IS0 133974:1995(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (I EC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 13397-l was prepared by Technical Committee lSO/TC 106, Dentistry, Subcommittee SC 4, Dental instruments. IS0 13397 consists of the following parts, under the general title Periodontal cure ttes, dental scalers and excava tars: - Part 7: General requirements - Part 2: Dental curettes - Gr-type - Part 3: Dental scalers - H-type - Part 4: Dental excavators It is anticipated of future parts. that additional types of instruments will form the subject Annex A of this part of IS0 13397 is for information only. 0 IS0 1995 All rights reserved.
