Introduction Mandrels are used for the support of rotary instruments. To achieve a general application, independent of the
17、 type of instrument, the standardization of mandrels is desirable. This will ease the usage of rotary instruments in dentistry. EN ISO 13295:2007 (E)31 Scope This International Standard specifies the requirements, the packaging and marking characteristics for mandrels suitable for discs and polisher
18、s used in dentistry. This International Standard uses the system of coding laid down in ISO 6360, which specifies a 15-digit number for the identification of dental rotary instruments of all types. 2 Normative references The following referenced documents are indispensable for the application of thi
19、s document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
