8、 stage, however it attracted sufficient support from other national standards bodies to gain acceptance and publication. The UK committee is of the opinion that the scope of this TR is not in line with the original mandate for the work. The scope of CEN/TR 17105 gives the impression that the TR is a

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 re

27、sponsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This Technical Report gives guidance for the combination of the recommended horizontal leaching tests harmonized b

28、y CEN/TC 351 with existing biological test methods for the assessment of ecotoxicological properties of eluates of construction products. Guidance regarding biological tests for the effects of construction products on soil organisms is also included. This document takes into account relevant informa

29、tion that had become available by March 2016. This document is intended as easy-to-use guidance especially for the Group of Notified Bodies, test laboratories and EOTA. Technical committees for construction products (product TCs) are expected to benefit from the information given in the report, if t

30、hey have been mandated to address ecotoxicity in their product standards or if they are interested to include ecotoxicity in a dossier prepared in the context of qualifications for a “without testing” status. PD CEN/TR 17105:2017CEN/TR 17105:2017 (E) 5 Introduction Ecotoxicological analysis of const

31、ruction products and their eluates and biodegradability of the organic substances in eluates belong to the essential characteristics covered by the basic requirement for construction works “hygiene, health and the environment” from Annex 1 of the Construction Products Regulation 1. Under the Europea

32、n Commissions mandate M/366 (see mandate database at http:/ec.europa.eu/growth/tools-databases/mandates) and according to the Indicative List (see https:/www.nen.nl/ under search term CEN/TC 351) which specifies the mandated parameters, CEN/TC 351 has been assigned to deal with these essential chara

33、cteristics. Now that the mandated leaching tests from CEN/TC 351 (CEN/TS 16637-2, CEN/TS 16637-3) 2, 3 are available and also work on the methods for the chemical analysis of eluates has progressed, CEN/TC 351 has included a Technical Report on ecotoxicity / biodegradability in its active programme

34、of work. The background for the decision to cover this topic was presented in an open expert workshop in Brussels in April 2014. The conclusions and recommendations of the workshop are presented in Annex A. The regulatory background for the work is explained in Annex B and information on its possibl

35、e interface with data generated under the REACH Regulation is given in Annex C. In the context of harmonized specifications for construction products currently only Germany requests performance data on ecotoxicity/biodegradability in certain cases, i.e. when and where a chemical analysis and assessm

36、ent of the eluates of construction products is considered to be too onerous or not possible due to the lack of analytical methods/data. Examples of products addressed are fire protective products and fire stopping and fire sealing products depending on their ingredients. Ecotoxicity assessment is co

37、nsidered to be especially relevant for the building and for the demolition phase in the life cycle of construction works. These life cycle phases have been covered by the framework of the Construction Products Regulation since 2013. The majority of existing internationally harmonized ecotoxicity tes

38、ts were developed firstly to assess the ecotoxic potential of chemicals, waste water or contaminated soils. More recently, these tests have been successfully applied to waste and waste eluates 4 to 7. These methods can be applied with some modifications for the ecotoxicological characterization of c

39、onstruction products and their eluates. Several studies as well as an international round robin test have been conducted to validate some test methods for construction product eluates and the results have been used as background information 8 to 13. The validation of the methods for construction pro

40、ducts is not yet complete. Further validation of the recommended test procedure is needed, if this TR is intended to be further developed into a CEN/TS or EN (to be decided later). PD CEN/TR 17105:2017CEN/TR 17105:2017 (E) 6 1 Scope This Technical Report gives information on existing methods to test

41、 ecotoxicity of construction products. Information is given on how to combine recommended leaching tests with biological tests for the aquatic environment and how to avoid possible problems, when performing biological tests. Also suitable terrestrial tests on granular construction products diluted w

42、ith artificial soil are proposed for a minimum test battery. Reference has been made as far as possible to existing International and European Standards and guidelines. The test procedure described in this Technical Report is technically suitable for all construction product eluates and for terrestr

43、ial tests on granular or paste-like construction products. However, from the point of view of test efficiency it is recommended mainly for products containing organics or polymers in case chemical analysis alone is not deemed to be sufficient. For inorganic products the chemical analysis is seen as

44、straightforward in construction product eluates and therefore the added value of data received through ecotoxicity tests is seen as limited. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 biodegradation mineralization of organic compounds by
