Full title and description

ASTM D7279-16 — Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids by Automated Houillon Viscometer (Russian language edition / translation indicated by "rus"). This document specifies an automated Houillon capillary-tube method for determining kinematic viscosity of both transparent and opaque liquid samples using very small sample volumes and automated instrumentation.

Abstract

This test method (designation D7279, 2016 edition) defines the procedure, apparatus, calibration, and precision requirements for measuring kinematic viscosity of a wide range of liquids — including base oils, formulated oils, diesel, biodiesel and blends, residual fuels and used lubricating oils — using an automated Houillon viscometer. The method emphasizes small sample size (typically <1 mL), rapid throughput, temperature control, and applicability to opaque as well as transparent samples. The 2016 revision clarified scope and precision; the designation D7279-16 has since been superseded by later revisions of D7279.

Scope

This test method covers the measurement of kinematic viscosity of transparent and opaque liquids using an automated Houillon viscometer in an automated mode. It is applicable to fresh and used lubricating oils and to many distillates and heavier fuels (base oils, formulated oils, diesel, biodiesel and blends, residual fuel oils and marine fuels) within the instrument’s tube and temperature ranges. Typical instrument capability for the 2016 text is a temperature range of about 20 °C to 150 °C and a practical viscosity-measurement range starting near a few mm²/s (the 2016 edition lists practical tube-dependent lower limits and an upper practical range often cited around 1500 mm²/s for certain tube constants; later revisions expanded some ranges). Precision statements in the standard apply only to the viscosity ranges and sample types identified in the precision section of the standard.

Key topics and requirements

• Principle: kinematic viscosity measurement using automated Houillon (curved-capillary) viscometer tubes with optical/electronic detection of flow events.
• Small sample volumes: typical sample requirement <1 mL per test, enabling rapid, low-waste testing.
• Temperature control and calibration: requirement for precise temperature regulation (commonly ±0.01 °C in automated systems) and use of calibrated reference fluids.
• Tube constants and range: measurement range and accuracy depend on selected Houillon tube constants; user must select appropriate tubes for the viscosity range of interest.
• Precision and bias: method includes interlaboratory-derived precision statements for specified viscosity ranges and temperatures (precision typically reported at 40 °C and 100 °C for defined sample groups).
• Applicability to opaque samples: method works for both transparent and opaque liquids since detection is based on flow/time rather than optical clarity alone.
• Sample handling and cleaning: procedure defines sample introduction, tube cleaning/solvent procedures, and precautions to avoid cross-contamination and air bubbles.
• Correlation: references and crosswalks to conventional capillary methods such as ASTM D445 (kinematic viscosity by glass capillary) and to international equivalents (ISO methods) are discussed.

Typical use and users

This standard is used by quality control and testing laboratories in petroleum, lubricant and fuel production, oil analysis laboratories monitoring in-service oils, research and development groups evaluating new formulations, and instrument manufacturers and suppliers of automated Houillon viscometers. Typical users include refinery and lubricant manufacturers, independent test houses, on‑site oil analysis facilities, and OEM labs performing routine viscosity checks and condition-monitoring programs.
