ISO 5006:2017

Overview - ISO 5006:2017 at a glance

ISO 5006:2017 - "Earth-moving machinery - Operator’s field of view - Test method and performance criteria" defines a static test method and measurable performance criteria for assessing an operator’s field of view on earth‑moving machines with a seated operator. The standard uses two light sources placed at the operator eye location (filament position centre point, FPCP) to determine visibility on a 12 m visibility test circle (VTC) and along a rectangular boundary (RB) located 1 m from the machine perimeter. It applies to machine families defined in ISO 6165 up to the maximum operating mass per ISO 6016; other or larger machines use the test procedures together with the risk‑assessment process in clause 10.4.

Key topics and technical requirements

• Test method: Static measurements using twin light bulbs at the operator eye position (FPCP) to map shadows ("maskings") on the VTC and RB.
• Visibility zones: The area around the machine is divided into six sectors (A–F) to evaluate front, side and rear visibility.
• Human factors: Nominal binocular eye spacing of 65 mm is used; allowed eye‑spacing adjustments up to 405 mm (front sectors) and 205 mm (rear sectors) account for head/torso movement.
• Masking criteria: Maskings caused by the machine, attachments or ROPS are quantified; a 300 mm masking dimension on the RB approximates chest depth for nearby personnel. Multiple maskings are allowed if adequately spaced.
• Indirect visibility aids: Rules and performance criteria for mirrors and CCTV systems (with preferred use for RB) are included to mitigate inadequate direct view.
• Reporting & documentation: Test report requirements and suggested visibility information to be included in the operator’s manual.
• Risk assessment: For machines not listed in Table 1/2 (e.g., larger or derivative types), test procedures are used with a documented risk assessment (10.4).

Practical applications - who uses ISO 5006:2017

• OEMs and design engineers: to evaluate and optimize cab layout, glazing, ROPS and attachment layouts for improved operator visibility.
• Safety engineers & compliance officers: to quantify blind spots, validate indirect aids (mirrors/CCTV) and meet safety specifications.
• Certification bodies & test labs: for repeatable, objective visibility testing and performance comparison across machine families.
• Fleet managers & procurement: to compare machines on operator visibility metrics and reduce site incident risk.
• Jobsite planners & trainers: to incorporate visibility limitations into jobsite organization and operator procedures.
