This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once

Where the International Standards and publications referred to are not also DIN ISO Standards with the same number, there are no national standards available. In add
11、ition to the legal units of measurement, this standard also uses the unit “lbs”. It should, however, be noted that the Gesetz ber Einheiten im Messwesen (German Law on units in metrology) prohibits the use of this unit for official and commercial purposes in Germany.

DIN EN ISO 10121-2:2013-08 EN ISO 10121-2:2013 (E) 3 IntroductionThere is an increasi
28、ng use and need for gas-phase filtration in general filtration applications. This demand can be expected to increase rapidly due to the increasing pollution problems in the world together with an increasing awareness that solutions to the problems are available in the form of filtration devices or,
29、phrased more technically, gas-phase air cleaning devices (GPACD). The performance of devices relies to a large extent on the performance of a gas-phase air cleaning media (GPACM) incorporated in the device. Still applications and device performance are often poorly understood by the users and suppli
30、ers of such media and devices. Media tests may also be adequate to offer data for real applications if actual low concentrations (weeks) can be used in the test, provided that the geometrical configuration, packing density and flow conditions of the small-scale test specimen are equal to those used
31、in the real applications. Such tests are however not included in the scope of ISO 10121. ISO 10121 attempts to increase understanding and communication by supplying a more standardized interface between media suppliers, device suppliers and end users. At present, standards exist for general ventilat
32、ion in Japan1by JIS, automotive filters by ISO4, in-duct sorptive media gas-phase air-cleaning devices by ASHRAE7and for adsorptive media by ASHRAE8and ASTM9. No international standard for general filtration exists today.This part of ISO 10121 prescribes methods, test equipment, data interpretation
33、and reporting for gas-phase air cleaning devices intended for the removal of gas-phase contamination from air in general ventilation applications.In addition, information is given in a number of annexes: Annex A describes the normative validation procedure in detail in a tabulated form. Annex B give
34、s a list of possible test gases, generation sources and suggests suitable analysis equipment for common test gases in addition to reference techniques given for the simplified benchmark setup in Clause 5.5. Annex C discusses different test stand designs.A general introduction to molecular filtration
35、 and molecular filtration testing can be found in the scientific literature.ISO 10121 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: ISO 10121-1 covers three different media
36、 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. This part of ISO 10121 aims to give a standardized interfa
37、ce between suppliers of air cleaning devices and end customers seeking the most cost efficient way to employ gas-phase filtration.DIN EN ISO 10121-2:2013-08 EN ISO 10121-2:2013 (E) 4 1 ScopeThis part of ISO 10121 aims to provide an objective test method to estimate the performance of any full size g
38、as filtration device (GPACD) for general filtration regardless of media or technique used in the device. In fact, the goal of this part of ISO 10121 is to avoid relating the test data to internal parameters altogether. The benefit with this approach is that customers of GPACDs will be able to concen
39、trate on price/performance and suppliers 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 spec
40、ified. 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 i
41、nto the test apparatus, can be meaningfully judged by the test method and are intended for general ventilation applications, both residential and non residential. Nuclear and military applications are specifically excluded.2 Normative referencesThe following documents, in whole or in part, are norma
