Full title and description

ISO 10266:1992 — Earth-moving machinery — Determination of slope limits for machine fluid systems operation — Static test method. Specifies laboratory test procedures for establishing the static slope capability of machine fluid systems (engine, power train, fuel, lubrication, cooling, hydraulic actuation and other liquid-containing systems) using a tilt platform or prepared slope, with an alternative test-bench method and a model test report in an annex.

Abstract

This International Standard defines how to determine the maximum static slope (expressed in degrees) at which fluid systems of earth‑moving machines can operate without malfunction or damage. It describes preferred and alternative test arrangements, required machine orientations for testing, stabilized temperature conditions, safety precautions and reporting (Annex A). The standard applies to earth‑moving machines as defined in ISO 6165 and is intended for laboratory evaluation of limiting performance parameters of liquid‑containing systems.

General information

• Status: Published (confirmed).
• Publication date: December 1992 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 53.100 (Earth‑moving machinery).
• Edition / version: Edition 1 (1992-12).
• Number of pages: 3.

Scope

Applies to earth‑moving machines (as referenced in ISO 6165) and covers laboratory procedures to determine the static slope capability of machine fluid systems. The preferred method tests the complete machine on a tilt platform or prepared slope; the alternative is testing complete fluid systems on a test bench. The standard addresses longitudinal and lateral orientations, stabilized operating temperature criteria and the form of the test report (Annex A).

Key topics and requirements

• Definition of static slope capability and stabilized operating temperature criteria for fluid systems.
• Preferred test method: whole‑machine testing on a tilt platform or prepared slope (longitudinal and lateral orientations specified).
• Alternative test method: complete fluid‑system testing on a test bench where appropriate.
• Safety precautions and test‑setup requirements to protect personnel and equipment during tilting tests.
• Measurement and acceptance parameters for fluid system performance under inclination (e.g., fuel delivery, lubrication, cooling, hydraulic actuation behavior).
• Annex A: model test report format to ensure consistent recording and presentation of results.

Typical use and users

Used by earth‑moving machine manufacturers (OEMs), component suppliers, test laboratories, type‑approval and certification bodies, safety and reliability engineers, R&D and test departments, and regulatory authorities concerned with machine performance and safety on slopes. Also useful for maintenance organizations and equipment purchasers who need verified slope‑operation data.

Related standards

Standards and documents commonly referenced alongside ISO 10266 include ISO 6165 (earth‑moving machinery — basic types / vocabulary and machine classification), and other ISO standards on machine safety and test methods for earth‑moving machinery (for example, standards on safety labels and operator controls). ISO 10266 has also been adopted or published as national equivalents in some countries (for example PN‑ISO 10266:1996 and national listings in other member bodies).

Q: What does it cover?

A: It covers preferred and alternative static test methods (tilt platform or test bench), required orientations and test conditions, performance limits for fluid systems (engine, power train, fuel, lubrication, cooling, hydraulics), safety precautions and a model test report (Annex A).

Q: Who typically uses it?

A: Machine manufacturers (OEMs), test laboratories, certification bodies, safety engineers, R&D/test departments, maintenance teams and regulators involved with earth‑moving equipment performance and safety.

Q: Is it current or superseded?
