EN 14346 Characterization of Waste - Calculation of Dry Matter by Determining Dry Residue or Water Content

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 14346 testing. This European Standard specifies methods for calculating the dry matter of samples for which the results of the analysis are to be calculated on a dry matter basis. Depending on the nature of the sample, the calculation is based on determining the dry residue (Method A) or determining the water content (Method B). Applies to samples containing more than 1% (m/m) of dry residue or more than 1% (m/m) of water.

In the case of effluent analysis, water is generally not considered part of the sample and results are usually related to dry matter, which can be calculated from water content or dry residue. To this end, this European standard describes two methods. The choice of method depends on the type of sample and the volatile substances it contains, excluding water.

Depending on the nature of the sample (liquid, solid or polyphase), the water content or dry residue will be determined. The results from the determination of the water content or dry residue are used to calculate the dry matter. In the case of multiphase samples, these samples should be homogenized. If homogenization is not possible, phase separation should be made according to EN 15002 and the phases should be analyzed separately.

The specifics of sample preparation are not included in this European Standard. Since the dry matter content is calculated to convert the results obtained for a sample to a dry matter basis, the dry residue or water content determination should be made on the same portions of the same test sample. With this, sample preparation is as specified in the actual analysis standard.

When performing one or more analyzes on a sample, dry matter must be determined in parallel on the same test piece so that the results of the other analysis are recalculated on a dry matter basis.
