GOST 5513-86 PDF

Full title and description

GOST 5513-86 — Oil products. Methods for determination of mechanical impurities. This Soviet-era standard specifies laboratory methods and procedures for detecting and quantifying mechanical impurities (solid particulate contaminants) in petroleum products and related liquids.

Abstract

GOST 5513-86 establishes procedures to prepare samples and determine the presence and mass of mechanical impurities in various oil products. The standard defines filtration, washing, drying, weighing steps and limits of detection to ensure consistent assessment of cleanliness and quality for fuels, lubricants and other petroleum-derived liquids.

General information

• Status: National standard of the USSR, widely used in USSR and successor states; historically current as of 1986 and may be superseded or withdrawn by later national or interstate standards.
• Publication date: 1986
• Publisher: State Committee for Standards of the USSR (Gosstandart) / national standards bodies in successor states typically reference original GOST documents
• ICS / categories: 75.160 (Petroleum products and related technologies) / Quality control and test methods for fuels and lubricants
• Edition / version: Original 1986 edition (designation GOST 5513-86)
• Number of pages: Typically a short technical standard (commonly 6–12 pages); exact page count may vary by publication format

Scope

This standard applies to petroleum products and oil-derived liquids where the presence of mechanical impurities (solid particles, dust, rust, sand, etc.) affects performance, reliability and safety. It covers sample preparation, filtration and gravimetric determination of mechanical impurities to quantify contamination levels for quality control, acceptance testing and investigation of contamination-related failures.

Key topics and requirements

• Definitions and terms relating to mechanical impurities in oil products.
• Requirements for sample collection, handling and storage to avoid contamination or loss of particles.
• Filtration procedures using specified filter materials and pore sizes appropriate to the product and required sensitivity.
• Washing, drying and conditioning of filters and residues to constant mass for gravimetric determination.
• Calculation methods to express mechanical impurities as mass per unit volume (e.g., mg/m³ or mg/kg) and reporting formats.
• Quality assurance measures: calibration, blank tests, repeatability and permissible errors.
• Safety and environmental precautions when handling oil samples and solvents used for washing filters.

Typical use and users

Used by petroleum laboratories, refineries, fuel and lubricant manufacturers, quality control and inspection bodies, maintenance workshops and research institutions. Typical users include laboratory analysts performing acceptance testing, plant quality engineers monitoring contamination control, and forensic investigators examining contamination-related equipment failures.

Related standards

Standards for related test methods and quality parameters for fuels and lubricants, including other GOSTs and international equivalents covering filtration tests, particle counting, cleanliness classes, water content, sediment and corrosion tests. National or interstate standards may supersede or complement GOST 5513-86 for modern analytical techniques (for example, standards for automatic particle counters, ISO methods for cleanliness, and newer national GOST/EN/ISO test methods).
