23、or 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 th
24、e 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. Internat
25、ional Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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 membe
26、r bodies casting a vote. International Standard ISO 10637 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 6, Dental equipment.

The aim of this International Standard is to ensure th
28、e reliable function of suction systems and the necessary safety in common usage and within normal ambient conditions. Any item of dental equipment recommended by the manufacturer for use in connection with suction systems should not render the equipment unsafe. EN ISO 10637:2000 Licensed Copy: sheff

30、al equipment. They are usually an integral part of a dental unit. This International Standard specifies performance and safety requirements as well as test procedures for high- and medium-volume suction systems. It also contains specifications on manufacturers instructions, marking and packaging. Th
31、is International Standard takes priority, where applicable, over IEC 60601-1, as specified in the individual clauses of this International Standard. This International Standard is not applicable to low-volume suction systems. 2 Normative references The following normative documents contain provision
32、s which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate th
33、e possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

36、d the following apply. 3.1 suction system active entity of dental equipment, including a suction machine, which enables an air flow to be induced which is designed to remove spray, liquids and solids from the mouth of the dental patient during dental treatment See Figure 1. NOTE It is a combination
37、of apparatus and accessories. Some components are described in 3.2 to 3.7. 3.2 suction device passive entity which can only induce an air flow when connected to a suction machine 3.3 air separator apparatus which separates liquids and solids from the suction air 3.4 filter apparatus which retains so
38、lids from the air and liquids passing through it 3.5 central system vacuum system having at least one suction machine which serves more than one device 3.6 accessories cannula, manifold, filter and/or mobile support 3.7 cannula connector cartridge, at the end of the hose part of the suction system,
39、intended for fitting of cannulae and for placement in the mobile support NOTE Also called a suction handpiece. 3.8 low-volume suction system suction system with an air intake of less than 90 l/min EN ISO 10637:2000 Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 16 07:00:41 GMT+00:00 2006, Uncon

41、s to which this International Standard is applicable are classified according to the air volume flowrate provided as follows: a) High-volume suction system Suction system with an air intake of more than 250 litres per minute (l/min) in each suction device. b) Medium-volume suction system Suction sys
42、tem with an air intake between 90 l/min and 250 l/min in each suction device. 4.2 According to the type of suction Suction systems are classified according to the type of suction as follows: a) Dry system Suction system in which, with an air separator, liquids and solids have been removed from the a
43、ir flow before the air enters the suction machine and in which the separator and the suction machine are two different devices. See Figure 1. b) Semi-dry system Suction system in which, with an air separator, liquids and solids have been removed from the air flow before the air enters the suction ma
44、chine and in which the separator and the suction machine are combined into one device. See Figure 1. c) Wet system Suction system in which solids have been removed from the air flow by a filter before air and liquid enter the suction machine, where they in turn are separated. See Figure 1. 4.3 Accor
45、ding to the type of protection against electric shock (see IEC 60601-1) Suction systems are classified according to the type of protection against electric shock by classes as follows: a) Class I equipment Equipment in which protection against electric shock does not rely on basic insulation only, b
46、ut includes an additional safety precaution which provides means for the connection of accessible conductive parts to the protective (earth) conductor in the fixed wiring of the installation such that accessible conductive parts cannot become live in the event of a failure of the basic insulation. b
47、) Class II equipment Equipment in which protection against electric shock does not rely on basic insulation only, but in which additional safety precautions such as double insulation or reinforced insulation are provided, there being no provision for protective earthing or reliance upon installation
