Safety of machinery - Evaluation of the emission of airborne hazardous substances - Part 1: Selection of test methods

This European Standard specifies parameters which can be used for the assessment of the emission of pollutants from machines or the performance of the pollution control systems integrated in machines. It gives guidance on the selection of appropriate test methods according to their various fields of applications and types of machines including the effects of measures to reduce exposures to pollutants. The test methods are given in additional parts of this standard (see Table 1 and Annex A).
This European Standard is not applicable for certain types of off-the-road vehicles powered by internal combustion engines which are also subject to the Machinery Directive.

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 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. 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 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 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 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;  surrounding conditions, especially the air flow pattern, which can reduce the pollution (efficient general ventilation) or increase it (disturbing air, crossdraughts);  worker's 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 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 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. SIST EN 1093-1:2009

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 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 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 edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 626-2, Safety of machinery – Reduction of risks to health from hazardous substances emitted by machinery – Part 2: Methodology leading to verification procedures EN ISO 12100-1:2003, Safety of machinery – Basic concepts, general principles for design – Part 1: Basic terminology, methodology (ISO 12100-1:2003) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following apply. 3.1 uncontrolled emission rate of a given pollutant um& mass of pollutant emitted from the machine into the space around the machine per unit of time NOTE Any measures to reduce the air pollution around the machine (e.g. capture devices, containment equipment, wetting process) should not be used or should be de-activated. 3.2 controlled emission rate of a given pollutant km& mass of pollutant emitted from the machine into the space around the machine per unit of time, taking into account the effects of measures to reduce the air pollution NOTE Any measures to reduce the air pollution around the machine (e.g. capture devices, containment equipment, wetting process) should be used or activated. SIST EN 1093-1:2009

EN 1093-1:2008 (E) 6 3.3 capture efficiency cη ratio of the mass flow rate of a given pollutant directly collected by the pollutant control system to the uncontrolled mass flow rate of this pollutant emitted from the machine NOTE 1 The capture efficiency, as a percentage, can be calculated by the following equation: 100ukuc×−=mmm&&&η (1) This equation is applicable only if um& – km& represents the pollutant mass flow rate directly captured. This parameter is not usable when the amount of emission is affected by the control system. NOTE 2 Where the pollutant control system is an exhaust system and provided comparable discharge and flow patterns of the real pollutant can be simulated by a tracer technique, the equation becomes: 100ECc×=qqη (2) where Cq flow rate of tracer collected by exhaust system during operation; 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 sη 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 air cleaning system, as a percentage, can be calculated by the following equation: 10013s×=mm
