GOST 33435-2015 PDF

Full title and description

GOST 33435-2015 — "Устройства управления, контроля и безопасности железнодорожного подвижного состава. Требования безопасности и методы контроля" (English: "Control, monitoring and safety means of railway rolling stock. Safety requirements and control methods"). The standard sets safety, design and control/testing requirements for onboard control, monitoring and safety devices used on railway rolling stock.

Abstract

GOST 33435-2015 specifies mandatory safety requirements, design and construction rules, environmental and mechanical endurance criteria, software and electrical-safety provisions, and methods of verification and testing for devices that provide control, monitoring and safety functions on railway vehicles. It also describes required technical documentation, acceptance tests and measures for protection against electrical/fire hazards and static discharge.

Scope

This standard applies to devices newly developed, modernized or procured for installation on railway rolling stock that perform control, monitoring or safety functions. It is intended to be used by manufacturers, designers, testing laboratories and operators to ensure onboard equipment meets uniform safety, environmental and functional reliability requirements and to define methods for verifying conformity through tests and inspections.

Key topics and requirements

• General safety requirements for control/monitoring/safety devices on rolling stock (electrical, mechanical and fire-safety aspects).
• Design and constructive requirements, including protection classes, mounting categories (cab, underframe, bogie), and materials/finish expectations.
• Environmental and mechanical resistance: climatic categories, vibration and shock resistance, and testing in accordance with relevant GOST/IEC methods.
• Electrical safety: grounding, protection against short circuits and overheating of wiring, and static-discharge protections.
• Requirements for software in programmable devices with safety functions (documentation, validation and safety-related measures).
• Acceptance, type and routine tests: methods for verifying conformity to the standard’s requirements and for documentation of test programs and protocols.
• Required technical documentation and, where applicable, materials constituting the "safety case" or "evidence of safety" for devices with safety functions.

Typical use and users

Primary users are manufacturers and designers of onboard railway control, monitoring and safety equipment, certification bodies, railway operators and maintenance organizations, and testing laboratories performing type-approval and acceptance tests. System integrators and procurement specialists use the standard to specify requirements in contracts and technical specifications.

Related standards

GOST 33435-2015 references or aligns with a number of normative documents and national standards governing fire safety, electrical safety, environmental/climatic categories and test methods — for example, references to national fire-safety regulations and standards equivalent to ГОСТ 12.1.004, ГОСТ 12.1.044, ГОСТ 31613, ГОСТ 15150 and related test standards for vibration/shock (e.g., ГОСТ Р 54434 / EN 61373 equivalents). When using GOST 33435-2015 it is common to consult the later consolidated GOST 33435-2023 and the other referenced GOSTs for up-to-date cross-references.
