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 standards) giving basic concepts, principles for design, and general aspects that can be applied to all
12、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 temperature, noise); Type-B2 standards on safeguards (e.g.
13、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 standard as stated in EN ISO 12100-1. The provisions o
14、f 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 that type-C standard take precedence over the provisi
15、ons 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 machine under examination, depending of the type of process
16、 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 pattern, which can reduce the pollution (efficient general
17、 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 adverse effect on the performance of the pollutant control
18、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 this European Standard leads to an evaluation of the per
19、formance 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. EN 1093-1:2008 (E) 5 1 Scope This European Standard specifies parameters which can be used for the assessment of the emission of pollutants from ma
20、chines 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 effects of measures to reduce exposures to pollutants. The test metho
21、ds 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.
