ASTM G136-03 (2023)e1 PDF

Full title and description

ASTM G136-03(2023)e1 — Standard Practice for Determination of Soluble Residual Contaminants in Materials by Ultrasonic Extraction. This practice describes procedures to extract and quantify soluble and semivolatile residues from materials (for example gloves, wipes, soft goods and component materials) using ultrasonic extraction and subsequent analytical evaluation of nonvolatile residue or other appropriate analytes.

Abstract

This practice provides a reproducible ultrasonic-extraction technique for recovering soluble residual contaminants from materials and cleaning aids, and guidance on analytical approaches (gravimetric nonvolatile residue, chromatography, total carbon analysis, etc.) to evaluate extractables that could contaminate sensitive systems such as oxygen systems or precision surfaces. It is intended for extractable/soluble contamination assessment and is not suitable for particulate contamination testing.

Scope

The practice may be used to extract nonvolatile and semivolatile residues from materials such as new and used gloves, wipes, soft goods, and similar components to determine extractable contaminants that could be transferred during cleaning or service, especially for systems requiring high cleanliness (e.g., oxygen systems). It explicitly excludes evaluation of particulate contamination and provides SI unit values as standard. The practice also identifies suitable solvents, sample preparation, ultrasonic bath treatment, and subsequent analytical evaluation pathways.

Key topics and requirements

• Purpose and intended use: assessment of soluble/extractable contaminants from materials and cleaning aids.
• Sample preparation and placement in an ultrasonic extraction bath with controlled temperature and time.
• Approved/exemplary solvents: tetrachloroethylene (perchloroethylene), trichloroethylene, methylene chloride, and selected perfluorinated carbon fluids (with safety considerations noted).
• Analytical endpoints: nonvolatile residue (NVR) by gravimetric methods and instrumental techniques such as gas chromatography, GC–MS, and total carbon analysis where referenced (e.g., Test Methods E1235, F324, F331 and related methods).
• Limits and exclusions: not intended for particulate contamination testing; users must establish appropriate safety, health, and environmental practices for solvent use.

Typical use and users

Used by contamination-control laboratories, quality and R&D groups in aerospace, oxygen-system manufacturers, medical device and precision-engineering suppliers, and third‑party testing labs to evaluate extractable residues from cleaning materials and component soft goods. Typical applications include pre‑use qualification of wipes/gloves, verification of cleaning processes, and material screening for sensitive fluid or oxygen environments.

Related standards

This practice references and is commonly used alongside related ASTM methods and guides for contamination assessment and residue analysis, including ASTM Test Methods E1235, F324, F331 (nonvolatile residue and solvent-extract methods), and other practices for cleaning and contamination (for example, ASTM G131 for ultrasonic cleaning and ASTM G144 for total carbon analysis relationships). Users should consult the referenced methods for analytical details.
