Part 14: Telebiometrics related to human physiology


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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to
be in conformity with an IEC Publication.
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.

0 Introduction
Subclauses 0.1 to 0.5 are text that is common to many Parts of ISO/IEC 80000. Some of this text is not
applicable to this Part of ISO/IEC 80000, but is included for consistency with other parts. Subclause 0.6
is specific to this part of ISO/IEC 80000.
0.1 Arrangement of the tables
The tables of quantities and units in ISO/IEC 80000 are arranged so that the quantities are presented on
the left-hand pages and the units on the corresponding right-hand pages.
All units between two full lines on the right-hand pages belong to the quantities between the
corresponding full lines on the left-hand pages.
Where the numbering of an item has been changed in the revision of a part of ISO 31, the number in the
preceding edition is shown in parenthesis on the left-hand page under the new number for the quantity; a
dash is used to indicate that the quantity in question did not appear in the preceding edition.
0.2 Tables of quantities
The names in English and in French of the most important quantities within the field of this part of
ISO/IEC 80000 are given together with their symbols and, in most cases, definitions. These names and
symbols are recommendations. The definitions are given for identification of the quantities in the
International System of Quantities (ISQ), listed on the left hand pages of the Tables in this part of
ISO/IEC 80000; they are not intended to be complete.
The scalar, vectorial or tensorial character of quantities is pointed out, especially when this is needed for
the definitions.
In most cases only one name and only one symbol for the quantity are given; where two or more names
or two or more symbols are given for one quantity and no special distinction is made, they are on an
equal footing. When two types of italic letters exist (for example as with ϑ and θ; φ and φ; a and a; g and
g) only one of these is given. This does not mean that the other is not equally acceptable. It is
recommended that such variants should not be given different meanings. A symbol within parenthesis
implies that it is a reserve symbol, to be used when, in a particular context, the main symbol is in use with
a different meaning.
In this English edition the quantity names in French are printed in an italic font, and are preceded by fr.
The gender of the French name is indicated by (m) for masculine and (f) for feminine, immediately after the
noun in the French name.
0.3 Tables of units
0.3.1 General
The names of units for the corresponding quantities are given together with the international symbols and
the definitions. These unit names are language-dependent, but the symbols are international and the
th
same in all languages. For further information, see the SI Brochure (8 edition 2006) from BIPM and ISO
80000-1.
The units are arranged in the following way:
a) The coherent SI units are given first. The SI units have been adopted by the General Conference on
Weights and Measures (Conférence Générale des Poids et Mesures, CGPM). The coherent SI units,
and their decimal multiples and submultiples formed with the SI prefixes, are recommended, although
the decimal multiples and submultiples are not explicitly mentioned.
b) Some non-SI units are then given, being those accepted by the International Committee for Weights
and Measures (Comité International des Poids et Mesures, CIPM), or by the International
Organization of Legal Metrology (Organisation Internationale de Métrologie Légale, OIML), or by ISO
and IEC, for use with the SI. Such units are separated from the SI units in the item by use of a
broken line between the SI units and the other units.

---------------------- Page: 8 ----------------------
80000-14 © IEC:2008 – 7 –
c) Non-SI units currently accepted by the CIPM for use with the SI are given in small print (smaller than
the text size) in the “Conversion factors and remarks” column.
d) Non-SI units that are not recommended are given only in annexes in some parts of ISO/IEC 80000.
These annexes are informative, in the first place for the conversion factors, and are not integral parts
of the standard. These deprecated units are arranged in two groups:
1) units in the CGS system with special names;
2) units based on the foot, pound, second, and some other related units;
e) Other non-SI units given for information, especially regarding the conversion factors are given in
another informative annex.
0.3.2 Units for quantities of dimension one, or dimensionless quantities
The coherent unit for any quantity of dimension one, also called a dimensionless quantity, is the number
one, symbol 1. When the value of such a quantity is expressed, the unit symbol 1 is generally not written
out explicitly.
EXAMPLE 1 Refractive index n = 1,53 × 1 = 1,53
Prefixes shall not be used to form multiples or submultiples of this unit. Instead of prefixes, powers of 10
are recommended.
3
EXAMPLE 2 Reynolds number Re = 1,32 × 10
Considering that plane angle is generally expressed as the ratio of two lengths and solid angle as the
ratio of two areas, in 1995 the CGPM specified that, in the SI, the radian, symbol rad, and steradian,
symbol sr, are dimensionless derived units. This implies that the quantities plane angle and solid angle
are considered as derived quantities of dimension one. The units radian and steradian are thus equal to
one; they may either be omitted, or they may be used in expressions for derived units to facilitate
distinction between quantities of different kind but having the same dimension.
0.4 Numerical statements in this part of ISO/IEC 80000
The sign = is used to denote “is exactly equal to”, the sign ≈ is used to denote “is approximately equal to”,
and the sign := is used to denote “is by definition equal to”.
Numerical values of physical quantities that have been experimentally determined always have an
associated measurement uncertainty. This uncertainty should always be specified. In this part of ISO/IEC
80000, the magnitude of the uncertainty is represented as in the following example.
EXAMPLE l = 2,347 82(32) m
In this example, l = a(b) m, the numerical value of the uncertainty b indicated in parentheses is assumed
to apply to the last (and least significant) digits of the numerical value a of the length l. This notation is
used when b represents one standard uncertainty (estimated standard deviation) in the last digits of a.
The numerical example given above may be interpreted to mean that the best estimate of the numerical
value of the length l when l is expressed in the unit metre is 2,347 82 and that the unknown value of l is
believed to lie between (2,347 82 – 0,000 32) m and (2,347 82 + 0,000 32) m with a probability
determined by the standard uncertainty 0,000 32 m and the probability distribution of the values of l.
0.5 Remark on logarithmic quantities and their units
The expression for the time dependence of a damped harmonic oscillation can be written either in real
notation or as the real part of a complex notation
–δt (–δ + iω)t
F(t) = A e cos ωt = Re (A e ),  A = F(0)
This simple relation involving δ and ω can be obtained only when e (base of natural logarithms) is used
as the base of the exponential function. The coherent SI unit for the damping coefficient δ and the angular
–1
frequency ω is second to the power minus one, symbol s . Using the special names neper, symbol Np,

---------------------- Page: 9 ----------------------
– 8 – 80000-14 © IEC:2008
and radian, symbol rad, for the units of δt and ωt, respectively, the units for δ and ω become neper per
second, symbol Np/s and radian per second, symbol rad/s, respectively.
Corresponding variation in space is treated in the same manner
–αx –γx
F(x) = Ae cos βx = Re(Ae ),  A = F(0) γ = α + iβ
where the unit for α is neper per metre, symbol Np/m, and the unit for β is radian per metre, symbol rad/m.
The taking of logarithms of complex quantities is usefully done only with the natural logarithm. In ISO/IEC
80000, the level L of a field quantity F is therefore defined by convention as the natural logarithm of a
F
ratio of the field quantity and a reference value F , L = ln(F/F ), in accordance with decisions by CIPM
0 F 0
and OIML. Since a field quantity is defined as a quantity the square of which is proportional to power
when it acts on a linear system, a factor 1/2 is introduced in the expression of the level of a power
quantity, L = (1/2) ln(P/P ), when defined by convention using the natural logarithm, in order to make the
P 0
level of the power quantity equal to the level of the corresponding field quantity when the proportionality
factors are the same for the considered quantities and the reference quantities, respectively. See IEC
1
60027-3:2002, subclause 4.2 .
The neper and the bel, symbol B, are units for such logarithmic quantities. The neper is the coherent unit
when the logarithmic quantities are defined by convention using the natural logarithm, 1 Np = 1. The bel
is the unit when the numerical value of the logarithmic quantity is expressed in terms of decimal
logarithms, 1 B = (1/2) ln 10 Np ≈ 1,151 293. The use of the neper is mostly restricted to theoretical
calculations on field quantities, when this unit is most convenient, whereas in other cases, especially for
power quantities, the bel, or in practice its submultiple decibel, symbol dB, is widely used. It should be
emphasized that the fact that the neper is chosen as the coherent unit does not imply that the use of the
bel should be avoided. The bel is accepted by the CIPM and the OIML for use with the SI. This situation
is in some respect similar to the fact that the unit degree (…°) is commonly used in practice instead of the
coherent SI unit radian (rad) for plane angle.
Generally it is not the logarithmic quantity itself (such as L or L ) that is of interest; it is only the
F P
argument of the logarithm that is of interest.
To avoid ambiguities in practical applications of logarithmic quantities the unit should always be written
out explicitly after the numerical value, even if the unit is neper, 1 Np = 1. Thus, for power quantities, the
level is generally given by L = 10 lg(P/P ) dB, and it is the numerical value 10 lg(P/P ) and the argument
P 0 0
P/P that are of interest. This numerical value is, however
...
