2、National forewordThis British Standard is the UK implementation of EN ISO 14644-14:2016. BSI, as a member of CEN, is obliged to publish EN ISO 14644-14:2016 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted ag

3、ainst its approval as a European Standard.The UK committee is of the opinion that a lack of emphasis has been placed on the importance and value of the optional “Total emission measurement method” described in informative clause B.4. In particular, this method provides important information that can

4、 be used to determine the required supply air volume in non-unidirectional airflow cleanrooms to mitigate the airborne particle load in the room. Calculated supply air volume requirements are an essential part of BS EN ISO 14644-4:2001 and the forthcoming ISO 14644-16 standard. In addition, the UK c

5、ommittee views that the method specified in clause 6 described as “measurement of air-borne particle emissions at critical locations”, should be used with caution. High levels of particle generation from some equipment can be mitigated by the use of local exhaust ventilation to prevent an adverse ef

6、fect on the room class at critical control points due to migration of airborne particles.In light of these concerns, the UK committee refers users of this standard to the paragraph at the end of clause 4 which states, “The method described in B.4 may be used to determine the aver-age total emission

7、of equipment and provides data that may be used to determine the particle load on a cleanroom”. The UK committee advises that clause B.4 be utilised to allow the customer and supplier to select this method when it is more appropriate than the method described in clause 6. The reason for this decisio

8、n should be documented when claiming conformance with BS EN ISO 14644-14:2016.The UK participation in its preparation was entrusted to Technical Committee LBI/30, Cleanroom technology.A list of organizations represented on this committee can be obtained on request to its secretary.This publication d

36、ed environments Part 14: Assessment of suitability for use of equipment by airborne particle concentration1 ScopeThis part of ISO 14644 specifies a methodology to assess the suitability of equipment (e.g. machinery, measuring equipment, process equipment, components and tools) for use in cleanrooms

37、and associated controlled environments, with respect to airborne particle cleanliness as specified in ISO 146441. Particle sizes range from 0,1 m to equal to or larger than 5 m (given in ISO 14644-1).NOTE Where regulatory agencies impose supplementary guidelines or restrictions, appropriate adaptati

38、on of the assessment methodology can be required.The following items are not covered by this part of ISO 14644: assessment of suitability with respect to biocontamination; testing for suitability of decontamination agents and techniques; cleanability of equipment and materials; requirements on desig

39、n of equipment and selection of materials; physical properties of materials (e.g. electrostatic, thermal properties); optimizing performance of equipment for specific process applications; selection and use of statistical methods for testing; protocols and requirements for local safety regulations.2
