Medical electrical equipment - Part 2-12: Particular requirements for basic safety and essential performance of critical care ventilators

ISO 80601-2-12:2011 applies to the basic safety and essential performance of a ventilator in combination with its accessories, hereafter referred to as me equipment: - intended to be attended by a professional operator for those patients who are dependent on mechanical ventilation; and - intended for use in critical care environments in a professional healthcare facility or intended for use in transport within a professional healthcare facility. ISO 80601-2-12:2011 is also applicable to those accessories intended by their manufacturer to be connected to a breathing system, or to a ventilator, where the characteristics of those accessories can affect the basic safety or essential performance of the ventilator. ISO 80601-2-12:2011 is not applicable to me equipment or an me system operating in ventilation modes intended for patients who are not dependent on mechanical ventilation. ISO 80601-2-12:2011 is not applicable to me equipment or an me system intended for those patients who are not dependent on mechanical ventilation. If a clause or subclause is specifically intended to be applicable to me equipment only, or to me systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to me equipment and to me systems, as relevant. ISO 80601-2-12:2011 is not applicable to continuous positive airway pressure (CPAP) me equipment, sleep apnoea therapy me equipment, home healthcare environment ventilators, ventilatory support me equipment, emergency and transport ventilators, anaesthetic ventilators, high-frequency jet ventilators (HFJVs) and high-frequency oscillatory ventilators (HFOVs). ISO 80601-2-12:2011 does not specify the requirements for me equipment that is intended solely to augment the ventilation of spontaneously breathing patients within a professional healthcare facility. ISO 80601-2-12:2011 does not specify the requirements for ventilators or accessories intended for anaesthetic applications which are given in ISO 80601-2-13. ISO 80601-2-12:2011 does not specify the requirements for ventilators or accessories intended for home care ventilators for ventilator-dependent patients which are given in ISO 10651-2. ISO 80601-2-12:2011 does not specify the requirements for ventilators or accessories intended for emergency and transport which are given in ISO 10651-3. ISO 80601-2-12:2011 does not specify the requirements for ventilators or accessories intended for home-care ventilatory support devices which are given in ISO 10651-6.

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 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 80601-2-12 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,
Subcommittee SC 3, Lung ventilators and related equipment, and Technical Committee IEC/TC 62, Electrical
equipment in medical practice, Subcommittee SC D, Electrical equipment. The draft was circulated for voting
to the national bodies of both ISO and IEC.
This first edition of ISO 80601-2-12 cancels and replaces the second edition of IEC 60601-2-12:2001. This
edition of ISO 80601-2-12 constitutes a major technical revision of IEC 60601-2-12:2001 and includes an
alignment with the third edition of IEC 60601-1.
The most significant changes are the following modifications:
 extending the scope to include the critical care VENTILATOR and its ACCESSORIES, where the characteristics
of those ACCESSORIES can affect the BASIC SAFETY and ESSENTIAL PERFORMANCE of the VENTILATOR, and
thus not only the critical care VENTILATOR itself;
 identification of ESSENTIAL PERFORMANCE for a critical care VENTILATOR and its ACCESSORIES;
 modification of the obstruction of the expiratory limb (continuing AIRWAY PRESSURE) ALARM CONDITION
requirement;
and the following additions:

 tests for ventilation performance;
 tests for mechanical strength;
 new symbols;
 requirements for a critical care VENTILATOR as a component of an ME SYSTEM;
 tests for enclosure integrity (water ingress);
 tests for closed suction survivability of the VENTILATOR;
 tests for cleaning and disinfection procedures;
PATIENT from the gas pathways.

Introduction


In this International Standard, the following print types are used:


 Requirements and definitions: roman type.


 Test specifications: italic type.

 Informative material appearing outside of tables, such as notes, examples and references: in smaller
type. Normative text of tables is also in a smaller type.
 TERMS DEFINED IN IEC 60601-1:2005, CLAUSE 3, IN THIS PARTICULAR STANDARD OR AS NOTED: SMALL
CAPITALS TYPE.
In referring to the structure of this standard, the term
 “clause” means one of the seventeen numbered divisions within the table of contents, inclusive of all
subdivisions (e.g. Clause 7 includes subclauses 7.1, 7.2, etc.);
 “subclause” means a numbered subdivision of a clause (e.g. 201.7.1, 201.7.2 and 201.7.2.1 are all
subclauses of Clause 201.7).
References to clauses within this International Standard are preceded by the term “Clause” followed by the
clause number. References to subclauses within this particular International Standard are by number only.
In this International Standard, the conjunctive “or” is used as an “inclusive or” so a statement is true if any
combination of the conditions is true.
The verbal forms used in this International Standard conform to usage described in Annex H of the ISO/IEC
Directives, Part 2. For the purposes of this International Standard, the auxiliary verb:
 “shall” means that compliance with a requirement or a test is mandatory for compliance with this
standard;
 “should” means that compliance with a requirement or a test is recommended but is not mandatory for
compliance with this standard;
 “may” is used to describe a permissible way to achieve compliance with a requirement or test.

An asterisk (*) as the first character of a title or at the beginning of a paragraph or table title indicates that
there is guidance or rationale related to that item in Annex AA.
The attention of Member Bodies and National Committees is drawn to the fact that equipment manufacturers
and testing organizations may need a transitional period following publication of a new, amended or revised
ISO or IEC publication in which to make products in accordance with the new requirements and to equip
themselves for conducting new or revised tests. It is the recommendation of the committee that the content of
this International Standard not be adopted for mandatory implementation nationally earlier than 3 years from
the date

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in
the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.

INTRODUCTION
This section of IEC 1241-2 describes methods for determining the minimum ignition
temperature of dust which are:
- method A: Dust layer on a heated surface at a constant temperature (clause 4);
- method B: Dust cloud in a furnace at a constant temperature (clause 5).
Method A determines the minimum ignition temperature of a dust layer on a prescribed
heated surface.
Method B determines the minimum ignition temperature of a dust cloud within a prescribed
heated furnace.
The test methods are of a general nature, and may be used for purposes of comparison,
but in certain industrial situations further tests may be necessary.
The methods for determining the minimum ignition temperatures are not suitable for use
with recognized explosives, for example, gunpowder, dynamite, or mixtures of substances
which may, under some circumstances, behave similarly.
Where there is doubt, an indication of the existence of a hazard due to explosive pro-
perties may be obtained by testing a very small quantity of the dust on a surface at 400 °C
or higher, located remotely from the operator.

ELECTRICAL APPARATUS FOR USE IN THE PRESENCE
OF COMBUSTIBLE DUST —
Part 2: Test methods —
Section 1: Methods for determining the minimum
ignition temperatures of dust
1 Scope
This section of IEC 1241-2 specifies two test methods for determining the minimum
ignition temperatures of dust.
The methods are not suitable for use with substances having explosive properties.
Method A (clause 4) is applicable to the determination of the minimum temperature of a
ace which will result in the decomposition and/or ignition of a layer of
prescribed hot su rf
dust of a specified thickness deposited on it. The method is particularly relevant to
industrial equipment with which dust is present on hot su rfaces in thin layers exposed to
the atmosphere.
Method B (clause 5) is applicable to the determination of the minimum temperature of a
ace which will result in the ignition of a cloud of a given sample of dust
prescribed hot su rf
or other particulate solid. The test is intended to be carried out as a complementary test
after determining the minimum ignition temperature of a dust layer by method A of this
standard.
NOTES concerning method B
1 Because the method of operation of the furnace gives short residence times for dust particles within it,
this method of test is applicable to industrial equipment where dust is present as a cloud for a short time.
This method of test is of small scale and the results are not necessarily representative of all industrial
conditions.
2 The method is not applicable to dusts which may, over a longer period of time than provided for in the
test method, produce from deposits gases generated during pyrolysis or smouldering.

NOTES
1 Because of the wide range of processes in industry, the ignition of dust layers may be dependent upon
local conditions. This method of test is not necessarily representative of all industrial conditions, where
account may need to be taken of such factors as the presence of thick layers of dust and of the distribution
of temperature in the environment.
2 When carrying out this test, it is essential that all necessary precautions be taken to safeguard the
health of personnel, for example, against the risk of fire, explosion, inhalation of smoke and any toxic
products of combustion.

the health of personnel, for example, against the risk of fire, explosion, inhalation of smoke and any toxic
products of combustion.

4.1 Preparation of dust sample
The sample shall be prepared so as to be homogeneous and representative of the dust
received for consideration.
The dust sample to be tested shall, in general, be able to pass through a woven metal wire
cloth or a square hole perforated plate test sieve with a nominal size of aperture of 200 gm

Any apparent changes noted in the properties of the dust during preparation of the
sample, for example, by sieving or owing to temperature or humidity conditions, shall be
stated in the test report.
4.2
Test apparatus
The apparatus is shown schematically in figure A.1. Essential details and pe rformance
requirements are given in the following subclauses. Methods of construction to enable
these requirements to be met are described in annex A.
4.2.1 Heated surface
The heated su rface shall consist of a circular metal plate and shall provide a working area
of at least 200 mm in diameter and be not less than 20 mm in thickness. The plate shall be
heated electrically and its temperature shall be controlled by a device for which the
sensing element is a thermocouple mounted in the plate near the centre and with its
junction within 1 mm ± 0,5 mm of the upper su rface and in good thermal contact with the
plate.
A similar thermocouple shall be mounted near the control thermocouple in a similar
manner, and shall be connected to a temperature recorder to record the temperature of
the su rface during a test. The heated surface and its control device shall satisfy the
following pe
rformance requirements:
a) the heated su rface shall be capable of attaining a maximum temperature of 400 °C
without a dust layer in position;
±5
K throughout
b) the temperature of the heated su rface shall be constant to within
the period of a test;
c) when the heated su rface has reached a steady state, the temperature across the
surface shall be uniform to within ±5 K when measured across two diameters at right
angles, by the procedure described in annex B. This requirement shall be satisfied at
nominal su ace temperatures of 200 °C and 350 °C;
rf
d) the temperature control shall be such that the recorded surface temperature does
not change by more than ±5 K during the placing of the dust layer, and it shall be
restored to within ±2 K of the previous value within 5 min of placing the dust layer;
e) temperature control and measurement devices shall be calibrated and shall have
±3
limits of inaccuracy of K.
4.2.2
Dust layer thermocouple
A fine thermocouple (0,20 mm to 0,25 mm diameter) of chromel-alumel or other suitable
material shall be stretched across the heated su rface, and parallel to it, at a height of
between 2 mm and 3 mm from it with the junction over the centre of the plate. This thermo-
couple shall be connected to a temperature recorder in order to determine the behaviour
of the dust layer during the test.
4.2.3 Temperature measurements
Temperature measurements using thermocouples shall be made either relative to a fixed
reference junction or with automatic cold junction compensation. In either case, calibration
shall satisfy the requirements of 4.2.1 e).

4.2.4 Ambient temperature measurements
The ambient temperature shall be measured by a thermometer placed not more than 1 m
ace, but shielded from heat convection and radiation from the surface.
from the heated su rf
The ambient temperature shall be within the range 15 °C to 35 °C.
4.2.5 Dust layers
Dust layers shall be prepared by filling the cavity formed by placing a metal ring of appro-
priate height on the heated su rface and levelling the layer to the top of the ring. The ring
shall have an internal diameter of nominally 100 mm and shall have slots at opposite ends
of a diameter to clear the test thermocouple (figure A.2). The ring shall be left in place
during a test.
A given dust shall be tested in a layer of 5,0 mm ± 0,1 mm depth. For predictive purposes
(see 4.6) a second depth (such as 12,5 mm ± 0,1 mm or 15,0 mm ± 1 mm) is useful.
Rings of appropriate depths will be required.
4.2.6
Formation of dust layer
The dust layer shall be formed without compressing it unduly. That is to say, the dust shall
be put into the ring with a spatula and distributed mainly with sideways movement of the
spatula until the ring is slightly overfilled. The layer shall then be levelled by drawing a
straight edge across the top of the ring. Any excess should be swept away.
For each type of dust, a layer shall be formed in the above manner on a sheet of paper
whose weight is known and weighed. The density shall be calculated from the mass of the
dust and the filled volume of the ring, and shall be reported.
4.3 Procedure
4.3.1
General
Ignition in particulate or porous solids exposed to elevated temperatures is generally
preceded by a more or less protracted period of self-heating (usually due to atmospheric
oxidation). Depending on the temperature of exposure, self-heating may result in no more
than a transient, though sometimes substantial, rise in temperature within the solid which
does not lead to propagation of combustion. Further, the "induction period" for ignition, at
temperatures near to the minimum required for ignition is usually many times greater than
for ignition in dust clouds or in gases and vapours (minutes or hours rather than seconds).
For both reasons the recognition of the minimum ignition temperature of dust layers is less
straightforward than for dust clouds or for gases and vapours. It is necessary especially to
be ce ain that failure to ignite at a given temperature is not merely because a test was
rt
terminated prematurely.

1241-2-1 © IEC:1994
The occurrence of ignition in a layer of dust on a surface at a given temperature depends
critically on the balance between the rate of heat generation ("self-heating") in the layer
and the rate of heat loss to the surroundings. The temperature at which ignition of a given
material occurs depends, therefore, on the thickness of the layer. Values determined for
two or more thicknesses of a given dust may be used for predictive purposes (see 4.6).
Following the recommended procedure, ignition shall be considered to have occurred if:
a) visible glowing or flaming is observed (figure 3a), or
a temperature of 450 °C, is measured or
b)
a temperature rise of 250 K above the temperature of the heated plate (figure 3c), is
c)
measured.
With regard to items b and c above, ignition shall not be considered to have occurred if it
can be shown that the reaction does not propagate to glowing or flaming. The temperature
shall be measured by thermocouple (see 4.2.2) It will usually be found that, provided the
temperature of the heated surface is high enough, the temperature in the layer will slowly
increase to a maximum value which may be in excess of the temperature of the heated
surface and then slowly fall to a steady value below the temperature of the heated surface
(figure 3b). This behaviour is evidence of self-heating in the dust layer and it may often be
accompanied by a discoloration of the dust but without active and visible combustion of
the layer. If the temperature of the heated surface is slightly higher, the temperature
measured in the dust layer will continue to rise instead of passing through a maximum.
Some materials exhibit more than one stage of self-heating, and it may sometimes be
necessary to prolong the test in order to fully explore this possibility. With organic dust,
combustion will usually take the form of charring followed by the appearance of
smouldering with glowing which will progress through the layer and leave a residue of ash.
With dust layers composed of certain divided metals, ignition may be characterized by the
relatively sudden appearance of highly incandescent smouldering combustion progressing
rapidly through the layer.
In the determination of the minimum ignition temperature for a layer of given thickness,
repeated trials are carried out, using a fresh layer of dust each time and with up-and-down
adjustments to the temperature of the heated surface until a temperature is found which is
high enough to cause ignition in the layer but which is no more than 10 K higher than a
temperature which fails to cause ignition. The highest temperature at which ignition fails to
occur shall be confirmed by continuing the test long enough to establish that any self-
heating is decreasing in rate; that is, the temperature at the point of measurement in the
layer is decreasing to a steady value lower than the temperature of the heated surface.
4.3.2 Method
The apparatus shall be set up in a position free from draughts, and preferably under a
hood capable of extracting smoke and fumes.

The temperature of the heated surface shall be adjusted to the desired value and shall be
allowed to become steady within the prescribed limits of 4.2.1 b). A metal ring of the
required height shall be placed centrally on the heated surface and this ring shall be filled
with the dust to be tested and levelled off within a period of 2 min. The recorder for the
dust layer thermocouple shall then be started.
The test shall be continued until it is ascertained either that the layer has ignited, either
visually or by the thermocouple recording, or has self-heated without igniting and is sub-
sequently cooling down.
If, after a period of 30 min, no self-heating is apparent the test should be terminated and
repeated at a higher temperature. If ignition or self-heating occurs the test shall be
repeated at a lower temperature, if necessary, prolonging the test beyond 30 min. Test

Avant-propos


L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de

normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée

aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du

comité technique créé à cet effet. Les organisations internationales, gouvernementales et non

gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec

la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO 80601-2-12 a été élaborée par un groupe de travail mixte du comité technique ISO/TC 121, Matériel
d'anesthésie et de réanimation respiratoire, sous-comité SC 3, Ventilateurs pulmonaires et équipements
connexes et le Comité technique CEI/TC 62, Équipements électriques dans la pratique médicale, sous-comité
SC D, Appareils électromédicaux. Le projet a été circulé pour le vote aux membres nationaux de l'ISO et de la
CEI.
Cette première édition de l'ISO 80601-2-12 annule et remplace la deuxième édition de
la CEI 60601-2-12:2001. La présente édition de l'ISO 80601-2-12 constitue une révision technique majeure de
la CEI 60601-2-12:2001 et s'aligne sur la troisième édition de la CEI 60601-1.
Les modifications les plus significatives sont les suivantes:
 extension du domaine d'application pour inclure non seulement le VENTILATEUR en lui-même, mais
également ses ACCESSOIRES, lorsque les caractéristiques de ces ACCESSOIRES peuvent affecter la
SÉCURITÉ DE BASE et les PERFORMANCES ESSENTIELLES du VENTILATEUR;
 identification des PERFORMANCES ESSENTIELLES d'un VENTILATEUR pour utilisation en soins intensifs et ses
ACCESSOIRES;

 modification de l'exigence relative à la condition d'alarme d'obstruction de branche expiratoire (PRESSION
RESPIRATOIRE continue);
et les ajouts suivants:
 essais des performances de ventilation;
 essais de résistance mécanique;
 nouveaux symboles;
 exigences relatives au VENTILATEUR pour utilisation en soins intensifs en tant que composant d'un
SYSTÈME EM;
