Standard Practice for Cleaning Methods and Cleanliness Levels for Material and Equipment Used in Oxygen-Enriched Environments

1.1 This practice covers the selection of methods and apparatus for the cleaning of materials and equipment intended for service in oxygen-enriched environments. Contamination problems encountered in the use of enriched air, mixtures of oxygen with other gases, or any other oxidizing gas may be solved by the same cleaning procedures applicable to most metallic and nonmetallic materials and equipment. Cleaning examples for some specific materials, components, and equipment, and the cleaning methods for particular applications, are described in detail in the appendix.

1.2 This guide does not include levels of cleanliness necessary for various applications and materials. These sections are currently under development and will be included in a future revision.

1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Federal, state and local safety and disposal regulations concerning the particular hazardous materials, reagents, operations and equipment being used should be reviewed by the user. The user is encouraged to obtain the Material Safety Data Sheets (MSDS) from the manufacturer for any material incorporated into a cleaning process. Specific cautions are given in Section 8.
