34、 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 5 EN 12697-14:2000 prEN 12697-38, Common equipment and calibration The applicability of this European Standard is described in the product standards for bituminous mixtures. No existing European Standard is superseded. WARNING The method described in
35、this European Standard may require the use of dichloromethane (methylene chloride). This solvent is hazardous to health and is subject to occupational exposure limits as described in relevant legislation and regulations. Exposure levels are related to both handling procedures and ventilation provisi
36、on and it is emphasised that adequate training should be given to staff employed in the use of this substances. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Re
37、public, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 1Scope This European Standard describes a test method for the determination of the water content of samples of bituminous mixtures
38、. The test method is suitable for checking conformity to a product specification, where required. 2Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text an
39、d the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (i
40、ncluding amendments). prEN 12697-27:2000, Bituminous mixtures - Test methods for hot mix asphalt Part 27: Sampling. 3Reagents Solvents used in this European Standard shall be capable of dissolving bitumen and distilling the solution to recover the water present. The solvents shall not decompose in w
41、ater and shall have a boiling point of not more than 85 0C to prevent the water from boiling. NOTE 1 Currently all hydrocarbon solvents are regarded as “hazardous” and “environmentally unfriendly” to varying degrees. NOTE 2 Until such time as there is an agreed CEN policy with regard to their usage,
42、 each member state should specify its preferred solvent taking into account the Montreal Protocol and views of its own Regulatory Bodies (see also “Warning” in the foreword).

43、:2000 NOTE 3 When trichloroethylene is recovered by distillation for further use, care should be taken to ensure that the solvent still conforms to the appropriate requirements. In particular, acidity may develop and a useful precaution is to store the solvent over calcium oxide in coloured glass or
44、 suitable metal containers. NOTE 4 The solvent should be checked regularly to ensure that it is “dry”. The method consists of preheating a probe attached to a temperature measuring device before measuring the temperature at stated depths in a number of locations while the asphalt is in one of severa
45、l different places and then calculating the average. 4Apparatus NOTE 1 Apparatus should be calibrated and traceable as recommended in prEN 12697-38:2000. NOTE 2 A suitable assembly is shown in Figure 1. 4.1 Hot extractor consisting of a cylindrical container made from non-corrodible or brass gauze o
46、f about 1 mm to 2 mm aperture size or, alternatively, a spun copper tube with a ledge at the bottom of which a removable brass gauze disc rests. The container is retained, by any suitable means, in position in the top two-thirds of a metal pot. The pot is flanged and fitted with a secure cover and s
47、uitable jointing gasket. The cover is held in the position so that the joint between the container and the cover is solvent tight. NOTE 1 The essential features of the construction are indicated in Figures 2 and 3. NOTE 2 It is advantageous to have containers and pots of more than one size, the size
48、 employed being appropriate to quantity of material taken for analysis. 4.2 12,5 ml graduated receiver. NOTE The receiver may be fitted with ground glass joints; in this case an adapter may be necessary to connect the receiver to the cover of the pot. 4.3 Water-cooled reflux condenser with a cooled
49、length of at least 200 mm and the lower end ground at an angle of 450, to the axis of the condenser. 4.4 Balance, capable of weighing a test portion to an accuracy of 0,05 % of its mass. 4.5 Heater, such as an electric hotplate. NOTE Gas rings should not be used because of the risk of toxic fumes arising from decomposition of any free solvent vapour and the corrosion of the pot if made of steel. 4.6 Closed container.
