ISO 21671:2006 specifies the dimensions and other requirements for the most commonly used polishers which are used at the working place of the dentist and/or in the dental laboratory. ISO 21671:2006 is applicable to unmounted and mounted polishers.

ISO 3823-2:2003 specifies dimensional and other relevant requirements for the 17 most commonly used shapes of steel and carbide finishing burs, including a quality control and specifications for labelling of these instruments.

This part of ISO 7787 specifies the shape and dimensional characteristics, number of blades, type of toothing and run-out for the ten most common miniature carbide laboratory cutters, which are predominantly used in the dental laboratory.

ISO 1797-3:2013 specifies ceramic shanks of rotary instruments used in dentistry and gives measurement methods for the verification of the dimensions.

ISO 1797-1:2011 specifies shanks for rotary instruments used in dentistry and gives measurement methods for the verification of dimensions.

ISO 7711-3:2004 specifies the designation, colour code and grit sizes for diamond rotary instruments which are used commonly in a dental surgery. It applies to all types of dental diamond rotary instruments independent of type and shape. NOTE Attention is drawn to ISO 6360 which specifies a number coding system for the identification of dental rotary instruments of all types.

ISO 8325:2004 specifies methods for measuring the dimensional characteristics, neck strength and surface roughness of dental rotary instruments, such as burs, cutters, polishers, diamond and abrasive instruments. ISO 8325:2004 does not provide test methods for the characteristics of materials used for dental rotary instruments. NOTE For testing of these characteristics, see the respective product standards. ISO 8325:2004 is not applicable to dental root-canal instruments (see ISO 3630-1).

Specifies dimensional and other relevant requirements for the 14 most commonly used shapes of dental diamond instruments, including a quality control for these instruments. Replaces ISO 7711:1984.

Specifies requirements, packaging and marking for mandrels suitable for holding mounted and unmounted dental discs and polishers. Mandrels may be used for dental rotary instruments of different working diameters. For mandrels with mounted discs and polishers, the specification for the tread and screw do not apply.

Applies to all types of diamond rotary instruments independent of type and shape. Attention is drawn to ISO 6360-1 and ISO 6360-2 which specify a 15 digit number for the identification of dental rotary instruments of all types.
