41、 EN 12697-4:2015 (E)DIN EN 12697-4:2015-097 Introduction WARNING The method described in this European Standard may require the use of dichloromethane (methylene chloride), 1.1.1 trichlorethane, benzene, trichlorethylene, xylene, toluene or other solvent capable of dissolving bitumen. These solvents

42、 are hazardous to health and are subject to occupational exposure limits as detailed in relevant legislation and regulations. Exposure levels are related to both handling procedures and ventilation provision and it is emphasized that adequate training should be given to staff employed in the usage o

43、f these substances. EN 12697-4:2015 (E)DIN EN 12697-4:2015-098 1 Scope This European Standard specifies a test method for the recovery of soluble bitumen from bituminous mixtures from pavements in a form suitable for further testing. The procedure is suitable for the recovery of paving grade bitumen

44、 and is also suitable for mixtures containing volatile matter such as cut-back bitumen but the results may be less precise. This European Standard is the reference method for mixtures containing volatile matter, but the rotary evaporator procedure (see EN 12697-3) for mixtures with paving grade bitu
