Soil improvers and growing media - Determination of physical properties - Dry bulk density, air volume, water volume, shrinkage value and total pore space
This European Standard describes an instrumental method for the routine determination of the physical properties, dry bulk density, water volume, air volume, shrinkage value and total pore space of soil improvers or growing media.
This European Standard is not suitable for those materials which are very coarse, which do not make proper capillary contact or those which are pre-formed and non-particulate and have closed porosity. It is applicable to materials with particles 25 mm and/or flexible fibres 80 mm.
This method is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
NOTE The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.
Bodenverbesserungsmittel und Kultursubstrate - Bestimmung der physikalischen Eigenschaften - Rohdichte (trocken), Luftkapazität, Wasserkapazität, Schrumpfungswert und Gesamtporenvolumen
Diese Europäische Norm legt ein gerätegestütztes Verfahren zur routinemäßigen Bestimmung der physikalischen Eigenschaften Rohdichte (trocken), Wasserkapazität, Luftkapazität, Schrumpfungswert und Gesamtporenvolumen von Bodenverbesserungsmitteln oder Kultursubstraten fest. Diese Europäische Norm ist ungeeignet für sehr grobe Materialien, die keinen ausreichenden Kapillarkontakt ausbilden oder solche die vorgeformt und nicht gekörnt vorliegen und deren Poren verschlossen sind. Sie gilt für Materialien mit Teilchen < +/- 25 mm und/oder biegsame Fasern < +/- 80 mm. Dieses Verfahren gilt nicht für Calcium-/Magnesium-Bodenverbesserungsmittel und vorgeformte Materialien wie Mineralwollplatten und Schaumplatten. ANMERKUNG Die Anforderungen der Norm können von den nationalen gesetzlichen Vorgaben bezüglich der Deklaration der erwähnten Produkte abweichen.
Amendements du sol et supports de culture - Détermination des propriétés physiques - Masse volumique apparente sèche, volume d'air, volume d'eau, valeur de rétraction et porosité totale
La présente Norme européenne spécifie une méthode instrumentale pour la détermination des propriétés physiques, à savoir masse volumique apparente sèche, volume d’eau, volume d’air, valeur de rétraction et porosité totale des amendements du sol et supports de culture.
La présente Norme européenne ne convient pas pour les matériaux très grossiers qui ne créent pas de phénomène de capillarité ni pour ceux qui sont préformés et sans agrégats distincts et dont les pores sont fermés. Elle est applicable aux matériaux ayant des particules 25 mm et/ou des fibres souples 80 mm.
La présente méthode n’est pas applicable aux amendements calciques et/ou magnésiens basiques, ni aux matériaux préformés tels que les blocs de laine minérale et de mousse.
NOTE Les exigences de la norme peuvent diverger par rapport aux législations nationales en ce qui concerne la déclaration des produits concernés.
Izboljševalci tal in rastni substrati - Določanje fizikalnih lastnosti - Prostorninska gostota (suha), kapaciteta za zrak, kapaciteta za vodo, vrednost skrčenja in celotna poroznost
V tem evropskem standardu je opisana instrumentalna metoda za rutinsko določanje fizikalnih lastnosti, prostorninske gostote (suhe), kapacitete za vodo, kapacitete za zrak, vrednosti skrčenja in celotne poroznosti izboljševalcev tal ali rastnih substratov. Ta evropski standard ni ustrezen za zelo grobe materiale, materiale, ki ne vzpostavijo dobrega kapilarnega stika ali predhodno oblikovane materiale, ki nimajo delcev in imajo zaprto poroznost. Uporablja se za materiale z delci ≤ 25 mm in/ali prožnimi vlakni ≤ 80 mm.

As each ring is individually made it is necessary to determine the volume (V1), record the mass (m1) and identify each lower sample ring. The volume shall be determined by measuring the mean height (at least quadruplicate measurements) (h1) and mean diameter (d1) of the sample rings with a calliper gauge (At least triplicate measurements; top, middle and bottom). 5.1.2.2 Removable gauze-retaining ring or collar 20 mm high and 7,5 mm to 8,5 mm larger than the outer diameter of the sample ring. 5.1.2.3 Non-biodegradable synthetic gauze with a mesh size of about 0,1 mm. 5.1.3 Upper ring 5.1.3.1 Upper ring having the same internal diameter as the ring prepared in (see 5.1.2.1) and height
(53 ± 1) mm. 5.1.3.2 Collar - fixed on the ring permitting the upper cylinder to be secured to the lower cylinder for the duration of the test.
5.2 Plastic tube, of approximately 14 cm diameter and 14 cm high to give a volume of about 2 l. Tightly stretch and secure the gauze (see 5.1.2.3) to one end of the tube by means of an elastic band. 5.3 Water bath, capable of holding at least 4 plastic tubes (see 5.2) standing on a coarse mesh and capable of being filled with water to the top of the plastic tubes. 5.4 Sand suction table (see Figure A.3) Prepare the sand suction table for example in accordance with Annex A, using the fine sand to obtain the required suction. The pressure head in the plastic tubes (–50 cm water = –5 kPa) is measured from the SIST EN 13041:2012
–100 cm water, equivalent to –1 kPa, –5 kPa and –10 kPa, respectively) is measured from the middle of the lower ring (see Figure A.3). The setting of the pressure head can be checked with a tensiometer or pressure transducer. 5.5 Ventilated drying oven set at (103 ± 2) °C. 5.6 Analytical balance with a scale interval of 0,1 g. 5.7 Shallow vessel, spoon or scoop approximately 50 ml capacity. 6 Preparation Prepare the laboratory sample in accordance with 8.4 of EN 13040:2007. 7 Procedure 7.1 Moistening, saturating and equilibration at –50 cm water (–5 kPa) pressure head 7.1.1 Fill at least 2 tubes (see 5.2) with the test portion taking care to preven
