Standard Practice for Determination of Soluble Residual Contamination by Soxhlet Extraction
N G120
Annotation
This practice describes a procedure for the determination of residual contamination in materials to be used within or in contact with hardware requiring a high level of cleanliness, such as components for oxygen service, by Soxhlet extraction.
This practice may be used for extracting nonvolatile and semivolatile residues from solids such as new and used gloves, new and used wipers, contaminated test specimens or control coupons, small piece parts (metallic or nonmetallic), etc. When used with proposed consumable cleaning materials (wipers, gloves, etc.), this practice may be used to determine the potential of the proposed solvent to extract contaminants (plasticizers, residual detergents, brighteners, etc.) from the cleaning material and deposit them on the surface being cleaned.
This practice is not suitable for the evaluation of particulate contamination.
The values stated in SI units are standard.
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 and health practices and determine the applicability of regulatory limitations prior to use.
