GOST IEC 60079-10-1-2013 PDF

Full title and description

GOST IEC 60079-10-1-2013 — "Explosive atmospheres. Part 10-1. Classification of areas. Explosive gas atmospheres". This GOST is the Russian adoption of the IEC/EN technical document that specifies procedures, principles and definitions for classifying areas where flammable gases or vapours may form explosive atmospheres, to support selection and installation of equipment and precautions in hazardous areas.

Abstract

This standard gives definitions, general principles and practical procedures for the classification of hazardous areas on account of explosive gas atmospheres (zones such as 0, 1, 2). It describes how to identify sources and release characteristics, how ventilation and dispersion affect zone boundaries, and provides methods (including nomograms, calculation procedures and guidance) to determine the extent and duration of hazardous zones so that appropriate protective measures and equipment selection can be applied.

General information

• Status: Withdrawn / replaced — the GOST edition IEC 60079-10-1-2013 has been superseded by the later national adoption GOST 31610.10-1-2022 (which aligns with newer IEC revisions).
• Publication date: Designation year 2013 (GOST IEC 60079-10-1-2013); Russian catalogue entries show implementation/publication records from mid‑2015 for this adoption (sources vary by database).
• Publisher: Published/issued in Russian standards catalogues (commonly listed under Interstandard / Russian standards publishing channels for GOST adoptions).
• ICS / categories: 29.260.20 (Electrical engineering — Electrical equipment for explosive atmospheres / hazardous-area equipment).
• Edition / version: GOST adoption of IEC 60079-10-1, designated with year 2013 (commonly cited as "GOST IEC 60079-10-1-2013").
• Number of pages: commonly listed around 60–61 pages (recorded page counts vary by distributor/format).

Scope

The document applies to the classification of areas where flammable gases, vapours or mists may occur under normal atmospheric conditions and sets out principles to determine hazardous zones for the purpose of specifying equipment and protective measures. It excludes certain specific applications (for example some mining or explosives manufacture contexts), and does not address consequences of ignition beyond where they affect area classification. The procedures cover identification of sources, release characteristics, dispersion and ventilation effects and the determination of zone extents (zone 0, zone 1, zone 2).

Key topics and requirements

• Definitions and terminology for explosive atmospheres, explosive gas atmosphere and zone classification (zone 0, 1, 2).
• Principles for identifying sources of release and assessing release characteristics (frequency, quantity, phase).
• Guidance on ventilation, dispersion and environmental factors that influence hazardous-area boundaries.
• Methods and nomograms / calculation procedures to estimate hazardous distances and zone extents for various release scenarios.
• Documentation and record‑keeping requirements for area classification studies and safety decisions.
• Interface with equipment selection rules and other parts of the IEC 60079 series (selection criteria depend on identified zone classification).

These topics follow the IEC 60079-10-1 framework and are mirrored in the GOST adoption.

Typical use and users

Used by plant and facility designers, process and safety engineers, instrumentation and electrical engineers, certification bodies, regulatory authorities and maintenance personnel for the classification of hazardous areas in oil & gas, petrochemical, chemical, pharmaceutical, and similar industries where flammable gases or vapours may be present. It informs risk assessments, layouts, ventilation design and the selection/installation of explosion-protected equipment.

FAQ

Q: What is this standard?

A: It is the Russian GOST adoption of IEC 60079-10-1, providing rules and guidance for classifying areas where explosive gas atmospheres may occur (designation: GOST IEC 60079-10-1-2013).

Q: What does it cover?

A: It covers definitions, principles and practical procedures for identifying sources of flammable gas/vapour releases, assessing release characteristics and dispersion, determining hazardous-zone boundaries (zone 0/1/2) and documenting the area-classification so appropriate equipment and protections can be selected.

Q: Who typically uses it?

A: Process, safety and electrical engineers, designers, inspection and maintenance teams, certifying bodies and regulatory authorities working in industries with potential flammable gas atmospheres (oil & gas, petrochemical, chemical, pharmaceutical, utilities, etc.).

Q: Is it current or superseded?

A: The GOST IEC 60079-10-1-2013 edition has been superseded in the Russian standards system by GOST 31610.10-1-2022 (the newer adoption aligning with later IEC revisions). Users should refer to the 2022 GOST (or the latest IEC 60079-10-1 edition) for current requirements.

Q: Is it part of a series?

A: Yes — it is one part of the IEC 60079 series covering explosive atmospheres; Part 10-1 deals with gas atmospheres, while other parts of the series cover general requirements, dusts, installation, inspection and related topics (e.g., IEC 60079-0, -10-2, -14, -17).

Q: What are the key keywords?

A: Hazardous area classification, explosive gas atmosphere, zone 0/1/2, release characteristic, ventilation, dispersion, area‑classification report, IEC 60079.
