About This Item
ASTM E979 is a technical standard focused on evaluating antimicrobial agents used as preservatives in invert emulsion and other water-containing hydraulic fluids. It provides a structured way to assess preservative performance in fluid systems where microbial control can affect product stability and service life. For buyers, labs, and fluid formulators, this ASTM standard supports more consistent testing and comparison of antimicrobial treatments in hydraulic fluid applications.
What is ASTM E979?
ASTM E979 is a practice for evaluating antimicrobial agents intended to preserve invert emulsion and other water-containing hydraulic fluids. Its main value is in helping users assess whether a preservative performs as intended in fluid formulations that can be vulnerable to microbial growth. By offering a common evaluation framework, the standard helps align testing methods, product screening, and technical review when comparing preservative options for these fluid systems.
Where is ASTM E979 used?
This standard is commonly used in technical and quality control settings involving hydraulic fluids that contain water or are formulated as invert emulsions. It may be relevant for fluid manufacturers, additive suppliers, and test laboratories working on preservative selection or product evaluation. ASTM E979 is especially useful when a formulation must be checked for resistance to microbial-related degradation during development, procurement review, or routine performance assessment.
Why is ASTM E979 important?
ASTM E979 matters because preservative performance can influence the reliability and storage stability of water-containing hydraulic fluids. A defined evaluation practice helps reduce uncertainty when comparing antimicrobial agents, supporting more consistent product decisions and quality control. It can also aid compliance efforts and procurement specifications by giving stakeholders a recognized technical reference for testing preservative effectiveness in these fluid types.
