Sludge, treated biowaste and soil - Guidance for sample pretreatment cen:proj:27067

Scope

This European standard specifies the pretreatment required for sludges, treated biowastes and soils (including soil materials), that are to be subjected to analysis of organic as well as inorganic chemical and physico-chemical parameters.
The pretreatment of samples aims at preparing a (small) test sample which is representative for the original sample.
This European standard describes the pretreatment which could be performed under field conditions if necessary (see clause 8) and the sample pretreatment under laboratory conditions (clause 10).
For determining inorganic chemical and physico-chemical parameters this European standard describes procedures to achieve (10.2):
• subsamples for tests under field moist conditions;
• subsamples for testing after drying, crushing, grinding, sieving etc.;
• subsamples of liquid sludge
For determination of organic compounds three pretreatment methods are specified:
 A pretreatment method if volatile organic compounds are to be measured (10.3.2).
 A pretreatment method if moderately volatile to non-volatile organic compounds are to be measured and the result of the following analysis must be accurate and reproducible (10.3.3).
 A pretreatment method if moderately volatile to non-volatile organic compounds are to be measured and the extraction procedure prescribes a field moist sample or if only indicative results are required (10.3.4).
The choice depends above all on the volatility of the organic compounds under analysis. It also depends on the particle size distribution of the material (see 5 and 8.3), the heterogeneity of the sample and the following analytical procedure.
This European Standard is applicable for samples of which the following compounds and/or characteristics may need to be determined:
- polycyclic aromatic hydrocarbons (PAH),
- polychlorinated biphenyles (PCB),
- organochlorine pesticides (OCP),
- phenols and chlorophenols,
- phthalates,
- nonylphenol-Polyethoxylates (NPnE),
