ISO 10990-5:1999

Overview

ISO 10990-5:1999 - "Animal (mammal) traps - Part 5: Methods for testing restraining traps" specifies standardized methods for performance testing of land-based restraining traps. The standard focuses on measuring trap impacts in four performance areas: trauma (pathology), selectivity, capture efficiency, and user safety. It establishes field-testing principles, sampling guidance, pathological examination procedures (annex B is a normative pathology protocol), and reporting requirements. The document also recognizes that injury is only one component of animal welfare and provides suggested research areas (Annex A) for broader welfare evaluation.

Key topics and requirements

• Scope and intent: Methods applicable to traps used on land to restrain mammals; testing addresses trauma, selectivity, capture efficiency and user safety.
• Sampling: Random selection of traps from submitted lots; replicate numbers must be sufficient for statistical significance as determined by the implementing authority while considering animal welfare.
• Field testing: Set traps per manufacturer instructions, document site (longitude/latitude, habitat), photograph sets and trapped animals, and check traps daily (once every 24 h).
• Pathological assessment: Veterinary pathologist performs post-mortem, radiological and (when needed) histological exams per the pathology protocol (Annex B). Radiology is recommended for traps that use striking/clamping forces; histology samples are specified for internal-organ assessment.
• Euthanasia and handling: Euthanize captured animals using methods that do not obscure trap-related trauma; live-removal and clinical examination are allowed where conservation concerns apply.
• Selectivity & capture efficiency: Record target vs non-target captures and calculate selectivity and capture efficiency metrics per definitions in the standard.
• User safety: Inspect and test trap designs and recommended safety devices; field observations of operator safety are recorded.
• Reporting: Comprehensive test report items are defined (site details, trap-nights, species, escapes, pathology protocol results, etc.).

Applications and users

ISO 10990-5 is used by:

• Trap manufacturers for product development, certification and design improvements.
• Independent test laboratories and certification bodies to evaluate performance and compliance.
• Wildlife managers, researchers and veterinarians conducting humane-wildlife or population-control studies.
• Regulators establishing legal trapping standards and permitting requirements.

Practical uses include comparative performance testing, welfare impact assessment over time, certification of restraining-trap systems, and informing policy or best-practice guidance.
