Pre-shaped growing media - Determination of length, width, height, volume and bulk density
This European Standard specifies a method to measure and weigh pre-shaped growing media and to calculate the volume and bulk density.
Vorgeformte Kultursubstrate - Bestimmung von Länge, Breite, Dicke, Volumen und Schüttdichte
Dieses Dokument beschreibt ein Verfahren für die Bestimmung der gemessenen Maße und der Schüttdichte vorgeformter Kultursubstrate.
"Vorgeformte Kultursubstrate" in diesem Dokument
- umfassen Festkörper, regelmäßig geformt, als haltbare Kultursubstrate verkauft, die als Kultursubstrat gebrauchsfertig sind, bei denen die Maße und Ecken stabil sind,
- beziehen keine Kegel mit ein,
- beziehen keine Kultursubstrate mit ein, die nachquellen (hydratisieren), um sich zu formen, und die mit unterschiedlichem Wassergehalt unterschiedliche Maße haben, z. B. Kokos- oder Torfplatten oder Kultursäcke.
Supports de culture préformés - Détermination de la longueur, de la largeur, de la hauteur, du volume et de la masse volumique apparente
Le présent document décrit une méthode de détermination des dimensions mesurées et de la masse volumique apparente des supports de culture préformés.
Dans ce document, « supports de culture préformés » :
- comprend les supports de culture vendus sur le marché qui sont solides, de forme régulière, stables et prêts à être utilisés comme supports de culture, dont les dimensions et les angles sont stables ;
- n’inclut pas les bouchons ;
- n’inclut pas les supports de culture solides qui ont besoin d’être hydratés pour prendre leur forme finale, dont les dimensions varient en fonction de la teneur en eau - par exemple, le coir ou les pains de tourbe ou les sacs de culture.
