GOST 34650-2020 PDF

Full title and description

GOST 34650-2020 — "Колеса цельнокатаные и бандажи колесных пар железнодорожного подвижного состава. Методы неразрушающего контроля" (English title: "All-rolled wheels and tyres for railway rolling stock. Nondestructive inspection methods"). The standard specifies methods, means and procedures for nondestructive testing (NDT) of solid-rolled wheels and wheel-tyres (bandages) of railway wheelsets used in rolling stock.

Abstract

This standard establishes requirements for visual, magnetic-particle, ultrasonic and other non-destructive inspection methods, acceptance criteria, metrological support and safety measures applied during factory acceptance, finishing and other control operations on solid-rolled wheel rims and wheel tyres (bandages) of railway rolling stock. It includes mandatory schemes for ultrasonic and magnetic inspection and references normative documents for methods and equipment.

Scope

GOST 34650-2020 applies to solid-rolled wheels and wheelset tyres (bandages) of railway rolling stock and sets forth mandatory requirements for nondestructive control performed during acceptance and other production and inspection stages. The standard covers selection of NDT methods, test procedures for detecting both surface and internal defects, residual stress control in rims and bandages, metrological support, required diagrams/schemes for ultrasonic and magnetic inspection, and occupational safety provisions related to NDT operations.

Key topics and requirements

• Specified NDT methods: ultrasonic testing for internal defects; magnetic-particle testing for surface and near-surface defects; visual and optical inspection; eddy-current methods where applicable.
• Acceptance criteria and defect classification for wheels and tyres (surface vs internal defects; critical locations: rim, flange, tread, bandage seating areas).
• Mandatory inspection schemes/diagrams for ultrasonic scanning of bandages and solid-rolled wheels (included as normative appendices).
• Requirements for measurement and metrological support of NDT equipment and procedures (calibration, reference blocks, probes).
• Procedures for checking and controlling residual stresses in wheel rims and bandages.
• Documentation, test records and traceability requirements for acceptance testing.
• Occupational safety and environmental requirements for NDT operations (magnetizing, use of couplants, noise, and general safety clauses).

Summarized from the standard’s clauses and normative annexes.

Typical use and users

Primary users are wheel and wheelset manufacturers, rolling-stock component suppliers, in-house and third-party NDT laboratories, acceptance/quality inspectors at production plants, maintenance depots performing wheel re-profiling and inspection, certification bodies and regulatory organizations overseeing railway equipment conformity and safety. The standard is used to define factory acceptance tests, routine inspections after re-profiling, and to support QA/QC programs for wheel production.

Related standards

GOST 34650-2020 refers to and is used alongside a number of related standards, for example: GOST 10791-2011 (technical conditions for solid-rolled wheels), GOST 32207-2013 (methods for determining residual stresses in wheels), GOST R 56542-2015 (classification of NDT types and methods) and other GOST and ISO/EN guidance on specific NDT methods (ultrasonic, magnetic-particle, visual). It is also part of a family of railway wheel/axle/wheelset NDT documents (see companion standards for axles, wheel centers and wheelset assembly).
