Quantities and units - Part 14: Telebiometrics related to human physiology

In IEC 80000-14:2008, names, symbols, and definitions for quantities and units of telebiometrics related to human physiology are given. This part of IEC 80000 encompasses quantities and units for physiological, biological or behavioural characteristics that might provide input or output to telebiometric identification or verification systems (recognition systems), including any known detection or safety thresholds. It also includes quantities and units concerned with effects on a human being caused by the use of a telebiometric device. International Standard IEC 80000-14 has been prepared by IEC technical committee 25: Quantities and units, and their letter symbols in co-operation with ISO/TC 12.

Grandeurs et unités - Partie 14: Télébiométrique relative à la physiologie humaine

La Norme Internationale CEI 80000-14:2008 donne les noms, les symboles et les définitions des grandeurs et les unités employées en télébiométrique relative à la physiologie humaine. Cette partie de la CEI 80000 contient les grandeurs et les unités concernant les caractéristiques physiologiques, biologiques et comportementales qui pourraient engendrer des entrées et des sorties pour les systèmes télébiométriques d'identification ou de vérification (systèmes de reconnaissance), y compris les seuils de détection ou de sécurité déjà connus. Elle contient aussi les grandeurs et les unités concernant les effets de l'utilisation d'appareils télébiométriques sur les êtres humains. La Norme internationale CEI 80000-14 a été établie par le comité d'études 25 de la CEI: Grandeurs et unités, et leurs symboles littéraux en collaboration avec le TC 12 de l'ISO.

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.

International Standard IEC 80000-14 has been prepared by IEC technical committee 25: Quantities and

units, and their letter symbols.
The text of this part of IEC 80000 is based on the following documents:
FDIS Report on voting

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

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: 12 ----------------------
SIST EN 80000-14:2009
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.
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

frequency ω is second to the power minus one, symbol s . Using the special names neper, symbol Np,

---------------------- Page: 13 ----------------------
SIST EN 80000-14:2009
– 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

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

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 most
...
