GOST 19791-74 PDF

Full title and description

GOST 19791-74 — Смазка железнодорожная ЛЗ-ЦНИИ. Технические условия (Axle box grease LZ‑TsNII — Specifications). The standard specifies technical requirements, test methods and rules for acceptance, packaging and marking of the LZ‑TsNII railway axle‑box grease.

Abstract

This standard defines the composition, required physical and performance characteristics, test procedures and quality acceptance criteria for the railway axle‑box grease designated ЛЗ‑ЦНИИ (LZ‑TsNII). It is intended to ensure reliable lubrication of rolling‑stock axle boxes under typical operating conditions and to standardize manufacturing and testing for suppliers and laboratories.

Scope

Specifies technical requirements, test methods, acceptance rules, marking, packaging and storage conditions for the LZ‑TsNII axle‑box grease used in railway rolling stock. The standard applies to manufacturers of the grease, railway maintenance organizations, testing laboratories and purchasers specifying grease for axle boxes.

Key topics and requirements

• Designation and normative name of the grease (ЛЗ‑ЦНИИ / LZ‑TsNII).
• Required composition/constituents and typical additive classes (base oil, thickening system and performance additives) as defined by technical specification.
• Physical and performance properties to be met (examples: consistency/penetration, drop point, evaporation loss, load‑carrying or wear indicators — specific test methods referenced in the standard).
• Accepted test methods and references to other GOST standards for specific determinations (viscosity, evaporability, mechanical stability, etc.).
• Rules for sampling, acceptance, marking, packaging and storage suitable for railway application.

Typical use and users

Used by lubricant manufacturers and formulators producing axle‑box greases, rolling‑stock maintenance and repair depots, railway operators specifying lubricants for axle bearings, and accredited testing laboratories performing quality control and acceptance testing.

Related standards

The standard cites and is used together with related normative documents covering test methods and material properties (examples of referenced GOSTs appear in the normative list for the standard, including standards on grease test methods, petroleum products and packaging/marking rules). Typical referenced documents include a number of GOSTs on grease testing and petroleum products used as normative references in the specification.

FAQ

Q: What is this standard?

A: GOST 19791‑74 is a Soviet / interstate technical specification that sets requirements and test methods for the railway axle‑box grease designated ЛЗ‑ЦНИИ (LZ‑TsNII), used in rolling‑stock axle bearings.

Q: What does it cover?

A: It covers composition/identification, required physical and performance properties, sampling, test methods, acceptance criteria, packaging, marking and storage for the specified axle‑box grease.

Q: Who typically uses it?

A: Manufacturers of greases, railway maintenance organizations, procurement/specification engineers for rolling stock, and quality/testing laboratories use this standard to ensure compatibility and performance of axle‑box lubricants.

Q: Is it current or superseded?

A: The bibliographic records list ГОСТ 19791‑74 as in force (действует) with historical reprints; official records show approval in 1974 and entry into force 1 January 1975. Users should check the current national/regional standards database for any subsequent amendments or replacement standards when specifying in a given jurisdiction.

Q: Is it part of a series?

A: It is part of the family of GOST standards covering lubricants, greases and petroleum products and references multiple related GOST test‑method and material standards; it is not a multi‑part series by itself but belongs to the broader lubricant specification cluster.
