The work of preparing International Standards is norm
20、ally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in t
21、he work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 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
22、 International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. 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
23、 of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14644-3 was prepared by Technical Committee ISO/TC 209, Cleanrooms and associated controlled environements. ISO 14644 consists of the following
24、parts, under the general title Cleanrooms and associated controlled environments: Part 1: Classification of air cleanliness Part 2: Specifications 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: Operatio
25、ns Part 7: Separative devices (clean air hoods, gloveboxes, isolators and mini-environments) Part 8: Classification of airborne molecular contamination The following part is under preparation: Part 6: Vocabulary v Introduction Cleanrooms and associated controlled environments provide for the control
26、 of airborne contamination to levels appropriate for accomplishing contamination-sensitive activities. Products and processes that benefit from the control of airborne contamination include those in such industries as aerospace, microelectronics, pharmaceuticals, medical devices, healthcare and food
27、. This part of ISO 14644 sets out test methods that may be used for the purpose of characterizing a cleanroom as described and specified in other parts of ISO 14644. NOTE Not all cleanroom parameter test procedures are shown in this part of ISO 14644. The procedures and apparatus to characterize oth
28、er parameters, of concern in cleanrooms and clean zones used for specific products or processes, are discussed elsewhere in other documents prepared by ISO/TC 209 for example, procedures for control and measurement of viable materials (ISO 14698), testing cleanroom functionality (ISO 14644-4), and t
29、esting of separative devices (ISO 14644-7). In addition, other standards can be considered to be applicable. Statements in this part of ISO 14644 reference the standards of ASTM, CEN, DIN, IEST, JACA, JIS and SEMI. EN ISO 14644-3:2005blank1 Cleanrooms and associated controlled environments Part 3: T
30、est methods WARNING The use of this part of ISO 14644 may involve hazardous materials, operations and equipment. This part of ISO 14644 does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this part of ISO 14644 to establish appropri
31、ate safety and health practices and to determine the applicability of regulatory limitations prior to use. 1 Scope This part of ISO 14644 specifies test methods for designated classification of airborne particulate cleanliness and for characterizing the performance of cleanrooms and clean zones. Per
32、formance tests are specified for two types of cleanrooms and clean zones: those with unidirectional flow and those with non-unidirectional flow, in three possible occupancy states: as-built, at-rest and operational. The test methods recommend test apparatus and test procedures for determining perfor
33、mance parameters. Where the test method is affected by the type of cleanroom or clean zone, alternative procedures are suggested. For some of the tests, several different methods and apparatus are recommended to accommodate different end-use considerations. Alternative methods not included in this p
34、art of ISO 14644 may be used if based on agreement between customer and supplier. Alternative methods do not necessarily provide equivalent measurements. This part of ISO 14644 is not applicable to the measurement of products or of processes in cleanrooms or separative devices. 2 Normative reference

38、h the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation and retention of particles inside the room, and in which other relevant parameters, e.g. temperature, humidity and pressure, are controlled as necessary ISO
39、 14644-1:1999, 2.1.1 3.1.2 clean zone dedicated space in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation and retention of particles inside the zone, and in which other relevant parameters, e.g. temper
40、ature, humidity and pressure, are controlled as necessary NOTE This zone may be open or enclosed, and may or may not be located within a cleanroom. ISO 14644-1:1999, 2.1.2 3.1.3 installation cleanroom or one or more clean zones, together with all associated structures, air-treatment systems, service
41、s, and utilities ISO 14644-1:1999, 2.1.3 3.1.4 separative device equipment utilizing constructional and dynamic means to create assured levels of separation between the inside and outside of a defined volume NOTE Some industry-specific examples of separative devices are clean air hoods, containment
42、enclosures, glove boxes, isolators and mini-environments. 3.2 Airborne particle measurement 3.2.1 aerosol generator instrument capable of generating particulate matter having appropriate size range (e.g. 0,05 m to 2 m) at a constant concentration, which may be produced by thermal, hydraulic, pneumat
43、ic, acoustic or electrostatic means 3.2.2 airborne particle solid or liquid object suspended in air, viable or non-viable, sized (for the purpose of this part of ISO 14644) between 1 nm and 100 m NOTE For classification purposes, refer to ISO 14644-1:1999, 2.2.1. 3.2.3 count median particle diameter
44、 CMD median particle diameter based on the number of particles NOTE For the count median, one half of the particle number is contributed by the particles with a size smaller than the count median size, and one half by particles larger than the count median size.

45、cle particle with an equivalent diameter greater than 5 m ISO 14644-1:1999, 2.2.6 3.2.5 M descriptor measured or specified concentration of macroparticles per cubic metre of air, expressed in terms of the equivalent diameter that is characteristic of the measurement method used NOTE The M descriptor
46、 may be regarded as an upper limit for the averages at sampling locations (or as an upper confidence limit, depending upon the number of sampling locations used to characterize the cleanroom or clean zone). M descriptors cannot be used to define airborne particulate cleanliness classes, but they may
47、 be quoted independently or in conjunction with airborne particulate cleanliness classes. ISO 14644-1:1999, 2.3.2 3.2.6 mass median particle diameter MMD median particle diameter based on the particle mass NOTE For the mass median, one half of mass of all particles is contributed by particles with a
