30、ent is ISO/TC 142, Cleaning equipment for air and other gases.DIN EN ISO 16170:2017-05 EN ISO 16170:2016 (E)4 IntroductionMethods for measuring the performance of high efficiency gas cleaning devices are described in a number of existing standards. These specify procedures for quality assurance foll

31、owing manufacture (e.g. ISO 29463 and EN 1822).Some other standards specify the filter medium used in such devices, how they are constructed and how they are installed within industrial facilities.Installations of high efficiency particulate filters are extensively used within nuclear and toxic mate

32、rial processing plants and laboratories to confine these materials within the facility and prevent their discharge to the environment.Radioactive and other toxic materials are confined within processing facilities inside containment zones bordered by barriers. Air and gases vented from these zones a

33、re decontaminated by passage through a series of highly efficient particulate filters before final discharge to the environment. The membrane (filter medium) of the filters acts as part of the containment barrier. In view of its perceived fragility, confirmation of its integrity is required on a per

34、iodic basis because operational safety cases depend on the knowledge that the effectiveness of these filters is maintained at all times. These periodic checks are made by the procedure(s) known as “in-situ” or “in-place” testing.The basic principles of in situ tests on installed filters are the same

35、 as for laboratory tests, such as those described in EN 1822 and ISO 29463, insofar as known quantities of a challenge aerosol are dispersed into the airstream upstream of the filter installation; the particulate contents of the unfiltered and filtered air are sampled and analysed to determine wheth

36、er the integrity of the filters has been compromised.In the case of testing a single unit (manufacturers production test or in the case of a laboratory testing on a single filter unit), the purpose is to confirm that the unit performance efficiency/penetration at Most Penetrating Particle Size (MPPS

37、) and other parameters lies within specified limits, and further, that the results are globally reproducible. To achieve this requires the use of a laboratory test rig setup with full dispersion of a challenge aerosol, prescribed geometry of the test rig, and to obtain and analyse fully representati

38、ve particulate samples both upstream and downstream of the test filter. Some ventilation systems are highly complex and it should be noted that many facilities use ventilation systems in which a high percentage of the air is recirculated.The purpose of an in situ test is to detect any adverse change

39、 in the filtration performance of the installation and to compare it with the expected efficiency or decontamination factor. Such a change might be caused by deterioration of a unit or units or a faulty sealing system and would be manifested by the appearance of a proportion of unfiltered aerosol in

40、 the effluent airstream. Testing methodologies developed in this International Standard do not cover the other requirements that relate to filters in terms of mechanical resistance, burst strength or temperature and moisture resistance.It is neither fully necessary nor useful for the results of an i

41、n situ test to replicate the results of production tests on the individual filters in the installation, nor is it necessary to confine the test aerosol size distribution to one which replicates that used in production tests.No International Standard for general in situ testing of high efficiency fil

42、ters has been produced before, explaining the needs for such an International Standard.This International Standard describes the requirements for test equipment, data interpretation and reporting for the in situ testing of HEPA and ULPA air cleaning installations designed for the removal of airborne

43、 particulate contamination in high-integrity ventilation systems.This International Standard includes specification of the test interval, aerosol type, aerosol mixing and measurement methods, i.e. the following: aerosol: solid or liquid, monodisperse or polydisperse; mixing: degree of mixing, mixing

44、 lengths, etc.;DIN EN ISO 16170:2017-05 EN ISO 16170:2016 (E)5 method: injection, detection.This International Standard proposes an outline testing philosophy to highlight the following: principle of the method; prerequisites; preparatory conditions; injected aerosol properties; qualification and se

45、lection of measuring devices; qualification of test personnel; test setup; test sequence; evaluation and reporting.DIN EN ISO 16170:2017-05 EN ISO 16170:2016 (E)6 1 ScopeThis International Standard specifies in situ test methods for high efficiency particulate air filters used to limit releases towa

46、rds the environment (e.g. from nuclear facilities or facilities with aerosol toxic or biological releases). This applies where installations of these filters are used to clean effluent air before discharge to the environment from industrial (including nuclear) installations where toxic/radioactive/b

47、iological materials are handled or processed.This International Standard excludes the application already covered by ISO 14644-3.The scope of this International Standard includes detail of two methods, either of which applies to the periodic testing of high efficiency filters which are used in deman

48、ding applications aiming at protecting the environment, such as the nuclear industry.In the case of nuclear applications, this International Standard is applicable to installations covered by ISO 17873 (applications other than nuclear reactors) and ISO 26802 (nuclear reactors).The two reference methods specified in this International Standard are not equivalent, but related to, the requirements to be addressed by the test results.
