ISO, the International Organization for Standardization, formed a technical committee in 1987 to develop an international standard for humane traps. This effort began with the establishment of international Working Groups charged with preparing standards for killing and restraining traps. Capture efficiency, humaneness, injury thresholds, selectivity, testing, and safety are addressed in the standards. A final draft standard could be voted on by ISO member countries by mid-1995.
