This European Standard describes a method of determination of length, width, height, volume and bulk density of rectangular pre-shaped growing media.

In this standard \'pre-shaped growing media\':

includes solid, regular shaped, stable growing media sold, which are ready for use as a growing media, where the dimensions and corners are stable, and the surfaces and edges are perpendicular to each other – including mineral wool and polyurethane products;
does not include solid growing media that has to be hydrated for it to form, varies in dimension with varying water content – for example coir or peat slabs or growing bags.

The minimum linear dimension (length, width or height) for blocks to which this standard applies is 40 mm, and the maximum dimension is 2 000 mm.
