ISO 7134:2013

Overview - ISO 7134:2013 (Graders terminology & commercial specifications)

ISO 7134:2013 establishes standardized terminology and the required content of commercial literature specifications for graders and their equipment. It defines the names, masses, performance terms and dimensional references used for self‑propelled wheeled graders (including attachments such as scarifiers, rippers, snowploughs and front blades). The standard supports consistent product descriptions in technical data sheets, sales literature and regulatory or procurement documents for earth‑moving machinery.

Key topics and technical requirements

• Terms and definitions: Clear definitions for grader, base machine, equipment, attachment, component, operating mass, shipping mass, net power and other essential terms.
• Masses and performance: Rules for reporting operating mass (including operator, fluids and specified equipment), shipping mass, and net engine power (in line with ISO 15550).
• Base machine classification: Types by undercarriage (four‑ or six‑wheel), engine number and location (front or rear), steering systems (front‑wheel, articulated, or both), drive systems (2WD/4WD/6WD) and axle/drive configurations.
• Dimensions and nomenclature: Standardized coordinate reference (X, Y, Z, GRP) and nomenclature for grader components to ensure consistent dimensional data and drawings; Annex A and B cover equipment and attachment dimensions.
• Attachments: Standard terms, dimensional references and part nomenclature for scarifiers, rippers, snowploughs and front blades.
• Commercial literature content: Mandatory and recommended items for product specifications in SI units: engine details (manufacturer, type, displacement, net power, torque, cooling, fuel), transmission, axles, steering type and performance (turning radius per ISO 7457), brakes, tyres, hydraulic system data, system fluid capacities, masses and overall dimensions.

Practical applications and benefits

• Ensures consistent product data sheets for manufacturers and dealers, improving buyer confidence and enabling straightforward comparison between grader models.
• Supports procurement and tendering by providing unambiguous specification items for contracts, rental agreements and public works tenders.
• Aids technical writers and marketing teams in producing compliant commercial literature and datasheets.
• Helps design engineers and regulatory bodies by providing common terminology and dimensional references for testing, certification and interoperability of attachments.

Who uses ISO 7134:2013

• Grader and attachment manufacturers
• Equipment dealers, rental companies and fleet managers
• Procurement officers and specifiers in construction and civil works
• Test laboratories, certification bodies and standards committees
• Technical authors producing datasheets and manuals
