ISO 10990-4:1999

Overview

ISO 10990-4:1999 - "Animal (mammal) traps - Part 4: Methods for testing killing-trap systems used on land or underwater" defines standardized test methods for evaluating the performance of killing-trap systems used on land and in submersion sets for semi‑aquatic mammals. The standard focuses on objective performance metrics including effective killing, mechanical behaviour, pathological evaluation, selectivity, capture efficiency and user safety. Annex A provides informative mechanical testing guidance; Annex B contains a normative pathology protocol.

Key topics and technical requirements

• Scope and definitions: clear terminology for capture efficiency, selectivity, impact momentum, clamping force, target/non‑target animals, trap opening and killing‑trap system.
• Sampling and replicates: randomized selection of specimens and sufficient replicates to allow statistical comparison while considering animal welfare.
• Mechanical testing:
  • Clamping force measured with static load cells across trap openings.
  • Impact momentum and impact force determined via accelerometers and dynamic load cells (including procedures for underwater testing for submersion systems).
  • Test rig and substrate requirements to protect measuring equipment.
• Biological/kill testing:
  • Tests on anaesthetized animals to evaluate loss of corneal/palpebral reflexes and time to cardiac arrest under veterinary supervision (identifies limits of extrapolating to conscious animals).
  • Test-room, tank/compound evaluations and field tests to assess real‑world killing effectiveness.
• Selectivity and capture efficiency: measured percentages of target vs non‑target captures and potential captures (caught plus identifiable escapes).
• Pathological evaluation: standardized pathology protocol (Annex B) for assessing injury and cause of death.
• User safety and reporting: inspection procedures for operator safety and detailed test reporting requirements (trap settings, force measurements, velocity/momentum data, strike locations).

Practical applications

• Provides a consistent framework for manufacturers to validate trap designs and prepare performance documentation.
• Used by regulatory bodies and certification agencies to set approval criteria and compare control traps.
• Supports wildlife managers, researchers and animal welfare organizations in assessing humane performance, selectivity and field effectiveness of killing-trap systems.
• Applicable to testing both terrestrial killing traps and submersion sets for semi‑aquatic mammals.

Related standards

• ISO 10990 series (Parts 1–5): Part 1 (mechanically powered killing traps), Part 2 (restraining traps), Part 3 (submersion killing traps), Part 5 (methods for testing restraining traps).
• Complementary to national regulations and animal welfare guidelines - tests must follow jurisdictional requirements.
