Test methods for assessing the performance of gas-phase air cleaning media and devices for general ventilation - Part 2: Gas-phase air cleaning devices (GPACD) (ISO 10121-2:2013); German version EN ISO 10121-2:2013
Methode zur Leistungsermittlung von Medien und Vorrichtungen zur Reinigung der Gasphase für die allgemeine Lüftung - Teil 2: Einrichtungen zur Reinigung der Gasphase (GPACD) (ISO 10121-2:2013); Deutsche Fassung EN ISO 10121-2:2013
Overview
This standard defines relevant requirements set out in Annex I of the EC Machinery Directive 2006/42/EC, relating to machines which were placed on the European Economic Area (EEA) market for the first time, with the intent of simplifying the means of proving conformity with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Communities, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called presumption of conformity). This part of ISO 10121 provides an objective test method to estimate the performance of any full size gas filtration device (GPACD) for general filtration regardless of media or technique used in the device. This part of ISO 10121 shall serve to avoid relating the test data to internal parameters altogether. The benefit with this approach is that customers of GPACDs will be able to concentrate on price/performance and suppliers (providers) will have access to a normative and objective test standard that will not require the release of proprietary information or reverse engineering of the product. To ensure objectivity for test equipment suppliers, no specific design of the test apparatus is specified. Instead requirements of apparatus properties and validation tests are specified. However, different design examples in present use are outlined. This part of ISO 10121 can also be used with technologies such as scrubbers, absorbers, non-sorptive devices or packed columns as long as they fit into the test apparatus, can be meaningfully judged by the test method and are intended for general ventilation applications in both residential and non-residential (commercial and administrative) buildings Nuclear and military applications are specifically excluded. This standard contains the German version of EN ISO 10121-2:2013 which has been prepared by Technical Committee ISO/TC 142 "Cleaning equipment for air and other gases" in collaboration with Technical Committee CEN/TC 195 "Air filters for general air cleaning" at the European Committee for Standardization (CEN). The national interests during the preparation were represented by NA 060-09-21 AA "SpA CEN/TC 195 und ISO/TC 142" ("national mirror committee CEN/TC 195 and ISO/TC 142") of Section "Allgemeine Lufttechnik" ("General ventilation") of the Mechanical Engineering Standards Committee (NAM) at DIN. Representatives of manufacturers and users of air filters, and of research and testing institutes, contributed to this standard.
