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 solid or liquid fertilizing product when sold by mass

4.2.1 Apparatus

4.2.1.1 Weighing instrument, shall be of a suitable type and sufficiently accurate to determine the

gross quantity 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 [6] in relation to nominal quantity being weighed.

NOTE Since half a graduation can be read on an analogue indicator non-automatic weighing instrument

weight display, digital instruments will need to indicate 50 % of those required for an analogue graduation.

4.2.2 Equipment check

Before using the non-automatic weighing instrument to establish the quantity of a fertilizing product it

shall be checked with weights, which comply with OIML R111-1 [5] 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 are laid down in EN 45501:2015.
A record should be kept of the results of the tests.
4.2.3 Method
4.2.3.1 Packages 5 g to 25 kg

Place each package to be checked separately on the weighing plate of the non-automatic weighing

instrument and record the gross quantity for each (x).

Weigh 10 randomly selected empty containers (non-destructive testing) or if empty containers are not

available empty weigh 10 containers randomly selected from those already weighed, after ensuring no

fertilizing product remains in or on the containers (destructive testing).

Record the masses and obtain a mean mass of the containers (y). Record the calculation and result.

Subtract the mean mass of the container from the gross quantity of each packed fertilizing product and

calculate and record each net quantity (z) using Formula (1).
z x− y (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.

oSIST prEN 17817:2022
prEN 17817:2022 (E)
4.2.3.2 Packages more than 25 kg to 1 t

These are packages which cannot be manually handled and require larger capacity non-automatic

weighing instruments to ascertain their gross weight.

The non-automatic weighing instrument used shall be of a suitable type and sufficiently accurate for the

net quantity of fertilizing product in the package. See 4.2.1.1.

The procedure detailed in 4.2.3.1 shall be followed except that the number of empty containers to be

weighed should be reduced to 5.
4.2.3.3 Fertilizing product sold loose and in bulk

This fertilizing product will need to be loaded into some type of transport container (vehicle, large

container or other suitable method of containing the fertilizing product). Using a non-automatic

weighing instrument suitable for the quantity of fertilizing product in the container/consignment (see

4.2.1.1). The transport container shall be weighed empty and the mass (m ) recorded. The fertilizing

product shall then be placed in the transport container and the gross quantity (m ) recorded. The net

quantity (m ) of the fertilizing product can then be calculated using the Formula (2).

m mm− (2)
n g t
where
mn is the net quantity of the fertilizing product in kg;

m is the gross quantity of the fertilizing product and transport container in kg;

m is the mass of the transport container empty in kg.

NOTE It is equally acceptable to weigh the gross quantity first and then empty the transport container and

determine the mass empty.
4.3 Determination of quantity of liquid fertilizing product when sold by volume
4.3.1 Apparatus
4.3.1.1 Weighing instrument capable of weighing to the nearest 0,1 g.
4.3.1.2 Sampling equipment as per EN 1482-1:2007.
4.3.1.3 Density determination equipment,
a density bottle, or
a graduated measuring cylinder with maximum 2 ml graduations, or
a density meter reading to three decimal places.
4.3.1.4 Water bath at (20 ± 1) °C.
4.3.2 Equipment check
Check weighing equipment as detailed in 4.2.2.

oSIST prEN 17817:2022
prEN 17817:2022 (E)
4.3.3 Method
4.3.3.1 Determination of quantity when sold in liquid form
4.3.3.1.1 Packages 5 ml to 25 l

Determine the net quantity by mass (z) of the liquid fertilizing product in each package using the

method described in Clause 4.2.3.1 and Formula (1).
4.3.3.1.2 General provisions for the determination of density

Take a representative sample of the liquid fertilizing product, after thorough mixing, using a method

given in EN 1482-1:2007. The quantity of the sample shall be more than the capacity of the density

bottle.

Where the quantity of fertilizing product in each container is below the required quantity the whole

contents of a number of containers can be used to make up the sample.

For a density check to be carried out the liquid fertilizing product shall be brought to and kept at

(20 ± 1) °C during the determination process.

The method used for the determination of the density of the fertilizing product will be determined by

the physical nature of the fertilizing product.
