01/990 - Proposal for a EP and Council Decision establishing the list of priority substances in the field of water policy COM(2000)47 New version of 01/990: PE-CONS 3645/01 (2001-09-04) : PE and Council Decision on List of Priority Substances for WFD

This standard will provide a technique for determination of the strain-to-fracture of coatings deposited on a wide variety of substrates. Additionally, it will  under certain circumstances provide data on coating adhesion.

This future standard will specify a method for the determination of phthalates in water after solid phase extraction and gas chromatography - mass spectrometry. The method is applicable to the determination of phthalates (a list of common phthalates is included in CD 18856) in ground water, surface water, waste water and drinking water in mass concentrations between 0,02 µg/l and 0,150 µg/l, depending on the individual substance. The applicability of the method to other phthalates not given in the table is not excluded, but shall be verified in each case.

ISO 17353:2004 specifies a method for the identification and quantification of monobutyltin, dibutyltin, tributyltin, tetrabutyltin, monooctyltin, dioctyltin, triphenyltin, tricyclohexyltin compounds and/or cations in drinking water, surface water and wastewater containing not more than 2 g/l of suspended material. The working range is 10 ng/l to 1 000 ng/l. The respective anions are not determined.
This method can also be applicable to other compounds such as monomethyltin, dimethyltin, monophenyltin and diphenyltin compounds and/or cations. ISO 17353:2004 is also applicable to marine water.

ISO 18856:2004 specifies a method for the determination of phthalates in water after solid phase extraction and gas chromatography/mass spectrometry.
This method is applicable to the determination of phthalates in ground water, surface water, wastewater and drinking water in mass concentrations ranging from above 0,02 microgram per litre up to 0,150 microgram per litre, depending on the individual substance and the value of the blank.
The applicability of this method to other phthalates not specified is not excluded, but it is necessary to determine its applicability in each case.

With a scope of describing a manual method of making measurements for the determination of volume fraction of major phases in advanced technical ceramics using micrographs of polished and etched sections, overlaying a square grid of lines, and counting the number of intersection lying other each phase.

The method will give a general guide for the determination of metals by flameless AAS.

ISO 17993:2002 specifies a method using high performance liquid chromatography (HPLC) with fluorescence detection for the determination of 15 selected polycyclic aromatic hydrocarbons (PAH) [naphthalene, acenaphthene, phenanthrene, fluoranthene, benzo(a)anthracene, benzo(b)fluoranthene, benzo(a)pyrene, dibenzo(a,h)anthracene, fluorene, anthracene, pyrene, chrysene, benzo(k)fluoranthene, indeno(1,2,3-cd)pyrene, benzo(ghi)perylene] in drinking and ground water in mass concentrations greater than 0,005 microgram/litre (for each single compound) and surface waters in mass concentrations above 0,01 microgram/litre.
This method is, with some modification, also suitable for the analysis of waste water. This method may be applicable to other PAH, provided the method is validated for each case.

ISO 15586:2003 includes principles and procedures for the determination of trace levels of: Ag, Al, As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sb, Se, Tl, V, and Zn in surface water, ground water, drinking water, wastewater and sediments, using atomic absorption spectrometry with electrothermal atomization in a graphite furnace. The method is applicable to the determination of low concentrations of elements.
The detection limit of the method for each element depends on the sample matrix as well as of the instrument, the type of atomizer and the use of chemical modifiers. For water samples with a simple matrix (i.e. low concentration of dissolved solids and particles), the method detection limits will be close to instrument detection limits. The minimum acceptable detection limit values for a 20-microlitre sample volume are specified.
