BS EN 1093-1:2008EN 1093-1:2008 (E) 4 Introduction The structure of safety standards in the field of machinery is as follows: Type-A standards (basic safety standards) giving basic concepts, principles for de
21、sign, 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 safety aspects (e.g. safety distances, surface temper
22、ature, 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 of machines. This European Standard is a type-B s
23、tandard 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 the provisions of that standard, the provisions of
24、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 hazardous substances (“pollutants“) from the machin
25、e 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; surrounding conditions, especially the air flow patte
26、rn, 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 maintenance; poor quality has generally an advers
27、e 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 workplace. Evaluation of the parameters defined in thi
28、s 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. BS EN 1093-1:2008EN 1093-1:2008 (E) 5 1 Scope This European Standard specifies parameters whic
29、h 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 fields of application and types of machines including the
30、 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 application of this document. For dated references, only the
31、 edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

33、 rate of a given pollutant um Eq flow rate of tracer emitted (measured by emitting the tracer directly into exhaust system during the first phase) NOTE 3 For further details, see EN 1093-4:1996+A1:2008, Clause 5. 3.4 separation efficiency by mass s ratio of the mass of pollutant retained by the air
34、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 air cleaning system, as a percentage, can be calculated
35、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 system against hazardous dust is measured as a function o
36、f 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 BS EN 1093-1:2008EN 1093-1:2008 (E) 7 3.6 decontamination index IAthe averag

38、perations (“the background level“). NOTE 2 The decontamination index can be calculated by the following equation: iiiiniCCCCnIfama1A1=(4) where Caireal pollutant concentration measured at specified location in the surrounding under the following condition: machine in operation, pollutant control sys

41、d 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 should be selected according to the following criteria: nature o
42、f 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 condi
43、tions to be met, in particular comparable discharge and flow patterns of the real pollutant and the tracer material, respectively. Depending on the test method, two types of pollutants shall be considered: real pollutant which may be an aerosol (solid or liquid) or a gas; BS EN 1093-1:2008EN 1093-1:
44、2008 (E) 8 tracer material simulating the real pollutant. When determining the emission rate of real pollutant without any air flow measurement, the real pollutant and the tracer material are simultaneously used. The measurements of concentrations can be carried out: in ducts together with air flow
45、rate measurements; at locations surrounding the machine under examination. 4.3 Nature of the test environment 4.3.1 General Two main types of environmental test conditions may be considered, and, in some cases, can lead to different test methods. 4.3.2 Laboratory methods 4.3.2.1 Test bench method Th
46、e tests are conducted in a cabin specially designed to these tests or measurements, and of known and limited dimensions. The cabin contains a single machine in order to avoid any interference from other machines on the pollution around the tested machine and on the air flow rate through the pollutan
47、t control system. The air flow pattern around the machine should be maintained by the provision of specified general ventilation of the cabin. NOTE In this type of method, the conditions of general ventilation, as well as the operating conditions of the machine, are fixed and, to some extent, arbitr
48、ary. Consequently, most of the time they are not representative of the actual situations encountered in practice. 4.3.2.2 Room method The tests are conducted in a room specially devoted to these tests or measurements, and located in a laboratory or on-site in an industrial setting. Only one machine
49、should be run at a time. More precise control of the general and local ventilation can be achieved than in the field. Since the location of the machine is not fixed, the air flow pattern around the machine shall be checked to determine the influence of crossdraughts. NOTE In this type of method, the conditions of general ventilation, as well as the operating conditions of the machine, are fixed and, to some extent, arbitrary. Consequently, they are not in general representative of the actual situation
