The responsible German body involved in its preparation was the DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical E

7、ngineering), Working Committee NA 060-09-21 AA Luftfilter of Section Allgemeine Lufttechnik. Representatives of manufacturers and users of air filters, and of research and testing institutes contributed to this standard. This standard contains specifications meeting the essential requirements set ou

8、t in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. The International Standard

Where the International Standards and publications referred to are not also DIN ISO Standards with the same number, there are no national standards

10、available. In addition to the legal units of measurement, this standard also uses the unit “ft” (“feet”). It should 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. The indication of

11、 this unit solely serves to facilitate the communication with those countries where this unit is used (import-export business). Conversion Non-SI unit SI unit Conversion ft m 1 ft = 0,304 8 m Amendments This standard differs from DIN EN ISO 10121-1:2014-10 as follows: a) 5.3, Table 1: The text “give

12、n in Annex D for 5.4 or user selected in 5.5” refers to air flow rate, face velocity and residence time. Thus, the line “residence time” has been connected accordingly. In the last line of the penultimate column (empty cell) “n.a.” has been added. b) 7.2.2: After the first sentence, the formula in t

13、he second indent has been corrected to read “tDC(tEND tVC).” DIN EN ISO 10121-1:2015-10 3 c) Table A.3: (German version only) In the 2nd column, 7th line, “Monitor CU, CD, TU, TD, RHU, RHD, P and Q, every 5 data points (jeweils bei fnf Datenpunkten), recorded for empty test stand” has been corrected

14、 to read “Monitor CU, CD, TU, TD, RHU, RHD, P and Q, every min during 5 data points recorded for empty test stand”.

This demand can be expecte

31、d 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 phrased more technically: gas-phase air cleaning devices (GPACD). The performance of devices using adsor

32、ption for gas removal relies to a large extent on the performance of a solid gas-phase air cleaning media (GPACM) incorporated in the device. Still applications, device performance and media performance are often poorly understood by the user and supplier of such media and devices. Media tests may a

33、lso 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 in the real applications. Such tests are however

34、 not included in the scope of this part of ISO 10121. This part of 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 ventilation in Japan1by JIS, A

35、utomotive filters by ISO, in-duct sorptive media gas-phase air-cleaning devices by ASHRAE2and for adsorptive media by ASHRAE3and ASTM.5No international standard for general filtration exists today.This part of ISO 10121 provides methods, test equipment, data interpretation and reporting for three di

36、fferent types of gas-phase air cleaning media (GPACM) intended for use in gas-phase air cleaning devices (GPACD) for 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 g

37、ives a list of possible test gases, generation sources and suggests proper analysis equipment for common test gases Annex C describes the design of the test stand except the normative sample holder. Annex D describes the normative test setup and normative section of the test stand for the three diff

38、erent media configurations.A general introduction to molecular filtration and molecular filtration testing can be found in the scientific literature.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 gen

39、eral ventilation. It consists of two parts: 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 loo

40、se fill media properties. 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.4DIN EN ISO 10121-1:2015-10 EN ISO 10121-1:2014 (E) 1 ScopeThis part of ISO 10121

41、 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 appl

42、ications. This part of ISO 10121 is specifically intended for challenge testing and not for general material evaluation or pore system characterization. The three different types of GPACM identified in this part of ISO 10121 are GPACM-LF (particles of different shape and size intended for e.g. Loose

43、 Fill applications), GPACM-FL (FLat sheet fabric intended for e.g. flat one layer, pleated or bag type devices) and GPACM-TS (three dimensional structures that are many times thicker than flat sheet and e.g. used as finished elements in a device). The tests are conducted in an air stream and the GPA

44、CM 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 performan

45、ce 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.To ensure objectivi

46、ty for test equipment suppliers, no specific design of the test apparatus is defined: an example is illustrated in Annex C (informative). Instead normative demands for media sample holder design, apparatus properties and validation tests are specified.2 Normative referencesThe following documents, i
