Cleanrooms and associated controlled environments: Design, construction and start-up
BS EN ISO 14644-4 is the international standard that specifies the requirements for the design, construction and start-up of cleanrooms and associated controlled environments. Part 4 of BS EN ISO 14644 specifies the requirements for the design and construction of cleanroom installations but does not prescribe specific technological or contractual means to meet these requirements. It is intended for use by purchasers, suppliers and designers of cleanroom installations and provides a checklist of important parameters of performance. Construction guidance is provided, including requirements for start-up and qualification. Application of this International Standard is restricted to the following:

User requirements are represented by purchaser or specifier Specific processes to be accommodated in the cleanroom installation are not specified Fire and safety regulations are not considered specifically; the appropriate national and local requirements should be respected Process media and utility services are only considered with respect to their routing between and in the different zones of cleanliness Regarding initial operation and maintenance, only cleanroom construction-specific requirements are considered.

BS EN ISO 14644-4  supersedes BS 5295-2:1989 which is withdrawn. See other cleanrooms standards in the BS EN ISO 14644 series .
