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

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Introduction

The 10079 series of medical suction equipment comprised three parts which had many common

requirements. It was thought combining these common requirements into this one document would

prevent inconsistencies that result from developing three different parts with common requirements

and would make any future revision/amendment/corrigendum easier to manage.

This document contains those requirements that are common to electrically, manually and gas-powered

medical suction equipment and will be cross referenced by the separate parts.

4 General requirements
4.1 Risk management

4.1.1 An established risk management process, (e.g. ISO 14971), shall be applied to the design of the

suction equipment. The risk management process shall include the following elements:

— risk analysis;
— risk evaluation;
— risk control;
— production and post-production information.
Check compliance by inspection of the risk management file.

4.1.2 Suction equipment shall, when transported, stored, installed, operated in normal use and

maintained according to the instructions for use, present no risks that are not reduced to an acceptable

level using risk management procedures in accordance with ISO 14971 and which are associated with

their intended application in normal and in single fault condition.

NOTE A situation in which a fault is not detected is considered a normal condition. Fault conditions/

hazardous situations might remain undetected over a period of time and as a consequence, might lead to an

unacceptable risk. In that case, a subsequent detected fault condition needs to be considered as a single fault

condition. Specific risk control measures to deal with such situations need to be determined within the risk

management process.
Check compliance by inspection of the risk management file.

4.1.3 Where requirements refer to freedom from unacceptable risk, the acceptability or unacceptability

of this risk shall be determined by the manufacturer in accordance with their policy for determining

acceptable risk.
Check compliance by inspection of the risk management file.

ISO/DIS 10079-4:2020(E)
4.2 Usability

The manufacturer shall apply a usability engineering process to assess and mitigate any risks caused

by usability problems associated with correct use (i.e. normal use) and use errors (see IEC 60601-1-6

and IEC 62366).
Check compliance by inspection of the usability engineering file.
4.3 Clinical studies

Where appropriate, clinical studies shall be performed under the conditions for which performance

is claimed and documented in the risk management file. The clinical studies shall comply with the

requirements of ISO 14155.
NOTE Clinical data can be sourced from the following:
— clinical investigation(s) of the device concerned;

— clinical investigation(s) or other studies reported in the scientific literature of a similar device for which

equivalence to the device in question can be demonstrated;

— published and/or unpublished reports on other clinical experience of either the device in question or a similar

device for which equivalence to the device in question can be demonstrated.
Check compliance by inspection of the risk management and technical files.
4.4 Biophysical or modelling research

Where appropriate, validated biophysical or modelling research shall be performed under the

conditions for which performance is claimed and documented in the risk management file.

NOTE Biophysical or modelling research is the application of validated physical methods and theories to

biological problems. Examples include the use of a combination of models, i.e. mathematical, computer, physical,

cell and tissue culture, and animal, in a complementary and interactive manner to simulate the performance of

medical devices.
Check compliance by inspection of the technical file.
4.5 Test methods

The manufacturer can use type tests different from those detailed within this document if an equivalent

degree of safety is obtained. Alternative test methods shall be validated against the test methods

specified in Annex B.
5 Materials
5.1 Natural rubber latex

If any components of the suction equipment incorporate natural rubber latex the manufacturer

shall provide a specific justification for using this substance in their technical file. See also 9.3 g) for

additional marking requirements.
Check compliance by inspection of the manufacturer’s technical file.

use or capable of being cleaned and disinfected or sterilized as appropriate.
Check compliance by inspection of the technical file.

5.2.2 Parts of the suction equipment intended for re-use shall meet the requirements of Clause 7, as

appropriate, after those components have been subjected to 30 cycles of cleaning and disinfection or

sterilization as recommended by the manufacturer. [see 9.4 g)]
Check compliance by the tests given in Annex B.
6 Design requirements
6.1 General

6.1.1 Suction equipment classified as medical electrical equipment, as defined in IEC 60601-1:2005+A1:

2012, subclause 3.63, shall meet the relevant requirements of IEC 60601-1:2005+A1:2012.
