Full title and description

ISO 10263-5:2009 — Earth-moving machinery — Operator enclosure environment — Part 5: Windscreen defrosting system test method. This part defines a standardized test method for assessing the performance of windscreen defrosting systems fitted to operator enclosures of earth‑moving machinery; available as a PDF (electronic) or paper publication.

Abstract

Specifies a test method to determine the performance of windscreen defrosting systems for earth‑moving machines equipped with an operator enclosure. The standard covers procedures that can be carried out using commercially available laboratory test equipment as well as in appropriate outdoor test conditions.

General information

• Status: Published (confirmed at systematic review).
• Publication date: 5 February 2009.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 53.100 (Earth‑moving machinery).
• Edition / version: Edition 2 (2009).
• Number of pages: 10.

Scope

Applies to earth‑moving machines fitted with an operator enclosure and a device for defrosting the windscreen. The document provides a reproducible test procedure to evaluate defrosting performance (for example time to achieve acceptable visibility and the ability to remove ice/frost under specified ambient conditions), and is suitable for both laboratory simulation and controlled outdoor testing.

Key topics and requirements

• Definition of test conditions and environmental parameters for defrosting tests (ambient temperature, humidity, wind conditions or their laboratory equivalents).
• Test setup and instrumentation for measuring defrost performance (temperature sensors, visibility checks, timing of defrost cycles).
• Procedures for laboratory and outdoor test execution to ensure repeatability and comparability.
• Performance metrics and observations (defrosting time, area cleared, residual ice/fog, operator visibility criteria).
• Reporting format and required test data to document results and support comparisons between systems.

Typical use and users

Used by earth‑moving machinery manufacturers (OEMs), component suppliers, independent test laboratories, conformity assessment bodies, R&D teams developing cab climate systems, and safety/regulatory authorities assessing operator visibility and enclosure climate performance.

Related standards

FAQ

Q: What is this standard?

A: ISO 10263‑5:2009 is an ISO test method that specifies how to assess the performance of windscreen defrosting systems on earth‑moving machines equipped with operator enclosures.

Q: What does it cover?

A: It covers reproducible test procedures (laboratory and appropriate outdoor tests), instrumentation/measurement guidance and the reporting of defrost performance to determine how effectively a system clears windscreen frost/ice and restores acceptable visibility.

Q: Who typically uses it?

A: OEMs, component suppliers, independent test laboratories, regulatory/certification bodies and R&D teams working on cab climate, defrosting and visibility performance for construction and earth‑moving equipment.

Q: Is it current or superseded?

A: The 2009 edition (Edition 2) is published and was last reviewed and confirmed through ISO’s systematic review process (confirmed in 2025), so the 2009 edition remains the current version.

Q: Is it part of a series?

A: Yes — ISO 10263 is a multipart series addressing operator enclosure environment; Part 5 is one part of that series and is intended to be used alongside related parts (for example Parts 1–4 and 6) where applicable.

Q: What are the key keywords?

A: Windscreen defrosting, defogging, operator enclosure, cab climate, earth‑moving machinery, performance test, HVAC testing, visibility criteria.
