Full title and description

St ASTM D2270-10(2016) — Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 °C and 100 °C (Russian language / русская версия available). This practice defines the procedures (table look‑ups and equations) for calculating the Viscosity Index (VI) of petroleum products and related lubricants from measured kinematic viscosities at 40 °C and 100 °C; includes Procedure A (VI ≤ 100) and Procedure B (VI ≥ 100).

Abstract

This standard provides the calculation procedures and reference tables/equations used to convert kinematic viscosity measurements at 40 °C and 100 °C into a single-number Viscosity Index (VI) that expresses temperature dependence of viscosity for lubricating oils and related petroleum products. The practice states applicability limits (not for fluids with kinematic viscosity < 2.0 mm²/s at 100 °C) and references accepted kinematic viscosity test methods.

• Publication date: Original designation D2270-10 published 01 Oct 2010; reissued as D2270-10(2016) (2016 reapproval/issue). (See note on later 2024 revision.)
• Publisher: ASTM International (Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants — subcommittee D02.07).
• ICS / categories: 17.060 — Measurement of volume, mass, density, viscosity (also indexed under petroleum/lubricants classifications).
• Edition / version: D2270-10 (2016) — designation indicates the 2010 practice with a 2016 reissue notation.
• Number of pages: 5–6 pages in the published pamphlet (typical electronic/pdf length 5–6 pages depending on publisher formatting).

Scope

The practice covers calculation procedures to obtain the Viscosity Index (VI) of petroleum products and related lubricants from kinematic viscosity values measured at 40 °C and 100 °C, including: table lookups and formulae for products with kinematic viscosity between ~2 and 70 mm²/s (cSt) at 100 °C and equations for higher viscosities; procedures A and B for products below and above VI = 100; and limitations/exceptions (e.g., not intended for products with kinematic viscosity < 2.0 mm²/s at 100 °C). The standard also references accepted kinematic viscosity test methods (D445, D7042, IP 71, ISO 3104).

Key topics and requirements

• Definition and significance of Viscosity Index (VI) as a measure of temperature dependence of kinematic viscosity.
• Procedure A — calculation/table method for VI ≤ 100 (use of tabulated reference values).
• Procedure B — equations for calculating VI when VI ≥ 100 (mathematical formulation provided).
• Applicability limits (kinematic viscosity at 100 °C ≥ 2.0 mm²/s; table range ~2–70 mm²/s; equations for higher viscosities).
• Reference to accepted viscosity measurement methods (ASTM D445, D7042; IP 71; ISO 3104) and guidance on consistency of test-method results when calculating VI.
• Notes on units (SI units standard; 1 mm²/s = 1 cSt) and user responsibility for safety and regulatory considerations.

Typical use and users

Used by lubricant and base‑oil test laboratories, product development engineers, quality control personnel, formulators, suppliers, and standards/lab accreditation bodies to characterize temperature sensitivity of lubricants and compare fluids by a single index. Common in petroleum and lubricant specifications, supplier technical data sheets, and OEM lubricant requirements.

The practice is often used alongside other D02 committee methods and is included in lubricant testing suites.

Q: What does it cover?

A: It covers calculation methods (Procedure A for VI ≤ 100 and Procedure B for VI ≥ 100), applicability limits (not for kinematic viscosity < 2.0 mm²/s at 100 °C), reference measurement methods, and guidance on units and interpretation.

Q: Who typically uses it?

A: Test laboratories, lubricant formulators, QC/QA teams, suppliers, OEM engineers, and standards/ accreditation personnel who need a standardized VI value for specification, comparison, or reporting.

Q: Is it current or superseded?

A: The D2270-10(2016) text has been superseded by a later revision — ASTM D2270-24 (published 1 May 2024). For current, normative practice use D2270-24; D2270-10(2016) may still be cited historically or for legacy data but is not the latest revision.
