculate the net quantity (m ) of the product using Formula (2).
g n
m mm− (2)
n gt
where
m is the net quantity of the product in kg;
n
m is the gross quantity of the product and transport container in kg;
g
m is the mass of the transport container empty in kg.
t
NOTE It is equally acceptable to weigh the gross quantity first and then empty the transport container and
determine the mass empty.
4.2.3.3.2 Product to be delivered in large quantities
One of the following methods shall be used.

4 Methods of quantity determination
4.1 Destructive and non-destructive testing
For economic and practical reasons destructive testing should be used only when non-destructive
testing is impractical.
4.2 Determination of quantity of product in solid form when declared by mass
4.2.1 Apparatus
Weighing instrument, shall be of a suitable type and sufficiently accurate to determine the gross
quantity of the package and mass of the container used so that a net quantity of the contents can be
determined.
“Suitable type” means a non-automatic weighing instrument that complies with the requirements of
EN 45501:2015.
“Sufficiently accurate” means that the scale intervals or sensitivity of the non-automatic weighing
instrument shall be no more than one fifth of the tolerable error permitted by the Regulation (EU)
2019/1009 [4] in relation to the nominal quantity being weighed.
Since half a graduation can be read on an analogue indicator non-automatic weighing instrument mass
display, digital display instruments will need to indicate 50 % of the minimum required for an analogue
indicator instrument.
4.2.2 Equipment check
Before using the non-automatic weighing instrument to establish the quantity, it shall be checked with
weights which comply with OIML R111-1 and have a measurement error of no more than one third of
the maximum error for the non-automatic weighing instrument under test. The tests shall be performed
according to EN 45501:2015.
A record should be kept of the results of the tests.
4.2.3 Determination methods
4.2.3.1 Packages up to 25 kg
The net quantity of material in any individual package is obtained by the difference between the gross
quantity and the mass of an empty container.
Place each package under test on the weighing plate of the non-automatic weighing instrument and
record the gross quantity (x).
Determine the mass of each of 10 randomly selected empty containers, record the masses and obtain a
mean mass of the containers (y). Record the calculation and result (non-destructive testing).
If empty containers are not available, empty and weigh 10 containers randomly selected from those
already weighed gross after ensuring no product remains in or on the containers. Obtain a mean mass
for the containers as above (y) (destructive testing).
If less than 10 packages are being tested, and empty containers are not available, destructive testing
should be carried out on all packages under test.
Subtract the mean mass of the containers from the gross quantity of each packed product and calculate
and record each net quantity (z) using Formula (1).
z xy− (1)
where
z is the net quantity by mass of the contents of an individual package in g;
x is the gross quantity by mass of an individual package in g;
y is the mean mass of the empty containers in g.
4.2.3.2 Packages more than 25 kg
These are packages which cannot be manually handled and require larger capacity non-automatic
weighing instruments to ascertain their gross mass.
The non-automatic weighing instrument used shall be of a suitable type and sufficiently accurate for the
net quantity in the package (see 4.2.1).
The procedure detailed in 4.2.3.1 shall be followed except that the number of empty containers to be
weighed may be reduced to 5 or all under test if less than 5.
4.2.3.3 Product sold in bulk
4.2.3.3.1 Product to be delivered in transport containers
This product will need to be loaded into some type of transport container (vehicle, large container or
other suitable method of containing the product). Use a non-automatic weighing instrument suitable for
the quantity of product in the container/consignment (see 4.2.1). The transport container shall be
weighed empty and the mass (m ) recorded. The product shall then be placed in the transport container
t
and the gross quantity (m ) recorded. Calculate the net quantity (m ) of the product using Formula (2).
g n
m mm− (2)
n gt
where
m is the net quantity of the product in kg;
n
m is the gross quantity of the product and transport container in kg;
g
m is the mass of the transport container empty in kg.
t
NOTE It is equally acceptable to weigh the gross quantity first and then empty the transport container and
determine the mass empty.
4.2.3.3.2 Product to be delivered in large quantities
One of the following methods shall be used.
