Soil improvers and growing media - Sampling
This European Standard specifies methods for sampling soil improvers and growing media (excluding liming materials) for subsequent determination of quality and quantity. It outlines the principles to be taken into consideration when taking the sample and ensuring an adequate quantity is available for testing. This standard only applies to material in solid form, including pre-shaped media. 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. The requirements of this standard may differ from the national legal requirements for the declaration of the product concerned.
Bodenverbesserungsmittel und Kultursubstrate - Probenahme
Diese Europäische Norm legt Verfahren für die Probenahme von Bodenverbesserungsmitteln und Kultursubstraten (mit Ausnahme von Calcium-/Magnesium-Bodenverbesserungsmitteln) für die anschließende Bestimmung von Qualität und Menge fest. Sie führt Regeln auf, die bei der Probenahme zu beachten sind und stellt sicher, dass eine ausreichende Menge für die Untersuchung zur Verfügung steht. Diese Norm gilt nur für Material in fester Form, einschließlich vorgeformter Materialien. ANMERKUNG 1 Diese Norm ist für Hersteller, Käufer und Vollzugsbehörden für den Nachweis von Anforderungen an diese Produkte vorgesehen. Das festgelegte Verfahren sollte nicht für Kontrollzwecke beim Hersteller verbindlich vorgeschrieben werden. ANMERKUNG 2 Die Anforderungen dieser Norm können von den nationalen gesetzlichen Vorgaben bezüglich der Deklaration der erwähnten Produkte abweichen.
Amendements organiques et supports de culture - Echantillonnage
La présente Norme européenne décrit des méthodes d’échantillonnage des amendements organiques et des supports de culture (à l’exclusion des amendements minéraux basiques) qui permettent d'évaluer ultérieurement la qualité et la quantité de ceux-ci. Elle indique les principes à prendre en considération pour prélever l’échantillon et pour s’assurer qu’une quantité convenable pour l’essai a été prélevée. La présente norme ne s'applique qu'aux matériaux se présentant sous forme solide, y compris les supports préformés. NOTE 1 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. NOTE 2 Les exigences de la présente norme peuvent diverger par rapport aux législations nationales en ce qui concerne la déclaration des produits concernés.
Izboljševalci tal in rastni substrati - Vzorčenje
Ta evropski standard določa metode za vzorčenje izboljševalcev tal in rastnih substratov (razen sredstva za apnenje) za poznejše določanje količine in kakovosti. Opredeljuje načela, ki jih moramo upoštevati pri vzorčenju, in zagotavlja, da je za testiranje na voljo zadostna količina. Ta standard se uporablja le za materiale v trdni obliki, vključno s predhodno oblikovanimi substrati. Ta standard je namenjen za proizvajalce, kupce in organe pregona pri overjanju izjav za te izdelke. Ni nujno namenjen le za namene spremljanja proizvodnje. Zahteve iz tega standarda se lahko razlikujejo od nacionalnih zakonskih zahtev za deklaracijo zadevnega izdelka.

EN 12579:2013 (E) 4 Introduction Soil improvers and growing media are very difficult to sample because of the variety of materials used and the inhomogeneous materials involved. When packed they are also by their nature and the packaging and palletisation process subject to pressure which results in various degrees of compression which need to be counteracted prior to sampling. The task is further complicated by the variety of sampling equipment that can be used, the quantity to be represented by the sample and the degree of precision required bearing in mind the cost of testing. A suitably competent person should undertake this sampling. SIST EN 12579:2013
