Part 2-76: Particular requirements for the basic safety and essential
performance of low energy ionized gas haemostasis equipment
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). 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. 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 IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

For brevity, IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012 are referred to in this
particular standard as the general standard. Collateral standards are referred to by their
document numbers.
The numbering of clauses and subclauses of this particular standard corresponds to that of
the general standard with the prefix “201” (e.g. 201.1 in this document addresses the content
of Clause 1 of the general standard) or applicable collateral standard with the prefix “20x”
where x is the final digit(s) of the collateral standard document number (e.g. 202.4 in this
particular standard addresses the content of Clause 4 of the IEC 60601-1-2 collateral
standard, 203.4 in this particular standard addresses the content of Clause 4 of the 60601-1-3
collateral standard, etc.). The changes to the text of the general standard are specified by the
use of the following words:
"Replacement" means that the clause or subclause of the general standard or applicable
collateral standard is replaced completely by the text of this particular standard.
"Addition" means that the text of this particular standard is additional to the requirements of
the general standard or applicable collateral standard.
"Amendment" means that the clause or subclause of the general standard or applicable
collateral standard is amended as indicated by the text of this particular standard.
Subclauses, figures or tables which are additional to those of the general standard are
numbered starting from 201.101, however because definitions in the general standard are
numbered 3.1 through 3.147 additional definitions in this document are numbered beginning
from 201.3.201. Additional annexes are lettered AA, BB, etc., and additional items aa), bb),
etc.
Subclauses, figures or tables which are additional to those of a collateral standard are
numbered starting from 20x, where “x” is the number of the collateral standard, e.g. 202 for
IEC 60601-1-2, 203 for IEC 6060-1-3, etc.
The term "this document" is used to make reference to the general standard, any applicable
collateral standards and this particular standard taken together.
Where there is no corresponding clause or subclause in this particular standard, the clause or
subclause of the general standard or applicable collateral standard, although possibly not
relevant, applies without modification; where it is intended that any part of the general
standard or applicable collateral standard, although possibly relevant, is not to be applied, a
statement to that effect is given in this particular standard.

IONIZED GAS ACCESSORIES including IONIZED GAS ACCESSORY CABLES and IONIZED GAS
For
CONNECTORS, separation between the circuits used to generate the IONIZED GAS and the
ENCLOSURE including SIGNAL INPUT PARTS and SIGNAL OUTPUT PARTS need not be subjected to
the dielectric strength test of 201.8.8.3.
The CREEPAGE DISTANCES and AIR CLEARANCES of the equipment other than IONIZED GAS
ACCESSORIES tested according to 201.8.8.3.101 and that are intended to prevent contact with
circuits used to generate the IONIZED GAS shall be as follows:
a) For an ionization frequency less than 1 kHz, the general standard applies.
b) For an ionization frequency between 1 kHz and 200 kHz, the greater value of the following
calculation is chosen:
13 f 17,3 f
CREEPAGE DISTANCE:
16− mm/kV, or 21− mm
200 200
6,14 f 8,2 f
AIR CLEARANCE:
mm/kV, or mm
9,14− 12,2−
200 200
where
f is the frequency in kHz.
c) For an ionization frequency higher than 200 kHz, the CREEPAGE DISTANCE and AIR
CLEARANCE is at least 3 mm/kV or 4 mm, whichever is the greater.
The reference voltage shall be the maximum peak voltage.

This requirement does not apply for components when the adequacy of ratings can be
demonstrated, for example by component manufacturers’ ratings or by the dielectric strength
test of 201.8.8.3.
This requirement described in 201.8.5.1.2 does not apply to IONIZED GAS ACCESSORIES. On the
other hand, the requirements and tests for IONIZED GAS ACCESSORIES are found in 201.8.8.3.
