18、12-07 EN 1425:2012 (E) 4 Introduction The properties of bituminous binders depend on a number of factors, such as type (pure bitumen, bitumen emulsion, cutback or fluxed bitumen) grade and temperature. These physical properties are determined by the appropriate test methods. The perceptible properti
19、es, such as appearance and odour, are determined by sensorial observation. It is, for instance, quite simple to distinguish by smell flux oil from a bituminous binder. Often other properties, such as homogeneity, cannot be determined by visual inspection alone due to the high consistency (viscosity)
20、 of the bituminous binder. However, in the case of bituminous binders such as bitumen emulsions, cutback or fluxed bitumen, the presence of lumps, agglomerates or sediments can be observed. DIN EN 1425:2012-07 EN 1425:2012 (E) 5 1 Scope This European Standard specifies a method for the determination
21、 of the perceptible properties of bituminous binders at ambient temperature prior to testing for other properties. WARNING The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use.
22、 It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are
23、 indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 58, Bitumen and bituminous binders Sampling bituminous binders 3 Terms and definitions For the purpos
24、es of this document, the following terms and definitions apply. 3.1 perceptible property property observed using one of the senses 3.2 laboratory sample sample intended for laboratory tests Note 1 to entry: The laboratory sample can be a spot sample, a composite sample or a part thereof (divided sam
25、ple). 4 Apparatus 4.1 Glass rod. 4.2 Fume-cupboard. 5 Sampling The laboratory samples shall be sampled in accordance with EN 58. The samples shall be marked unambiguously and a record shall be kept of the date, origin and type or grade. 6 Procedure 6.1 Examine the sample in its original container at
26、 approximately ambient temperature or below and record the following: a) unique sample identification of supplier; b) additional information included in labelling, if appropriate; DIN EN 1425:2012-07 EN 1425:2012 (E) 6 c) sample quantity; d) type and state of packing (report any damage to the sample
27、 or sample container). NOTE If a unique sample identification is missing, the supplier should be contacted before further testing of the sample. 6.2 Place the unopened sample in the fume-cupboard (4.2) if it is volatile or of unknown volatility. Open the container at ambient temperature. If any unus
28、ual odour is apparent, close the container, replace the sample in the fume-cupboard and report the findings. 6.3 Examine the sample at approximately ambient temperature for the following perceptible properties: a) appearance of the surface (e.g. shiny, dull, coloured); b) presence of foreign materia
29、ls (e.g. free water, dust, rust); c) consistency (e.g. liquid or solid); d) homogeneity of liquid binders, (by gently stirring with the glass rod (4.1) and recording the presence of any lumps, agglomerates, sediments etc.); e) odour (the usual bitumen odour or other typical odour, e.g. from tar or s
30、olvent). WARNING Personnel who assess the odour characteristic of the samples should be aware of the correct sniffing procedure and the hazards of potentially dangerous chemicals. It is unlikely that occasional sniffing of refined bitumen will be harmful, but frequent testing of unknown materials (w
31、hich may contain tar or harmful solvents) should not be done repeatedly by any one individual. The results of the sensorial examination shall conform to the perceptible properties expected of the sample indicated on the sample container. If conformity exists, the material shall be accepted for furth
32、er testing. If the material does not conform to the perceptible properties expected, the container shall be closed immediately, and the person requesting the analysis of the sample shall be contacted and informed of the findings before the sample is handled any further. 7 Test report The test report
33、 shall contain at least the following information: a) type and complete identification of the sample under test; b) reference to this European Standard; c) sample quantity; d) type and state of packing e) results of the examinations (see 6.2 and 6.3); f) any deviation, by agreement or otherwise, from the procedure specified; g) date of the test.
