Significance and Use

4.1?This practice identifies methods for cleaning and maintaining controlled areas and clean rooms as defined by ISO 14644-1 and ISO 14644-2. Cleaning procedures are described, and cleaning frequency for different classes of facility are given. Compliance with this practice will make it easier and more likely that the required level of facility cleanliness will be maintained. A cleaner facility also will help to protect flight hardware from contamination and should reduce the frequency for cleaning flight hardware. This practice does not discuss operation and operational procedures for cleanrooms and controlled areas. Other documents such as IEST-RP-CC026 and Practice E2352 provide recommended practices for operating cleanrooms and controlled areas.

1. Scope

1.1?This practice covers the procedures to be followed for the initial cleaning and normal maintenance of cleanrooms and controlled areas. This practice is applicable to aerospace clean areas where both particles and molecular films (NVR) must be controlled.

1.2?UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
