About This Item
ASTM D7279 is the standard test method for measuring kinematic viscosity of transparent and opaque liquids by an automated Houillon viscometer. It provides a controlled approach for determining flow behavior in liquids where viscosity data is needed for evaluation, comparison, or quality control. By focusing on an automated method, the standard supports more consistent testing and helps users obtain results suited to technical specifications, product assessment, and compliance-oriented workflows.
ASTM D7279 standard overview
This ASTM standard defines a test method centered on automated Houillon viscometer measurement of kinematic viscosity. The title indicates coverage for both transparent and opaque liquids, which makes the method relevant where visual clarity is not the deciding factor in test selection. As a technical document, ASTM D7279 is used to support repeatable viscosity measurement under a defined procedure, helping laboratories and product teams compare liquid performance with greater confidence.
Where is ASTM D7279 used?
ASTM D7279 is commonly used in laboratories and quality systems that need kinematic viscosity data for liquid products and samples. It is particularly relevant where transparent or opaque liquids must be tested with an automated Houillon viscometer rather than a manual approach. Typical use includes product characterization, incoming inspection, and routine testing workflows that rely on consistent viscosity results for technical evaluation and specification checks.
Practical importance of ASTM D7279
This standard matters because viscosity is a key property in product consistency, handling, and performance assessment. ASTM D7279 helps support uniform testing practices so results are more comparable across batches, labs, and procurement requirements. For organizations that rely on viscosity data, the method can reduce ambiguity in measurement and support quality control decisions, documentation, and supplier or customer specification alignment.
