This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. According to the CEN-CENELEC Internal Re
25、gulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland,

DIN EN 15002:2015-07 EN 15002:2015 (E) 5 Introduction In laboratory practice, very often different analytical procedures are bo
27、und to be applied to the laboratory sample that has been taken according to the sampling plan. For this purpose sub-sampling is bound to be applied in a way, that the different test portions are representative for the original laboratory sample with respect to the compounds of interest and the speci
28、fic analytical procedures. The representativity of the laboratory sample and of the test portions is of major importance to guarantee the quality and accuracy of analytical results. The representativity of the laboratory sample is specified by the sampling plan. This European Standard specifies the
29、correct sequence of operations to ensure the representativity of the test portions. Safety remarks: Anyone dealing with waste and sludge analysis is bound to be aware of the typical risks of that kind of material irrespective of the parameter to be determined. Waste and sludge samples may contain ha
30、zardous (e.g. toxic, reactive, flammable and infectious) substances, which can be liable to biological and/or chemical reaction. Consequently it is recommended that these samples should be handled with special care. The gases that may be produced by microbiological or chemical activity are potential
31、ly flammable and will pressurize sealed bottles. Bursting bottles are likely to result in hazardous shrapnel, dust and/or aerosol. National regulations should be followed with respect to all hazards associated with this method. DIN EN 15002:2015-07 EN 15002:2015 (E) 6 1 Scope This European Standard
32、is applicable for the preparation of representative test portions from the laboratory sample that has been taken according to the sampling plan (EN 14899), prior to physical and/or chemical analysis (e.g. preparation of eluates, extractions, digestion and/or analytical determinations) of solid (incl
33、uding monolithic material) and liquid samples and sludge. It is also applicable for the preparation of test portions from digests and eluates for the subsequent analyses. This European Standard is intended to find the correct sequence of operations and treatments to be applied to the laboratory samp
34、le in order to obtain suitable test portions in compliance with the specific requirements defined in the corresponding analytical procedures. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 drying process of removing water from a sample Note
35、1 to entry: For the purpose of test portion preparation, it may be useful to remove just the amount of water that could interfere with other processes involved (e.g. during crushing or milling). In order to minimize the alteration of the sample during test portion preparation, removing the total amo
36、unt of water present in the sample is not necessarily needed. 2.2 fraction sample obtained by procedures from the laboratory sample where the properties of interest may be unequally distributed Note 1 to entry: A fraction may consist of metal pieces, stones, etc. 2.3 granular waste waste that is nei
37、ther monolithic, liquid, gas nor sludge SOURCE: EN 12457-1:2002, 3.10 2.4 homogenisation process of combining of components, particles, layers or phases into a more homogeneous state of the original sample or pre-treated fractions of the sample in order to ensure equal distribution of substances in
38、and properties of the sample 2.5 laboratory sample sample or sub-samples sent to or received by the laboratory Note 1 to entry: When the laboratory sample is further prepared (reduced) by subdividing, mixing, grinding, or by combinations of these operations, the result is the test sample. When no pr
39、eparation of the laboratory sample is required, the laboratory sample is the test sample. A test portion is removed from the test sample for the performance of the test or for analysis. Note 2 to entry: The laboratory sample is the final sample from the point of view of sample collection but it is t
40、he initial sample from the point of view of the laboratory. DIN EN 15002:2015-07 EN 15002:2015 (E) 7 Note 3 to entry: Several laboratory samples may be prepared and sent to different laboratories or to the same laboratory for different purposes. When sent to the same laboratory, the set is generally
41、 considered as a single laboratory sample and is documented as a single sample. 2.6 moderately volatile compounds sum of semi-volatile organic compounds and moderately volatile inorganic compounds that can be lost during sample preparation Note 1 to entry: Volatile inorganic compounds of e.g. mercur
42、y, arsenic cadmium, thallium can be lost during sample preparation, e.g. heating. 2.7 moderately volatile organic compound; semi volatile organic compound organic compound having a boiling point above 180 C (at a pressure of 101 kPa) Note 1 to entry: This definition includes: a) mineral oil; b) most
43、 polycyclic aromatic hydrocarbons (PAH) (see ISO 13877); c) polychlorobiphenyls (PCB) (see ISO 10382); d) organochlorine pesticides (see ISO 10382). 2.8 monolithic waste waste which has certain minimum dimensions and physical and mechanical properties that ensure its integrity over a certain period
44、of time in the considered scenario 2.9 particle size reduction mechanical friction of the sample by milling, grinding, crushing or cutting 2.10 phase separation; fraction separation process of dividing components, particles or phases if homogenization of the sample is practically not applicable and/
45、or the analysis of different fractions or phases are appropriate 2.11 sample portion of material selected from a larger quantity of material 2.12 sub-sample sample obtained after sample size reduction of a larger sample Note 1 to entry: A sub-sample may be: a) portion of the sample obtained by selec
46、tion or division; b) the final sample of multistage sample-preparation; c) in case of monolithic sample, the sample obtained after cutting or coring. DIN EN 15002:2015-07 EN 15002:2015 (E) 8 2.13 sub-sampling process of selecting one or more sub-samples from a sample or, in case of monolithic waste,
47、 the process of cutting or coring to obtain a required regular shape 2.14 test portion; analytical portion quantity of material of proper size, for measurement of the concentration or other properties of interest, removed from the test sample Note 1 to entry: The test portion may be taken from the l
48、aboratory sample directly if no preparation of sample is required (e.g. with liquids or samples of proper homogeneity, size and fineness), but usually it is taken from the prepared test sample. 2.15 test portion of monolithic waste of regular shape test portion of monolithic waste, obtained either by cutting or coring and for which the surface area can be calculated on the basis of simple geometric formulas 2.16 test sample; analytical sample sample, prepared from the laboratory sample, from which test
