1.1 This part of ISO 10990 specifies methods for use in performance testing of traps used on land to restrain

mammals. The performance testing includes methods for evaluation of trauma, selectivity, capture efficiency and

user safety.

1.2 It is recognized that injury is only one component of animal welfare. However, there are insufficient data

collected in a scientific manner on the additional components to allow for the complete assessment of animal

welfare. Several areas of investigation are presented for evaluation in annex A. Selection of the data collection

methodology is left to the investigator. However, it is assumed that such collection methods will follow accepted

practices.

It should also be understood that data collected in any, or all, of the suggested areas will probably not provide an

absolute measure of welfare. Rather, the compilation of such data over time should provide a mechanism for

comparing the relative animal welfare impacts of different restraint methods.
