该欧洲标准描述了确定矩形预制成长培养基的长度，宽度，高度，体积和体积密度的方法。 在本标准中，“预成型培养基”: - 包括销售的固体，规则形状，稳定的生长介质，其可以用作生长介质，其尺寸和角部是稳定的，并且表面和边缘彼此垂直 - 包括矿棉和聚氨酯产品; - 不包括必须水合的固体生长介质，其尺寸随水含量的变化而变化，例如椰子或泥炭板或生长袋。 该标准适用的块的最小线性尺寸（长度，宽度或高度）为40 mm，最大尺寸为2 000 mm

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.
