6.3 Members are encouraged, at the request of other Members, to be ready to enter into negotiations for the conclusion of mutual recognition agreements on the results of each other`s conformity assessment procedures. Members may require that such agreements meet the criteria set out in paragraph 1 and that they be mutually exclusive as to their potential to facilitate trade in the products concerned. 3. Citizens of the parties to the dispute may not be active in a group of technical experts without the joint consent of the parties to the dispute, unless the panel considers, in exceptional cases, that the need for specialized scientific expertise cannot be met by other means. Government representatives of the parties to the dispute are not allowed to attend a group of technical experts. Members of technical expert panels serve in their individual capacity and not as representatives of the government or an organization. Governments or organizations are therefore not allowed to give them instructions on matters before a group of technical experts. 10.7 Where a Member has concluded an agreement with one or more other countries on matters relating to technical regulations, standards or conformity assessment procedures that may have a significant impact on trade, at least one Member of the Party shall communicate to the other Members, through the Secretariat, the products to be covered by the Agreement and shall include a brief description of the Agreement. The members concerned are invited to enter into consultations with other members upon request in order to conclude similar agreements or to organize their participation in such agreements. The TBT aims to ensure that technical regulations, standards, tests and certification procedures do not create unnecessary barriers to trade. The agreement prohibits technical requirements created to restrict trade, as opposed to technical requirements created for legitimate purposes such as consumer or environmental protection.  Its purpose is to avoid unnecessary barriers to international trade and to grant all WTO Members recognition of the protection of legitimate interests in accordance with their own regulatory autonomy, although the application of international standards is encouraged.
