Provides design requirements and guidance for the construction of pharmaceutical isolators, recommendations for the environment in which they are to be used, performance requirements and guidance on their installation and use.

This Standard gives design requirements and guidance for the construction of pharmaceutical isolators, recommendations for the environment in which they are to be used, performance requirements and guidance relating to their installation and use. It does not refer to flexible film or hybrid isolators or to devices intended to be used for handling of pathogenic organisms.NOTE: Appendix A provides guidance on information that should be discussed between purchaser and supplier.
