Disposable Air Filters for the Removal of Particulate Matter from Ventilating Systems

‘particulate matter’ or ‘PM’ means the mass of any material in the gas emitted by an engine that is collected on a specified filter medium after diluting the gas with clean filtered air so that the temperature does not exceed 325 K (52 °C).

Before the dates specified in Article 4(8) of this Regulation and in the case of a wall-flow diesel particulate filter (DPF), the manufacturer may choose to apply the performance monitoring requirements set out in Appendix 8 of Annex 9B to UNECE Regulation No 49 instead of the requirements set out in paragraph 2.3.2.1, if he can demonstrate with technical documentation that in case of deterioration there is a positive correlation between the loss of filtration efficiency and the loss of pressure drop (delta pressure) across the DPF under the operating conditions of the engine specified in the tests described in Appendix 8 of Annex 9B to ...[+++]UNECE Regulation No 49”. ’.

For gases, vapours, mist or dust, the type of protective equipment to be used shall be specified based on the hazard and potential for exposure, including air-purifying respirators, specifying the proper purifying element (cartridge or canister), the adequate particulate filters and the adequate masks, or self-contained breathing apparatus.

8. Considers compliance with air quality norms as laid down in EU legislation as crucial given the increase in respiratory, cardiovascular and other diseases related to air pollution, mainly resulting from transport. Takes the view that, in order to address the issue, preventive measures should be incentivised, for instance by introducing high-quality filters for the ultra-fine solid particles emitted by engines, and that incentives must be provided to renew any of the cur ...[+++]rently circulating car fleet that is not in line with the European Euro 4, Euro 5 and Euro 6 standards (the latter is due to enter into force in 2014). The reduction in emissions must not be restricted only to vehicles using new technology, i.e. with new engines, but should concern also those already in circulation. Old-generation engines can be adapted by using the new filter, with a view to achieving the low level of ultra-fine solid particles emissions of new vehicles. Favours, in particular in urban contexts, low emission zones (such as 30 areas, i.e. urban areas in which maximum vehicle speed is limited to 30 km/h) and traffic calming measures which provide an incentive for walking and cycling;
