PD CEN/TS 16675:2014CEN/TS 16675:2014 (E) 4 Introduction Disposal of some types of waste requires stabilisation/soli

16、dification to reduce the impact and/or comply with regulatory requirements. The characterisation of waste is an essential step for the assessment of a potential final destination, especially in case of landfilling and associated potential hazards. Based on its properties, a stabilised/solidified was

17、te material may be allocated to a landfill for granular waste or a landfill for monolithic waste. Information on certain physical properties of a given stabilised/solidified waste material is required to determine if it can be classified as a monolithic material and to select appropriate leaching te

18、st method(s) and landfilling options for that waste. This technical specification describes test methods applicable to assessment of these physical properties. WARNING Anyone dealing with waste and sludge analysis should be aware of the typical risks of that kind of material irrespective of the para

19、meter to be determined. Waste and sludge samples may contain hazardous (e.g. toxic, reactive, flammable, infectious) substances, which can be liable to biological and/or chemical reaction. Consequently these samples should be handled with special care. Gases which may be produced by microbiological

20、or chemical activity are potentially flammable and will pressurise 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 the methods in this technical specification. PD CEN

21、/TS 16675:2014CEN/TS 16675:2014 (E) 5 1 Scope This Technical Specification provides methods, which can be used to assess the monolithic character of a stabilised/solidified waste, with respect to landfilling. Information on the monolithic character is required to enable the choice of appropriate lea

22、ching tests for determination of the release of different substances from stabilised/solidified waste under specified (landfilling) conditions. This document includes several physical and/or chemical test methods each addressing different aspects of monolithic character. The selection of methods req

23、uired for an assessment of the monolithic character of a stabilised/solidified waste may vary, depending on the scenario to be addressed or it may be specified in regulation. Rather than describing the procedures and methods in detail this document refers to existing standards and provides some guid

24、ance on their use on stabilised/solidified waste materials. This Technical Specification does not address issues related to health and safety. The following procedures and methods are included in this document: test to determine unconfined compressive strength; test to determine permeability; test t

25、o determine the loss of mass by dissolution or disintegration; test to determine expansion; test to determine the content of organic matter; test to determine freeze/thaw effects. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are

41、c character of a specific waste material provided in this document shall address the conditions imposed by the relevant landfill scenario(s). In general, there is an intention to produce a monolithic waste form which will maintain its integrity under specified conditions over a specified time span f

42、or the landfill. The following procedures allow assessment of the monolithic character of a waste sample of regular shape in order to enable selection of appropriate test methods and interpretation models for the determination of the release of substances from the waste under landfilling conditions.

43、 Some of the procedures may also be used to determine if the waste material fulfils applicable geotechnical requirements for landfilling. If for some reason one or more of the procedures are not considered necessary for a specific purpose, the justification for that shall be given in the test report

44、. PD CEN/TS 16675:2014CEN/TS 16675:2014 (E) 8 5 Equipment and reagents The equipment and reagents to be used are listed in the selected methods and procedures. 6 Sampling and sample preparation EN 15002 provides general instructions on the preparation of test portions from a laboratory sample of mon

45、olithic waste. Each of the selected test methods will, however, include specific requirements on sample preparation which shall be followed. 7 Procedures 7.1 General One or more of the following procedures shall be used to assess the monolithic character of a stabilised/solidified waste material. 7.

46、2 Unconfined compressive strength (UCS) A monolithic material to be placed in a landfill shall have sufficient bearing capacity to support trucks and compacting equipment on the surface and sufficient strength to support its own mass. The waste in a landfill is usually enclosed in a confined space w

47、hich has a stabilising effect on its physical stability, also in the longer term. The requirements on strength for monolithic waste to be landfilled will generally be substantially lower than those for monolithic waste forms to utilised, e.g. as bricks which are often used under unconfined condition

48、s. Measurement of the unconfined compressive strength will allow an assessment of whether or not the bearing capacity of a monolithic waste material is sufficient in relation to a specific landfill scenario. The test may be carried out both before and after water exposure. The following standard sha

49、ll be used: EN 12390-3. The results shall be reported in accordance with the requirements in the standard. For the purpose of assessment of the monolithic character of the waste material, the unconfined compressive strength (UCS) shall be reported in N/mm2(MPa). 7.3 Permeability The mechanism by which substances are released from a monolithic waste material depends to a large extent on the pattern of the flow of water around or through the material. Under specified external conditions the flow pattern is dependent on the permeability of the
