ASTM D8179-18 (2024) PDF

Full title and description

ASTM D8179-18 (reapproved 2024) — Standard Guide for Characterizing Detergents for the Cleaning of Clinically‑used Medical Devices. This short guide identifies consensus test methods (ASTM and other standards) and characterisation approaches that manufacturers and laboratories can use to describe the key physical, chemical and performance characteristics of detergents intended for cleaning clinically‑used medical devices.

Abstract

This guide recognises that detergents are critical to effective cleaning of medical devices but that few consensus methods exist to describe detergent characteristics for this application. D8179-18 lists applicable test methods and measurement approaches (surface tension, foaming, corrosivity/compatibility, residues, cleaning efficacy test methods, etc.), and points users to related ASTM and other consensus standards which can be used to characterize detergents. The guide is intentionally concise and acts as a roadmap to appropriate test methods rather than defining new performance limits.

Scope

D8179 provides guidance for characterizing detergents intended for cleaning clinically‑used medical devices. It identifies existing consensus test methods and measurement approaches that are relevant to detergent characterisation (for example, methods for surface tension, foaming/foam stability, corrosion/compatibility testing, residue measurement and laboratory cleaning efficacy tests), and distinguishes exclusions such as detergents formulated exclusively for manufacturing‑process residue removal or providing disinfection as a primary function. The guide is intended to help detergent manufacturers and device makers choose appropriate methods and to identify gaps where new standardized tests may be needed.

Key topics and requirements

• Identification of consensus test methods useful for detergent characterisation (surface tension, foaming, wetting, emulsification, detergency tests).
• Guidance on corrosion/compatibility evaluation of detergents with common medical‑device materials (metals, polymers) and reference to immersion/corrosion guides.
• Reference to laboratory cleaning efficacy tests and test soils used for validation of cleaning methods for reusable medical devices.
• Notes on exclusions — not intended for detergents that are primarily disinfectants or for manufacturing‑process residue removal.
• Encouragement to use SI units and to follow applicable safety, health and regulatory requirements when applying tests.

Typical use and users

Primary users are detergent manufacturers, medical device manufacturers, contract test laboratories, hospital sterilisation/reprocessing teams involved in product development and validation, and standards bodies. Typical uses include selecting test methods to characterise a detergent formulation, documenting detergent properties for device cleaning validation, and identifying testing gaps when developing new detergents or cleaning processes.

Related standards

D8179 cross‑references and points users toward other ASTM and industry documents commonly used in this area, for example ASTM F3208 (selecting test soils for validation of cleaning methods), F3293 (application of test soils), ASTM D7225 (blood cleaning efficiency / washer‑disinfectors), ASTM D459 (detergent terminology) and corrosion/immersion guidance such as G31; it also refers to AAMI guidance documents for reprocessing and cleaning validation (AAMI TIR12, TIR30). Users should consult those documents for specific test procedures and acceptance criteria.

FAQ

Q: What is this standard?

A: ASTM D8179-18 is a concise guide that identifies consensus test methods and characterisation approaches for detergents intended to clean clinically‑used medical devices; it does not itself set numeric performance limits but points to appropriate test methods.

Q: What does it cover?

A: It covers selection of applicable test methods and measurement topics for detergent characterisation (physico‑chemical properties, material compatibility/corrosivity, laboratory cleaning efficacy, residue measurement) and lists exclusions such as primary disinfectant products and manufacturing‑process residue detergents.

Q: Who typically uses it?

A: Detergent formulators, medical device manufacturers, test laboratories, and clinical/hospital reprocessing personnel who need to select or document test methods for cleaning validation and detergent characterisation.

Q: Is it current or superseded?

A: The original edition was approved September 1, 2018. Several standards catalogues list the guide as reapproved and republished effective January 1, 2024 (designation shown as D8179‑18(2024) or D8179‑18R24). Some registry entries vary (a small number of sources have flagged different status historically), so for purchase or the definitive status check consult ASTM International’s document summary or customer service.

Q: Is it part of a series?

A: It is a standalone guide within ASTM Committee D12 (Soaps and Other Detergents) outputs and is directly related by subject to other ASTM guides and test methods used for cleaning validation (for example F3208, F3293, D7225, G31, etc.). It is intended to be used in conjunction with those more detailed test methods.

Q: What are the key keywords?

A: detergent, cleaning, medical device, cleaning validation, test soil, foaming, surface tension, residues, corrosion compatibility.
