GOST 14202-69 PDF

Full title and description

GOST 14202-69 — Pipelines of industrial enterprises. Identification colouring, warning (safety) signs and marking plates (Russian: Трубопроводы промышленных предприятий. Опознавательная окраска, предупреждающие знаки и маркировочные щитки). The standard specifies visual identification (colour coding), warning signs and marking plates intended to identify the contents of process pipelines, their fittings and associated markings inside buildings and on outdoor installations at industrial sites.

Abstract

This Soviet-era GOST establishes a system of colours, marking plates and warning signs for industrial pipelines to enable rapid recognition of transported media and to improve operational safety and maintenance. It defines classification groups for transported substances, colour combinations, placement rules for labels and plates, and exceptions (for example, it does not apply to electrical conduits). The standard was introduced following a Committee of Standards decision of 1969.

General information

• Status: Withdrawn / superseded in national practice (historical Soviet GOST; often cited in later documents and guidance).
• Publication date: Issued 1969 (GOST number year), published/entered into use around 1970–1971 (official introduction period noted from 01.01.1971).
• Publisher: Committee of Standards, Measures and Measuring Devices attached to the Council of Ministers of the USSR (Gosstandart / Soviet standards authorities).
• ICS / categories: Pipelines and their components; industrial pipeline marking and safety signage (ICS classification commonly shown as 23.040 in related catalogs).
• Edition / version: Original GOST 14202-69 (1969). Amendments and corrections were later recorded in some reprints; modern collections may show editorial notices.
• Number of pages: Typically shown as 17–18 pages depending on publisher/reprint.

Scope

Applies to process pipelines of industrial enterprises (including connecting parts, fittings and insulated sections) located inside buildings, outdoors, on overpasses and in underground channels. The standard's purpose is to enable quick determination of pipeline contents to support production management, maintenance and occupational safety; it explicitly excludes identification of electrical conduits and wiring. It sets requirements for where and how colour bands, warning signs and marking plates are placed and how different media are grouped for identification.

Key topics and requirements

• Classification of transported media into defined groups for the purpose of consistent colour coding and marking.
• Standard colours and colour combinations for main line identification (bands, stripes, background/foreground combinations).
• Design, dimensions and placement rules for marking plates and warning signs on pipelines and fittings.
• Rules for marking at valves, branches, pumps and where pipelines pass through walls, floors, or public areas.
• Exemptions and limits — the standard does not apply to electrical conduits and provides guidance on special cases (e.g., insulated lines, small-diameter lines, or hazardous media requiring supplementary signs).

Typical use and users

Used by plant designers, process and mechanical engineers, health & safety professionals, maintenance teams and site inspectors at chemical, petrochemical, power, water treatment and other industrial facilities. Although an older Soviet standard, it is frequently referenced for historical practice, transitional markings and as a basis for national or company-specific pipeline identification schemes.

Related standards

Referenced and related documents include later national GOST/R standards and sector-specific regulations covering pipeline construction, operation and safety (examples of related standards and rules that reference or complement this subject matter include various GOSTs on safety signs and industrial pipelines and later technical regulations and industry codes such as pipeline operation and fire/safety regulations). Practitioners commonly cross-reference this GOST with subsequent standards on pipeline materials, safety signage and technological pipeline requirements.

FAQ

Q: What is this standard?

A: GOST 14202-69 is a Soviet standard that defines colour coding, warning signs and marking plates for industrial process pipelines to identify their contents and improve operational safety.

Q: What does it cover?

A: It covers visual identification of pipelines (colour bands, plates, signs), rules for placement on pipes, fittings and insulation, classification groups for transported media, and special-case exemptions (it does not cover electrical conduits).

Q: Who typically uses it?

A: Plant engineers, safety officers, maintenance personnel, designers and inspectors in industrial enterprises; it is also used as a reference in regulatory documents and technical guidance.

Q: Is it current or superseded?

A: The original GOST 14202-69 is treated as a historical / withdrawn standard in many catalogs and has been superseded in practice by later national standards, regulations and industry-specific rules; however, it remains referenced in some guidance and archival documentation. Catalog entries list it as withdrawn or out of active status.

Q: Is it part of a series?

A: Yes — it belongs to the body of GOST standards related to pipelines, pipeline components and industrial safety signage; it is one element in the broader set of Soviet/Russian standards governing marking, safety signs and pipeline engineering.
