GOST 11479-75 PDF

Full title and description

GOST 11479-75 — "Системы автоматического регулирования частоты вращения (САРЧ) судовых, тепловозных и промышленных дизелей. Приемка и методы испытаний" (Automatic rotational speed control / Automatic speed control systems (ARFCS) of marine, locomotive and industrial diesel engines — acceptance rules and test methods). This standard specifies acceptance criteria and standardized test procedures for speed-control systems fitted to marine, locomotive and industrial diesel engines.

Abstract

GOST 11479-75 sets out the requirements, measurement tolerances and test methods used to verify performance of automatic speed-control systems (САРЧ / ARFCS) for piston diesel engines used in ships, locomotives and industrial installations. It defines test instrumentation accuracy, stability and transient-response checks, procedures for simulating load changes, and acceptance criteria for different accuracy classes.

General information

• Status: Withdrawn / Утратил силу (no longer current in the Russian Federation as of 2013).
• Publication date: Introduced 01 January 1978 (approved 28 May 1975; designation year 1975 — GOST 11479-75).
• Publisher: Approved by the State Committee for Standards of the USSR (Gosstandart); later reissued/printed by IPK — Publishing of Standards (Moscow).
• ICS / categories: Control systems and measurement for reciprocating diesel engines; testing and acceptance of engine control equipment (marine, locomotive, industrial applications).
• Edition / version: GOST 11479-75 (original 1975 designation; introduced 1978). Amendments published (e.g., amendments in 1983 and 1987 were recorded in later reprints).
• Number of pages: 7 pages (short normative document).

Scope

The standard applies to automatic speed-control systems (САРЧ / ARFCS) installed on marine, locomotive (diesel-electric or diesel-hydraulic traction) and industrial diesel engines. It establishes rules for acceptance testing and the methods to be used to determine compliance with specified performance parameters (accuracy classes, stability, transient response, power and torque measurement accuracy, and test conditions).

Key topics and requirements

• Definitions and classification of САРЧ (ARFCS) by application and accuracy class.
• Acceptance test procedures, including steady-state tests, stability (frequency instability) measurements, and transient-response tests (including imitation of instantaneous load changes).
• Instrument and measurement accuracy requirements (examples in the standard: permitted RPM measurement errors for various classes — e.g., ±0.1% for 1st-class single-mode regulators, ±0.2% for 2nd-class single-mode regulators, larger tolerances for locomotive diesel-generator sets and other systems).
• Permitted measurement errors for power and torque instrumentation and references to related measurement standards (e.g., torque measurement conformity to GOST 10448 as cited in the text).
• Acceptance criteria and pass/fail rules for delivered systems, including required test set-up, instrumentation calibration, and environmental/test loading conditions.

Typical use and users

Primary users are diesel engine and governor manufacturers, marine and locomotive builders, test laboratories, commissioning engineers, maintenance organizations and conformity/inspection bodies that perform acceptance testing of engine speed-control systems. The standard was intended for use during factory acceptance tests, ship/locomotive commissioning and in-service testing.

Related standards

GOST 11479-75 references and is used alongside other standards governing measurement methods and engine tests (for example, it cites GOST 10448 for torque-measuring requirements). It is part of a family of GOST documents covering diesel engine testing, control-device specifications and instrumentation accuracy; users typically consult related GOSTs on engine performance tests and measurement technique when applying this standard.

FAQ

Q: What is this standard?

A: It is a Soviet / interstate GOST standard (GOST 11479-75) that defines acceptance criteria and standardized test methods for automatic speed-control systems of marine, locomotive and industrial diesel engines.

Q: What does it cover?

A: The standard covers classification of ARFCS/САРЧ, required instrumentation accuracy, steady-state and transient tests (including simulation of instantaneous load changes), criteria for stability and response, and acceptance/pass criteria for delivered control systems.

Q: Who typically uses it?

A: Manufacturers of governors and speed-control equipment, engine builders, shipyards, locomotive manufacturers, commissioning and testing laboratories, and inspection/conformity bodies involved in acceptance testing of diesel-engine control systems.
