EN 17087:2019 (E) 6 European foreword This document (EN 17087:2019) has been prepared by Technical Committee CEN/TC 351 “Construction products: assessment of release of dangerous substances”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2019, and conflicting national standards shall be withdrawn at the latest by August 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a standardization request given to CEN by the European Commission and the European Free Trade Association. According to the CEN-CENELEC Internal Regulations, the national standards organisations 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, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 17087:2019



EN 17087:2019 (E) 7 Introduction In laboratory practice, very often different analytical procedures have to be applied to the laboratory sample that has been taken according to the sampling plan. For this purpose, subsampling needs to be applied in such 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. Ensuring the laboratory sample and test portions are representative is of major importance to guarantee the quality and accuracy of analytical results. The representativeness of the laboratory sample is specified by the sampling plan. This European Standard specifies the correct sequence of operations to ensure the representativeness of the test portions. NOTE This document is based on EN 15002 as developed by CEN/TC 292, for the preparation of test portions from the laboratory sample for the characterization of waste. SIST EN 17087:2019



EN 17087:2019 (E) 8 1 Scope This document is applicable for the preparation of representative test portions from the laboratory sample that has been taken as specified in respective product standards and in CEN/TR 16220, prior to testing of release and analysis of content of construction products. This document is intended to specify the sequence of operations and treatments to be applied to the laboratory sample in order to obtain suitable test portions in compliance with the specific requirements defined in the corresponding test methods and analytical procedures. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 14507:2003, Soil quality — Pretreatment of samples for determination of organic contaminants 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: — IEC Electropedia: available at http://www.electropedia.org/ — ISO Online browsing platform: available at http://www.iso.org/obp 3.1 construction product any product or kit which is produced and placed on the market for incorporation in a permanent manner in construction works or parts thereof and the performance of which has an effect on the performance of the construction works with respect to the basic requirements for constructions works Note 1 to entry: Often simply referred to as “products”. Construction products may be placed on the market e.g. as liquid, granular, monolithic, sheet-like, plate-like products, shaped products or powders. They can consist of a single material or of more than one material (composite products, complex products). [SOURCE: EN 16687:2015, 2.1.1] 3.2 digest solution resulting from acid digestion of a sample [SOURCE: EN 16687:2015, 3.2.8] 3.3 drying process of removing liquid from a sample Note 1 to entry: For the purpose of test portion preparation, it can be useful to remove just the amount of liquid 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 liquid present in the sample is not necessarily needed. SIST EN 17087:2019



EN 17087:2019 (E) 9 3.4 homogenisation process of combining of components, particles or layers into a more homogeneous state of the original samples (in the case of composite samples) or pre-treated fractions of samples in order to ensure equal distribution of substances in and properties of the sample 3.5 laboratory sample sample or sub-sample(s) sent to or received by the laboratory Note 1 to entry: When the laboratory sample is further prepared by subdividing, cutting, sawing, coring, mixing, drying, grinding, and curing or by combinations of these operations, the result is the test sample. When no preparation 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/ analysis or for the preparation of a test specimen. 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 point of view of the laboratory. [SOURCE: EN 16687:2015, 3.2.1] 3.6 moderately volatile organic compounds 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 (PAH) (see ISO 13859); c) polychlorobiphenyls (PCB) (see ISO 10382); d) organochlorine pesticides (see ISO 10382). [SOURCE: EN 15002:2015, 2.7] 3.7 monolithic construction product product which has certain minimum dimensions and physical and mechanical properties that ensure its integrity over a certain period of time in the intended conditions of use Note 1 to entry: Monolithic products are usually tested by a dynamic surface leaching test. [SOURCE: EN 16687:2015, 2.2.4] 3.8 particle size reduction mechanical decrease of the particle size of the sample by milling, grinding, crushing or cutting Note 1 to entry: For a monolithic construction product, the application of a jaw crusher is generally preferred.

[SOURCE: EN 16687:2015, 3.1.5] 3.10 sub-sample sample obtained by procedures in which the items of interest are randomly distributed in parts of equal or unequal size Note 1 to entry: A sub-sample may be: a) portion of the sample obtained by selection or division; b) the final sample of multistage sample-preparation. 3.11 sub-sampling process of selecting one or more sub-samples from a sample 3.12 test portion; analytical portion amount of the test sample taken for testing/ analysis purposes, usually of known weight or volume EXAMPLE 1 A bag of aggregates is delivered to the laboratory (the laboratory sample).
