This standard provides methods for specifying and determining product cleanliness levels for contamination-critical products. The emphasis is on contaminants that can impact product performance. The requirements set forth in this standard are intended for use in procurement and design contracts for those items where contamination control limits for parts, components, or fluids are necessary to ensure reliability and performance. This standard provides mutually agreed-upon limits for defining significant surface cleanliness and liquid cleanliness with respect to particles and molecular residue.
