Introduction
[2]

Previously the ISO 10079 series of medical suction equipment standards comprised parts ISO 10079-1,

[3] [4]

ISO 10079-2 and ISO 10079-3 which had many common requirements. It was thought that

combining these common requirements into this new part 4 would prevent the inconsistencies that had

resulted from developing three different parts with common requirements and would make any future

revision/amendment easier to manage.

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

medical suction equipment.

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; and
— production and post-production information.
Check conformance 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 is considered a single fault condition. Specific

risk control measures to deal with such situations can be determined within the risk management process.

Check conformance by inspection of the risk management file.

SIST EN ISO 10079-4:2021
ISO 10079-4:2021(E)

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 conformance by inspection of the risk management file.
4.2 Usability

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

[5]

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

[8]
and IEC 62366-1 ).
Check conformance 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; or

— 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 conformance 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 conformance by inspection of the technical file.
4.5 Test methods

Manufacturers 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.

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.
