Chapter IV studies the discipline of international standardization under the WTO. It explains the negotiating history of both the Standards Code and the TBT Agreement and the provisions they established. This chapter focuses on the lack of an explicit definition of "international standard" and "international standardizing body" in the adopted agreements, and it explores the negotiation history and definitions in some drafts that provide guidance on the meaning negotiators intended for these two concepts. It relies on the information provided by the texts and their drafts, the case law and the principles in the TBT Committee Decision to propose definitions of "international standard" and "international standardizing body" and an analysis of the characteristics that an ISB and an international standard should have under the TBT Agreement.
