GOST 18698-79 PDF

Full title and description

GOST 18698-79 — "Рукава резиновые напорные с текстильным каркасом. Технические условия" (Textile carcass rubber pressure hoses. Specifications). The standard defines technical requirements, dimensions, tests and marking for rubber pressure hoses with a textile carcass intended for conveying liquids, saturated steam, gases and bulk materials in different climatic zones.

Abstract

GOST 18698-79 prescribes constructional classes, permitted materials, dimensional ranges, performance requirements, test methods (including hydrostatic and dimensional tests), acceptance rules, marking, packaging, transport and storage, and user instructions for textile‑carcass rubber pressure hoses. It also lists allowable climatic versions and outlines exclusions for vehicle, welding and other special-purpose hoses.

General information

• Status: Listed in public standards catalogues as a reissued / in‑force GOST with amendments (published as a state standard of the USSR and reprinted with changes); commonly used as the normative basis for textile‑carcass pressure hoses in the CIS market.
• Publication date: Effective 01 January 1981 (approved by Gosstandart USSR 29 November 1979).
• Publisher: Approved by the State Committee for Standards (Gosstandart USSR); published by Издательство стандартов and later reprinted by standard publishers (Стандартинформ / others) in subsequent editions.
• ICS / categories: Hoses / hose assemblies — ICS classifications for related hose standards: 23.040.70 (Hoses and hose assemblies) and 83.140.40 (Hoses, rubber & plastics products).
• Edition / version: Original designation GOST 18698-79 (introduced 1981) with recorded amendments and reprints (amendments recorded in indexed bulletins: ИУС 9‑81, 2‑86, 8‑87, 1‑90; later reprints/editions noted in standards catalogues).
• Number of pages: Typical published copy: 27 pages (standard reprints/offerings list 27 pages in seller/catalogue metadata).

Scope

The standard applies to rubber pressure hoses reinforced with a textile carcass used as flexible pipelines for pressurized transport of liquids, saturated steam, gases and bulk materials across cold, temperate and tropical climatic zones. It excludes hoses for gas welding and cutting, automotive/tractor agricultural hoses and certain special‑purpose hose types specified elsewhere.

Key topics and requirements

• Classification of hoses by application (example classes: Б (I) — fuel/oil; В (II) — technical water/weak solutions; ВГ/Г — hot water / gases; П (VII) — food/foodstuffs; Ш (VIII) — abrasive plaster/sand; Пар‑1/Пар‑2 — saturated steam types).
• Dimensional and constructional parameters (internal/external diameters, wall thickness, textile carcass layers, permissible tolerances and range of nominal sizes).
• Performance requirements — rated working pressures, allowable temperature ranges by class and climatic version, resistance properties of inner and outer rubber layers (oil/fuel resistance, acid/alkaline resistance, abrasion resistance for abrasive classes).
• Required tests and acceptance rules — hydrostatic strength, dimensional checks, flexibility/low‑temperature behavior, marking and visual inspection; manufacturers’ guarantees and documentation.
• Marking, packaging, storage and transportation rules and basic user/exploitation instructions (min. lengths, storage conditions, labeling of climatic category and working pressure).

Typical use and users

Typical uses: fuel and oil transfer lines, water and chemical transfer, hot‑water and steam service, abrasive material conveying (plaster, sand), food‑grade hoses for food industry processes (where specified). Typical users: hose manufacturers and suppliers, OEMs, chemical and petrochemical plants, food and beverage plants, construction and plastering contractors, procurement/specification engineers, maintenance teams and inspection laboratories in CIS countries and global buyers sourcing GOST‑compliant hoses.

Related standards

GOST 18698-79 references and is used alongside other normative documents for materials, dimensions and testing (examples of referenced GOSTs and normative items include standards on climatic categories, corrosion and material tests such as GOST 15150 series and various product/test GOSTs cited in the referenced normative list within the standard). Implementations and related hose standards (national or ISO) should be checked when integrating with other specifications.

FAQ

Q: What is this standard?

A: GOST 18698-79 is a state technical standard (originally a USSR GOST) specifying technical conditions for rubber pressure hoses with a textile carcass (construction, classes, tests, marking, packaging and use instructions).

Q: What does it cover?

A: It covers classification by service (fuel, water, gases, food, abrasive media, steam), dimensional and construction requirements, performance and test methods, acceptance rules, marking/packaging/transport/storage and manufacturer guarantees. It excludes vehicle/tractor hoses, gas‑welding hoses and other special‑purpose hoses specified elsewhere.

Q: Who typically uses it?

A: Manufacturers of rubber hoses, procurement/specification engineers, plant maintenance teams in petrochemical, water/utility, food processing and construction sectors, and suppliers exporting to markets that accept or require GOST compliance.

Q: Is it current or superseded?

A: The standard was introduced with effect from 01 January 1981 and carries recorded amendments (indexed bulletins: ИУС 9‑81, 2‑86, 8‑87, 1‑90). Public standards catalogues and reprint listings show it as reissued/republished in later years; however legal/application status can vary by country and over time — for regulatory or procurement use, verify the current legal status and any national replacements or newer technical specifications with the relevant national standards body or official standards database before relying on it as the sole normative document.

Q: Is it part of a series?

A: It is one of the GOST family standards addressing hoses and references other GOSTs (materials, testing and climatic categories). Related hose specifications and later national or ISO standards cover complementary or more specialized hose types (see ICS categories for hose standards).

Q: What are the key keywords?

A: Rubber pressure hose, textile carcass, working pressure, climatic version, hydrostatic test, marking, Б (I) / В (II) / Г / ВГ / П / Ш / Пар classes, GOST 18698-79.
