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.

This European Standard specifies methods for the determination of a quantity of soil improvers and growing media in bulk and in packages. This is a reference method, which is designed with an appropriate precision level so that it can be used to validate any quantity declaration made. This standard is applicable to material that is in solid form, reconstituted if necessary, but not to blocks sold as such by dimension; for these, see EN 15761. This method is not applicable for material with more than 10 % (V/V) of particles greater than 60 mm in size; for these, see EN 15238. The requirements of this standard may differ from the national legal requirements for the declaration of the products concerned. Where there is no legal requirement to use this method, for example in quantity control of packaged product, then it is permissible for any other methods to be used so long as these other methods can be demonstrated to be comparable with this standard method in giving the same quantity with the same precision. Material which has become excessively wet and which cannot be easily broken down into a flowable material will not be suitable for the determination of quantity and may not give a representative result. However, because of the diverse nature and bulk density of these materials, it is not possible to quantify what is ‘excessive’. 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.

This European Standard specifies a routine method for determining the organic matter and the ash content of soil improvers and growing media.
NOTE 1   This method is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
NOTE 2   The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.

This European standard specifies an instrumental method for the routine determination of electrical conductivity in a water extract of a soil improver or growing medium. The determination is carried out to obtain an indication of the content of water soluble electrolytes in either soil improvers or growing media.
NOTE 1   This method is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
NOTE 2   The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.

This European Standard specifies an instrumental method for the routine determination of pH in a suspension of soil improvers or growing media.
NOTE 1   This method is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
NOTE 2   The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.

This European Standard specifies requirements and procedures to determine the compostability or anaerobic treatability of plastic materials by addressing four characteristics:
I)      biodegradability,
II)      disintegration during biological treatment,
III)      effect on the biological treatment process and
IV)      effect on the quality of the resulting compost.
NOTE   For packaging EN 13432 applies.

This European Standard specifies a method for the determination of nitrogen in soil improvers and growing media. The dry combustion method was developed originally as a manual method by Dumas [5]. Its application is improved greatly due to the use of modern automated equipment and is applicable to all forms of nitrogen.
The 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.

This European Standard specifies a method for the determination of nitrogen in soil improvers and growing media. The Kjeldahl method determines ammonium-N, nitrate-N, nitrite-N and organic N content of soil improvers and growing media. Nitrogen in N-N-linkages, N-O-linkages and some heterocyclics (especially pyridine) is only partially determined. [6], [7], [8]
The 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.

This European Standard specifies a method for the routine extraction of aqua regia soluble elements (as listed in annex B) from soil improvers or growing media. Materials containing more than about 28 % (m/m) organic matter will require treatment with additional nitric acid. With high solute concentrations in extract solutions, spectral interference's and background enhancement should be expected.
The method is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
NOTE 1   Aqua regia will not totally dissolve most soil improvers or growing media, and the efficiency of extraction for particular elements differs from element to element. Such efficiency might also differ for the same element in different matrices.  Elements extractable in aqua regia cannot therefore, be described as "Totals"; conversely they cannot be regarded as the "bio-available" fraction, as the extraction procedure is too vigorous to represent any biological process.
NOTE 2      The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.

This European Standard specifies requirements and procedures to determine the compostability and anaerobic treatability of packaging and packaging materials by addressing four characteristics: 1) biodegradability; 2) disintegration during biological treatment; 3) effect on the biological treatment process; 4) effect on the quality of the resulting compost. In case of a packaging formed by different components, some of which are compostable and some other not, the packaging itself, as a whole is not compostable.
