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.
International 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 member bodies casting a vote.
International Standard ISO 10079-3 was prepared by Technical Committee ISO/TC 121, Anaesthetic and
respiratory equipment, Subcommittee SC 8, Suction devices for hospital and emergency care use.
This second edition cancels and replaces the first edition (ISO 10079-3:1992), which has been technically revised.
ISO 10079 consists of the following parts, under the general title Medical suction equipment:
 Part 1: Electrically powered suction equipment — Safety requirements
 Part 2: Manually powered suction equipment
 Part 3: Suction equipment powered from a vacuum or pressure source
Annex A forms a normative part of this part of ISO 10079.

sterilized for re-use.
4.2  Equipment with filters intended for re-use shall comply with the requirements given in 8.1 to 8.7, as
appropriate, after the filters have been subjected to 30 cycles of sterilization as recommended by the manufacturer.
4.3  Suction tubing shall either be for single use or be capable of being cleaned, disinfected and/or sterilized as
recommended by the manufacturer.
4.4  Suction equipment incorporating a re-usable collection container assembly shall comply with the requirements
given in 8.1 to 8.7, as appropriate, before and after the collection container has been subjected to 30 cycles of
cleaning, disinfection and/or sterilization as recommended by the manufacturer.
5 Design requirements
NOTE The constructional requirements may deviate from those detailed in this part of ISO 10079 if an equivalent degree of
safety can be achieved.
5.1 Collection container
5.1.1  The inlet of the collection container shall have an inside diameter of not less than 6 mm and not less than the
maximum inside diameter of the suction tubing recommended by the manufacturer. The inlet shall not be
compatible with any conical connector specified in ISO 5356-1.
5.1.2  For suction equipment solely for field use which is intended to continue operating when the collection
container is full, the volume of the collection container shall be not less than 200 ml. For other suction equipment
intended solely for field use, the usable volume of the collection container shall be not less than 300 ml. For all other
suction equipment, including suction equipment intended for field and/or transport use, the usable volume of the
collection container shall be not less than 500 ml.
NOTE "Field use" of suction equipment is intended to cover use in situations outside of the health care facility at the site of
accidents or other emergencies. The use of suction equipment in these situations may expose the equipment to water
(including rain), dirt, uneven support, mechanical shock and extremes of temperature. “Transport use” of suction equipment is
intended to cover situations outside of the health care facility such as in ambulances, cars or airplanes. Use of suction
equipment in these situations may expose the equipment to uneven support, dirt, mechanical shock and a wider range of
temperature than normally found in health care facilities.
5.1.3  For suction equipment not intended for field use, one or more collection containers recommended by the
manufacturer and either for single-use or of a re-usable type, shall be used. For all collection containers, the level of
the contents shall be clearly visible in the position of normal use. The collection container shall be marked with its
usable volume, expressed in millilitres. For collection containers having a capacity of 500 ml or greater, an

ISO 10079-3:1999(E)
approximate indication of the volume of the contents shall be given by graduations. The intervals of the graduation
should not be less than 50 ml and not more than 250 ml.
5.1.4  The collection container shall not implode, crack or permanently deform when tested in accordance with A.2.
Following this test, the suction equipment shall meet the requirements of 6.1, 6.3 and 8.1 to 8.7, as appropriate.
5.1.5  The connectors for the suction tubing and the intermediate tubing shall be designed to facilitate correct
assembly or marked to indicate correct assembly when all parts are mated. Compliance shall be checked by
inspection.
NOTE Incorrect connections have frequently been a cause of spillover into the vacuum source and/or a loss of suction.
5.2 Suction tubing
5.2.1  When tested in accordance with A.3, the degree of collapse of the suction tubing supplied with the equipment
shall be less than 0,5 throughout its entire length.

equipment having a free air flowrate of more than 1 l/min. The pressure increase shall be less than 3,3 kPa/V in
10 s, where V is the total volume, in litres, of the collection container.
6.3.1.2  A re-usable collection container assembly shall meet the requirements given in 6.3.1.1, before and after
being subjected to 30 cycles of cleaning, disinfection and/or sterilization as recommended by the manufacturer.

ISO 10079-3:1999(E)
6.3.2 Collection containers for thoracic drainage
6.3.2.1  When tested in accordance with A.6.2, no more than three bubbles shall be observed in 10 s.

necessary, of at least 1,0, seated or standing 1 m from the vacuum indicator at an illuminance of 215 lx of white
(simulated day-) light.
NOTE Movement of a rotary analog vacuum indicator should be anticlockwise for an increase in vacuum.
6.7 Dismantling and reassembly
Suction equipment intended to be dismantled by the user (for example, for cleaning) shall be designed so as to
minimize incorrect reassembly when all parts are mated. After dismantling and reassembly, the suction equipment
shall meet the requirements given in 6.1, 6.3 and 8.1 to 8.7, as appropriate.
6.8 Mechanical shock
After suction equipment intended for field and/or transport use has been drop-tested in accordance with A.11, it
shall meet the requirements given in 6.1, 6.3 and 8.1 to 8.7, as appropriate.
If the suction equipment can be operated outside of its carrying case, it shall meet the requirements given in 6.1 and
8.1 to 8.7, as appropriate, after the individual parts of the suction equipment, excluding the cylinder and regulator,
have been drop-tested in accordance with A.11 and reassembled.

© ISO
ISO 10079-3:1999(E)
6.11.2 Suction equipment other than that specified in 6.11.1
In normal use, the maximum A-weighted sound pressure level (steady or peak value) of suction equipment other

The A-weighted background level of extraneous noise shall be at least 10 dB below that measured during the test.
7 Physical requirements
7.1 Dimensions
Suction equipment intended for field use, including any carrying case or frame, shall pass through a rectangular
opening having dimensions of 600 mm ´ 300 mm.
NOTE Suction equipment is often combined with resuscitation equipment which may make it impossible to define mass or
