PREAMBLE

Welcoming the international agreements and other positive measures of recent years in the field of nuclear disarmament, including reductions in arsenals of nuclear weapons, as well as in the field of the prevention of nuclear proliferation in all its aspects,

Underlining the importance of the full and prompt implementation of such agreements and measures,

Convinced that the present international situation provides an opportunity to take further effective measures towards nuclear disarmament and against the proliferation of nuclear weapons in all its aspects, and declaring their intention to take such measures,

Stressing therefore the need for continued systematic and progressive efforts to reduce nuclear weapons globally, with the ultimate goal of eliminating those weapons, and of general and complete disarmament under strict and effective international control,

Recognizing that the cessation of all nuclear weapon test explosions and all other nuclear explosions, by constraining the development and qualitative improvement of nuclear weapons and ending the development of advanced new types of nuclear weapons, constitutes an effective measure of nuclear disarmament and non-proliferation in all its aspects,

Further recognizing that an end to all such nuclear explosions will thus constitute a meaningful step in the realization of a systematic process to achieve nuclear disarmament,

Convinced that the most effective way to achieve an end to nuclear testing is through the conclusion of a universal and internationally and effectively verifiable comprehensive nuclear test-ban treaty, which has long been one of the highest priority objectives of the international community in the field of disarmament and non-proliferation,

Noting the aspirations expressed by the Parties to the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water to seek to achieve the discontinuance of all test explosions of nuclear weapons for all time,

Noting also the views expressed that this Treaty could contribute to the protection of the environment,

Affirming the purpose of attracting the adherence of all States to this Treaty and its objective to contribute effectively to the prevention of the proliferation of nuclear weapons in all its aspects, to the process of nuclear disarmament and therefore to the enhancement of international peace and security,

Have agreed as follows:

The standard event bulletin shall indicate numerically for each event the degree to which that event meets or does not meet the event screening criteria. In applying standard event screening, the International Data Centre shall use both global and supplementary screening criteria to take account of regional variations where applicable. The International Data Centre shall progressively enhance its technical capabilities as experience is gained in the operation of the International Monitoring System;

(c) Executive summaries, which summarize the data acquired and archived by the International Data Centre, the products of the International Data Centre, and the performance and operational status of the International Monitoring System and International Data Centre; and

(b) The provision of the data or products generated in response to ad hoc requests by States Parties for the retrieval from the International Data Centre and International Monitoring System facility archives of data and products, including interactive electronic access to the International Data Centre database; and

(c) Assisting individual States Parties, at their request and at no cost for reasonable efforts, with expert technical analysis of International Monitoring System data and other relevant data provided by the requesting State Party, in order to help the State Party concerned to identify the source of specific events. The output of any such technical analysis shall be considered a product of the requesting State Party, but shall be available to all States Parties.

National Event Screening

Technical Assistance

(a) In formulating their requirements for selection and screening of data and products;

(b) By installing at the International Data Centre, at no cost to a requesting State Party for reasonable efforts, computer algorithms or software provided by that State Party to compute new signal and event parameters that are not included in the Operational Manual for the International Data Centre, the output being considered products of the requesting State Party; and

Whenever additions or changes to the list of inspectors and inspection assistants are proposed by the Director-General or a State Party, replacement inspectors and inspection assistants shall be designated in the same manner as set forth with respect to the initial list. Each State Party shall promptly notify the Technical Secretariat if an inspector or inspection assistant nominated by it can no longer fulfil the duties of an inspector or inspection assistant.

20. The Technical Secretariat shall keep the list of inspectors and inspection assistants up to date and notify all States Parties of additions or changes to the list.

21. A State Party requesting an on-site inspection may propose that an inspector from the list of inspectors and inspection assistants serve as its observer in accordance with Article IV, paragraph 61.

22. Subject to paragraph 23, a State Party shall have the right at any time to object to an inspector or inspection assistant who has already been accepted. It shall notify the Technical Secretariat of its objection in writing and may include the reason for the objection.

The Technical Secretariat shall immediately confirm receipt of the notification of the objection and inform the objecting and nominating States Parties of the date on which the inspector or inspection assistant shall cease to be designated for that State Party.

23. A State Party that has been notified of an inspection shall not seek the removal from the inspection team of any of the inspectors or inspection assistants named in the inspection mandate.

24. The number of inspectors and inspection assistants accepted by a State Party must be sufficient to allow for availability of appropriate numbers of inspectors and inspection assistants. If, in the opinion of the Director-General, the non-acceptance by a State Party of proposed inspectors or inspection assistants impedes the designation of a sufficient number of inspectors and inspection assistants or otherwise hampers the effective fulfilment of the purposes of an on-site inspection, the Director-General shall refer the issue to the Executive Council.

25. Each inspector included in the list of inspectors and inspection assistants shall receive relevant training. Such training shall be provided by the Technical Secretariat pursuant to the procedures specified in the Operational Manual for On-Site Inspections. The Technical Secretariat shall co-ordinate, in agreement with the States Parties, a schedule of training for the inspectors.

104. The Technical Secretariat shall compile the results of the laboratory analysis of samples relevant to the purpose of the inspection. Pursuant to Article IV, paragraph 63, the Director-General shall transmit any such results promptly to the inspected State Party for comments and thereafter to the Executive Council and to all other States Parties and shall include detailed information concerning the equipment and methodology employed by the designated laboratories.

Conduct of Inspections in Areas beyond the Jurisdiction or Control of any State

106. The States Parties on whose territory transit or basing points are located shall, as far as possible, assist in facilitating the inspection, including transporting the inspection team, its baggage and equipment to the inspection area, as well as providing the relevant amenities specified in paragraph 11. The Organization shall reimburse assisting States Parties for all costs incurred.

107. Subject to the approval of the Executive Council, the Director-General may negotiate standing arrangements with States Parties to facilitate assistance in the event of an on-site inspection in an area beyond the jurisdiction or control of any State.

108. In cases where one or more States Parties have conducted an investigation of an ambiguous event in an area beyond the jurisdiction or control of any State before a request is made for an on-site inspection in that area, any results of such investigation may be taken into account by the Executive Council in its deliberations pursuant to Article IV.
