Full title and description

St ISO 2261-1972 — Reciprocating internal combustion engines — Hand operated control devices — Standard direction of motion. This edition (1972) specifies the conventional direction of motion for manually operated controls used for speed regulation and reversing of reciprocating internal‑combustion engines. The 1972 edition has been withdrawn and replaced by ISO 2261:1994.

Abstract

The standard establishes a uniform direction of motion for hand‑operated control devices on reciprocating internal‑combustion engines (notably for marine and rail propulsion), to ensure consistent operator expectations whether the control is located at or remote from the engine. Valves for fluid control are excluded from its scope. The first edition was published in 1972 and later canceled and replaced by a 1994 edition.

General information

• Status: Withdrawn (revised/cancelled and replaced by ISO 2261:1994).
• Publication date: 1972-05 (first edition).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 27.020 — Internal combustion engines.
• Edition / version: Edition 1 (1972).
• Number of pages: 4 (1972 edition).

Scope

Applies to the direction of motion of hand‑operated control devices for speed regulation and reversing of reciprocating internal‑combustion engines, with particular attention to engines used for marine and rail propulsion. The standard is intended to standardize operator control movement expectations regardless of operator location; it excludes valves for the control of liquids and gases. Note: the 1972 edition has been superseded by the 1994 revision which carries the same scope.

Key topics and requirements

• Defined conventional direction(s) of motion for hand‑operated speed‑regulation controls (throttle/engine speed).
• Defined conventional direction(s) of motion for reversing controls on reciprocating engines.
• Applicability irrespective of operator position (local or remote).
• Explicit exclusion of valves for liquid and gas control from the standard's requirements.

Typical use and users

Used by engine designers, shipyards and marine equipment manufacturers, railway vehicle designers, control‑system integrators, technical authors of operator manuals, and regulatory/standards departments to ensure consistent control directions across products and installations. Maintenance and training teams also rely on the standard to define expected operator actions. (For current normative text, consult ISO 2261:1994.)

Related standards

Directly revised by ISO 2261:1994 (which cancels and replaces ISO 2261:1972). Related work falls under ISO/TC 70 (Internal combustion engines) and other standards addressing engine controls, operator interfaces and marine/rail equipment safety.

FAQ

Q: What is this standard?

A: ISO 2261:1972 is the first edition of a standard that specified the normal direction of motion for hand‑operated control devices used with reciprocating internal‑combustion engines. The 1972 edition has been withdrawn and replaced by ISO 2261:1994.

Q: What does it cover?

A: It covers the conventional directions of motion for manual controls used to regulate engine speed and to reverse reciprocating engines, with attention to marine and rail applications; valves for liquid/gas control are excluded.

Q: Who typically uses it?

A: Engine manufacturers, naval architects, rolling stock designers, control system engineers, technical writers, maintenance personnel and standards/quality teams — anyone who defines or implements operator controls on reciprocating engines.

Q: Is it current or superseded?

A: Superseded — ISO 2261:1972 was withdrawn and replaced by ISO 2261:1994 (Edition 2, published 15 December 1994). To obtain the current normative requirements, consult ISO 2261:1994.

Q: Is it part of a series?

A: It is a standalone ISO technical standard within the work of ISO/TC 70 (Internal combustion engines); it is related by subject matter to other ISO standards addressing engine controls and operator interfaces. The definitive lifecycle and revision information is recorded in ISO's catalogue (see ISO 2261:1994).

Q: What are the key keywords?

A: Reciprocating internal combustion engines; hand‑operated control devices; direction of motion; speed regulation; reversing; marine; rail; ISO 2261.
