Test method for assessing the performance of gas-phase air cleaning media and devices for general ventilation - Part 1: Gas-phase air cleaning media (ISO 10121-1:2014); German version EN ISO 10121-1:2014

Title (German)

Methode zur Leistungsermittlung von Medien und Vorrichtungen zur Reinigung der Gasphase für die allgemeine Lüftung - Teil 1: Medien zur Reinigung der Gasphase (ISO 10121-1:2014); Deutsche Fassung EN ISO 10121-1:2014

Overview

This standard defines relevant requirements set out in Annex I of the EU 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 these requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Union, the manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called presumption of conformity). The ISO 10121 series aims to provide laboratory test methods for media and devices which are used for removal of gas-phase contaminants from air in general ventilation. It consists of two parts: - EN ISO 10121-1 covers three different media configurations and is targeted towards giving a standardized interface between media suppliers and producers of air cleaning devices. It may also be used between media suppliers and end customers with regards to loose fill media properties. - EN ISO 10121-2 aims to give a standardized interface between suppliers of air cleaning devices and end customers seeking the best performing and most economical way to employ gas-phase filtration. EN ISO 10121-1 aims to provide an objective laboratory test method, a suggested apparatus, normative test sections and normative tests for evaluation of three different solid gas-phase air cleaning media (GPACM) or GPACM configurations for use in gas-phase air cleaning devices intended for general filtration applications. It is specifically intended for challenge testing and not for general material evaluation or pore system characterization. The three different types of GPACM identified in Part 1 of ISO 10121 are GPACM-LF (particles of different shape and size intended for example for Loose Fill applications), GPACM-FL (Flat sheet fabric intended for example for flat one layer, pleated or bag type devices) and GPACM-TS (three dimensional structures that are many times thicker than flat sheet and for example used as finished elements in a device). The tests are conducted in an air stream and the GPACM configurations are challenged with test gases under steady-state conditions. Since elevated gas challenge concentrations (relative to general ventilation applications) are used, test data should be used to compare GPACM within the same configuration and not for the purpose of predicting performance in a real situation. It is also not implied that different GPACM configurations can be directly compared. The primary intention is to be able to compare like GPACM configurations to like, not between GPACM configurations. Testing of complete devices is described in ISO 10121-2. The standard contains the German version of EN ISO 10121-1:2013 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 "Luftfilter" ("Air filters") in the Technical Section General Ventilation of the Standards Committee Mechanical Engineering (NAM) at DIN. Representatives of interested parties, including manufacturers of particulate air filters, users and research and testing institutes were involved in the preparation of the standard.
