This International Standard specifies the quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) according to the priority list of the Environmental Protection Agency, USA (EPA, 1982). This International Standard is applicable to all types of soil (field-moist or chemically dried samples), covering a wide range of PAH contamination levels.
Under the conditions specified in this International Standard, a lower limit of application of 0,01 mg/kg
(expressed as dry matter) can be ensured for each individual PAH.

This European Standard specifies the quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table 2) in sludge, soil and treated biowaste using GC-MS and HPLC-UV-DAD/FLD covering a wide range of PAH contamination levels (see also Annex B).
When using fluorescence detection, acenaphthylene cannot be measured.
(...)
The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract.
Typically, a lower limit of application of 0,01 mg/kg (expressed as dry matter) can be ensured for each individual PAH. This depends on instrument and sample.
Sludge, soil and treated biowaste can differ in properties and also in the expected contamination levels of PAHs and presence of interfering substances. These differences make it impossible to describe one general procedure. This European Standard contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. Two general lines are followed, an agitation procedure (shaking) or use of soxhlet/pressurized liquid extraction.
NOTE   Other PAH compounds can also be analysed with this method, provided suitability has been proven.

ISO 14853:2016 specifies a method for the determination of the ultimate anaerobic biodegradability of plastics by anaerobic microorganisms. The conditions described in ISO 14853 do not necessarily correspond to the optimum conditions for the maximum degree of biodegradation to occur. The test calls for exposure of the test material to sludge for a period of up to 90 d, which is longer than the normal sludge retention time (25 to 30 d) in anaerobic digesters, although digesters at industrial sites can have much longer retention times.
The method applies to the following materials:
- natural and/or synthetic polymers, copolymers or mixtures thereof;
- plastic materials which contain additives such as plasticizers, colorants or other compounds;
- water-soluble polymers;
- materials which, under the test conditions, do not inhibit the microorganisms present in the inoculum. Inhibitory effects can be determined using an inhibition control or by another appropriate method (see e.g. ISO 13641). If the test material is inhibitory to the inoculum, a lower test concentration, another inoculum or a pre-exposed inoculum can be used.

ISO 15985:2014 specifies a method for the evaluation of the ultimate anaerobic biodegradability of plastics based on organic compounds under high-solids anaerobic-digestion conditions by measurement of evolved biogas at the end of the test. This method is designed to simulate typical anaerobic digestion conditions for the organic fraction of mixed municipal solid waste. The test material is exposed in a laboratory test to a methanogenic inoculum derived from anaerobic digesters operating only on pretreated household waste. The anaerobic decomposition takes place under high-solids (more than 20 % total solids) and static non-mixed conditions. The test method is designed to yield the percentage of carbon in the test material and its rate of conversion to evolved carbon dioxide and methane (biogas).

This part of ISO 17294 specifies a method for the determination of the elements aluminium, antimony,
arsenic, barium, beryllium, bismuth, boron, cadmium, caesium, calcium, cerium, chromium, cobalt,
copper, dysprosium, erbium, gadolinium, gallium, germanium, gold, hafnium, holmium, indium, iridium,
iron, lanthanum, lead, lithium, lutetium, magnesium, manganese, mercury, molybdenum, neodymium,
nickel, palladium, phosphorus, platinum, potassium, praseodymium, rubidium, rhenium, rhodium,
ruthenium, samarium, scandium, selenium, silver, sodium, strontium, terbium, tellurium, thorium,
thallium, thulium, tin, tungsten, uranium and its isotopes, vanadium, yttrium, ytterbium, zinc and
zirconium in water (for example, drinking water, surface water, ground water, waste water and eluates).
Taking into account the specific and additionally occurring interferences, these elements can also be
determined in digests of water, sludges and sediments (for example, digests of water as described in
ISO 15587-1 or ISO 15587-2).
The working range depends on the matrix and the interferences encountered. In drinking water and
relatively unpolluted waters, the limit of quantification (xLQ) lies between 0,002 μg/l and 1,0 μg/l for
most elements. The working range typically covers concentrations between several pg/l
and mg/l depending on the element and pre-defined requirements.
The quantification limits of most elements are affected by blank contamination and depend
predominantly on the laboratory air-handling facilities available on the purity of reagents and the
cleanliness of glassware.
The lower limit of quantification is higher in cases where the determination suffers from interferences
or memory effects (see ISO 17294-1:2004, 8.2).

This European Standard specifies the pretreatment required for sludge, treated biowaste and soil (including soil-like materials), that are subject to the analysis of organic as well as inorganic chemical and physicochemical 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 and the sample pretreatment under laboratory conditions. For determining inorganic chemical and physico-chemical parameters this European Standard describes procedures to prepare: - test samples for tests under field moist conditions; - test samples for testing after drying, crushing, grinding, sieving etc.; - test samples of liquid sludge. For determination of organic compounds three pretreatment methods are specified: - a pretreatment method if volatile organic compounds are to be measured; - a pretreatment method if moderately volatile to non-volatile organic compounds are to be measured and the result of the following analysis will be accurate and reproducible; - 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. The choice of the method depends above all on the volatility of the analyte. It also depends on the particle size distribution of the material, the heterogeneity of the sample and the following analytical procedure.

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.

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.

This draft European Standard specifies a method for quantitative determination of seven selected polychlorinated biphenyls (PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 and PCB180) in sludge, treated biowaste and soil using GC-MS and GC-ECD (see Table 2).
The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract.
Under the conditions specified in this European Standard, limit of application of 1 μg/kg (expressed as dry matter) can be achieved.
Sludge and treated biowaste may differ in properties and also in the expected contamination levels of PCBs and presence of interfering substances. These differences make it impossible to describe one general procedure. This European Standard contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used.

This draft European Standard specifies a method for quantitative determination of seven polychlorinated biphenyl congeners (PCB-28, PCB-52, PCB-101, PCB-118, PCB-138, PCB-153 and PCB-180) in solid waste using high-resolution gas chromatography with electron capture or mass spectrometric detection. The basic content of this standard is identical to that of the Horizontal PCB-standard and is therefore also applicable to soil, sludge and treated bio-waste. The detection and the quantification limits in this method are dependent on sample intake, the level of interferences as well as instrumental limitations. Under the conditions specified in this standard, minimum amounts of individual PCB congeners equal or above 0,01 mg/kg dry matter can typically be determined with no interferences present.
NOTE   For the analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to EN 61619, EN 12766-1 and EN ISO 6468 respectively.
The method may be applied to the analysis of other PCB congeners not specified in the scope, but its suitability should be proven by proper in-house validation experiments.
