ISO 8589:2007

Overview

ISO 8589:2007 - Sensory analysis: General guidance for the design of test rooms - provides practical, product‑neutral guidance for designing sensory testing facilities. It defines the essential and desirable requirements for a sensory test room complex, including the testing area, preparation area, and office, to enable controlled sensory evaluations with minimum distraction and bias. ISO 8589:2007 applies to food and non‑food sensory testing but does not cover specialized inspection or in‑plant quality‑control facilities.

Key topics and technical requirements

• Test room layout: recommends separate but proximate testing and preparation areas to facilitate sample presentation while preventing cross‑contamination (odour, noise) and assessor bias. Annex A provides example layouts.
• Testing area and booths:
  • Individual booths or group areas for different test types; booths reduce distractions and communication.
  • Minimum booth working surface recommendations (for example, about 0.9 m wide × 0.6 m deep) and ergonomic clearances (e.g., ~0.35 m between seat and working surface).
  • Booth dividers should extend beyond the counter (≈ 0.3 m) and may be full height for privacy; at least one booth should accommodate wheelchair access.
  • Interior booth colour guidance (matt grey luminance ~15% - Munsell N4–N5; higher luminance for light/near‑white comparisons).
• Environmental control:
  • Temperature shall be controlled; relative humidity controllable when it affects products.
  • Noise minimization and sound‑resistant construction recommended.
  • Odour control: use easy‑to‑clean, low‑odour materials; air systems with activated carbon filters and slight positive pressure can help.
• Lighting:
  • Uniform, controllable lighting free of strong shadows. Examples: correlated colour temperatures around 6500 K (northern daylight) or 5000–5500 K for noon daylight; special lighting or filters may be used for colour masking or simulation.
• Preparation area & office: separate space for sample preparation, storage and administration; fittings and sanitation measures appropriate to the testing type (sinks, ventilation, safety).
• Safety and accessibility: signage, ventilation hoods, and provisions for assessors with disabilities.

Applications

• Designing or refurbishing sensory testing laboratories, panel rooms, or consumer test facilities.
• Establishing standardized conditions for product development, sensory research, and trained panel assessments.
• Guiding architects, lab managers, QA teams, and sensory scientists on test room design, booth configuration, and environmental controls.

Who should use this standard

• Sensory scientists and panel managers
• Food and non‑food product developers
• Laboratory designers and architects
• Quality and R&D teams planning sensory facilities
