DIN EN 1093-1:2009-02 EN 1093-1:2008 (E) 4 Introduction The structure of safety standards in the field of machinery is as follows: Type-A standards (basic safety st
28、andards) giving basic concepts, principles for design, and general aspects that can be applied to all machinery; Type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard that can be used across a wide range of machinery: Type-B1 standards on particular safe
29、ty aspects (e.g. safety distances, surface temperature, noise); Type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure sensitive devices, guards); Type-C standards (machine safety standards) dealing with detailed safety requirements for a particular machine or group
30、of machines. This European Standard is a type-B standard as stated in EN ISO 12100-1. The provisions of this European Standard can be supplemented or modified by a type-C standard. For machines which are covered by the scope of a type-C standard and which have been designed and built according to th
31、e provisions of that standard, the provisions of that type-C standard take precedence over the provisions of this type-B standard. The concentration level of substances resulting from emission of airborne hazardous substances from machines depends upon factors including: emission rate of airborne ha
32、zardous substances (“pollutants“) from the machine under examination, depending of the type of process and the production rate of the machine; performance of the pollutant control system associated with the machine and, in the case of air recirculation, the performance of the separation system; surr
33、ounding conditions, especially the air flow pattern, which can reduce the pollution (efficient general ventilation) or increase it (disturbing air, crossdraughts); workers location in relation to the machine and its pollutant control system, and taking into account the workers movements; quality of
34、maintenance; poor quality has generally an adverse effect on the performance of the pollutant control and the separation systems. This European Standard concerns the first two points in this list and forms only one part of a comprehensive risk assessment. It is not for a risk assessment of the workp
35、lace. Evaluation of the parameters defined in this European Standard leads to an evaluation of the performance of the machine and its associated pollutant control system. This European Standard can be used as a part of verification described in EN 626-2. DIN EN 1093-1:2009-02 EN 1093-1:2008 (E) 5 1
36、Scope This European Standard specifies parameters which can be used for the assessment of the emission of pollutants from machines or the performance of the pollutant control systems integrated in machines. It gives guidance on the selection of appropriate test methods according to their various fie
37、lds of application and types of machines including the effects of measures to reduce exposures to pollutants. The test methods are given in additional parts of this European Standard (see Table 1 and Annex A). 2 Normative references The following referenced documents are indispensable for the applic

41、 s ratio of the mass of pollutant retained by the air cleaning system (m3) to the mass of pollutant entering the air cleaning system (m1) during a given period NOTE 1 For special applications the number of fibres or particles is measured instead of the mass. NOTE 2 The separation efficiency of an ai
42、r cleaning system, as a percentage, can be calculated by the following equation: 10013s=mm (3) NOTE 3 In certain cases it can be necessary to consider only that part of pollutants (e.g. size of particles) which is actually hazardous for exposed persons; e.g. separation efficiency of a separation sys
43、tem against hazardous dust is measured as a function of particle size otherwise the results are possibly not reliable for health and safety purposes. 3.5 pollutant concentration parameter Pcthe measured concentration of a given pollutant in defined position(s) near the machine DIN EN 1093-1:2009-02

48、ds 4.1 General When particle size distribution is determined at the same time as pollutant concentration, an assessment parameter for each size fraction can be defined. For the determination of each assessment parameter (see Clause 3), different test methods can be considered. The test methods shoul
49、d be selected according to the following criteria: nature of pollutant used; nature of the test environment. 4.2 Nature of pollutant used As far as possible, the real pollutant should be used for the testing. However, in some cases tracer techniques allow a more convenient testing. The addition of tracer material to the real pollutant requires several conditions to be met, in particular comparable discharge and flow patterns of the real pollutant and the tracer material, respectively.
