Dentistry - Multifunction handpieces (ISO 22569:2020)

This document is one of a series of standards describing the characteristics for identification cards as defined in the definitions clause and the use of such cards for international interchange.
This document specifies requirements for a high coercivity magnetic stripe (including any protective overlay) on an identification card and encoding technique. It takes into consideration both human and machine aspects and states minimum requirements.
Coercivity influences many of the quantities specified in this document but is not itself specified. The main characteristic of the high coercivity magnetic stripe is its improved resistance to erasure. This is achieved with minimal probability of damage to other magnetic stripes by contact while retaining read compatibility with magnetic stripes as defined in ISO/IEC 7811-2.
This document provides for a card capacity of approximately 10 times that of a card conforming to ISO/IEC 7811-6. The number of tracks has been increased to 6, each track being approximately half the width of tracks conforming to ISO/IEC 7811-6, located so that readers designed to read these high density tracks will also be able to read cards conforming to ISO/IEC 7811-2 and ISO/IEC 7811-6. Data is encoded in 8 bit bytes using the MFM encoding technique. Data framing is used to limit error propagation and error correction techniques further improve reliability of reading.
It is the purpose of the ISO/IEC 7811 series of standards to provide criteria to which cards shall perform. No consideration is given within these standards to the amount of use, if any, experienced by the card prior to test. Failure to conform to specified criteria is negotiated between the involved parties.
ISO/IEC 10373-2 specifies the test procedures used to check cards against the parameters specified in this document.
NOTE Numeric values in the SI and/or Imperial measurement system in this document may have been rounded off and are consistent with, but not exactly equal to each other. Using either system is correct but intermixing or reconverting values can result in errors. The original design was made using the Imperial measurement system.

Introduction
For many years, dental multifunction handpieces have been used in the field of dentistry to carry out
treatment in the oral cavity of the patient.
Multifunction handpieces are connected to dental units and provide the user with water, air and spray
for treatment purposes. Some multifunction handpieces provide also illumination of the situs.
Technological progress enables continual development of improved and new handpieces with simplified
handling and extended range of applications.
These handpieces are produced by the dental industry as high-quality medical devices under application
of quality management methods.
This document describes the applicable technical properties of products in order to maintain this high
level of quality.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO 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.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are

Introduction
For many years, dental multifunction handpieces (colloquially called “syringes”) have been used in the
field of dentistry to carry out treatment in the oral cavity of the patient.
Technological progress enables continual development of improved and new handpieces with simplified
handling and extended range of applications.
These handpieces are produced by the dental industry as high-quality medical devices under application
of quality management methods.
This document describes the applicable technical properties of products in order to maintain this high
level of quality.

Dentistry — Multifunction handpieces
1 Scope
This document specifies requirements, test methods, instructions for use and marking for multifunction
handpieces (colloquially called “syringes”) intended to be used in the oral cavity of the patient. The
multifunction handpieces are connected to dental units and provide the user with water, air and spray
for treatment purposes. Some multifunction handpieces provide also illumination of the situs.
This document does not apply to dental handpieces and motors, dental turbines, intraoral cameras,
contra angels, dental polymerisation lamps, powered scalers, powder jet handpieces, prophy handpieces,
suction cannulas and saliva ejectors.

During normal use, the housing of the multifunction handpiece shall not show any signs of water
leakage.
Test in accordance with 7.7.

Multifunction handpieces shall remain functional and safe, i.e. they shall not rupture or burst, when
subjected to a pressure 50 % higher than the maximal operating pressure recommended by the
manufacturer.
Test in accordance with 7.8.
5.14 Electrical power supply
These requirements apply only to electrically powered multifunction handpieces.

1) Nl/min indicates normal litres per minute, the amount of air that flows through a pipe calculated back to
2 2
“normal” conditions [0 °C and 1 atm or 1,013 25 bar (1 bar = 0,1 MPa = 0,1 N/mm = 105 N/m )].
