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.

Die Norm EN 17817:2023 behandelt die Bestimmung der Menge von Düngemitteln, Kalkungsmaterialien und Inhibitoren. Sie legt spezielle Methoden fest zur Ermittlung der Mengen von festen und flüssigen Düngemittelprodukten, einschließlich organischer Düngemittel, organo-mineraler Düngemittel, anorganischer Düngemittel, Kalkungsmaterialien und Inhibitoren, die in Verpackungen, Behältern oder in loser Form vorliegen. Der umfassende Anwendungsbereich dieser Norm gewährleistet eine präzise Quantifizierung der relevanten Düngemittelprodukte und bietet somit eine essentielle Grundlage für die Landwirtschaft und den Gartenbau. Ein herausragendes Merkmal der EN 17817:2023 ist ihre Anwendbarkeit auf Düngemittelmischungen, in denen die oben genannten Produkte den höchsten prozentualen Anteil an der Mischung nach Masse oder Volumen ausmachen. Diese Festlegung erleichtert die Konformität und Einheitlichkeit in der Anwendung der Standards. Somit wird sichergestellt, dass die Nutzer wissen, welche Methode zur Mengenbestimmung bei ihren spezifischen Produkten anzuwenden ist. Die Regelung, dass im Falle von gleichen Mengen bei den Komponenten der Mischungen der Anwender entscheidet, welcher Standard anzuwenden ist, fördert zudem die Flexibilität und Anpassungsfähigkeit in der industriellen Praxis. Ein weiterer wichtiger Aspekt dieser Norm ist die klare Abgrenzung von ihrem Anwendungsbereich. Die Norm ist nicht auf die Mengenbestimmung von Wachstumsmedien, Bodenverbesserern und Pflanzenbiostimulanzien anwendbar, was die Nutzer davor schützt, fehlerhafte Standards auf nicht relevante Produkte anzuwenden. Dies verringert Missverständnisse und potenzielle Fehlerquellen in der Anwendung, was die Relevanz der Norm in der Praxis unterstreicht. Die Norm EN 17817:2023 ist somit eine unverzichtbare Richtlinie für die Bestimmung der Menge von Düngemitteln, Kalkungsmaterialien und Inhibitoren, die durch ihre klare Struktur und spezifischen Anwendungshinweise nicht nur die Qualitätssicherung in der Landwirtschaft unterstützt, sondern auch zur nachhaltigen Nutzung von Düngemitteln beiträgt.
La norme EN 17817:2023 a pour objectif l'harmonisation des méthodes de détermination de la quantité des produits de fertilisation solides et liquides tels que les engrais organiques, organo-minéraux, inorganiques, ainsi que les matériaux de calcaire et les inhibiteurs, que ce soit en paquets, en conteneurs ou en vrac. Le champ d'application de ce document est particulièrement pertinent pour les blends de produits fertilisants où les engrais organiques, organo-minéraux, inorganiques, matériaux de calcaire et inhibiteurs constituent la plus grande proportion, que ce soit par masse ou volume, ou dans le cas des formats liquides par masse sèche. Un des points forts de cette norme réside dans sa capacité à fournir des méthodes précises et fiables pour la quantification des produits fertilisants, permettant aux utilisateurs de garantir la conformité et la qualité de leurs matières premières. Cette norme assure également que, lors de la composition de blends, les utilisateurs aient la flexibilité nécessaire pour choisir la norme appropriée lorsque les composants sont en quantités égales, rendant ainsi le cadre d'application plus adaptable aux différentes situations. Par ailleurs, il convient de noter que la norme exclut spécifiquement la détermination de la quantité des milieux de culture, des améliorants de sols et des biostimulants végétaux. Cela permet de se concentrer uniquement sur les systèmes d'engrais traditionnels et d'inhibiteurs, renforçant ainsi la précision des applications de la norme et son importance dans un secteur en constante évolution. En somme, le document SIST EN 17817:2024 se révèle essentiel pour tous les acteurs de l'industrie des fertilisants, étant donné son approche systématique et rigoureuse, ainsi que sa pertinence face aux exigences croissantes en matière de qualité et de durabilité des produits agricoles.
The EN 17817:2023 standard provides a comprehensive framework for determining the quantity of various solid and liquid fertilizing products, including organic fertilizers, organo-mineral fertilizers, inorganic fertilizers, liming materials, and inhibitors. With a focus on ensuring accuracy in measurement, this standard is essential for manufacturers and suppliers in the agricultural industry who need to declare quantities with confidence. One of the key strengths of this standard is its clear delineation of applicability, which allows users to understand when and how to apply the standard based on the composition of the fertilizing products. By specifying that the methods outlined are applicable only when the pollutants such as organic fertilizers or other specified types constitute the highest percentage by mass or volume in a blend, it effectively narrows the scope to relevant scenarios. This targeted approach enhances the usefulness of the standard, ensuring that it aligns with practical applications in the field. Additionally, the exclusion of certain products such as growing media and soil improvers from the standard's scope provides clarity and prevents ambiguity regarding its application. This specificity ensures that users are not misled and can focus on the appropriate guidelines for fertilizers, liming materials, and inhibitors. The standard's relevance in today's context is underscored by the increasing demand for standardized practices in the agricultural sector, particularly as it relates to sustainability and environmental responsibility. By providing robust methods for quantity determination, EN 17817:2023 aids in compliance with regulatory requirements while promoting transparency in product listings. In conclusion, the standardization document SIST EN 17817:2024 is a significant addition to the existing guidelines for fertilizing products, reinforcing the importance of accurate quantity determination within the agriculture supply chain. Its scope, strengths, and practical relevance make it a crucial resource for anyone involved in the production, distribution, or regulation of fertilizers and related materials.
