34、N EN ISO 14644-2:2016-05 EN ISO 14644-2:2015 (E) 4 IntroductionThis revision of ISO 14644-2 emphasizes the need to consider a monitoring strategy in addition to the initial or periodic execution of the classification of a cleanroom or clean zone in accordance with ISO 14644-1:2015, 5.1. The monitori
35、ng activity provides a continuing flow of data over time, thereby providing a more detailed view of the performance of the installation.Potential benefits gained from monitoring are faster response to adverse events and conditions, ability to develop trends from data over time, integration of data f
36、rom multiple instruments, enhanced knowledge of installation and process, which allows for more effective risk assessment, and improved control of operational costs and product losses.ISO 14644-2 specifies the requirements of a monitoring plan, based on risk assessment of the intended use. The data
37、obtained provide evidence of cleanroom or clean zone performance related to air cleanliness by particle concentration.In some circumstances, relevant regulatory agencies may impose supplementary policies, requirements or restrictions. In such situations, appropriate adaptations of the monitoring pro
38、cedures may be required. After a monitoring plan is initially established and implemented, it may be necessary to revise the plan when significant changes are made to the installation or process requirements. It is also prudent to conduct periodic reviews of a monitoring plan based on data obtained
39、and experience in use.DIN EN ISO 14644-2:2016-05 EN ISO 14644-2:2015 (E) 5 1 ScopeThis part of ISO 14644 specifies minimum requirements for a monitoring plan for cleanroom or clean zone performance related to air cleanliness by particle concentration, based upon parameters that measure or affect air
40、borne particle concentration.This part of ISO 14644 does not address condition monitoring of aspects such as vibration or general maintenance of the engineering systems. It does not provide for monitoring of particle populations that are outside the specified lower threshold particle-size range, 0,1
41、 m to 5 m. Concentrations of ultrafine particles (particles smaller than 0,1m) will be addressed in a separate standard.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
