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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 7787/l was prepared by Technical Committee ISO/TC 106, Dentistry, in collaboration with the following international organization : FDI (International Dental Federation). 0 International Organization for Standardization, 1984 Printed in Switzerland SIST EN 27787-1:2000

It consists of two parts : Part 1 : Steel laboratory cutters. Part 2 : Carbide laboratory cutters. The various dimensional and other requirements specified for steel cutters are those considered important to ensure the interchangeability of these instruments. Attention is drawn to IS0 6360 which specifies a 15 digit number for the identification of dental rotary instruments of all types. 1 Scope and field of application This part of IS0 7787 specifies the dimensional and other requirements for the nine most commonly used steel cuttersl) which are predominantly used in the dental laboratory. Other characteristics of cutters, for example spiralled blades, cross-cut, are not covered by this Internation
