GOST 2593-2014 PDF

Full title and description

GOST 2593-2014 — "Рукава соединительные железнодорожного подвижного состава. Технические условия" (English: Coupling hoses for railway rolling stock. Specifications). The standard specifies technical requirements for flexible coupling hoses used on railway rolling stock and metro vehicles, including air-brake and electro‑pneumatic connection functions.

Abstract

This standard defines materials, design features, dimensional and performance requirements, testing and marking for coupling (connecting) hoses used to join pneumatic lines (and associated electrical connections for electro‑pneumatic brakes) on locomotives, passenger cars, freight cars and metro rolling stock. It replaces the earlier GOST 2593-2009 edition and establishes requirements for hoses intended for service with compressed air up to 1.0 MPa and for detachable electrical circuit connections.

Scope

The standard applies to connecting (coupling) hoses designed for use on railway rolling stock and metro vehicles. It covers hoses intended for flexible connection of compressed‑air lines (for braking and auxiliary pneumatic systems) at service pressures up to 1.0 MPa and includes provisions for detachable electrical connections used in electro‑pneumatic braking circuits. Requirements include materials, construction, protective elements, performance, test methods and marking.

Key topics and requirements

• Designation, dimensions and construction types of coupling hoses (including hose ends, fittings and protective coverings).
• Materials and compatibility with compressed air and typical operating environments for rolling stock.
• Performance limits: working pressure up to 1.0 MPa, temperature and mechanical durability requirements.
• Electrical connection provisions where hoses incorporate detachable electro‑pneumatic circuit contacts.
• Testing procedures: pressure, leakage, mechanical strength, climatic and aging tests.
• Marking, packaging and acceptance rules for production and delivered items.

These aspects are specified to ensure interchangeability, safety of brake systems, and reliable service on rail and metro networks.

Typical use and users

Manufacturers of railway hoses and brake equipment, rolling stock OEMs and suppliers, maintenance and overhaul depots, technical regulators, conformity assessment bodies and procurement specialists use this standard to specify, manufacture, test and accept coupling hoses for locomotives, passenger and freight cars and metro rolling stock.
