Under the agreement, the parties are in charge of doing their best to ensure that there are appropriate procedures in place to allow the use of traps and to enforce trap legislation in their area of jurisdiction. It is also recommended that the parties have trap formation in human devices/methods. The agreement also supports the inclusion of ISO testing methods in the Trap certification process.   In order to ensure the accuracy and reliability of fishing methods and to demonstrate that fishing methods meet the requirements of standard studies for the review of these fishing methods, they should follow the general principles of good experimental practices. To date, more than 200 trap models have been tested and certified to AIHTS certification standards. Almost all tests are conducted in Canada. These standards were approved by the International Independent Standards Organization (ISO) in 1999 and confirmed in 2004 as part of its five-year review. Standards are used by Canada and form the basis for trap implementation and certification, as provided for in the International Human Traps Standards (AIHTS) agreement, which are trained in the humane, safe and effective use of fishing methods, including new methods of development; and, as stated in Article 7 of the agreement, fishing methods must be checked to verify their compliance with these standards and certified as such by the competent authorities of the contracting parties, and they must develop and strengthen multilateral cooperation in the field of humane fishing methods, on the basis of mutual interest and desire to facilitate trade. To determine whether a fishing method is human or not, the welfare of a captured animal must be assessed. In 1991, Under massive pressure from the anti-fur lobby, the European Union (EU) has adopted Regulation 3254/91 prohibiting the importation into the EU of fur products from 13 species from each country, unless the use of jaw traps is banned in that country or the fishing methods used in that country comply with internationally agreed humane trapping standards. EU Regulation 3254/91 is still in force in the EU.
 AIHTS establishes accreditation and certification standards for all types of traps and requires traps to be certified in accordance with AIHTS, first until fall 2007. The agreement prohibits the use of retention and kill traps that are not certified to standards. However, it does not prevent individuals from constructing and using traps corresponding to the designs authorized by the competent authorities. (The relevant authorities are the legal bodies responsible for capture, including governments, government-mandated authorities and Aboriginal groups empowered to regulate wildlife management activities.) Cases that do not comply with treaty standards must be removed by the signatories. If there is no case for a given species, all legal traps of this type may continue to be used until certified traps are available and research continues to look for treaty-standard traps.  In reviewing fishing systems, it is necessary to assess an appropriate range of measures to ensure the welfare of captured animals. While these measures, in particular additional behavioural and physiological measures, have not been developed and have been used for a large number of species, their use in these standards for the species concerned must be verified by scientific studies conducted to determine initial values, areas of response and other relevant measures.
