This European Standard shall be given the status of a national standard, either by publication

    17、 of an identical text or by endorsement, at the latest by October 2015, and conflicting national standards shall be withdrawn at the latest by October 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall

    18、not be held responsible for identifying any or all such patent rights. This document supersedes EN 15002:2006. 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 Regulations, the natio

    19、nal 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, Italy, Latvia, Lith

BS EN 15002:2015EN 15002:2015 (E) 5 Introduction In laboratory practice, very often different analytical procedures are bound to be applied to the

    21、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 specific analytical procedures

    22、. 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 correct sequence of opera

    23、tions 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 hazardous (e.g. toxic, reac

    24、tive, 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 potentially flammable and will pre

    25、ssurize 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. BS EN 15002:2015EN 15002:2015 (E) 6 1 Scope This European Standard is applicable for the preparat

    26、ion 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 (including monolithic material) and

    27、 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 sample in order to obtain suitable

    28、 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 1 to entry: For the purpose of

    29、 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 amount of water present in the sa

    30、mple 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 neither monolithic, liquid, gas n

    31、or 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 and properties of the sample 2

    32、.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 preparation of the laboratory sa

    33、mple 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 the initial sample from the poi

    34、nt of view of the laboratory. BS EN 15002:2015EN 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 considered as a single laboratory

    35、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. mercury, arsenic cadmium, thallium can be

    36、 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 polycyclic aromatic hydrocarbons (

    37、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 of time in the considered scenario

    38、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/or the analysis of different fracti

    39、ons 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 selection or division; b) the final samp

    40、le of multistage sample-preparation; c) in case of monolithic sample, the sample obtained after cutting or coring. BS EN 15002:2015EN 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, the process of cutting or coring to obt

    41、ain 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 laboratory sample directly if no preparat

    42、ion 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 su

    43、rface 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 portions are removed for testing or for analysis 2.17 volatile organic compound compound which is liquid at room temperature (20 C)

    44、and which generally has a boiling point below 180 C Note 1 to entry: This includes single-ring aromatic hydrocarbons and other low boiling halogenated hydrocarbons, which are used as solvents or fuels, and some degradation products. SOURCE: ISO 10381-7:2005, 3.23, modified The original term abbrevia

    45、tion and example have been retrieved. 3 Equipment For the purpose of preparation of test portions from the laboratory samples appropriate equipment shall be chosen depending on the procedures selected according to Annex A. In the selection of the type of treatment techniques, one should keep in mind

    46、 that each of them has some potential impact on analytical results. It can generate loss of the analytes of interest, introduce contamination or alter the physical-chemical properties of the sample. All glassware and devices that come in contact with the sample shall be made out of a suitable materi

    47、al, chemically compatible with the sample, selected in order to minimize contamination of samples and adsorption or absorption of the analytes (e.g. plastic materials for inorganic elemental analysis, quartz or glass for volatile and organic analytes). Care shall be taken to ensure a good cleaning,

    48、in order to avoid cross-contamination of samples. An informative list of appropriate equipment for the sample treatment procedures is given in Annex C. 4 Interferences and sources of error The (sub)-sample shall be re-homogenized after any particle size reduction operation that may have resulted in

    49、segregation of different sized particles. Care should be taken to avoid loss of material and contamination of the sample via the air, by dust, by the use of the apparatus (e.g. from the ambient laboratory atmosphere or between samples stored or processed close to one another). BS EN 15002:2015EN 15002:2015 (E) 9 Three types of contamination could occur from the apparatus: a) abrasion; b) cross-contamination; c) chemical release. It is recommended to perform treatment of waste material in a separate room used only for this purpose, especially crushing or sie
