General-purpose criterion
The general-purpose criterion is an important concept in international law that broadly governs international agreements with respect to chemical weapons. Although the term is not found within such agreements, it is "regularly used" to describe the comprehensive nature of prohibitions regarding all chemical weapons.Scope
The scope of this criterion broadly governs the purpose of chemical agents opposed to specific objects. Therefore the prohibitions are not limited to a specific list, but encompass chemical weapons to include future incarnations.
