GOST 33-2000 PDF

Full title and description

GOST 33-2000 — "Нефтепродукты. Прозрачные и непрозрачные жидкости. Определение кинематической вязкости и расчет динамической вязкости" (English: Petroleum products — Transparent and opaque liquids — Determination of kinematic viscosity and calculation of dynamic viscosity). The standard specifies a capillary viscometer method for measuring kinematic viscosity of liquid petroleum products and shows how to calculate dynamic viscosity from measured kinematic viscosity and density.

Abstract

GOST 33-2000 sets out the laboratory procedure using calibrated glass capillary viscometers to determine the kinematic viscosity of transparent and opaque petroleum liquids and gives the formula for converting kinematic viscosity to dynamic viscosity (η = ν · ρ). It applies to a wide range of liquid petroleum products (but excludes bitumen) and defines test temperatures, sample handling, apparatus, procedure, and calculation rules.

Scope

This standard establishes a method for determining kinematic viscosity of liquid petroleum products (transparent and opaque) by measuring the flow time of a defined volume through a calibrated glass capillary viscometer under gravity, and for calculating dynamic viscosity from kinematic viscosity and density. It is intended for laboratory use on fuels, lubricants and related petroleum liquids; it does not apply to bitumen.

Key topics and requirements

• Definitions of kinematic and dynamic viscosity and the relationship η = ν · ρ.
• Apparatus: requirements for calibrated glass capillary (Ubbelohde or equivalent) viscometers, thermostatic baths, thermometers and timing devices.
• Sample conditioning and temperature control — specified test temperatures and equilibration procedures for accurate repeatability.
• Measurement procedure: filling, cleaning, timing of efflux, recommended volume/time ranges and repeat measurements.
• Calculation methods, correction for temperature, and precision/repeatability criteria.
• Safety, handling and reporting requirements for petroleum-laboratory measurements.

Typical use and users

Laboratories in petroleum refineries, fuel-testing and quality-control facilities, petrochemical R&D, lubricant manufacturers, shipping and fuel inspection services, and regulatory testing bodies use this method to verify product compliance, specify product grades and monitor production quality. Test engineers, chemists and laboratory technicians are the primary users.

FAQ

Q: What is this standard?

A: GOST 33-2000 is a Russian national standard that specifies the laboratory method for determination of kinematic viscosity of transparent and opaque petroleum liquids and the calculation of dynamic viscosity from measured kinematic viscosity and density.

Q: What does it cover?

A: It covers apparatus requirements (glass capillary viscometers), sample preparation, temperature control, measurement procedure (efflux timing), calculations and reporting for kinematic and derived dynamic viscosity. It is not intended for bitumen.

Q: Who typically uses it?

A: Petroleum and lubricant testing laboratories, refinery QC teams, standards bodies, inspection and certification agencies, and R&D labs that evaluate fluid viscosity properties.

Q: Is it current or superseded?

A: GOST 33-2000 has been superseded in practice by a later edition/ successor — GOST 33-2016 (the GOST 33 family has been updated and harmonized with later international revisions). Check local national catalogs for the currently enforced edition for regulatory or contractual use.

Q: Is it part of a series?

A: Yes — it belongs to the set of petroleum product test-method standards (GOST family) and is directly related to previous versions (e.g., GOST 33-82) and successor versions (GOST 33-2016), and is aligned historically with ISO 3104 test-method conventions.

Q: What are the key keywords?

A: Kinematic viscosity, dynamic viscosity, capillary viscometer, petroleum products, GOST 33, ISO 3104, laboratory test method.
