and also the large number of chemical plants, it is suggested to categorize plants and inspection accordingly, so as to optimize the inspection costs. 3. The general volume of routine inspection reports is estimated to be very high at the international level. In order to strengthen the operational methods of inspection, there is a need to define and establish norms for observation and information-gathering for various needs of inspection. The result of unification of the assessment system will be the speedy conclusion of reports by the organization of the convention. 4. The inspection revealed that although existing defined equipment is sufficient, yet there is a need for making the analysis equipment more mobile so that chemicals of low concentration can be identified on site. In this connection, efforts which are now under way by Finland to identify more efficient methods of analysis of chemical agents and the development of the means of instruments required should be valued and appreciated. 5. Among other important issues for the future is standardization methods of analysis and means of calibration of equipment, and establishment of a data base by the organization. It is therefore high time that measures be taken in this regard. CD/PV.573 12 (Mr, Nasseri, Islamic Republic of Iran) Mr. President, while I have the floor, I would like now to take the opportunity to make a few remarks with regard to the convention on chemical weapons. The Islamic Republic of Iran, having faced the bitter experience of the use of chemical weapons, has done its utmost to sensitize the international community in order to pave the way for an effective and comprehensive convention on the total elimination and prohibition of the development, stockpiling, production and use of chemical weapons. The history 
**Analysis**
The text discusses the convention on chemical weapons and the need for standardization and optimization of inspection methods, which suggests that it is related to the field of science and technology. Additionally, it mentions the development of instruments and equipment, which reinforces this hypothesis.
