DINEN 15051-1:2014-03EN 15051-1:2013 (E) 4 Introduction The control of dust emissions during the handling and transportation of bulk materials is an important consideration in the design and operation of ma

26、ny industrial processes. Excessive airborne dust levels in workplaces are undesirable for several reasons: they can cause adverse health effects to the workers; their control can involve the use of costly ventilation and filtration systems; they can contaminate machinery and products; they can be co

27、stly in terms of product losses; It is therefore advantageous for occupational hygienists and process engineers to have relevant information about the propensity of bulk materials to produce airborne dust (the “dustiness” of the bulk material) so that risks can be evaluated, controlled and minimized

28、. No single method of dustiness testing is likely to represent and reproduce the various types of processing and handling used in industry. Therefore a number of dustiness testing methods are in use in different industries. Different methods use different test apparatus and measuring principles, and

29、 express results in different ways. Methods that do not separate the dust cloud produced into the three health-related size fractions - inhalable, thoracic and respirable dust - can serve the needs of manufacturing industry for process and batch control, but give limited information on the health ha

30、zard due to the dustiness of the bulk material. Dustiness is a relative term and the measurement obtained will depend on the test apparatus used, the condition and properties of the tested bulk material and various environmental variables. The test and the variables therefore need to be closely spec

31、ified to ensure reproducibility. Recognising the above, it was concluded that there was a need for standardized methods to measure the dustiness of bulk materials, based on the biologically relevant aerosol fractions defined in EN 481. This European Standard, together with EN 15051-2 and EN 15051-3,

32、 establishes test methods that classify the dustiness, in terms of health-related fractions, of solid bulk materials. The dustiness classification is intended to provide users (e.g. manufacturers, producers, occupational hygienists and workers) with information on the potential for dust emissions wh

33、en the bulk material is handled or processed in workplaces. It provides the manufacturers of bulk materials with information that can help to improve their products. It allows the users of the bulk materials to assess the effects of pre-treatments, and also to select less dusty products, if availabl

34、e. Although this European Standard does not discuss the analysis of dust released from bulk materials (except in terms of health-related fractions), the test method produces samples with the potential for chemical analysis of the contents. If methods to evaluate dustiness for bulk materials handled

35、in other ways are deemed of importance, CEN/TC 137 could be approached for adopting a new work item, e.g. more specific industrial handling procedures. The level of the dustiness generally depends on material-specific and process-specific parameters. The most important material-specific parameters a

36、re the particle size distribution of the bulk material, its bulk density, its moisture content (“bulk material moisture content”), its chemical composition, DINEN 15051-1:2014-03EN 15051-1:2013(E)5 physical characteristics like electrostatic charge distribution. Process-specific parameters are mainl

37、y determined by the type of handling and are essentially determined by the type and level of energy that leads to dust release, and the duration of the energy effect. This European Standard was originally developed based on the results of the European project SMT4-CT96-2074 Development of a Method f

38、or Dustiness Testing (see 1). This project investigated the dustiness of 12 bulk materials, with the intention to test as wide a range of bulk materials as possible, i.e. magnitude of dustiness, industrial sectors, chemical composition and particle size distribution. In this revised version, importa

39、nt comments from industrial users of the standard (e.g. Industrial Minerals Association), a number of research papers (for example, 2 and 3) and the potential influence of the expanding database of dustiness results have been taken into account. DINEN 15051-1:2014-03EN 15051-1:2013 (E) 6 1 Scope Thi

40、s European Standard specifies the environmental conditions, the sample handling and analytical procedures and the method of calculating and presenting the results. Reasons are given for the need for more than one method and advice is given on the choice of method to be used. This European Standard e

41、stablishes a classification scheme for dustiness to provide a standardised way to express and communicate the results to users of the bulk materials. Details of the scheme for each method are given in EN 15051-2 and EN 15051-3. This European Standard is applicable to powdered, granular or pelletized

42、 bulk materials. This European Standard is not applicable to test the dust released during mechanical reduction of solid bulk materials (e.g. cut, crushed) or to test application procedures for the bulk materials. Figure 1 gives a flow chart to provide the user of this European Standard a route thro

43、ugh the necessary stages that need to be taken to obtain values of the dustiness of a given bulk material.
