GOST 33798.1-2016 PDF

Full title and description

GOST 33798.1-2016 — "Electric equipment for railway rolling stock. Part 1. General service conditions and specifications". This межгосударственный (GOST) standard establishes general service conditions, constructional and performance requirements, and test provisions for electric equipment used on railway rolling stock; it is presented as a modification of IEC 60077-1:1999 for application within the CIS/Russian national system.

Abstract

GOST 33798.1-2016 defines classification, environmental and operational service conditions, rated values (voltages, currents), insulation and dielectric requirements, mechanical and thermal performance, information and marking, acceptance rules, and test methods applicable to electrical equipment installed on railway vehicles. The standard is aligned with the international IEC 60077-1 framework but includes national (modifying) provisions for use as a national standard of the Russian Federation.

General information

• Status: Active / introduced as a national standard of the Russian Federation (implemented as a межгосударственный standard).
• Publication date: Introduced into effect 01 May 2017 (approved by Rosstandart order No. 1308‑ст dated 05 Oct 2016; standard designation year 2016).
• Publisher: Adopted by the Federal Agency for Technical Regulation and Metrology (Rosstandart); official printed edition published in Moscow (Standartinform).
• ICS / categories: ICS 45.020 (railway rolling stock; electrical equipment classification).
• Edition / version: GOST 33798.1-2016 (edition introduced 2017-05-01; based on IEC 60077-1:1999 with national modifications).
• Number of pages: Approximately 54–56 pages depending on edition/printing (catalog and publisher listings report 54 and 56 pages in different editions).

Scope

The standard applies to electrical equipment intended for installation on railway rolling stock (power circuits, auxiliary systems, control and signaling circuits and components). It sets general service conditions (environmental and operational), classification rules, required characteristics (electrical, mechanical, thermal), marking and information requirements, acceptance criteria, and methods and conditions for type and routine testing. It is intended as the baseline general-part standard; more specific equipment types are covered by subsequent parts or separate component standards.

Key topics and requirements

• Classification of equipment by rated voltage, current, frequency and utilization category, and definition of equipment categories for different duty and environmental classes.
• Service conditions: ambient temperature ranges, altitude, humidity, vibration and shock, pollution, chemically active atmospheres, biological influences, and overvoltage/impulse considerations.
• Electrical requirements: rated operational and insulation voltages, dielectric and impulse test voltages, short‑time and making/current withstand capabilities, grounding and return-current practices.
• Mechanical and thermal performance: mechanical endurance (cycle counts), temperature rise limits, creepage/clearance dimensions and insulation coordination for the railway environment.
• Testing and verification: type tests, routine tests, climatic, vibration, dielectric, EMC and performance tests with specified test conditions and acceptance rules.
• Information, marking and documentation: required product marking, technical data to be supplied, and information for installation, operation and maintenance.
• Conformance relationship: the standard is presented as modified from IEC 60077-1:1999 and is intended to be used together with Parts 2 (electrotechnical components) and other related national parts.

Typical use and users

Primary users are rolling stock electrical and systems engineers, component and equipment manufacturers, test laboratories, conformity assessment and certification bodies, railway operators and maintenance organizations involved in design, procurement, type‑approval and routine testing of electrical equipment for locomotives, EMUs, DMUs and other railway vehicles. Regulatory bodies and standards developers also use the document as the baseline general-part reference.

Related standards

GOST 33798.1-2016 is part of a multi‑part series derived from the IEC 60077 series. Related documents include GOST 33798.2-2016 (Electrotechnical components — general specifications) and other parts and national standards that cover specific components, testing methods and application rules; the international reference is IEC 60077 (series) and regional/adopted equivalents (EN/ISO variants).
