23、l Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been es

24、tablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardi

25、zation. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for vot

26、ing. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all suc

27、h patent rights. ISO 14644-5 was prepared by Technical Committee ISO/TC 209, Cleanrooms and associated controlled environments. ISO 14644 consists of the following parts, under the general title Cleanrooms and associated controlled environments: Part 1: Classification of air cleanliness Part 2: Spec

28、ifications for testing and monitoring to prove continued compliance with ISO 14644-1 Part 3: Test methods Part 4: Design, construction and start-up Part 5: Operations Part 7: Separative devices (clean air hoods, gloveboxes, isolators and mini-environments) Part 8: Classification of airborne molecula

29、r contamination The following part is under preparation: Part 6: Terms and definitions ENISO146445:2004 vIntroduction Industries and organizations of all kinds utilize cleanrooms. Operational procedures have a profound effect on the cleanliness levels achieved during the operation of the cleanroom a

30、nd equipment. Consistent quality is cleanliness dependent. Operational cleanliness can only be attained and maintained through a deliberate programme established to specify, measure and enforce defined operational procedures. Regulatory agencies that have authority over processes and products produc

31、ed in the cleanroom may require additional procedures and measures of cleanliness not covered in this general operating standard. This part of ISO 14644 addresses normative and informative operational requirements related to: a) providing a system that defines policies and operational procedures; b)

32、 clothing used to isolate human-generated contamination from the cleanroom environment; c) training of personnel inside the cleanroom and monitoring their compliance to specified procedures and disciplines; d) transfer, installation and maintenance of stationary equipment (selection criteria is not

33、discussed); e) selection and use of materials and portable equipment in the cleanroom; f) maintaining the cleanliness of the cleanroom through systematic cleaning and monitoring procedures.

34、rt 5: Operations 1 Scope This part of ISO 14644 specifies basic requirements for cleanroom operations. It is intended for those planning to use and operate a cleanroom. Aspects of safety that have no direct bearing on contamination control are not considered in this part of ISO 14644 and national an

35、d local safety regulations must be observed. This document considers all classes of cleanrooms used to produce all types of products. Therefore, it is broad in application and does not address specific requirements for individual industries. Methods and programmes for routine monitoring within clean

36、rooms are not covered in detail in this part of ISO 14644 but reference is made to ISO 14644-2 and ISO 14644-3 for monitoring particles and ISO 14698-1 and ISO 14698-2 for monitoring micro-organisms. 2 Normative references The following referenced documents are indispensable for the application of t
