Soil improvers and growing media - Determination of a quantity

This European Standard specifies methods for the determination of a quantity of soil improvers and growing media in bulk and in packages. This is a reference method, which is designed with an appropriate precision level so that it can be used to validate any quantity declaration made. This standard is applicable to material that is in solid form, reconstituted if necessary, but not to blocks sold as such by dimension; for these, see EN 15761. This method is not applicable for material with more than 10 % (V/V) of particles greater than 60 mm in size; for these, see EN 15238. The requirements of this standard may differ from the national legal requirements for the declaration of the products concerned. Where there is no legal requirement to use this method, for example in quantity control of packaged product, then it is permissible for any other methods to be used so long as these other methods can be demonstrated to be comparable with this standard method in giving the same quantity with the same precision. Material which has become excessively wet and which cannot be easily broken down into a flowable material will not be suitable for the determination of quantity and may not give a representative result. However, because of the diverse nature and bulk density of these materials, it is not possible to quantify what is ‘excessive’. This standard is intended to be used by manufacturers, buyers and enforcement agencies in verifying claims made for these products. It is not intended that it should necessarily be used for the purpose of manufacturing control.

Bodenverbesserungsmittel und Kultursubstrate - Bestimmung der Menge

Diese Europäische Norm legt Verfahren für die Bestimmung der Menge von Bodenverbesserungsmitteln und
Kultursubstraten bei loser Lieferung (Liefermenge) und von Fertigpackungen (Füllmenge) fest. Dies ist ein
Referenzverfahren, das mit einem geeigneten Präzisionsniveau gestaltet worden ist, damit es zur Validierung
von Mengendeklarationen verwendet werden kann.
Diese Norm gilt für Material in fester Form, das erforderlichenfalls rekonstituiert ist, jedoch nicht für Blöcke, die
als solche nach Maß verkauft werden, hierfür siehe EN 157611) Dieses Verfahren gilt nicht für Material mit
über 10 % Volumenanteil an Korngrößen über 60 mm, hierfür siehe EN 152382).
ANMERKUNG 1 Die Anforderungen dieser Norm können von den nationalen gesetzlichen Vorgaben bezüglich der
Deklaration der erwähnten Produkte abweichen.
ANMERKUNG 2 Falls es keine gesetzliche Anforderung gibt, dieses Verfahren anzuwenden, zum Beispiel in der
Füllengenkontrolle von verpackten Produkten, ist es erlaubt, jedes andere Verfahren anzuwenden, so lange gezeigt
werden kann, dass diese anderen Verfahren die gleiche Menge mit der gleichen Präzision, bezogen auf diese Norm,
ergeben.
ANMERKUNG 3 Material, das übermäßig nass geworden ist und nicht einfach in rieselfähiges Material zerkleinert
werden kann, ist nicht für die Bestimmung der Menge geeignet und wird auch kein repräsentatives analytisches Ergebnis
liefern. Auf Grund der verschiedenartigen Natur und Schüttdichte dieser Materialien ist es jedoch nicht möglich, zu
quantifizieren, was "übermäßig" ist.
ANMERKUNG 4 Dieses Verfahren ist zur Anwendung durch Hersteller, Käufer und Überwachungsbehörden zur Prüfung
von Beanstandungen vorgesehen, die für diese Produkte vorgebracht worden sind. Es ist nicht vorgesehen, dass es
zwangsläufig für Zwecke der Herstellungskontrolle angewendet werden sollte.

Amendements organiques et supports de culture - Détermination de la quantité

La présente Norme européenne décrit des méthodes de détermination de la quantité de support de culture ou d’amendement organique en vrac comme en emballage conditionné. Il s’agit d’une méthode de référence conçue avec un niveau de fidélité approprié, de sorte qu'elle peut être utilisée pour valider n'importe quelle déclaration de quantité.
La présente norme concerne les produits sous forme solide éventuellement reconstitués mais pas les produits sous forme de bloc vendu en l'état (pour ceux-ci, voir l’EN 15761). La présente méthode n’est pas applicable aux produits dont plus de 10 % (V/V) des particules ont une taille supérieure à 60 mm (pour ceux-ci, voir l’EN 15238).
Les exigences de la présente norme peuvent diverger par rapport aux législations nationales en ce qui concerne la déclaration des produits concernés.
Lorsqu’il n'y a aucune exigence légale d'utiliser la présente méthode, par exemple en termes de contrôle de la quantité de produit emballé, il est alors possible d'utiliser d'autres méthodes pourvu qu'elles permettent d’obtenir la même quantité avec la même fidélité que la présente méthode.
Un matériau excessivement humide et difficilement émiettable en un matériau fluide ne conviendra pas à la détermination de la quantité et peut ne pas donner un résultat représentatif. Cependant, en raison de variabilité de la nature et de la masse volumique apparente de ces matériaux, il n’est pas possible de quantifier ce qui est ‘excessif’.
La présente norme est destinée à être utilisée par les fabricants, les acheteurs et les organismes de contrôle chargés de vérifier les allégations à propos des produits. Il n'est pas prévu qu'elle doive nécessairement être utilisée à des fins de contrôle de fabrication.

Izboljševalci tal in rastni substrati - Določevanje količine

Ta evropski standard določa metode za določevanje količine izboljševalcev tal in rastnih substratov v razsutem ali zapakiranem stanju. To je referenčna metoda, ki je zasnovana z ustrezno ravnjo natančnosti, tako da se lahko uporabi za validacijo katere koli izjave o količini. Ta standard velja za material v trdni obliki, ki je po potrebi vnovič določen, vendar ne za kose, ki se prodajajo glede na velikost; za te glejte EN 15761. Ta metoda ne velja za material, ki ima več kot 10 % (V/V) delcev, večjih od 60 mm; za te glejte EN 15238. Zahteve iz tega standarda se lahko razlikujejo od nacionalnih zakonskih zahtev za deklaracijo zadevnih izdelkov. Če zakonska zahteva za uporabo te metode ne obstaja, na primer pri spremljanju količine pakiranega izdelka, se lahko uporabi katera koli druga metoda, vendar le, če je mogoče prikazati primerljivost teh drugih metod s to standardno metodo pri omogočanju enake količine z enako natančnostjo. Material, ki se je pretirano zmočil in ki se ne more enostavno razgraditi v pretočen material, ni primeren za določanje količine in morda ne bo dal reprezentativnega rezultata. Zaradi različne narave in prostorninske gostote teh materialov ni mogoče določiti, kaj je »pretirano«. Ta standard je namenjen za proizvajalce, kupce in organe pregona pri overjanju izjav za te izdelke. Ni nujno namenjen le za namene spremljanja proizvodnje.

EN 12580:2013 (E) 4 Introduction Soil improvers and growing media are generally traded by volume as the weight of the product can be greatly affected by the moisture content. It is important for both consumers and traders to know the volume of product being traded. Furthermore, for the cultivation of plants, it is the volume of the product, and not the weight, that is generally important. The volume is calculated from knowing the weight and bulk density of the product, the latter being determined from weighing a known reference volume of product. For those materials traded by reference to its mass, this document recognises the effects the moisture content can have on the quantity declared. Therefore the principle is that for such transactions any weight should be accompanied by the moisture content so that the solid matter content can be calculated. As some soil improvers and growing media are compressible (and some may be presented in compressed blocks or bales), it is important that this aspect be addressed in the method of determining the bulk density. A suitably competent person should undertake this testing. Even for materials traded by volume, the moisture content can have an effect as high moisture levels increase agglomerations, can reduce the ability to decompress or reconstitute materials, reduce their flow characteristics and give higher apparent bulk densities and lower volumes. The preparation and sampling of all materials prior to quantity determination is covered in EN 12579. Quantity determination will be performed as soon as possible after preparation and sampling.

Where there is no legal requirement to use this method, for example in quantity control of packaged product, then it is permissible for any other methods to be used so long as these other methods can be demonstrated to be comparable with this standard method in giving the same quantity with the same precision. Material which has become excessively wet and which cannot be easily broken down into a flowable material will not be suitable for the determination of quantity and may not give a representative result.
