Overview
ISO 8811:2000 - "Earth‑moving machinery - Rollers and compactors - Terminology and commercial specifications" standardizes the language, commercial data and dimensional symbols for rollers and compactors used in earth‑moving and paving work. It covers self‑propelled, towed, walk‑behind (pedestrian) and attachment‑type compactor machines and defines machine types, nomenclature, key masses and vibration terms, and the commercial information manufacturers should publish.
Key topics and requirements
ISO 8811 organizes technical and commercial information to ensure consistent specification and communication:
- Terminology and definitions - clear definitions for terms such as roller, landfill compactor, base machine, equipment, attachment, operating mass, shipping mass, mass of vibrated/isolated parts, frequency, eccentric moment, centrifugal force and nominal amplitude.
- Machine types - classification of rollers and compactors (static/dynamic single, dual, three‑ and four‑drum rollers; pneumatic‑tyred rollers; trench rollers; tow‑behind and pedestrian units; combined machines).
- Nomenclature and component names - standardized labels for engines, drums, scrapers, water tanks, steering yokes, ballast, mats and other common parts used in commercial literature and drawings.
- Dimensions and symbols - defined dimension symbols (e.g., D1, D2, W91, R11) and diagrammatic references to describe drum diameters, drum widths, turning radii, kerb clearance and other geometric data.
- Masses, vibration and loads - definitions and conventions for presenting operating mass, shipping mass, linear load (for smooth drums), surface pressure (for padfoot/sheep‑foot drums) and theoretical surface pressure (for pneumatic tyres).
- Performance parameters - requirements for reporting engine net power, maximum travelling speeds, permitted inclination angles and gradeability.
- Commercial literature - guidance on the specifications that manufacturers should include in brochures and data sheets so purchasers can compare machines objectively.
Applications and users
ISO 8811 is intended for:
- Manufacturers preparing technical data sheets, product catalogs and drawings for rollers and compactors.
- Procurement specialists and fleet managers comparing machines for roadworks, site compaction or landfill operations.
- Design and specification engineers writing tender documents or machine performance requirements.
- Test labs and certification bodies referencing standardized terminology and presentation formats.
- Operators and maintenance teams who rely on consistent naming and specification to select correct parts and attachments.
Related standards
ISO 8811 references and aligns with other earth‑moving standards, for example:
- ISO 6014 (ground speed determination)
- ISO 6016 (mass measurement methods)
- ISO 6746 series (machine and equipment dimension symbols)
- ISO 9249 (engine net power test code)
Using ISO 8811 helps ensure clear communication, consistent commercial specifications and accurate comparison of rollers and compactors across manufacturers and markets.
