EN 196-10:2016 (E) DIN EN 196-10:2016-11 4 Introduction This European Standard specifies the reference method for the determination of water-soluble chromiu

25、m (VI) content of cement that consists of two stages, an extraction procedure and an analysis of the filtered extract. This European Standard test method has adopted the principle that extraction is carried out under conditions approximating as closely as possible to those during the commercial use

26、of cement. Consequently extraction is by standard mortar and subsequent filtration. Other extraction procedures based on paste extraction have traditionally been used and are included in Annexes C and D for use as screening tests, in factory production control or laboratories not having access to eq

27、uipment specified in EN 196-1 for the production of mortar. The use of paste extraction is outside the normal conditions of use of cement. This European Standard test method has adopted the principle of analysis by spectrophotometry. The procedures set down generally permit the analysis to be carrie

28、d out without the need for an oxidation step. On rare occasions some cements may contain reducing species, not controlled by the routine method, that interfere with the analysis and require an oxidation step. Inter-laboratory testing has demonstrated that it is necessary to include an initial assess

29、ment test in order to observe the effects on the analysis. By comparing the results obtained from the method with and without the oxidation step, it can be determined whether, for that cement, the reference method should include the oxidation step. Other instrumental procedures may be used for the a

30、nalysis of the filtered extract provided they are calibrated against the analysis of the filtered extract using the reference procedure. In case of dispute or failure to comply with a regulatory limit only the reference method shall be used. This European Standard test method has drawn heavily on th

31、e Danish Standard DS 1020 and the extraction procedure developed by the French cement industry association ATILH. Careful consideration has been given to the details of the German TRGS 613 method developed by Germanys Hazardous Materials Committee in support of Industrial Regulations for Hazardous M

32、aterials. Notice was also taken of the British Cement Association inherent colour method; the draft method produced by CEN/TC 193/WG1, reference N680, for cement-based adhesives; European Standard method EN 420 for protective gloves; and to the method, reference ID-215, developed by the Occupational

33、 Safety and Health Administration, Salt Lake City, UT, USA. The USA Portland Cement Association, Research and Development report Serial No. 2554 “Review and evaluation of analytical methods for the determination of hexavalent chromium in hydraulic cements and clinker” by Waldemar A. Klemm was found

34、to be most helpful in resolving technical issues. CEN/TR 14589 confirmed that chromium species and solubilities are sensitive to pH and redox conditions and care has been taken to address these in this European Standard by controlling sample exposure to air, by adding the indicator to the alkaline f

35、iltered extract and by precisely specifying the pH for the analytical procedure. This European Standard test method was developed in order to provide a reference test method for use in the evaluation of compliance of cement with the requirements in entry 47 to Annex XVII of Regulation (EC) 1907/2006

36、1of the European Parliament and of the Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). A system for the evaluation of compliance of cement is set out in Annex A. 1Note that Regulation (EC) No 1907/2006 is impacted by Commission

37、 Regulation (EU) No 126/2013 of 13 February 2013 amending Annex XVII to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). EN 196-10:2016 (E) DIN EN 196-10:2016-11 5 1 Scope This part of EN 1

38、96 specifies the method for the determination of the water-soluble chromium (VI) content of cement. A reference method is described consisting of two stages, an extraction procedure and an analysis of the filtered extract. Guidance on other extraction procedures, suitable for screening tests, for fa

39、ctory production control or other purposes, is given but in case of dispute or failure to comply with a regulatory limit only the reference method is used. The reference method has alternatives whereby the filtered extract may be subjected to an oxidation step or not. The criteria by which the appro

40、priate procedure is selected are set down. Other instrumental procedures may be used for the analysis of the filtered extract provided they are calibrated against the analysis of the filtered extract using the reference procedure. In the case of a dispute, only the reference method is used. Annex A

41、sets out a normative procedure to be followed in case this test method is used as the basis for evaluation of conformity of a cement with the regulatory limit in Regulation (EC) 1907/20062. This part of EN 196 describes a method that applies to cements. It may have wider applicability but this would

42、 need to be verified by testing on a product-by-product basis. Guidance in the possible application of this European Standard to the determination of the water-soluble chromium (VI) content of cement-containing preparations is given in Annex B. Annexes C and D provide information on other test proce

43、dures based on paste extraction and thus depart from the performance of cement in its normal conditions of use. They may be carried out with or without the oxidation process. Users should be aware that results using these methods might be significantly different to those obtained by the reference me

44、thod. In the case of dispute or failure to comply with the regulatory limit only the reference method is used. Annex E provides guidance on a method for determination of the excess reducing agent content of cement as used in the factory internal control system of some countries. Manufacturers using

45、such an internal control method should ensure themselves of the relevance of results in comparison with testing by the reference method. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
