Full title and description

O’z DSt 3031:2015 — "Automotive gasolines. Technical specifications." Specifies technical requirements, grades and quality-control/test methods for automotive (spark‑ignition) gasoline intended for use in road vehicles and other engines designed for automotive gasoline.

Abstract

This national standard (Uzbekistan) defines composition and quality limits (octane ratings, volatility, density, sulfur and other contaminant limits, permitted additives and related test methods) for commercial automotive gasoline grades (examples: AI‑80, AI‑92, AI‑95) and establishes sampling and conformity assessment provisions used by producers, testing laboratories and regulators. It replaces earlier technical specifications used locally.

General information

• Status: Active (national standard in force, referenced by industry suppliers).
• Publication date: 2015.
• Publisher: Uzbek national standardization authority (Uzbek Agency for Standardization, Metrology and Certification — commonly referenced as Uzstandart).
• ICS / categories: 75.160.20 — Liquid fuels (petroleum products / automotive fuels).
• Edition / version: 2015 edition (O’z DSt 3031:2015).
• Number of pages: 24 pages (electronic/pdf editions reported).

Scope

Applies to automotive (spark‑ignition) gasolines produced or sold within Uzbekistan that must meet national technical requirements. The standard covers product grades, required physico‑chemical parameters, limits on contaminants (e.g., lead, sulfur), permitted additives, sampling procedures and key test methods for verifying conformity. It is intended for use by refiners, fuel marketers, test laboratories and regulatory bodies.

Key topics and requirements

• Definition of commercial gasoline grades and designation (e.g., AI‑80, AI‑92, AI‑95).
• Mandatory physico‑chemical parameters: octane rating (RON/MON or equivalent), volatility/fractional composition, density, vapour pressure, distillation characteristics.
• Limits on sulfur content, lead (for unleaded requirements), aromatics and other regulated contaminants.
• Specifications for permitted additives and dosage limits (detergents, anti‑corrosion additives, oxygenates where applicable).
• Sampling, test methods and conformity assessment procedures (laboratory test methods and tolerances for acceptance/rejection).
• Labelling, storage and handling notes relevant to maintaining fuel quality in distribution and retail.

Typical use and users

Primary users include petroleum refineries, fuel blending and distribution companies, independent fuel terminals, accredited testing laboratories, vehicle fleet operators, and national/regional regulators enforcing fuel quality and environmental limits. Industry product pages and refinery catalogs in Uzbekistan reference O’z DSt 3031:2015 as the normative document for marketed gasoline grades.

Related standards

Commonly referenced companion documents include regional/interstate GOST standards and national technical regulations for fuels (for example, related GOST documents on motor and aviation gasoline and the national technical regulation Uz TR references used in Uzbekistan). The standard supersedes/updates earlier local technical specifications (listed in the document metadata).
