Where international standards exist, members use them as the basis for their technical regulations, standards and compliance assessment procedures, unless, in certain circumstances (e.g. B for climatic or technological reasons), their use is either inadequate or ineffective to achieve the objective pursued (s. 2.4, 5.4 and Appendix 3.D).  2.9.1 may issue a notice in a publication in a timely manner to allow interested parties of other interested members to familiarize themselves with it in the event of intervention of specific technical regulations; 11.8 When advising and providing technical assistance to other members covered in paragraphs 1 to 7, members prioritize the needs of the least developed countries. 2.4 Where technical requirements are required and relevant international standards exist or are in the process of being completed, members use them or their relevant parties as the basis of their technical regulations, unless these relevant international standards or parties are an ineffective or inappropriate means of achieving legitimate objectives, for example due to fundamental climatic or geographic factors or fundamental technological problems. Although the TBT agreement applies to a wide range of industrial and agricultural products, health and plant health measures and procurement specifications are subject to separate agreements. The rules of the OBT agreement help distinguish between legitimate standards and technical rules and protectionist measures. Standards, technical rules and compliance assessment procedures must be developed and applied on a non-discriminatory basis, developed and applied in a transparent manner and, where appropriate, based on relevant international standards and guidelines. 2. Participation in technical expert groups is limited to people with professional experience in the field in question. The terms of ISO/CIS 2 relate to products, processes and services.
This agreement covers only technical rules, standards and compliance assessment procedures relating to products or processes and production methods. The standards set out in ISO/CIS 2 may be mandatory or voluntary. For the purposes of this agreement, standards are defined as voluntary and technical rules as mandatory documents. The standards developed by the international standardization community are based on consensus.
